Good morning all!
We are due to begin our garage conversion in the next month or so but wanted to ask the question before we start digging.
Bit of background info: The garage is attached to the house and the back half of the garage has been converted (over 10 years ago) to an office and has been knocked through to the main house. The plan is to convert the front half of the garage into a WC/utility area. The foul drain is by the front door so the project will involve digging a new trench for a waste pipe, and also a trench for a water main from the kitchen at the front off the house, round the corner to the garage.
My question is, is there likely a foundation below where the garage door was? A few people I have spoke to have loosely mentioned the need to lintel between the two. I didnt give it much thought at the time, but as the project comes closer I'm starting to think about it. I have interpreted what they said as - The foundation won't continue under the garage door (no need for it originally), and we'll need 2 lintels to bridge the gap between the 2 foundations. This could work well as we would then run the services under this lintel.
As most garages do, it has a concrete slab. The plan was to put 100mm PIR on top of the slab with 22mm t&g flooring. I'm hoping this will be approved by BC.
Ps. Lots of homes on the estate have converted their garage and I can get it done under permitted development.
Cheers!
Tom
