PhilC Posted January 3 Share Posted January 3 (edited) Hi Everyone, Hoping for some advice on submitting a building control application. As background, we got planning permission to convert a detached chalet bungalow to a full house with a new closed panel timber frame 1st floor and rooms-in-roof design. Once we tried to get contractors for the conversion involved and ran the numbers it became clear it would be cheaper and simpler to knock down and do a new closed-panel timber frame build. Thread discussion about that here. We are not changing the footprint and the rebuild would look the same from the outside as the planning permission we obtained. I've spoken to a planning consultant and the officer who did our original planning permission and apart from the detail as to why the need to switch they did not see any particular reason against it. One main difference is we would do this on a self-build mortgage, we have discussed this with a provider and they have done their checks and are ready for us to provide planning/BC. We need a full BC application for financing. I did the original planning application and I have been building a detailed 3D model to provide the various plans, foundation, drainage, structure, plumbing, electrical, fire etc. I have a qualified SE provide me with beam calcs etc. I've never done a BC application and the requirements for the plans seem more opaque than planning and I am wondering if I am over/underworking the detail necessary. The timber frame and steel will all be provided by an STA provider who will validate their design anyway, although they have said my model will reduce any estimation and some design costs from the project. I've laid out most of the structure now apart from the roof, but I am wondering how detailed this really needs to be? I would prefer to complete the BC app independently of a provider as I will save the considerable upfront cost and be able to take the design to multiple parties to compete. Appreciate any experienced thoughts about this, I want to make sure I am employing my time in the right way. Happy to share model pics if you would like, Thanks, Phil Edited January 3 by PhilC Link to comment Share on other sites More sharing options...
jack Posted January 4 Share Posted January 4 Have you thought about engaging a local architectural consultant to answer your questions? I'm sure someone would be happy to do so on an hourly basis. Link to comment Share on other sites More sharing options...

LiamJones Posted January 4 Share Posted January 4 I’ve just got approval on building control full plans. I mostly followed an example uploaded on here somewhere, but ended up reading every approved documented. I feel much more clued up now and less likely to make mistakes, especially given I’ve got the full plans approval! They were most interested in the structural drawings of part A. I did these by hand. The rest was mostly just written in a document saying I would do the things the approved docs said, and heavily referenced them. E.g, Quote all 1st floor windows to provide emergency escape as per approved doc B paragraph 2.10 Link to comment Share on other sites More sharing options...
LiamJones Posted January 4 Share Posted January 4 I might as well just upload what i did, i'm sure it'll help! I've redacted my address from the doc and drawings. Building Regulation Specification Redacted.pdf nwtc.01.pdf 1 Link to comment Share on other sites More sharing options...

It’s far more than I did, I just had sections of key areas and a floor plan! So I’m sure BC will be happy Link to comment Share on other sites More sharing options...
