With a growing family (finally) ive realised I need more space in my fairly small house.
Being someone that basically never pays trades for anything i figured how hard can this be.
I have around 5.5x3m available, im going to do this 500mm off the neighbours fence.
My thought is, strip foundation, 600mm wide 1 meter deep.
Build blocks up to a level (dont know how high out the ground yet), dpc, treated sole plate. 6x2 timber frame, epdm rubber roof.
Im going to use the current window opening as the opening between lounge and new kitchen, new steel needed before break through? Im not altering anything but I have no idea what's there now.
Wall make up would be fiber board cladding/battens/house wrap/osb/6x2 frame full of insulation/vapour barrier/service battens/ foil backed plasterboard/fire line board?
Warm deck roof, 8x2 roof joists no insulation between rafters.
Drain i have a brick chamber, I can block off the old one to the kitchen waste, and drill and seal a new one into the chamber?
There's also the mains water stop which would end up just slightly outside the extension so id need to just protect the pipe to it before pouring foundation.
I have no idea where this runs from.
Current kitchen floor is 180mm above the current top level concrete patio, my initial idea was to level it all, insulation and then screed, could I not just have 6x2 sitting on the top level with damp proof membrane spanning the 6ft of so on the bottom level to a ledger on the new block wall, that would get me to the same finished floor height, would this be full insulation with no air gap? Alot more concrete pouring ect the other way.
Ill pay for electrics,plastering,fitting bifolds, gas to move flue but I shouldn't need much more.
From what I can gather BC need to see foundations,then the frame, roof,insulation then certs?
