office shed project

[urbantus]

Im building a shed 4.8 m x 3.6 m in area
with a single pitch -pent-roof

Im building it on top of a concrete slab


Heres where Im up to so far

Floor

150x50 mm treated joists set on top of 100x100 mm treated timber bearers

joists at 400 mm centres
bearers laid in concrete base at 1800 mm apart set perpendicular to joists

50 mm polystyrene insulation fitted within joists and held in place by battens

joists covered by 18 mm water proof ply

Walls

100x50 mm softwood timber
115x15 mm treated softwood shiplap
breathable membrane
12mm stirling board osb
insulation within studwork
vapor barrier on inside
plasterboard

Pent Roof
150x50 mm rafters at 400 mm centres
2 no 150x50 mm purlings bolted togeather
18 mm waterproof ply
three layers roofing felt

[not sure yet about the pitch or the insulation detail for the roof]

My main concern is tha external water and or condensation does not lessen the life of my shed

I would appreciate any comments on the above points

Regards
