The Hostry aims to tie together the old and the new and to reinvigorate the Cathedral, whilst complementing the Refectory built in 2004. Built within the footprint of the monastic Hostry it incorporates some of the remaining fragments of wall.

The mission statement:

‘A meeting place where people of all ages and backgrounds are made welcome and where learning and discovery enhance a visit to Norwich Cathedral’.

The brief was to:

-Create a building of such architectural merit that it would enhance and respect the Cathedral complex,

-Increase visitor access across the precinct

-Resolve disabled access

-Be sensitive to existing and theoretical archaeological remains present on site.

1.1.1 Use. Locutory.

The Locutory is situated just to the right of the Hostry and connected by the North courtyard. The locutory is used as a place to welcome visitors and tell them the story of Norwich Cathedral through a short film projected on the wall and plasma screens. An interactive touch screen computer is also located here which provides an interactive experience for visitors.

1.1.1 Use. North Courtyard (Japanese Garden).

The Japanese garden is a connecting point from the Hostry to the Loctory. It cannot be entered by visitors but is a visual addition to the building.

1.1.1 Use. Exhibition Space.

The exhibition space is frequently used, and draws visitors into the Cathedral whilst proving a space for local artists to get their work seen. The space is very flexible and can be utilised for other activities, however is primarily a gallery.

1.1.1 Use. Hostry Entrance.

The entrance to the building is a transitional mix between old and new. The space is open, light and inviting. The spacious layout accommodates for many visitors.

1.1.1 Use. Education Area.

The education room, is another community facility, that can be used for a multitude of different activities.

The First Floor of the Hostry highlights that the building is used as a community centre, a school, a library as well as the gateway to the Cathedral.

1.1.1 Use. Community Room.

The community room is very well used, the flexible space allows for maximum usage. Frequently hired out for lectures, and used weekly as a pre-school music group.

1.1.1 Use. Bridge.

The bridge really aids the Hostry in terms of light and space, by allowing double height spaces. It also creates an interesting architectural element.

1.1.1 Use. Music Library and Song School.

The music room and song rooms were vital additions to the Cathedral. The space, like most in the building, is light, spacious and well planned out for its purpose.

1.1.1 Use. Library.

The library is not in the new hostry building however does connect to it, and it a well used resource within the cathedral.

1.1.2 Amount.The majority of work was completed on site, due to the sensitive nature of the build and the original elements involved within the building.

The initial part of the build was focused on site, with the building of the new west wall, which was built upon the original remains. Once the west wall was built the work relied upon off site fabrication of the main structural elements.

The oak tree frame system, that supports the roof was designed and manufactured off site, however erected on site.

Putting the structural elements together on site was a delicate sequence. Starting with the columns going into position, the roof is then erected on top of this, and the first floor construction can be suspended. Then the glass walls are put in place, making the building watertight.

The majority of the Cathedral property is public access. However the vast majority of the surrounding buildings are private residence’s.

1.1.3 Layout.

The Cathedral and Hostry are situated in a heavily residential area and there is a strong sense of community there. The images highlight how central the Cathedral is within the local community.

1.1.5 Landscaping.The site map highlights how much green space there is on site and around the site. The outdoor grass area’s allow visitors to sit outside and enjoy the Hostry and Cathedral in all year round. The large expanse of green space also means there is nothing to distract from the cathedral’s architecture, enhancing the buildings.

Japanese garden

1.1.5 Landscaping.

1.1.5 Landscaping.The Cathedral attempts to integrate the outdoors and indoors wherever possible. There are large green open spaces both within the site and around it.

In 2009 a Japanese garden was designed and constructed in Norwich Cathedral Hostry. The concept for the garden was that it was to be very simple, just boulders and gravel, with a few stepping stones at one end.

The garden links the 11th century Cathedral buildings with the 21st century Hostry Visitor & Education Centre and features three boulders as its focal point which can be interpreted as a Buddhist triad or perhaps the Christian Trinity, given the position of the garden. The remaining stones are arranged as if they are all pointing to, or leading to, or perhaps being drawn towards, the triad.

The materials used in the Japanese garden consisted of: glacial boulders from North Scotland, Gravel (6mm silver- grey granite), Sawn grey sandstone (used as an edging material) and polished black pebbles. A traditional Japanese tripod and hoist was used to lift and position the boulders, which were wheeled in on a bespoke steel trolley designed for the purpose. Even in construction of the garden, the purpose and meaning was considered.

The intention of the garden is to bridge the new and the old spaces and also tobe an extension of the exhibition space.Almost an external piece of art.

1.1.6 Appearance.Hopkins Architects states that the building aims: ‘to recreate the volume of the medieval Hostry that stood on this site, while making as little impact as possible on the fabric of the existing buildings and archaeological remains.’(RW, 2007)

Using largely traditional materials and existing walls wherever possible costs were kept down and the buildings impact was minimal.

Environmental considerations were made throughout the design and build. Using natural ventilation, insulation and under floor heating, all of which minimised long term costs for the cathedral complex and provided an energy efficient structure.

The design and materials aim to embody the Benedictine Principles of: Worship, Hospitality and Learning.

1.1.6 Appearance.

The new materials are all very distinctive and whilst standing apart from the older materials of the other cathedral buildings, compliment them.

The roof is covered in local Anglican lead. Locally sourced materials were used wherever possibly. The roof was punctured with roof lights, which provided extra light in the internal spaces.

External oak louvres on the west elevation screen the Hostry from sunlight in the summer months to reduce solar gain.

The flooring was a combination of solid oak and limestone flagstones.

The large panels of glass throughout the building mean its light and airy. It also helps to integrate the old and the new, with views of the existing buildings.

Within the building there is a pebble evaporation layer, used as a ventilation method. This method was used and accepted as it is a traditional technique and relates to the history of the hostry and its place upon archeological remains.

1.1.6 Appearance.

The new exterior walls were built upon the original flint walls in Ancaster Limestone. All new external wall elements were required to be made in traditional solid masonry. The the remainder of the walls being fulled glazed, with the highest thermal and solar performance glass. The rubble stone walling was specified as ‘regularised random’. Ancaster Ragstone Limestone was chosen for the new walls with a wall-length Clipsham sill made of stone. A layer of lime putty was used to define the junction with the existing material and the wall was built by creating shuttering of stone one metre high at a time into which stainless steel reinforcing was lowered by crane and white cement poured, effectively creating a reinforced white concrete beam to take the weight of the roof.

1.1.6 Appearance.

The Hostry’s main materials were solid oak, local limestone from Lancashire and high performance glass.

The materials were used delicately and in a sensitive manner throughout, ensuring the distinction between the old and the new.

Fine steel-tipped finger-props holding the sand-cast lead roof, whose very rigid diaphragm is formed of glu-lam beams, steel purlins and plywood sheathing. The roof and first floor loads are carried down a grid of flitched oak columns into minimal pad foundations. A series of cruciform steel flitch plates at the sides of the columns were needed to support the first floor, the oak and steel working compositely to provide stiffness and support within the minimum possible diameter.

1.2.1 Access.

Vehicular and transport links- How building relates

The Hostry is easily accessible via all transport routes. This is due to:

- The Hostry being built parallel to the two main roads that access the cathedral, also keeping in fitting with the cathedral

- The entrance being easily visible from the road side and the visitors entrance

- Bikes racks are attainable via the main visitors entrance

- Bus stops are clearly visible and in close proximity to the Hostry, allowing visitors to come and go with ease.

1.2.1 Access.

1.2.2 Inclusive Access.

One of the main aims of the Hostry was to increase access, and improve disabled accessibility within the Cathedral.

The design incorporates wide aisles, lifts, corridors and doorways allowing wheelchairs and pushchairs to easily manoeuvre as well as large amounts of people. Wheelchairs are available for hire from the Cathedral if they are necessary.

Induction loops have been installed in the Weston Room in the Hostry, as well as in the Cathedral itself.

Disabled toilets are available on site with baby changing facilities.

Guide dogs are accepted everywhere within the Cathedral and can be provided with water.



The map above shows available access through the Cathedral. The Hostry is highlighted in red. The Hostry has complete disabled access.

The Cathedral can provide for any requirements that groups have, as long as they are told in advance.

The hostry has a large elevator to accommodate for large amounts of people, pushchairs and wheelchairs. It is positioned centrally, with plenty of space to manoeuvre in and out of it.

The floor surfaces are all smooth and on one level to make it easier for elderly people, young people, pushchairs and wheelchairs.

What is an accident?‘A discrete occurrence in the course of work which leads to physical or mental harm’, is the definition by Eurostat, European Statistical Office. An accident at work is an event that results in injury or death which happens in the work-place, due to lack of safety and preventitive measures.

2.1.2 Minimising Risk in Design.

Identify:The Norwich Cathedral Hostry has a series of actuated opening Vitral roof lights. Should a window regulator break, need replacing or whether a routine check or clean is in order, workers will need to access and walk on the roof of the building.Risk of falling has been reduced by the design of the building by incorporating a roof-safe system and a near horizontal platform for walking along.

The roof safe mechanism is designed to allow workers to be fastened onto the roof of the building without the risk of falling, thus minimising the risk of accident or injury to workers.

2.1.2 Minimising Risk in Design.

The North-East facing roof has a near horizontal working platform at 650mm wide to access a series of rooflights mechanical roof lights. Without any fall protection at either end of the building, the roof-safe string harness system prevents trips or falls down the 6.8m drop. The platform for the adjacent building is accessible by the same platform.

The South West facing roof has no roof lights, and therefore no platform. The integration of the platform to the roof structure suggests that the work platform is a design revision. The roof-safe harness system provides discreet means of worker protection, so is likely to be an architects design revision rather than a prescribed identification of the CDM coordinator as an aesthetic approach has been undertaken.

2.1.3 Minimising Risk in Construction.

Identify:The construction of the Norwich Cathedral Hostry was in two stages. Locally sourced oak and a steel cruciform were used as compos-ite columns in a tree support system. A steel beam and timber joist roof system clad in lead meant that a substantial weight was added to the relatively lightweight structural system. In turn causing problems in the construction phase for the contractors.

Risk of structural collapse due to the sudden stress applied to the composite system meant that a logical approach to construction methodology was required.


A bird-cage scaffold system was erected prior to constructing the roof and internal structural system.

External stonework was built upon the shallow pad footings.

I-Beam and timber roof was constructed then craned over the scaffold system to carry the weight of the leaded roof.

The internal tree structures were then erected underneath the completed roof.

Structural and roof elements fastened together.

Controlled removal of the scaffolding allowed the primary structure to gradually take the weight of the vast roof structure.

3.1.2 Local Planning Policy

Joint Core Strategies (JCS), Management Development Policies Plan, Site Allocations Plan, Area Action Plans are combined to create Norwich’s UDP. The main objectives of these are:

- to minimise the contributors to climate change and address its impact

- to promote economic growth, diversity, regeneration and reduce deprivation

- to allow people to develop to their full potential by providing educational facilities

- to make sure people have ready access to services

- to enhance transport provision to meet the needs of existing and future populations while reducing travel need and impact

- to be a place where people feel safe in their communities and that encourage the development of healthy and active lifestyles

- to positively enhance the individual character and culture of the area

- to protect, manage and enhance the natural, built and historic environment, including key landscapes, natural resources and areas of natural habitat or nature conservation value

Norwich’s UDP also includes a sustainability appraisal. This ensures that development is sustainable, responsible, well-designed and consistent with the councils strategies. This supports and enhances the heritage and environmental character of Norwich and provides for an appropriate mix of development which is well- related to existing services and meets the economic needs of the city.

These policies informed the architects on location for the hostry, building it on the archeological remains, which in turn informed the shape of the structure, and keeping it in fitting with the original building.

The policies on impact to climate change and the environment impacted choices of material used and structure. Many locally sourced materials were chosen to reduce carbon emissions in transportation. The materials have a long life span, such as the Oak beams that feature heavily in the design, and are also 100% recyclable. The building structure stands independently of the existing structure as to not interfere with it, effectively enhancing the historic environment without jeopardising its structural integrity.

3.1.2 Local Planning Policy

3.2 Building Response to Planning Guidlines

3.2.2 Building Response to UDP/ LDF

Social EconomicEnvironmental

The architects responded to these policies through three strategies.

Social

Architects considered green roofs to aid biodiversity

They integrated the landscape into the building form, reacting to the governments sustainable development strategy ‘A BetterQuality of Life’. By recognising the value of the natural environment the greenery is aimed at reversing the decline in wildlife and habitats the biodiversity.

Environmental

The building reuses elements such as the contemporary revival of the original archaeological form, the wall integrates the remnants of the original wall. Other than this the principles for the structural design have sought to minimise the impact of the new construction on the existing cloister building. A rigid structure was imposed via steel and oak cast H framed structures and masonry walls. These are sympathetic to the Cathedral context, remaining separate from the archaeological history, keeping to the conserva-tion nature of the policies Archaeological Hostry Footprint

3.2.2 Building Response to UDP/ LDF

Environmental

The building uses the land use cycle, considering orientation/ micro cli-mates and shelter. The Hostry has Brise Soleil installed on the western facade. Brise Soleil is a sustainable shading option. It works by stopping the rays of the summer sun from reaching the glazing and overheating the inside of the building. These are the horizontal elements protruding from the building

The design uses indigenous, recycled and recyclable materials, such as the oak beams, which are locally sourced to reduce carbon emissions in transportation

Encourages walking, cycling and publi transport by providing bike racks outside the Hostry and bus stops a mere 50 metres away

Goes further into the sustainable side by minimising the use and maxi-mum recovery of water. The building also uses geothermal energy for cooling.

4.1.2 Costing for Construction. Building Cost per Functional Unit.

The Functional Unit cost of a building expresses the cost of a unit based on its intended function. For example. The number of cars in a car park

To calculate the building cost per functional unit :

Cost per Functional Unit = Total cost/number of student rooms

Unit Cost Model = Cost of student room x number of rooms

Using Spons 2012, it is possible to find the building cost per functional unit by using the maximum capacity of each room in the building and the price range used for the room based on its intended function.

The functional unit cost however does not include VAT of 20% so this must be added on afterwards.

The preliminary costs in the 2012 edition are +11% which is included in the functional unit cost.

The location of the building must be added, by using spons a percentage is added to the cost of the build based on its location. For East Anglia the amount is -11%.

5.1 Critical Response.

5.1.2 Design and Access.

Use:

The Hostry design sticks to its mission statement and achieved what was originally wanted. The spaces and mixtures of materials work well to integrate the building the old and new, whilst bring-ing something modern to the cathedral. The upper floor spaces are flexible, allowing for the com-munity to connect with the building. This flexibility also makes the space ideal for functions, such as weddings and social events, therefore bringing in money to the cathedral.However, a lot of the open plan spaces in the building can be seen as redundant. An example of this is the entrance hall to the building, which becomes dead space. This space could be used to create more education facilities or enlarge the rooms already available.

Amount:

The first half of the work carried out on the building was done on site, such as the outer walls, roof and glass structures. This made the building water tight very early on in the design. The roof was balanced on scaffolding and as the interior beams, which were constructed off site , were added, the scaffolding was gradually removed, transferring the weight. This was the most effective way to construct the building as the connections with the existing cathedral wouldn’t have worked otherwise.

Layout:

The building is positioned in the original archaeological form. Because of this it is proportionate to the cloister and therefectory. The materials mean that it does not hide any of the original building and features, effectively combining the old and new. The materials also make it capable for the outdoor and indoor spac-es to integrate. The landscaping around the hostry also makes this possible.

5.1.2 Design and Access.

Appearance:

Materials used in the build are sensitive to the area and to the cathedral. The lead, limestone and oak beams are locally sourced. This means the structure is in keeping with the cathedral whilst bringing a modern twist through the materials. The glass makes full use of natural light and shading, whilst also allowing visitors to see the original features of existing surrounding buildings.

Access:

There were already good access routes in place due to the cathedral. However the Hostry has changed the site by providing a straight level platform into the building, which goes through to the cloister, refectory and cathedral, therefore making the old buildings WC compliant.


Slips, trips, falls and working at heights were the main health and safety issues with this build. To make it safer precaution-ary measures were built into the design for future use, such as maintenance of the structure. This is through a roof harness mechanism which is built into the structure. This mechanism is used to keep people from harm when they clean the roof. In addition to this the window ledges were extended to become working platforms. These additions were in the original plans of the building rather than a modification afterwards.

5.1.4 Planning.

The architects succeeded in sticking quite closely to the majority of planning policies in Norwich’s LDP. The main aspects they seemed to tackle were the sustainability appraisal and the non imposing gesture of this structure on the cathedral. Natural ventilation and solar shading were crucial to the sustainability factor, which was achieved by use of materials and layout, such as solar brises on the fully glass facade. When looking at other parts of the policies you see that the feeling of safety within the structure was also achieved by the copious amounts of light and open spaces. Additionally, education is an area of interest within the Norwich UDP, this building looks into this, providing flexible, light spaces to be used for education purposes and providing better teaching environments.

5.1.5 Finance.

The Hostry was a fully charity based project, the 10 year funding campaign raised £7.7 million and the Heritage Lottery Fund Grant £2.3. Because of this the money was collected over a number of years rather than in a lump sum and the architects had to stick to the budget as extra funding was not available. The average cost per metre squared in an average education centre is £12500, the Hostry costs £9277, showing the architects kept the costs low to stick to budget. Another way of sticking to the budget was through natural ventilation and solar shading through solar brises. The main income of the Hostry is through charitable donations to the centre.

The disadvantages of using the SPONS books to determine the costing of this building are that they’re limited to categories and make it difficult to breakdown room prices due to usage. As each room wasn’t specifically defined the total amounts calculated may be slightly off budget as the rooms closest in size to the ones in the Hostry were offices.
