Big time – UK’s largest passive scheme comes to Camden

The first phase of the hugely ambitious Agar Grove redevelopment in Camden was finished in April 2018. Not only is it the largest passive house scheme in the UK to date, it also aims to be a model for sustainable urban regeneration and for creating liveable spaces at the heart of our cities.


We are determined to tackle fuel poverty and reduce CO2 without the need for complex energy systems with high lifetime costs. The Passivhaus approach provides thermal comfort and air quality in a way that alternatives do not match. Although this can increase the initial capital costs, Camden Council – as both developer and landlord – believes that it will see the benefits of this approach, in higher build quality and reduced maintenance costs over the lifetime of the buildings.’
