Part 1: Obtaining planning approval in Green Belt and AONB for a new Self-Build Passivhaus dwelling
Amanda Henderson of Hetreed Ross Architects shares her experience…
The Route to Approval for a self-build Passivhaus in Green Belt
Volume is key
Time and Bat Surveys
Winning support with Contemporary Design
While I was designing the house I was also learning about Passivhaus and came to the conclusion that it would be worthwhile designing my own home to follow the Passivhaus principles and if possible to get it certified. It is not ideal in terms of form and orientation (more of that later) but I like a challenge and, even if we fail, we will hopefully end up with a building that performs better than most.
Our planning approval came with a condition that the building is designed to achieve “a level of energy performance at or equivalent to Level 4 of the Code for Sustainable Homes”, I am not sure what that is going to mean to us as the Code is withdrawn and “equivalent … energy performance”? I will need to understand what is meant by that, the Code uses SAP as a calculation method which is nothing like as accurate/rigorous as the Passivhaus PHPP method for energy performance (in my humble opinion) so hopefully it will be a walk in the park…
Next steps for the self-build passivhaus project which I will share in upcoming blogs
- What materials shall I use?
- How will I build it?
- Investigating mortgages for self-builds.
- Who will I appoint to help me?
- Will I need to put in a new planning application or revise the one I have as the scheme develops?
- Challenges of designing to Passivhaus principles on this project. Building warranties?
- ….and much more besides…
