Do the TF companies quote from building regs drawings or can they do it from stage 1 drawings?

All of the quotes were from planning drawings. That's one of the reasons I expect the quotes to go up when they get to building regs and the lintels required over openings etc ...

 

Per @TerryE you need to be aware of cladding costs. We're looking at a mix of metal standing seam and charred timber and it is looking like it will cost not much less than the timber frame installed.

Rather than look at the floor area £.m^-2, why not compare the differences on the total surface area £.m^-2.

That reflects the amount of materials/work much more accurately.

That's how most suppliers quote, especially SIP and ICF.

Be great if members have those numbers to hand, I assumed it was a big ask so though sqm was easier!

In our case, I didn't employ an architect.  I used a 3D visualisation to plan out the layout to ~5 cm precision.  We had some particular (but not uncommon) requirements.  The whole house is  on 3 storeys including a warm loft (used as my live-in son's bedsit) and laid out on a general 3×2 tile with the front centre tile being a lofted  hall void with an open floating staircase spiraling up the two flights and the rear centre tile used for utility and bathrooms to simplify pipe runs.  I had to make damn sure that this would work as a space and comply with BRegs.  A local architectural technician converted this to basic plan and elevation drawing to our planning application.  I passed this AutoCAD drawing to the MBC AT and we went through 6 design cycles to get to the final drawing sets for both slab and TF / cassettes, UFH plans, etc.

 

I had to do a load of tweeks, e.g. slightly repositioning glulams to keep foul-water and MVHR runs clear.  We have 60° reveals on all of our windows so I did all of this detailing myself  -- We have a stone skin, so fenestration involved 3 separate subs (MBC for TF, local builder for skin, Internorm for the fenestration)  and any interface between three subs is always a recipe for trouble.

 

So I probably did a better job myself and also saved maybe £25K professional.  OK, this took a lot of focus and effort on my part, but thanks to MBC I didn't have to worry about cold bridging issues and how to make sure that the build was airtight.
