I've just started converting my detached garage into a home cinema.
Lets face it modern cars dont fit in these small garages anyway !
(See photo 1)
I'm a project man so here's the plan....
To do this I must build a new brick shed, so am laying the foundations and drainage at the moment. (to store the junk from the garage!!!)

(See second photo for the foundations of the shed)
I kept a lot of junk, it was time for it to all go - got rid of it, cost £100 for a skip and away It went, cleared the garage.
(FIG JAM) I even impressed myself ! (please dont ask for a public definition)
lets just say it's "I'm Good, Just Ask Me")
Then I've booked a builder who will do the majority of the hard work, such as Install cabling, additional power, sound, wiring conduits
Put up studwork
Insulate the walls & ceilings
Plasterboard the walls,
Insulate the floor,
Lay more concrete on the floor.
Install heating
Because I'm in a conservation area, I cannot brick up the main doors, so it'll be an insulated stud wall behind, stopping the main doors from being used again ! that wall will become the screen
BTW the cost of the builder is probably about 1500 for a whole month,
so he'll be doing more than just the new Cinema !
The ex hates the idea want's me to not do it, but hey I want it, so tufff.....
The new shed will be 10ft x 10ft. the existing garage is 17 ft x 8 1/2ft wide. which means an ok sized cinema !. allowing for 2-3 feet in at either end.
More to follow....
