There are several types of loft conversion available, each suited to different roof types and budgets. The most common types are: Velux/rooflight conversions (the simplest and most cost-effective option), dormer conversions (which add a flat-roofed extension to the rear of the roof), hip-to-gable conversions (which extend the sloping hip of the roof to create a vertical gable), and mansard conversions (which alter the entire roof structure to create a near-vertical rear wall).
Many loft conversions in Cornwall can be carried out under Permitted Development rights, without the need for planning permission. However, there are restrictions on the size and type of loft conversion that can be built under Permitted Development. Loft conversions in conservation areas, AONBs and on listed buildings always require planning permission. We advise all our clients on planning requirements before work starts.
All loft conversions require building regulations approval, regardless of whether planning permission is needed. Building regulations cover structural safety, fire safety (including fire-resistant construction and escape routes), insulation, and staircase design. We manage the building regulations process for all our loft conversion clients.
Loft conversions require careful structural assessment. The existing roof structure may need to be strengthened to support the additional load of the conversion. The floor structure of the loft must be upgraded to support the new use. We always work with structural engineers to design appropriate structural solutions for loft conversions.
Loft conversions offer an excellent opportunity to improve the energy efficiency of your home. We always specify insulation that meets or exceeds current building regulations requirements. Proper insulation will reduce heat loss, lower energy bills and improve comfort in the new loft space.
The staircase to the loft conversion is a critical element of the design. Building regulations require that the staircase meets minimum standards for headroom, width and pitch. The staircase must also be designed to fit within the existing floor plan without compromising the rooms below. We work with our clients to design staircases that are both functional and attractive.
The cost of a loft conversion in Cornwall depends on the type of conversion, the size of the loft, the specification of finishes and the complexity of the structural work. As a rough guide, a basic Velux conversion starts from around £25,000, a dormer conversion from around £35,000, and a full mansard conversion from around £60,000. We provide detailed, transparent quotes for all our loft conversion projects.
