Nailsea is a thriving North Somerset town with a well-established residential community and excellent transport links to Bristol. Much of Nailsea's housing stock was built during the 1960s, 70s and 80s, creating a large number of spacious detached and semi-detached homes with good-sized gardens. Concept Space and Design have completed loft conversions across the town and understand the specific requirements of Nailsea's property types.
Many of Nailsea's post-war homes were built with trussed roofs rather than traditional cut roofs, which means loft conversion requires careful structural assessment and, in many cases, truss cutting and steelwork before conversion can proceed. We carry out this specialist structural work as part of our full design and build service, making loft conversion accessible to Nailsea homeowners regardless of when their property was built.

We carry out the full range of loft conversion types across Nailsea and North Somerset.
A rear dormer is a popular choice for Nailsea's semi-detached homes, creating full head height and a properly usable room. Where the property has an existing cut roof with sufficient ridge height, a dormer can often be completed under permitted development.
Find Out MoreNailsea has a good number of semi-detached properties with hipped roofs where the sloping end limits usable loft space. A hip-to-gable conversion replaces that slope with a vertical wall, opening up significantly more floor area.
Find Out MoreProperties with rear outriggers are well suited to L-shaped loft conversions. This design uses two connected dormers, one on the main rear roof and one extending over the outrigger, to create substantial additional living space with good headroom. L-shaped conversions typically require planning permission, which we manage on your behalf.
Find Out MoreFor Nailsea properties with good existing headroom, a Velux conversion is the most cost-effective route. Roof windows are fitted into the existing slope with no roofline alterations and no planning permission required in most cases.
Find Out MoreMany of Nailsea's 1960s to 1980s homes have trussed roofs. We carry out the specialist truss cutting and steel installation required to open up the loft void, then complete the chosen conversion type on top. It is one of the most common conversion routes we carry out in Nailsea.
Find Out MoreA wrap around conversion combines a rear and hip-end dormer into a continuous structure, ideal for Nailsea's larger semi-detached and detached homes where a single rear dormer alone would leave usable space unreached.
Find Out MoreNailsea is a popular commuter town with strong family demand and good local schools, which means property values are well supported. A loft conversion typically adds 15 to 25% to the value of a Nailsea property. For the town's larger detached and semi-detached homes, adding a bedroom and en-suite in the loft is one of the most cost-effective ways to increase both living space and resale value without the upheaval and cost of moving.
Every loft conversion we complete in Nailsea comes with our 10-year structural guarantee as standard. All work is completed to full building regulations approval, and specialist trades are carried out by our own trusted, long-standing contractors who are fully qualified and Gas Safe registered.
