Loft Conversions in Dorking and Across Surrey

Turn an Underused Loft Into a Practical Part of Your Home
A loft conversion can add valuable habitable space while retaining the existing footprint of your property. Johnson Construction & Building Ltd undertakes loft conversions throughout Dorking and the wider Surrey area.
With roofing, structural carpentry, joinery and supporting trades available through one team, the different stages of the conversion can be coordinated from the first site discussion through to the finished room.
- Rooflight, dormer, hip-to-gable and mansard options
- Structural timber and roofing work coordinated together
- New stair access and internal finishing
- Suitable projects considered throughout Surrey
A Design Suited to Your Roof and Property
The right conversion type depends on the existing roof shape, available head height, planning requirements and how the finished room will be used.
Rooflight Conversions
Use the existing roof shape with carefully positioned roof windows and internal alterations.
Dormer Conversions
Create additional usable floor area and head height with a new projection from the roof.
Hip-to-Gable Conversions
Extend a sloping roof section to form a vertical gable and increase internal space.
Mansard Conversions
A more substantial roof alteration that can create generous room proportions where appropriate.
Create the Space Your Household Is Missing
The layout, insulation, natural light, access and services should all be planned around the intended use of the finished loft.
Popular Uses
- An additional bedroom or guest room
- A home office or creative studio
- A bathroom or en-suite bedroom
