Most Popular in Cramlington

Dormer Loft Conversions

From £28,000
6–8 weeks

A rear dormer is the most popular choice for Cramlington's new-build semis and is what most people mean when they say "loft conversion". We extend the rear slope of your roof outward to create a full-height room — a proper bedroom, home office, or living space. Most Cramlington properties qualify for Permitted Development so there's no planning hassle, and the work is done in around 6–8 weeks.

  • Full standing headroom and maximum usable floor space
  • Works on most Cramlington new-build semis
  • Usually no planning permission needed (Permitted Development)
  • Creates a proper bedroom, home office, or playroom
  • Adds value — typically 15–20% on Cramlington properties

For Semi-Detached Homes

Hip-to-Gable Loft Conversions

From £34,000
8–10 weeks

If you have a semi-detached property in Cramlington, there's a good chance it has a hipped roof — the sloping triangular section on the side. A hip-to-gable conversion replaces that slope with a vertical wall, opening up far more internal space than a standard dormer alone. Often combined with a rear dormer for the maximum result.

  • Dramatically more internal space than a standard dormer
  • Ideal for Cramlington semis and end-terraces
  • Often combined with a rear dormer for maximum space
  • Can comfortably fit a master bedroom and en-suite
  • Good return on investment on NE23 properties

Velux / Rooflight Conversions

From £18,000
3–4 weeks

If your budget is tight or you already have decent headroom up there, a Velux conversion is the smart choice. We install quality roof windows into your existing roof structure without touching the roofline. It's the quickest, most affordable way to turn a dusty loft into a usable room. Great for a home office, guest room, or kids' space on a realistic budget.

  • Most affordable conversion option — from £18,000
  • Fastest build time — typically 3–4 weeks
  • No change to external roofline
  • Ideal if your loft already has reasonable headroom
  • Fills the space with natural light

Mansard Loft Conversions

From £45,000
10–12 weeks

A mansard conversion replaces the roof slope with near-vertical walls and a flat roof — effectively adding an entire new floor. It's the biggest and most expensive option, and it does require full planning permission. But if you have a larger property in Heaton and want to maximise space, it's hard to beat. We manage the planning application as part of the job.

  • Creates the maximum possible additional living space
  • Full headroom across the entire floor area
  • Can include Juliet balconies
  • Best long-term investment for larger Heaton properties
  • We handle planning permission from start to finish
