ME Posted February 15, 2009 Report Share Posted February 15, 2009 I have a small flat roofed, single story extension on the back of our house. The furthest back room is just used as a spare room but I am soon going to use it for a home office. It has patio doors on one wall that open sidewards into the garden but I want an opening window facing down the garden. My question is - the rear wall that faces down the garden does not overlook anyone and doesnt already have a window in it, would I need planning permission to put a window in ?

Vince Green Posted February 15, 2009 Report Share Posted February 15, 2009 As your local planning office and if you don't, and I think you don't, they will give you a letter saying so which is more or less planning permission by any other name. Keep the letter and file it, even years later it may be needed if you sell the house. Quote Link to comment Share on other sites More sharing options...
V8mondo Posted February 15, 2009 Report Share Posted February 15, 2009 You will need planning permission. At minimum you will need to consult them. You will need scaled drawings of the elevations 1:100 and of the ground floor plan 1:50. As existing and as proposed. Take photos of the rear of the property too. Plus 1:500 and 1:1250 location maps - you can get them at www.ukmapcentre.com by email. You will only need the drawings for Planning, unless you want to be nice to your Building Control Officer. Also you will need a Building Regulations application *unless you have the window installed by a FENSA registered person/company*. If you decide to install it yourself, that is fine. You should go with a Building Notice application. NOT a Full Plans application. Saves time and you can begin work within 48 hours of notification. You will need to have the lintel inspected and also the window upon completion. You do not need trickle vents on repalcement windows. Advise them that the window will comply with Part L1B thermally at (1.8W/m2K), Part N if safety glazing is required - I think not- and if it is an inner room it must comply with Part B2 - means of escape, - window of 0.33m2 minimum opening.

V8landy Posted February 15, 2009 Report Share Posted February 15, 2009 (edited) I am in a similar situation for some work I want to do. Phone up you local planning and or reg deprt, mine where very helpfull. They gave me a form to fill in, and I included photos of the building and some basic scetches, from this they state they will get back to you within 10 working days with a yes/no on planning permission. Planning permission was eased of a couple of years back because the same amount of work is needed (in terms of paper work) for a porch extension as a full house. I suspect you will not need planning, but building regs is a def. Edited February 15, 2009 by V8landy Quote Link to comment Share on other sites More sharing options...

mikee Posted February 15, 2009 Report Share Posted February 15, 2009 you will not need planning, you will need building regs, they will want to see the lintel in place before its plastered over, the frame to be set 30mm back into the cavity, 28mm glazing, safety glass if within 800mm of the inside floor, if your BCO is very anal he may ask for wall ties in the reveals, he may want to check again when finished to check the lintel is plastered and the frame has been mastic sealed around the outside mikee Quote Link to comment Share on other sites More sharing options...

al4x Posted February 16, 2009 Report Share Posted February 16, 2009 the only addition to this would be if you are in a conservation area or the house is listed. Quote Link to comment Share on other sites More sharing options...
