Garage extension

Not sure if this is the right forum - I did check but nothing else seemed to fit!
I am thinking about a single storey, single car garage extension plus adjoining porch to connect to the side of my house, and I have no idea whether I should give up on the idea or how long it would take me to budget for it.
I know it's how long is a piece of string but does anyone have any idea of likely costs? Has anyone had anything similar done?
I'd like for it to be brick (so the skin matches my house as much as possible which is red brick), single storey, single car width/length, with electrics installed, and not sure whether flat roof or gabled or hipped. Probably flat because it would be cheaper.
Another question: do I need planning permission for this as it would be at the side of the house? It would go up to the boundary with my neighbour that side, and there is already a driveway up the side of my house.

1st thing first - No you don't need planning as its classed at permitted development as long as it meets the following.
Side extensions to be single storey with maximum height of four metres and width no more than half that of the original house.
Check if your house has had any development rights removed. You will need building regs.
Costs - Work on £750/m2 as you're not doing a full fit out (eg no plastered wall, fixture and finishes). Based on this figure you may be able to do a pitched roof, but as you said a flat roof is cheaper. Depends if money or aesthetics are the main consideration but it may be possible to do both.0 -

I'm not saying you're wrong, but I'm sure I read something somewhere that said permitted development can't come within 1m of the boundary?0 -
The info is taken from here. No comment about boundary distances which does surprise me as well.
I initially thought you'd need permission as you were changing the external view of your property as seen from the front.
As many people on here tell you, it may be worth speaking to the local planning dept.

"Materials to be similar in appearance to the existing house."
- which our local council sees as meaning you cannot have a flat roof extension unless your house has a flat roof already. Unless perhaps you're going to tile it to match the existing.I am the Cat who walks alone0 -
Thanks for the replies theyre really helpful! Definitely seems a sensible idea to check with the planning department just to clear up confusion over a few bits and pieces so I'll do that next.
In terms of cost I'm guesstimating its 3m wide by 6m length from standard single car garage dimensions. So for 18 sqm that's around 13500? That's a fair bit more than I think I'd appreciated it might cost0 -
That cost may be slightly high but again speak to a local builder or neighbour who's had similar done.
In regards to the flat roof / pitched roof discussion i'd say that generally in newer housing developments they'd want a pitched roof and older housing you could do a flat roof. Or you could do a flat roof with a small mono pitch at the front to give the impression of a tiled roof.0
