Loft Extension Services in Gosforth

Four distinct extension types to suit every Gosforth property — from cost-effective Velux installations to transformative mansard conversions.

Maximum Space, Minimum Fuss

Dormer Loft Conversions

From £38,000
6–8 weeks

A dormer loft extension is the most popular choice for Gosforth's Edwardian and inter-war properties. By extending the existing roof with a flat-roofed or pitched dormer, we create maximum headroom and usable floor space. Ideal for the classic terraced and semi-detached properties found along Church Road, Elmfield Road, and Kenton Road.

  • Maximum usable floor space and full standing headroom
  • Suitable for most Gosforth Edwardian and inter-war properties
  • Usually no planning permission required (Permitted Development)
  • Creates space for en-suite bedroom, home office, or playroom
  • Adds 20–30% to your Gosforth property value

Transform Your Hipped Roof

Hip-to-Gable Loft Conversions

From £42,000
8–10 weeks

For Gosforth's semi-detached and detached properties with hipped roofs — particularly along Elmfield Road, The Grove, and Moor Road North — a hip-to-gable extension extends the sloping side of your roof to create a vertical gable wall. This dramatically increases the internal floor area.

  • Dramatically increases usable loft space
  • Perfect for semi-detached homes in Gosforth
  • Often combined with a rear dormer for maximum space
  • Creates a room large enough for a master suite
  • Significantly enhances kerb appeal and property value

Velux / Rooflight Loft Conversions

From £22,000
3–4 weeks

The most affordable and least disruptive extension option. We install premium Velux roof windows into your existing roof structure without altering the roofline. Perfect for properties with adequate existing headroom or where planning constraints limit external alterations — particularly suitable for Gosforth's 1930s semis with generous existing roof voids.

  • Most cost-effective conversion option
  • Fastest build time — typically 3–4 weeks
  • No change to external roofline
  • Ideal for conservation area properties
  • Floods your loft with natural light

The Ultimate Transformation

Mansard Loft Conversions

From £55,000
10–12 weeks

A mansard extension replaces one or both roof slopes with a near-vertical wall and a flat roof on top — effectively creating an entire new floor. While this typically requires full planning permission, the result is extraordinary. For premium Gosforth properties on roads like The Grove and Kenton Road, a mansard creates unparalleled living space.

  • Creates a full additional floor of living space
  • Maximum headroom across the entire footprint
  • Can include Juliet balconies for panoramic views
  • Highest return on investment for larger properties
  • Architectural statement that enhances the streetscape
