Hi, I know it is impossible to say with any certainty, but I am at the stage of having a plot (my garden, so I already owned it) and a basic design (drawn by a relative who is a retired architect) and have been to pre-planning advice. The planning dept raised no objections to the plan, but have asked for a number of surveys (tree impact assessment, method statement, noise survey, land contamination survey ...) as well as technical drawings showing various things so to progress further I will now have to commit quite a bit of money. I will also need to find an architect to take the design to the next stage (building reg drawings and tender drawings). So we are talking £££ but so far I have no idea how much the build will cost beyond the m/sq estimates online, and I would love to hear any thoughts people have on this forum.
The design is for a single storey house with 2 bedrooms and one bathroom, 100 m/sq. It would have a living roof (needed for planning, and I like them) and has been designed with floor-ceiling windows in the main living area (this could change if prohibitively expensive). Materials - part brick, part timber clad. I don't know about construction methods (no technical drawings yet).
My budget is £300k - this is finite because I have retired, so I can't get a mortgage - my plan is to use my savings and release equity from my house (which I would then sell once the new house is ready to move into). I haThe only wriggle room we have on budget is that we could move into the house before all the finishing was done - so long as it was habitable, we could do the flooring etc later, once we have released money from the sale of the existing house. In terms of fees, I need to find an architect who is willing to just do the technical and tender drawings working from an existing design - I don't know how easy that will be or what they would charge. I don't feel capable of project managing so would be looking for a contractor or design and build company to take the project forward once planning permission has been granted.
All thoughts welcome!
