Planning Question & Various

Pious14

About to start building and have a few questions. Would be grateful for a bit of advice:

1) Will I need to change my planning permission for moving a door and window at the back of the house and making a window smaller at the front?

2) For the second floor which is better - timber or concrete?

Thanks

1. yes, but presuming there a minor as you suggest your arch/ arch tech will probably be able to submit a letter explaining the alterations and avoid a full re-submission. though DO it now! don't wait till its built
2. that's a matter of opinion - define 'better'

Thanks for the reply. I suppose better for sound proof, insulation etc. I know concrete would be more expensive but what are the pros and cons of each

concrete pros:
increased fire safety
much greater sound proofing
more solid 'feel'
increased thermal mass
'easier' to make air tight

conc cons:
more expensive than standard timber floor
requires specialist sub contracting such as metal rail ceiling to underside.

We're getting quotes back at the moment, mostly for concrete, but timber frame looks like it is coming in slightly more expensive than concrete for a builders finish.

off-site timber construction v on-site wet trades, weather, then air-tightness, detailing, the knock on issues with trades etc. its hard to only use the tender price when comparing timber and conc methods. and certainly a difficult one to measure for a direct labour project..
