Green Building week at CAT and our students’ adventurous architecture project in the woods

In preparation for Green Building week (19th- 23rd September) Suzanne Burlton reports on some of the splendid sustainable architecture built by our Graduate School students

The impact of buildings is proportionally very large, accounting for 30-40% of energy use and a third of CO2 emissions. Green Building Week promotes sustainable building techniques which will reduce our impact on nature while also aiming to create buildings which provide social benefits. This involves design, materials and construction techniques, and here at CAT we don’t think these can be developed in isolation.

The late, great Arthur Erickson said that “Architecture doesn’t come from theory. You don’t think your way through a building.” Therefore, while a week in the design studio forms an important part of CAT’s ProfDip Architecture Summer School, it is the week spent building in the woods which often most transforms the way the students view their role in the overall process of design and construction.

One group designed a birdhide to be installed in the Coed Gwern woodland on the other side of the Dyfi Valley. The group were inspired by the environment to design a curving timber structure made up of slats which allows maximum visibility of birds while at the same time echoing the surrounding woodland in its materials and organic shape.

The idea originated two months earlier during a design charrette, and out of the five designs which resulted from the intense period of work, the one by student Bryn Hallett was chosen. The materials were ordered and prepared in order for work to begin in late August.

In the words of one student, good design aims to confront and dissect “the cultural, geographical and environmental uniqueness” of the site to create an “architecturally rich” intervention. This project was radically local, in line with the aims of Green Building Week to use architecture to restore and promote communities. The trees were felled in the area of the actual building site and sawn to the required dimensions in the Esgair Timber Company sawmill about half a mile up the forest track. Wood is a renewable building material which locks in carbon during its growth cycle and naturally filters the air.

Out in the woods there is little opportunity to use power tools due to the unavailability of grid connections, so the students had to be innovative in their constructions techniques. This gave them a real appreciation of traditional building techniques and how much modern construction relies on increasingly scarce energy resources, encouraging them to develop new ways of putting together their structure.

CAT’s ProfDip Architecture is a Part II course designed for those who wish to take Part III elsewhere in order to eventually register as practicing architects. We aim to be a centre of exemplary practice, training those who will design the buildings of the future to enable them to incorporate sustainable methods and materials for the benefit of the local community and the wider environmental context.

We welcome the opportunity to take part in Green Building Week in order to promote our shared aims of transforming the architecture and construction industries into ones which incorporate sustainability issues into their work at a fundamental level.
