We’ve found a property were interested in buying and adding a double rear extension on the back, a 3m ‘simple’ permitted development job. In theory it’ll allow us to have a much bigger kitchen/diner, possibly a study or play room and upstairs a larger family bathroom with either 2 doubles or 1 master & en-suite.
Firstly, is the general rule of thumb still £1k-2k per square metre for the ground + 50% more for the upper still reliable? And are these figures for a plaster finish with electrics & plumbing or do they include decorating/bathroom/kitchen fitting? I’m going a bit boss-eyed with all the different types of estimate that google throws up & would really appreciate some clarity!
Secondly, regarding permitted development we know the 3m double storey shouldn’t be a problem, but if we wanted to add a conservatory or further single extension later would we need planning permission? If that’s the case I’m wondering if it might be worth just doing it all at once under full planning.
We’re in Kent & it’s a semi detached property. Yet to measure up properly but as a guess: 3x5-6m out from the rear on both floors...maybe 2x3m as an additional single storey if we feel the need.
