Looking for a loft conversion in Leigh on Sea? Our team at Fox Conversions specialises in creating bright, practical loft spaces that add real value to homes across SS9. Whether you live near Leigh Broadway, Chalkwell, or further into town, we’ve helped many local families transform unused lofts into modern bedrooms, offices and en-suites. With over 12 years of experience, we handle everything in-house—from planning and structural work to bathrooms and finishes—so your loft conversion in Leigh-on-Sea is stress-free from start to finish.
Many Leigh-on-Sea homes — from Victorian terraces to hipped bungalows near Belfairs — have lofts with huge untapped potential. As a small, owner-led company, we take care of the whole job personally: dormers, Velux rooflights, and full hip-to-gables, all designed to suit the property and the family living in it.
Some clients want a master suite with estuary views, others a quiet office or extra bedroom. Whatever the goal, we design and build conversions that fit your budget and flow naturally with the rest of your home. With our local knowledge and hands-on approach, you don’t just get more space — you get a home that works better for the way you live.
Not sure what type of loft conversion will work best for your property? Book a free survey and we’ll talk you through whether a loft conversion in Leigh-on-Sea is best done as a dormer, hip-to-gable or simple Velux.
The owners of this 1930s semi on Darneth Road had lived there for years but had outgrown the space. They wanted a proper master suite upstairs with estuary views, but moving wasn’t on the cards. The loft had the height, so a hip-to-gable with a rear dormer was the right answer.
What we did
The existing roof was over 40 years old with handmade clay tiles that were long past their best. We stripped it back completely and re-roofed in new Marley cambered clay tiles with fresh Code 4 leadwork. To carry the new floor, we installed 203x133 UB steels with spliced connections – the only way to get them in given the site access.Once the shell was watertight, we laid PIR insulation to meet current regs, formed stud walls, and built the new staircase neatly over the existing landing to keep headroom. Oak joinery was used on the doors and stairs to match the rest of the house.
The result
The Darneth Road project shows how a hip-to-gable loft conversion Leigh on Sea can create over 27m² of new living space, including a full master suite with estuary views. At the front, a 17.8 m² master bedroom with Velux roof windows looking out towards the Thames estuary. At the back, a 6.2 m² bathroom with a freestanding bath, double shower tray and twin basins. Off to the side, a 3.1 m² walk-in wardrobe.The conversion gave the clients everything they wanted – more room, proper storage, a luxury bathroom, and views they’d never had before. Instead of moving, they’ve now got a home that works for them long-term and adds serious value if they ever do decide to sell
This project shows how a hip-to-gable loft conversion can unlock both space and lifestyle benefits in Leigh-on-Sea homes. Learn more about our Dormer Loft Conversions and Hip-to-Gable Conversions across Essex.
Fox Conversions have recently completed my loft conversion, costs were as stated in the original quote and I requested extra work to be included which was all costed very reasonably. Nothing was too much trouble. The outcome is superb, I couldn't have wished for better results. The price quoted was better than other loft conversion companies that I received quotes from and the stage payment process is also very reassuring. This gave me peace of mind as there were no huge upfront payments. I have no hesitation in recommending Chris and his team.
Client Review - Checkatrade
Perfect for 1930s semis and terraces around Chalkwell and Leigh Broadway. By building a rear dormer, we create full headroom across most of the new floor. Clients often use this setup for a proper master bedroom with en-suite. We tile dormers in Marley or Redland tiles to match the existing roof and use Code 4 leadwork, so it blends in while giving you the extra space.
Bungalows and hipped semis near Belfairs and Marine Estate usually lose space to sloping side roofs. Converting the hip into a gable unlocks a much bigger loft, often enough for an entire upstairs suite. We’ve built these in SS9 where families wanted a full master and bathroom without moving house.
If your roof already has good ridge height — common in Leigh terraces close to the estuary — a Velux conversion is the fastest, least disruptive option. We fit roof windows straight into the slope, creating a bright guest bedroom, office, or playroom with plenty of natural light and minimal exterior change.
Mansard Conversions
Less common locally, but a good option for period cottages near Leigh Old Town. A mansard alters the rear roof angle to maximise usable floorspace. They’re ideal if you want modern open rooms inside but still keep the traditional street-facing look.
At Fox Conversions, we follow a proven step-by-step process to make your loft conversion in Leigh-on-Sea smooth and stress-free:
Most lofts here fall under permitted development, so you usually won’t need full planning. Exceptions can be homes near Marine Parade or in conservation areas. We’ll check that for you at survey and, if drawings or a submission are needed, we’ll take care of it.
Every roof is different. As a guide, Velux-only jobs often start in the mid £30k range, while a dormer on a 1930s semi in Chalkwell or Leigh Broadway tends to come out mid-range. A full hip-to-gable on a bungalow in SS9 will be higher. We give you a clear, itemised quote so you know exactly what’s included.
On average 8–10 weeks, depending on weather and access. A Velux job can be watertight in 3–4 weeks. A bigger hip-to-gable with a dormer usually takes a couple of months. We give you a programme up front so you know when each stage is due — steels, stairs, plaster, second fix.
Yes. Most of our work is Leigh-on-Sea and Southend, but we cover the whole of Essex — Brentwood, Romford, Upminster, Rayleigh, Billericay.
We’re not general builders who turn their hand to lofts. We only do lofts, garages and extensions. That means we know the structures inside out, and you deal directly with me, not a sales rep. We run clean, respectful sites, keep you updated, and take payment in fixed stages — no big upfront deposits.
Rule of thumb: if you can reach up and touch the ridge easily, it may be too low. You generally want around 2.3–2.4m of head height at the ridge. We’ll measure it properly at survey and let you know if you’re in the clear or if a roof lift is needed.
Most of our Leigh clients add a new bedroom and en-suite, but we’ve done home offices overlooking the estuary, kids’ playrooms and even a walk-in wardrobe. It depends what your house needs most.
All conversions need building control approval. That means insulation to current U-values, fire doors and smoke alarms, proper structural steels and joists, safe stair design. We supply full drawings and arrange inspections so you’ve got the paperwork for resale.
Every property is different, but almost every attic has hidden potential. By reconfiguring the structure and layout, we turn unused loft space into practical rooms that flow naturally with the rest of your house. From stairs placement to clever storage, our designs make the most of every inch.
Your roof type is one of the biggest factors in choosing the right conversion. Terraced houses often suit rear dormers, while bungalows benefit from hip-to-gable builds. We work with high-quality roofing materials and leadwork to ensure your new loft is watertight, durable, and blends with the rest of your home.
Adding a loft conversion doesn’t just create more square metres — it changes how you live in your house. Many Leigh-on-Sea families gain a full master suite, freeing up rooms downstairs for growing children or home offices. The result is a home that works better for modern living, without the stress of moving.
