I am new to this forum and I am looking for some help if at all possible please.

My wife and I are looking to build a timber built extension to the side of our house the measurements are L 5.4 mtr and W 2.4mtr the height wil be just over 2mtr

If you imagine a L we will be using 2 exterior walls of the house and will build a frame around them. Inside the extension we will have a window and 2 doors aswell as frenchdoors (that are already in the lounge) and another door (already in the kitchen) I have read the terms on the planning website and from what I gather you don't need permission as long as it fits in certain guidelines. However I am a bit stumped about this

On designated land cladding of any part of the exterior of a dwelling and extensions with stone, artificial stone, pebble dash, render, timber, plastic, or tiles is not permitted development

I was hoping to clad it in plastic clip cladding and plasterboard the insides? do you know what I can use for the exterior?

Any advice would be greatly received.

talk yo your duty planning officer at yout local council for a definative answer.

if the exterior wall is within 1m of the boundary the external skin must be class 0 rated

Can you please tell us what you mean by class 0 rated, what materials are class 0 rated?

[andy01]

basically its a rating system for how quickly fire spreads / how resistant a material is to fire.

part b of building regs


brick is class 0
untreated timber is not
treated timber maybe


google "class 0 rated" to find materials which are suitable
