What is the difference between a hip-to-gable and dormer before work starts?

Hip-to-gable extends a sloped roof end to a vertical gable, increasing space. A dormer is a box extension on the roof slope. Both add room, but impact structure, appearance and scope differently. Ask what is included, how long the work may take, and what happens if extra issues appear.

Is there a minimum head height for stairs?

Stair design needs safe clearance and practical headroom. Exact requirements depend on regulations and layout. a loft-specialist can measure and advise on suitable options for your space. Photos and measurements can help the Loft Specialist give clearer guidance.

Can you convert a loft in a flat?

It depends on building structure, access to the roof space and permissions in the lease. Shared roofs and ownership rules may apply. a loft-specialist can assess feasibility, but ownership and permissions should be confirmed.

Will the roof need strengthening?

Some lofts need reinforcement to support new loads. The need depends on existing joists, roof structure and the planned use. a loft-specialist can identify likely requirements from the layout. Share the age of the property, access, and what you want to change so the Loft Specialist can plan the right approach.

Can you add storage in the eaves before work starts?

Eaves storage is common in conversions, using the lower roof areas. The layout should allow access panels while keeping insulation and ventilation intact. It helps to note any existing issues, recent work, and the areas involved.

How does lighting work in a loft?

Lighting plans depend on the use of the space, available power and roof structure. Options include ceiling lights, wall lights and roof windows. The scope should state what electrical work is included. Ask what is included, how long the work may take, and what happens if extra issues appear.
