LOFT CONVERSIONS

What we can help with.

Depending on the design, the work can include dormers or rooflights, windows, insulation, a staircase, partitions, plumbing, heating, electrics, plastering, joinery, flooring and decoration. We agree the drawings, materials, responsibilities and finish specification before construction.

THE DETAILS THAT MAKE THE DIFFERENCE

A room that feels like it belongs.

The best loft layout starts with how you want to use it. An extra bedroom needs privacy and storage;
a workspace needs daylight and quiet. We consider the roof, staircase and the floor below together,
so your new space feels connected to your home.

Headroom & layout

The existing roof shape and available height help determine which conversion options are worth exploring.

Stairs & circulation

A comfortable route upstairs matters as much as the new room. Stair positioning can affect the layout below.

Light & everyday details

Roof windows, bathroom layout, heating and storage all contribute to a space that works beyond the photograph.

EXPLORE THE POSSIBILITIES

Find the right fit for your home.

Rear dormer

Extend the roof to create usable floor space and comfortable headroom.

L-shaped dormer

Use a suitable rear roof addition to create a larger, more flexible layout.

Hip-to-gable

Reshape a sloping roof end where suitable to open up the space inside.

Mansard

Alter the roof profile to create a generous new upper floor, subject to design and approvals.

Rooflight / Velux-style conversion

Bring daylight into a suitable roof space using carefully positioned roof windows.

Bespoke loft layout

Plan a bedroom suite, bathroom, study or living space around the home and available roof space.
