TinRobot Posted October 19, 2022 Share Posted October 19, 2022 Hi - As a intro, we have moved to the North Norfolk Coast and are trying to convert a 1960s bungalow with views over fields and 10 minutes walk from the beach, into a Norfolk Cottage with a ultra modern extension to the side and rear. We have got planning permission and have started work but I lack the skill to be able to ensure the fabric is as good as I can achieve. We have also built a SIP annex that will act as a workshop and Gym but having issues with building control. As the decision was made to preserve an old apple tree we pushed the structure within a meter of the boundary (not helped that I have put a new boundary fence up in front of our boundary due to neighbour issues). I will create a post about this as the BI is demanding master board etc which I think is massively overkill when we have tower blocks full of people in clad buildings! I hate inconsistency. My main concern will be trying to insulate the home. The roof is being replaced and the new extension will have 100mm celotex (or similar( in the cavity to ensure building regs. Hoping to put in triple glazed windows as well. New floor is 150mm celotex but the old footprint is just a concrete slab. The old walls are thin (260mm) and the cavity has been filled with powdery white stuff that I believe is now banned and has slumped. As we have no gas in the village I want to try and up the insulation, make it airtight and as warm as possible. Finally we intend to put a load of solar panels on the roof with battery. This will help run our EVs and the ASHP. The floor will have thin insulation and underfloor heating. All good fun and I hope the vast experience here will be able to point me in the right direction. 1 Link to comment Share on other sites More sharing options...

Ferdinand Posted October 20, 2022 Share Posted October 20, 2022 Welcome. Ten minutes from the beach is wise in Norfolk ! If you are insulating heavily and airitght-ing, you *must* think carefully about ventilation, or you could end up with too much damp. What are your plans? When did you get PP, and do you have to / have you met the June 2022 Building Regs changes? Ferdinand Link to comment Share on other sites More sharing options...
