Hi All,

 

On the verge of buying my first house and am currently looking into the extension I was planning on doing, incorporating a garage.

 

Only issue is after going down to the house to take measurements today I have doubts to that I can actually get the garage to efficiently work. There is 2.80m meters from the side of the house to the boundary, I am going to have to deduct 150mm for foundations which then leaves me an external brickwork face of 2.65m. THEN I have to deduct wall makeup which is 277mm (102mm ext. brick, 75mm cavity and 100mm block) leaving me with an internal width of 2.373m.

 

Will this dimension work, I fear not :'(

A standard ish sized motor would be about 2m wide ish focus megane etc. So you can get the car in but would probably have to exit via the boot. A mini might be ok but will still not ideal

What about a standalone garage? Can you extend the drive down past the house and build a free standing garage.

[carboy001]

There's already a standalone garage at the end of the drive but that'll be coming down for an extension regardless as the kitchen is far too small so there won't be any access after.

Basically I was planning an L shape extension around the side and rear elevations. Garage, utility and kitchen/diner.

i restored a mini in a 2.4 wide garage cavity is 100mm now aswell not 75

Is the garage single storey? Does it need to be insulated wall?

 

If so only do the wall 1/2 brick wide (102.5mm / standard garage wall thickness) so not a cavity wall - that would get you 175mm back and so 2548mm

What is the boundary - can you get permission to extend your foundations over the boundary and then make the garage wall the boundary wall?

Do you need a cavity wall for the garage, if it single storey a single skin block wall would work.  Obviously if your house is extending over the garage you haven't much choice.

If you search on town and country planning act you will find a simple concise guide, incl standard form letters detailing how to go about obtaining your neighbours permission to install foundations, on to their land which will allow you to build your garage externals to the cartilage, remember rain water, guttering down pipes etc will then overhang the curtilage, and agreement for that to happen will also need to be sought in writing. Just built one in the garden, but we have access through our garage on the side of the house. Hope this helps.

I'd build it with a cavity wall, it'll make it easier if you want to build above the garage

[carboy001]

Thanks for the input everyone, much appreciated.

 

I don't particularly want to go down the route of requesting permission from the neighbours to go across the boundary so quick after moving in to be honest and I don't think I would react positively if I was on the receiving end of it with the end result being the guttering overhanging etc.

 

I like the idea of the single skin garage as that'll give me more to work with as it's a good 900mm to the side of the mini then (not I'll attempting to butt it up against the wall haha).

 

As the extension does involve other parts of the house I've done a quick sketch up; black is existing walls, blue is traditional double skin for the other area's and the red will be the single skin for the garage. The only thing I would like to do is "future-proof" it and start the double skin in the foundations to top of slab so there is the opportunity to turn it into an study or something of that ilk further down the line when we move on and most likely rent it out. I take it this would be viable?

And to clarify it will only be single storey.

[CityEPete]

You could build the inner skin as stud work insulated with kingspan or similar to create a study in there without needing a wide/deep footing, that could be removed back to a garage in a weekend if needs be too.

My own garage is similar to what you suggest, one thing to calculate is that it will probably need some pillars to give the single skin wall some extra strength,mine has one about every 7 foot.

[Carlos W]

Where the guttering is will depend on which way the pitch runs.

[Rob Gavin]

I'd strongly suggest you speak to a local surveyor or architect who will give you the correct advice to suit you, the site limitations, existing house construction, local planning guidlines and building standards.

The link below might help. Permitted development (PD) relates to development that you can undertake without needing to submit a formal planning application. But you still need to submit plans for building control approval and may require a 'certificate of lawful development'. Previous extensions to the original property may limit your PD rights. Development up to or on a boundary usually requires a party wall agreement with your neighbours, and development on the boundary may anyway not be permitted if it doesn't fall within PD rights or planning guidelines.
