PROJECT DESCRIPTION
A straight forward denition of what it means to act sustainably triggered this design
project that is: take what we need to live now without jeopardizing the potential for people
in the future to meet their needs.
Construction materials demand a great deal from our natural resources. The rate at which
the world is using raw materials, such as cement, steel and wood, is increasing globally
and in New Zealand. The consequence of this process of manufacturing natural resources
and turning them into construction materials causes signicant pollution and energy use.
I found that one of the possible ways to reduce the overall energy consumption and
pollution is to look at the life span of construction materials. There is a one-way life cycle
of most building materials in New Zealand, rst they are extracted as raw materials,
then manufactured into building materials, then used for a building, but once the building
no longer serves a purpose, the building is demolished and the materials often end up
in a landll. This one-way life cycle has several consequences including lling landlls
and triggering further natural resource extraction. I discovered through my research that
construction and demolition waste is responsible for more than a quarter of the total waste
in landlls in the world.
To address this problem my proposed building uses recycled construction materials.
Through this proposal I aim to end the one-way life cycle of construction materials and turn
it instead into a loop by adopting recycling and reuse methods. B y adopting this proposal
and using these building methods, it would reduce energy use by reducing the demand for
new materials made from raw resources, it would reduce the waste in landlls by reusing
and recycling construction materials, and ultimately it would save natural resources for
future generations.
Christchurch will soon be in a major rebuilding process, but currently there is a great deal
of demolition in progress. This proposal is very appropriate for this situation, where there
is a massive amount of material waste created due to the on going demolition. Through
this proposal I aim to show how recycled materials could be used in future buildings.
The program for the building is a recycling centre which includes education, administration
and a recycling plant. The building is designed as a showcase for the use of material
waste and aims to promote recycling materials.
A key driver for this project is to minimize impact on the environment through the proposed
architecture. A range of demolished construction materials were used in this proposed
building including concrete debris and recycled timber. The overall architectural response
and experience is to expose and promote the many w ays of recycling different materials.
LIFE CYCLE OF CONSTRUCTION MATERIAL
This project relies on recycled construction materials, and aims to close the loop of construction waste by reusing and recycling otherwise wasted material.

HYBRID SPACE (EXHIBITION)
Hybrid space is the place where it becomes exible and hybrid in the aspect of its function. Derived conjunction between three
programs is to have exibility in its programmatic function including exhibition space and event space.

CONSTRUCTION AND DEMOLITION WASTE TREATMENT
This diagram explains how to treat construction and demolition waste so as to have le ss impact on environment. The i dea is that
there is embodied energy within a ll materials which is measure by the use of fossil fuel during its operation process. By recycling
construction waste the embodied energy of a material can be used more efciently and the life span of materials expanded.

THREE MBIUS STRIPS
Each strip represents a recycling method, they are joined
together to create overlap and integrated relationship.
Yellow = Concrete Debris Embedded Lime Mortar Wall
Red = Recycled Timber
Blue = Recycled Concrete Gabion Wall
THREE DIFFERENT PROGRAMS
There are three distinct programs and an overlap space.
Yellow = Educational space
Red = Administration space
Blue = Plant space
Green = Overlap and hybrid space
PROGRAM AND MATERIAL
Each strip is assigned a program and a material. The overlap
area creates a hybrid space which can be used for a range of
different programs including exhibitions, events and storage.
The Architectural response and experience is explored through
the use of different materials and programs.
