can you make an extension from the house to a detached double garage?

[goingtobefree]

I have seen a house online which is perfect apart from that it has a detached garage outside the house and was wondering if they can be connected, so a garage conversion can be done.

Unless it's a listed building, or in a conservation village. this should be ok under permitted development. It does depend on how far away the garage is but if you look up pd guidelines you should be ok.

Runty- what is pd guidelines

Permitted development - garage conversions fall under permitted development, check the rules below to see if the connecting link between house and garage would fall into this category.
I would advise a quick call to the planning officer in any case just to be sure as it will still need building regulations approval.
Planning Permission

Mm, will watch for any replies from buildery types as we are waiting for a quote for exactly this. Trouble we have, you may or may not be in same boat, is the roofline of the garage. The connecting room would go on a gable end wall of the main house, so easy-peasy that side, but garage has a hipped roof, which comes down quite low. Looking at taking the roof off the garage on the house-side, and replacing it with a pitched roof (I thin?, roof terms stay in my head about as long as jokes) to make a neater finish, but I am worried it's going to look odd from the front. Waiting to see costs before getting proper elevation drawings done....

All your questions answered here

The house we are thinking has garage,which is at a lower level when compared to the house, so not sure what can be done.I can't link the property as it is a very small community and we live not far away from the house. The house has few steps from the road but the garage is at a lower level on the road.

We've converted our garage into office for DH but it is a lower level to house. I'd love to attach it but am worried it will look strange from front. You get to it going across the deck so will probably compromise by getting something to cover the section of the deck that leads to it.

Maybe when DS is a teenager with a drumkit I'll be pleased we didn't attach it!

I was also thinking that it will look odd from outside. We have not viewed the property as we are not ready to buy yet.
