What's under a converted attic floor
Most loft conversions are decked with chipboard or plywood over joists that were either strengthened or newly installed as part of the conversion works. The key question isn't really what the deck is made of, but whether the joists underneath were sized with a habitable room's full load in mind, which should have been part of a proper building warrant application.
Sloped ceilings and dormer cheeks also reduce usable wall-to-wall width in places, which affects how boards or tiles should run to avoid awkward small cuts against the slope.
Where loft conversions are common in Fife
These conversions turn up across most of Fife's semi-detached and detached housing stock, particularly 1930s and post-war semis in Dunfermline, Kirkcaldy and Glenrothes where a third bedroom or home office has been added into the roof space over the years.
What we'd avoid here
- Fitting a heavy solid wood floor into a loft room without confirming the joists were sized for full habitable loading.
- Running large boards through a fixed loft stair without checking they'll actually fit round the turn.
Getting materials in
Fixed loft staircases are often the narrowest, steepest access point in the house, so material size and delivery sequencing usually need more planning here than for a ground-floor room of the same size.
Loft-specific checks
- Joist sizing relative to original conversion's intended use
- Building warrant evidence for the conversion, if available
- Access dimensions through the loft stair or ladder
- Sloped ceiling lines affecting board or tile layout
