Loft Conversions Hull
Create Space Without Moving House
Service Overview
A loft conversion is one of the most cost-effective ways to add a bedroom, home office, or bathroom to your Hull property without the upheaval of moving or the expense of a ground-floor extension. BuildFastHullLimited has completed loft conversions across Hull's housing stock, from Victorian terraces in HU3 to detached family homes in HU10, and we manage the full project from structural design through to final finish.
Types of Loft Conversion We Carry Out in Hull
Velux / Rooflight Loft Conversion
The most straightforward and affordable type of loft conversion, involving no changes to the existing roof structure. We install Velux or equivalent roof windows to bring in natural light and headroom. Ideal for properties with good existing head height, typically 2.2 metres minimum from floor to ridge.
Best for: Creating a bedroom or office without altering the roofline. No planning permission required in most cases.
Dormer Loft Conversion Hull
The most popular conversion type for Hull’s semi-detached and terraced properties. A dormer extends the rear roof slope outward to create a flat-roofed extension that significantly increases both floor area and usable headroom. The result is a full-height room with proper windows rather than a restricted attic feel.
Best for: Properties where a Velux conversion would leave insufficient standing room. Usually falls within Permitted Development on the rear elevation.
Hip-to-Gable Conversion
Common on detached and semi-detached properties in Hull’s suburban areas, HU10, HU13, HU14, where the hipped roof slopes down at the sides. We extend the side slope to create a vertical gable wall, dramatically increasing the internal volume of the converted space.
Best for: Larger properties where maximum loft space is the priority. Often combined with a rear dormer.
Mansard Loft Conversion
A more extensive conversion where the entire rear roof slope is rebuilt at a steeper angle, typically 72 degrees, with a flat roof at the top. Provides the maximum floor area and full ceiling height across the width of the property. Mansard conversions require planning permission and are more common in Hull’s period terraces.
Best for: Maximum space creation. Commonly used in Hull’s Victorian and Edwardian terraces.

Frequently Asked Questions
Most dormer and Velux conversions on the rear of properties fall within Permitted Development Rights and do not require planning permission. Hip-to-gable and mansard conversions, and any conversion on a property in a conservation area, typically do require permission. We advise on this as part of our free initial assessment.
A standard dormer conversion in Hull takes 6–10 weeks from start of works. More complex conversions, or those involving planning permission, will take longer. We provide a clear programme of works before starting.
Yes. A bedroom and bathroom loft conversion typically adds 15–20% to a property's value. Given Hull's average house prices, that often represents a return significantly above the conversion cost.
Most lofts in Hull can be converted. Key factors are roof pitch (ideally 30 degrees or more), head height, and the condition of existing joists. Our free site assessment will confirm viability before you commit to anything.
