Service overview
Use the space above
A loft conversion can add useful space within the existing home.
The success of a loft conversion depends on more than creating a room beneath the roof. Available height, structure, staircase position, daylight, insulation and connection with the floor below all influence the completed result.
Conversion possibilities
Ask about your roof space
Different roof forms support different approaches.
These are common loft-conversion configurations rather than recommendations for a specific property. Suitability depends on roof form, dimensions, structure and applicable requirements.

About Greenhaven Builders

Structural arrangement
Consider the roof and floor structure with the appropriate qualified professionals.
Staircase position
Identify how the new level could connect safely and practically with the existing home.

PROJECT NOTE

Not every roof space is automatically suitable.
Structure, headroom, staircase access, fire safety, insulation, ventilation, planning, building control and party-wall requirements may apply. The property and proposed conversion should be assessed by the relevant qualified professionals, authorities and advisers before work proceeds.
Loft conversion questions
Before transforming your roof space.
These answers provide a general starting point. Exact requirements depend on the property, roof and proposed conversion.
Ask about your loftNo. Suitability depends on the roof form, available height, dimensions, structure, staircase options and other property-specific factors.
The suitable approach depends on the existing roof, required space, property design and applicable requirements. An assessment is needed before selecting a conversion type.
Some conversions may fall within permitted development, while others require planning permission. The position must be confirmed for the particular property and proposal.
Staircase position depends on the existing layout, available space, headroom and applicable technical and fire-safety requirements.
Timescales vary according to the conversion type, structure, access, approvals, specification, site conditions and any issues discovered during construction.
