Hip-to-gable conversions
Space where hipped roofs limit it
Hipped-roof properties present a distinct challenge — the sloping ends reduce usable floor area. A hip-to-gable alteration changes that.
We visit your property and assess whether extending the side wall to create a vertical gable end will deliver the floor area and headroom you need. This is often combined with rear dormers or roof lights to maximise the new space.
Hip-to-gable conversions are common on 1930s semis and detached homes across Hertfordshire. We manage the structural engineering, roof reconstruction, and internal finishing — creating bedrooms, bathrooms, or home offices that would otherwise be impossible in a hipped loft.
Our guide to hip-to-gable loft conversions walks through how the side roof is rebuilt, and which hipped houses it suits.
What we deliver
Every detail considered
Gable wall construction
The hipped end is rebuilt as a vertical gable — matching existing brickwork or render for a seamless external finish.
Combined dormer options
Hip-to-gable works alongside rear dormers for maximum floor area — particularly effective on semi-detached properties.
Roof reconstruction
New rafters, ridge boards, and covering materials — the roof rebuilt to accommodate the altered geometry safely.
Structural calculations
Load paths, steel supports, and floor joist specifications — engineered for compliance and long-term stability.
Planning guidance
Advice on permitted development and planning requirements — with applications managed where necessary.
