PROJECT DESCRIPTION - BRIEF• Medium sized housing development,

comprising of new sustainable and innovative ideas.

• Semi-rural locale, green land with a blank canvas.

• A number of aspects of this brief changed throughout its development.

• This presentation will explain and express the rationale behind its conception.

RATIONALE

• Sustainable design on a large scale• Community integration• Self-sustaining• Attractive• Minimize materials, maximize impact• Suitable for all• Flagship community

CONCEPT HOUSE DESIGNKey Factors• Solid & Fast Construction• Energy Efficient • Flexible Design • Make the most of the location• Meet high standards• Fit for purpose• Life time home

CONCEPT NURSERY DESIGNKey Factors• Fit for purpose• Meet Users needs• Flexible Design • Meet Building regulations• Maximizing learning for students• Aesthetically pleasing

CONCEPT COMMUNITY CENTRE DESIGNKey Factors• Solid & Fast Construction• Energy Efficient • Flexible Design • Make the most of the location• Meet high standards• Fit for purpose

ICF – INSULATED CONCRETE FORMWORK• Quick, fast, solid and long lasting

construction• Lightweight, Compact transportation• Minimal waste on site• Excellent thermal properties and no

thermal bridges• Manufactured from Recycled material • BRE green guide ratings: A+• ICF Southern – Distributors located in

Storrington, West sussex

CHP – COMBINED HEAT AND POWER

• Energy Efficient – 90%• Cogeneration as standard with

trigeneration abilities.• Future for biomass incorporation• Can run on multiple sources of fuel• A++ Energy rating• Meets BREEAM standards• Bosch – Warndon, Worcester, WR4

9SW

TERMODECK & BISON HOLLOWCORE

• Solid, prefabricated planks• Large uninterrupted spans• Sound resilient• Multiple uses – Cable runs, HVAC

incorporation• Recycled aggregates• Excellent thermal mass for hot/cold

storage• Flexible design

MARLEY ETERNIT ASHDOWNE CLAY PLAIN TILES

• Traditional handcrafted • BRE Green Guide A+• Responsibly sourced• 60 year life span• Can be recycled into aggregates or

inert bulk fill• Multitude of different fixings and styles• Attractive mellow design

VMZINC STANDING SEAM ROOF

• BRE Green Guide A+• Responsibly sourced• 100 year life span• 100% recyclable • Less embodied energy• Low maintenance

RAINWATER HARVESTING• Large surface areas throughout the

site• Reduced water consumption by 50% • One connected system • Multiple uses – Allotments, flushing

cisterns, open space maintenance • Ability to convert to potable water• Reduced flooding risk with soakaways

and underground storage

KINGSPAN KLARGESTER • Independent self contained system• Low maintenance and running costs• Compact all in one system• Waste water can be fed to SuDs pond

through the reed bed for further filtration

• Gamma septic tank – Sludge can be used in many applications such as fertilization or for producing methane

SITE MATERIALS

• Ronadeck Resin Bound Surfacing• SuDs compliant• Resin from a botanic source• Low maintenance• Suitable for traffic areas

• Permeable Block paving – Forterra• Aquaflow & Aquaslab• Combined with soakaways • Helps break up the roadway

SUDS – SUSTAINABLE URBAN DRAINAGE SYSTEMS

• SuDS• Flood risk management• Water quality management• Amenity and biodiversity• Water resources• Community• Recreational• Educational

FUTURE ADAPTABILITY The Development has been designed with adaptability in mind

• Wattway• Solar paving that can be

implemented into existing roadways• 20m2 enough for single house

• PV panels or Evacuated tubes• Each building has the ability to be

equipped with these, without the roof structure being affected

FAILURES AND SUCCESSES• Successes

• Achieved end goal• Successful system integration• Realistic housing design• Sustainable• Community integration

• Failures• Time management• Lack in design renders• Site implementation into BIM• Too ambitious• Site analysis

QUESTIONS & DISCUSSION
