Question DetailsAsked on 8/6/2014

How much would it typically cost to bump out living room of a split ranch by 10'

The total additional space will be 16' X 10' . Living room is 16 ' X 11' which will convert to 16' X 21'. No plumbing, some electrical to add a few outlets per code and 4 recessed light and extend HVAC duct (forced hot air Gas heat) . This will include a Bay Window in the new addition, a vaulted ceiling and hardwood floor (to match existing floor) . Hardwood floor need not be finished, no painting.

Nothing high end -- Vinyl double pane standard grade Windows and siding.

The lower level / foundation /footing will need to be extended but the extended lower level need not be finished (need two half windows though)

The house is in Boston suburb, 1964 built.

Set back is not a problem (enough space).

I would say you need to get an Architect on board to verify code and planning and zoning compliance, and to prepare the plans and specs you will need for a building permit and for contractors to use to bid and eventually build it. The architect can also give you a construction cost estimate of what it willl cost, and discuss the cost drivers that affect your final cost.

Very rough ballpark, for your area I would say you are probably looking at the $200-250/SF range - if very simple maybe $150-175/SF range with the right contractor.

Thank you for the good answer. Do you know how much time it is expected to take for an A Grade Contractor (considering standard construction delays ). Is 2 months too high expectation ?

If the GC and all subs were available right when needed, you could get it done in 2 months after ground-breaking (not including any planning and zoning or building permit delays) - but personally I would target 3 and probably allow 4 in the contract before he is in default if I were you - which unfortunately may (depending on part of the country) mean inability to finish exterior painting if an early winter sets in, so you need a conditional clause in the contract to allow for finish painting in the spring if that happens. Make closing the property in and completing exterior a critical item in the contract - I would offer a bonus if ALL exterior work and the HVAC system is completed before your normal start of freezing weather, if applicable in your area.
