Hi there,
First posting so Hello!
I have a block garage with a flat roof...it is between my house and my boundary(the longest wall of the garage is the boundary)
I have been approved planning to change the roof to a pitched roof...pitch going down from house to boundary @ 22 degrees carrying slates.
The single wall that is currently my boundary wall is not the strongest and really not strong enough enough for a wall plate side abutment setup...so i have decided to look @ building a load bearing timberframe inside the blockwall...this will offer support for the roof, insulation,opportunity to damp proof and i will then plasterboard it...and as its a side abutment it will support my gutter also.
The garage is 24' * 12' and the roof will be regular slate.
Im wondering if someone can tell me what i should build the timber framed wall with(it does not have to look pretty as it will be hidden)...as in what size and spacing timber, and also if there should be a gap between this wall and my damproofed block wall...tips on what insulation to use be ggood to hear too.
Also as my garage is already quite narrow im trying to keep the width of the whole thing to a minimum.
Thanks,
Marty
