The unused roof space above your ceiling is one of the most valuable parts of your home — and in most Harlow properties it’s doing nothing more productive than storing luggage and boxes of things you’ve forgotten you own. A loft conversion transforms that wasted void into a genuine additional floor, adding a bedroom, bathroom, home office, or whatever room your household needs most, without building outward, losing garden, or navigating the expense of a ground floor extension.
We design and build loft conversions across Harlow, 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.
Our service covers the complete project. We coordinate structural steelwork, floor strengthening, dormer or gable construction, insulation, staircase installation, electrics, plumbing for ensuites and bathrooms, plastering, flooring, and decoration. You deal with one team from the first steel beam to the final coat of paint, with clear communication and transparent pricing throughout.

A Velux conversion is the most straightforward and affordable route to converting your loft. The existing roof stays 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 Harlow’s detached properties across Old Harlow and the larger housing in Church Langley and Newhall have roof spaces with sufficient height for this approach. The quickest and most affordable conversion type available.
A rear dormer extends the roof outward at the back of the property, creating a flat-roofed structure that dramatically increases both the usable floor area and the standing headroom. Where a Velux conversion confines you to the space under the existing slope, a dormer provides vertical walls and a flat ceiling across the extended section, making the room feel like a proper additional storey rather than a converted attic with limited headroom. Full-width rear dormers are the most popular option across Harlow 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, keeping the process straightforward and the timeline shorter than projects requiring formal planning approval from Harlow District Council.
Many of Harlow’s semi-detached houses — particularly across the original new town estates in Staple Tye, Great Parndon, Potter Street, and Mark Hall — 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 Harlow’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.
Most loft conversions across Harlow include an ensuite bathroom or shower room, and the combination of an additional bedroom with its own private bathroom is what makes the conversion such a valuable addition to the property. The main challenge is routing supply and waste plumbing to the roof space — particularly the soil stack connection that handles toilet and shower waste. We plan the plumbing routing during the design stage, ensuring waste falls are adequate and the soil connection is achievable without compromising the rooms below. We install loft ensuites ranging from compact shower rooms fitted into the eaves space 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, the floor needs strengthening to habitable standard, fire safety provisions must meet Building Regulations, and every trade needs coordinating in the right sequence to deliver a finished room rather than a half-completed project. Getting this right demands experience, structural understanding, and the project management to keep everything moving without gaps or delays.
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 Harlow and the surrounding Essex and Hertfordshire area, covering Old Harlow, Staple Tye, Great Parndon, Potter Street, Mark Hall, Latton Bush, Church Langley, Newhall, Kingsmoor, Epping, Sawbridgeworth, Bishops Stortford, and surrounding towns and villages.
Garden rooms are one of the most flexible and cost-effective ways to add usable space to your home without altering the main building. At Harlow Builders, we design and build fully insulated garden rooms that are comfortable, practical and suitable for use all year round.
Our garden rooms are built using modern construction methods, with insulated walls, floors and roofs to ensure consistent internal temperatures. Each project is tailored to the size of your garden, the intended use of the space and the overall style of your property.
If you’re converting the loft and the kitchen or bathroom needs attention too, having one team manage both makes practical and financial sense. We carry out complete kitchen and bathroom renovations across Harlow, handling strip-out, structural modifications, plumbing, electrics, tiling, flooring, and expert fitting. We install kitchens from any supplier and coordinate all trades in sequence. The electrician and plumber already on site for the loft conversion move seamlessly into the kitchen or bathroom work without scheduling gaps or coordination problems between separate contractors.
