Lofts, mansards and roof spaces, answered plainly.

A measured section tests usable standing height, floor buildup, insulation and stair arrival. Roof height alone does not tell you how useful the finished room will be.

Next We produce a section through the roof and the proposed stair.

They create roof accommodation in different ways and change the external form differently. We choose the roof approach through design and planning review, not just floor area.

Next We compare usable room shape, appearance, cost and approval route.

Its position affects the floor below as well as the loft.

We consider headroom, circulation, room loss and the escape strategy. This happens before bedrooms or bathrooms are fixed in place.

Next We review the stair across every floor it affects.

We check hot and cold water, pressure, drainage falls and ventilation. Structural loads and the layout are checked at the same time.

The position can have knock-on effects on the floors below.

Next We trace the proposed service routes before approving the bathroom position.

The engineer assesses the additional loads and the altered structure. Do not assume existing roof or ceiling joists can carry a new floor.

Next We carry out a structural feasibility review before detailed costing.

It may affect stairs, ceilings, service routes and the fire strategy on existing floors. We include those changes in the scope and programme from the outset.

Next We give you a schedule of work outside the loft itself.

We consider roof insulation, glazing area, shading and ventilation together. Any cooling proposal needs space, power, condensate drainage and room for outdoor equipment.

Next We agree a comfort brief for the room before selecting glazing.

Combining works can help with shared scaffolding and coordination. It also raises the importance of sequencing and weather protection.

We compare an integrated programme with separate phases before you decide.

Next Our project manager identifies shared access and temporary works needed.
