SUSTAINABLE HOUSES
The built environment - the houses we work and live in - plays an important role in efforts to live more sustainably.
ECO Housing
Eco-building is one of CAT’s key areas of work. If you want to either build your own home or take on the renovation of an existing property, we can help in several ways. We demonstrate many building materials and techniques at our visitor centre, we sell many practical guides and we run both shorthands-on residential courses and postgraduate qualifications covering low energy building design.
Wooden Structures
Wooden structures are by far one of the most sustainable buildings to construct, this is due to the fact that wood is renewable and can be recylced. We can locally source it in this country and when we cut down a tree we can easilly plant more where it came from.
 
Wood is a brilliant material for sustainability as it can be burnt to create energy and crafted to create homes. The whole point of sustainability is that what ever material you use goes full circle from growth, to being used and then being feul.
Timber
Glass
Dirt
A design commercial approach to sustainable timber production is a practice we must embrace if we are to help the world get out of the climatic catastrophe that is surely coming. Timber is an ecologically sound product, we can in theory maintain a balance in the amount of timber we harvest to the amount of new trees that are planted. 
Glass is a very sustainable material as to have glass made in this country isnt that hard at all. Its made from heating up sand which turns to liquid. 
 
We can recyled glass via crushing it up and using it in hardcore and also insulation, called FOAMGLAS this means that in the future if the building is no longer neede the glass can be reused.
The wise building in the C.A.T. centre in wales cost the place 8 million, 4 million was raised via funding. The Architect Pat Bored designed it to used the mud around the site to create an inside structure which is now a lecture theatre. The sustainability of this is off the charts as mud can be reused and is everywhere.
 
The process was long because they had to wiat for each layer to dry and one time they didnt leave it creating a structural fault giving the project a 6 month delay.
