Having moved into a 1930's semi in the country about 20 months ago and have undertaken a lot of building work, and am now at a stage where I can put some effort into making a dedicated HC room from the garage. I originally had my eye on a smaller outbuilding but having researched for many hours on here I figured I may as well make use of the garage as it doesn't get used except for storing what could only be described as junk. I'm lucky enough for it to be detached from the house although it is about 3 feet away from the neighbours house. It will be a slow project as there are other small jobs around the house which I cant get motivated to do - like glossing window cills, etc - so will be using these jobs as bait for the Mrs to keep her happy! I've slowly collected some new and used bits for the project including a projector and a ceiling mount, two leather Lazyboy seats and a Sony 2400 amp and have some old bits which means I can get it up and running with a view to upgrading as and when funds allow. I am a bit of a hoarder and have spent the last 3 months sorting the garage out bit by bit and finally emptied the last of it out today with a trip to the dump. The garage originally had a dividing wall which I knocked down tonight and loaded it the hire van for another trip to a waste disposal site near me tomorrow. The garage is about 3m by 6m of a single skinned block design. It has an electric opening door and a window to the rear both of which I wish to brick up and a single door to the side at the rear. I envisage there may be issues with me blocking the window as it provides a means of escape however I have met the building inspectors on a number of times for the work done to my house and verbally ran through my plans and he did not seem to object to the window being blocked up. Hopefully if I have a mains fire alarm in there this will be sufficient to warn anyone in there of a fire. There is DPM around the existing blocks and with some good ventilation by way of an aircon unit this should help with any damp. I plan to batten and insulate with rockwool the walls floor and ceiling leaving the wall battens detached from the existing blockwork to provide some form of sound damping with the option of double boarding the walls if necessary. I haven't settled on many aspects like lighting, cabling outlet positions or screen type but am up for suggestions. My original thoughts are that I would have no use for the space behind a screen so may as well have a solid or painted screen. I'm thinking of plenty of power points and don't really want the basic equipment I've got in a cabinet on a rack behind or to the side would do me fine. I will be doing most of the work myself however my builder owes me at least 5 days and has said he will help out as he wants a poker room to use. So he will be doing the blockwork, finishing of electrics and plastering. Ive taken some rubbish photos on my phone but the Mrs has taken the camera to a work do so will get some better ones up later on in the week. Feel free to point out any deficiencies or other problems i may not have thought of as yet. Does anyone think I'll get some money for the door and opener?
