Turn Unused Space Into a Bright, Functional New Room
A loft conversion is one of the smartest ways to increase the space, value and comfort of your Guildford home — without extending your footprint. Whether you want an extra bedroom, a home office, a studio or a multi-purpose family space, our team designs and builds high-quality loft conversions tailored to your property and lifestyle.
We design and build loft conversions across Guildford, handling every stage from initial structural assessment through to finishing and certification. Velux conversions that work within the existing roof shape, rear dormers that dramatically increase the usable floor area and headroom, and hip-to-gable conversions that reclaim the space lost inside sloping side roofs — we build them all and manage every trade involved in delivering a completed room.
With years of experience working on Guildford’s wide mix of properties — from Victorian terraces to modern developments — we ensure your conversion meets planning rules, building regulations and structural requirements.
We work across Guildford and nearby Surrey areas including:
Godalming, Burpham, Shalford, Merrow, Worplesdon, Jacobs Well, West Clandon, Bramley, Onslow Village and surrounding villages.
A Velux conversion is the simplest and most affordable route to converting your loft. The existing roof stays completely unchanged — no dormers, no external alterations — with natural light provided by Velux roof windows fitted into the existing slope. The work involves strengthening the floor to habitable standard, installing insulation throughout, building the staircase, and fitting out the interior with electrics, plastering, and decoration. Velux conversions suit lofts with adequate existing headroom — typically a minimum of 2.2 metres from the ceiling joists to the ridge. Many of Guildford’s detached and larger semi-detached properties across Merrow, Burpham, and the Onslow Village area have roof spaces with sufficient height for this approach. The quickest and most cost-effective conversion type, typically completing in four to six weeks.
A rear dormer extends the roof outward at the back of the property, creating a flat-roofed structure that dramatically increases both usable floor area and standing headroom. Where a Velux conversion confines you to the space under the existing slope with ceiling height tapering toward the eaves, a dormer provides vertical walls and a flat ceiling across the extended section — making the room feel like a genuine additional storey. Full-width rear dormers are the most popular option across Guildford because they transform the entire loft into one spacious room with consistent headroom throughout. Most rear dormers proceed under permitted development without a planning application, though properties within Guildford’s conservation areas — particularly around the town centre, the Mount, and parts of the older residential streets — should confirm the position with Guildford Borough Council before committing to a design.
Many of Guildford’s semi-detached houses — particularly those built from the 1930s through to the 1960s across Park Barn, Stoughton, Bellfields, and Slyfield — feature hipped roofs where the side slopes inward rather than meeting a vertical gable wall. This hip significantly reduces the usable loft space by cutting into the floor area on one side. A hip-to-gable conversion extends the side wall vertically up to the ridge line, replacing the sloping hip with a flat gable end and reclaiming the space that was previously lost. Combined with a rear dormer — the most popular configuration for Guildford’s semi-detached housing — a hip-to-gable conversion creates the most spacious possible loft room. The gable provides full headroom across the width while the dormer extends the depth, delivering a room that genuinely transforms the property.
Most loft conversions across Guildford include an ensuite bathroom or shower room, and the combination of a new bedroom with its own private bathroom is what makes the conversion such a valuable addition — both for daily living and for the property’s market position. The main challenge is routing supply and waste plumbing to the roof space, particularly the soil stack connection for the toilet and shower waste which needs adequate fall to drain properly. We plan every plumbing route during the design stage, confirming waste falls work and the soil connection is achievable before construction starts. We install loft ensuites ranging from compact shower rooms fitted into the eaves to full bathrooms where the room allows, handling all plumbing, tiling, waterproofing, and fitting as part of the conversion programme.
A loft conversion involves structural work that fundamentally changes how your roof supports itself. The steelwork needs specifying correctly for the spans involved, the floor needs strengthening to habitable standard, fire safety provisions must satisfy Building Regulations, and every trade needs coordinating in the right sequence to deliver a finished room. Getting this right requires structural experience, practical knowledge, and the project management to keep the build moving without delays or gaps between trades.
We provide detailed quotes covering every element — structural steelwork, dormer or gable construction, insulation, staircase, electrics, plumbing, plastering, flooring, decoration, and building control fees. You see exactly what’s included and what it costs before work begins. No vague estimates and no surprises during the build.
We carry out loft conversions throughout Guildford and the surrounding Surrey area, covering the town centre, Merrow, Burpham, Onslow Village, Park Barn, Stoughton, Bellfields, Slyfield, Worplesdon, Jacobs Well, Shalford, Chilworth, Bramley, Godalming, Cranleigh, and surrounding villages.

Kitchen & Bathroom Renovations
If you need separate dedicated space rather than additional rooms within the house, a garden room provides it without touching the main building. We build bespoke insulated garden rooms across Guildford with quality cladding, high-specification glazing, built-in heating, and professional electrical installations. Every room is designed for comfortable year-round use. A loft conversion adds internal space upward while a garden room adds separate space outward — some Guildford homeowners combine both, transforming the property from two directions without extending the ground floor footprint at all.
Fast, clear pricing for any attic conversion or loft room project.
