Dormer Loft Conversion Long Eaton
A dormer loft conversion is the most popular way to add a proper bedroom and bathroom to homes in Long Eaton. By building a box-shaped extension out from the rear roof slope, we create full head height and usable floor space in lofts that would otherwise feel cramped.
We have converted lofts across Long Eaton, from Victorian terraces near the town centre to 1930s semis around Sawley Road and newer homes towards Chilwell. Every project starts with a free survey so you know exactly what your roof can take.
- Free loft survey and head-height check at your Long Eaton home
- Full design, structural calculations and Building Regs handled
- Most dormers built under permitted development – no planning stress
Why Dormers Suit Long Eaton Homes
Much of Long Eaton’s housing stock – the terraces off Tamworth Road, the semis around College Street and the estates near Wilsthorpe – has pitched roofs with limited head height at the eaves. A rear dormer solves this. It squares off part of the roof, giving you flat ceilings, standing room across most of the new floor, and space for a full staircase.
A typical dormer conversion here adds a double bedroom with an en-suite, which is one of the most cost-effective ways to add value in NG10. Because Long Eaton sits close to Nottingham, Derby and the M1, family homes with an extra bedroom are in steady demand, and a well-built loft conversion usually pays for itself at resale.
We manage the whole job: measured survey, drawings, structural calculations, Building Regulations sign-off with Erewash Borough Council, and the build itself. Most dormers are built through the roof, so disruption inside your home is kept to the final couple of weeks.
Best For
Terraces and semis in Long Eaton with 2.2m or more at the ridge, homeowners who want a full bedroom and bathroom rather than just a hobby room, and growing families who would rather convert than move.

Planning Rules for Dormers in Long Eaton
📋 What You Need to Know
Most rear dormers in Long Eaton can be built under permitted development, which means no planning application. The key limits are: up to 50 cubic metres of added roof space for semis and detached homes (40 for terraces), the dormer must sit below the ridge line, be set back from the eaves, and use materials that match the existing house. Dormers on the front roof slope facing the road normally do need planning permission from Erewash Borough Council. If your permitted development rights have been removed or you live in a flat, a full application is required. We check all of this at survey stage and handle any paperwork, including the Lawful Development Certificate we recommend for every project.

Dormer Loft Conversions We Have Built
What Long Eaton Homeowners Say
“Our terrace off Tamworth Road now has a lovely double bedroom and shower room in the loft. The team confirmed it was permitted development, sorted all the Building Regs and finished in seven weeks. Couldn’t fault them.”
“We nearly moved house before getting a quote for a dormer. Best decision we made – our 1930s semi near Wilsthorpe gained a fourth bedroom for far less than the cost of moving. Tidy workers and clear communication throughout.”
“From the free survey to the final inspection everything ran to plan. Most of the work was done from the scaffold so we lived at home the whole time. The dormer looks like it has always been part of the house.”
Dormer Loft Conversion Questions – Long Eaton

Front-facing dormers normally need planning permission from Erewash Borough Council. We check your property at the free survey and handle any applications for you.
Most dormer conversions in Long Eaton come in between 42,000 and 65,000 GBP fully finished, depending on the size of the dormer and whether you add an en-suite. Larger L-shaped dormers cost more. Every quote follows a free measured survey, so the figure you get is fixed and written.
If you have around 2.2m from the loft floor to the ridge, a dormer will normally work. Most terraces and semis in Long Eaton meet this. Lower roofs sometimes still work with a different design. Our free survey confirms it either way before you spend a penny.

Yes, in most cases. Adding a bedroom and bathroom typically lifts the value of an NG10 property by 15-20%, and demand for larger family homes in Long Eaton is steady thanks to its links to Nottingham, Derby and the M1. A signed-off, Building Regs-compliant conversion also reassures future buyers.
