Sunday Telegraph Article 22.01.2012

The Sunday Telepraph featured an article on our proposal for an eco house in the picturesque location of Buckinghamshire which commented on the low energy design. Troy house is a proposal for a house on a piece of promontory land overlooking a lake, which was formely a gravel pit in the Metropolitan Green Belt area. The site is located 300m from the nearest house, so the occupants can enjoy complete seclusion. Currently, the site is shielded from veiw of the lake by Poplar trees, but they are to be felled due to disease. This generated the design in a half crescent shape, so all habitable rooms are opened up to the lake and the mass of bird life. The unusual form has 2 bedrooms at either end of the plan and central living accommodation that reflects the client’s wish to have the building used as holiday accommodation for their daughters and grandchildren when they come over from the Middle East to escape the heat.

BRE Passivhaus Competition 2012


Our entry for the BRE Passivhaus competition has been selected to go through to the final stages. The concept is to create a simple form with a glazed, south-facing facade, incorporating solar shading devices to capture and control solar gains, which produces a bright and comfortable internal environment.

Passivhaus or Code of Sustainable Homes?

There has been some recent debate pitting one against the other as standards to be adopted in the UK. PDS is firmly committed to the Passivhaus standards and principals, but there is room for both in our move towards the low energy and sustainable home.

The Code of Sustainable Homes has many good requirements, but it is not an assessment tool that fully evaluates the impact resulting form the lower and lower energy demands that will come with higher reduction targets. The SAP tool to assess energy is not based on design principals that consider fully the impact on building fabric and materials as we increase thermal efficiency and air tightness.
