Architect’s 1920s Passivhaus-inspired Haven – Garlic Row

Sun 17 Sep 2023, – Tue 3 Oct 2023, Various

Meet your host, Olly

Olly, an Architect and Certified Passivhaus Designer, set out to transform this once awkward & draughty 1920s gas-fired home into a delightful passivhaus-inspired haven suited to modern living. By carrying out energy modelling of the house and carefully sequencing the work to devise a step-by-step plan, Olly has been able to ensure that each stage of work is completed to a high standard, and where possible, has done much of the work himself. With phase 1 completed, Olly already feels much happier and healthier living in this renewed space and has calculated that his retrofit has resulted in a reduction of 89% Co2 emissions.

Olly says: “I wanted to ‘live my values’ with respect to the climate emergency.  As an Architect I wanted to get hands on with a project and I have really enjoyed the DIY aspects. I wanted to put the theory into practice and demonstrate to myself and others around me the benefits to the environment and to human health of the Passivhaus approach.”
