What makes a PSF shed house different
Every element is engineered for long-term habitable performance — not just meeting minimum code.
90mm Stud Frames
Predominantly 90mm steel stud framing — stronger than standard 64mm or 76mm frames used in most kit sheds. Delivers superior structural integrity and straighter walls.
Kingspan Thermal Wrap
Full roof and wall thermal wrap eliminates thermal bridging. Keeps your shed home cooler in summer, warmer in winter, and condensation-free year-round.
Welded Connections
Critical frame connections are welded, not bolted. No loosening over time, no frame movement, no gaps appearing in cladding — the structure stays as-built for decades.
Full Class 1a Compliance
Designed and engineered as habitable dwellings under the National Construction Code. Full council-ready documentation for your building approval.

Why standard shed homes fall short — and how PSF solves it
Common problems with cheap shed homes
- • 64mm frames flex and bow — nail pops in plasterboard within years
- • No thermal break — condensation forms inside walls, causing corrosion and mould
- • Bolted connections loosen from thermal cycling — gaps appear in cladding
- • Generic engineering doesn't account for your actual site conditions
How PSF does it properly
- • 90mm stud frames — 40% thicker than standard, walls stay true
- • Kingspan thermal wrap roof + walls — zero condensation, no thermal bridging
- • Welded critical connections — frame geometry holds permanently
- • Site-specific engineering for your exact location, wind zone, and soil conditions
PSF insight
"A shed house is still a house. People live in it. The frame can't flex, the walls can't sweat, and the doors need to close properly in year ten. That's why we use 90mm studs and Kingspan — not because it's cheaper, but because it's right."
