My house is on the corner of a block so is at right angles to the house behind. This house has a double storey extension close to the boundary. My garage is also close to the same boundary. Am I allowed to raise the height of my garage roof to 4metres ?

Can we have a sketch or anonymised pics, please?

Pic 1 from my house

pic 2 my garage and neighbours extension

I couldn’t annonymise the pics !

So in pic 2 you are already in the process of raising the height of your garage roof.

 

I don't see the neighbours extension having any relevance to what you are doing, but it is outside what is allowed by permitted development so you should seek planning permission.

 

If you don't then it's possible the planners may enforce it's removal.  Worst case you put it back as it was.  What to you want to achieve with this raised roof? 

The Permitted Dev'p't conditions say: ''

• No outbuilding on land forward of a wall forming the principal elevation.
• Outbuildings and garages to be single storey with maximum eaves height of 2.5 metres and maximum overall height of four metres with a dual pitched roof or three metres for any other roof."

I don't think we can see your (house's) principal elevation from those pics, can we? If your house is in the 'invisible foreground' of pic one then surely the principal elevation is at 90 degrees to the front of the garage, and therefore surely the garage is not in front of it... (I think...!)

 

 

 

Sorry I’m not sure of the term  ‘principal elevation’  or  ‘invisible foreground’. The garage and the neighbouring house is at the bottom of my garden so my house is not in the pic. The garage faces the same road as the neighbouring house so it’s running alongside the extension. So no it’s not in front, it’s at the side. - my mistake!
I probably mistakingly thought that because the aforementioned extension seems to be outside permitted development, i could use that as an excuse for raising my garage roof to 4 metres. Is that not the case?

I wanted a raised roof to add a mezzanine for storage

I’ll just have to take it down !

Your choices are apply for planning permission before continuing.  Or just do it.

 

If the planners notice and try and enforce it, then your first course of action is apply for retrospective permission.  Only if that is refused (and an appeal is refused of you try that) that you will have to revert to what was there before.

 

My gut feeling is it won't be refused.

 

Out of interest how long has the garage been there?

I’ve been here since 1996 and the garage was here then.

Thank you for your replies guys, I really appreciate your time.

You are limited to an overall height of 2.5m and so anything more requires Planning. Note this only relates to a replacement roof. It does not mean the existing has to be reduced.
