We want to extend, preferably quickly using SIPS (structural insulated panels) or similar. The problem we have is that we can't see any builders locally that say they use them, and there's a very limited number of companies that will do the whole extension rather than just supply the modules.
We have found Vita Modular who will do a full design and build service including foundations, electrics, flooring etc but there doesn't seem to be many others.
This is partly because we are about 70% sure we want a 2 story extension and there are a few companies that just do single story.
Has anyone used Vita Modular and can comment? Or used other companies they can recommend?
We are in Cambridge but interested in hearing about what you've done anywhere else too as we don't know anyone who has done this!
We have found lots that will supply and instal the actual modules, but I'm not sure we would want to project manage the foundations, building regs, tradesmen etc. I guess we would need to find a builder or architect or both that would be willing to work with SIPS to use these companies, but at that point probably easier to just go traditional.
Oh, in case relevant to any comments, it's a kitchen diner rear extension, 7m wide and about 4m out.
