Get In Touch

Unlock the full potential of your loft with a high-quality hip to gable loft conversion from LXR Construction. We specialise in this popular structural upgrade across London, helping homeowners transform cramped, angled lofts into spacious, full-height rooms. Whether you want a new master bedroom, office, ensuite bathroom or an entirely new upper floor, we handle everything — from design and planning to structural engineering and final fit-out.

Why Choose a Wrap Around Extension?

  • Transform Your Loft Into a Full-Height, Usable Space – A hip to gable conversion replaces the sloping side (hip) of your roof with a vertical wall (gable), dramatically increasing headroom and usable floor area — perfect for creating functional rooms.
  • Ideal for Semi-Detached, End-Terrace & Detached Homes -Because these properties have a sloping hip roof, they benefit hugely from converting it into a gable end, unlocking space that would otherwise be wasted.
  • Seamlessly Blend With Existing Architecture – A hip to gable conversion extends your home’s profile in a natural, visually appealing way, maintaining architectural balance and improving kerb appeal.
  • Enhanced Property Value – Hip to gable conversions add substantial usable space, often increasing home value by 15–25%, depending on layout and chosen finish.

Our Step-By-Step Process to Building Your Hip to Gable Loft Conversion

1

Consultation & Design

We begin by assessing your roof structure, space potential and how you plan to use your new loft area. Our designers explore staircase placement, gable construction, dormer additions, Velux window options and optimised room layouts. We then create a bespoke design that maximises space, natural light and practicality.

2

Planning & Approvals

Hip to gable loft conversions often fall under permitted development, but larger structural changes or dormer additions may require planning permission. We manage everything — architectural drawings, planning submissions, structural engineering, party wall notices and full building regulations compliance.

3

Construction & Project Management

Our experienced loft conversion team handles all structural and interior works with precision. A dedicated project manager oversees the hip-to-gable rebuild, steel installation, roofing, insulation, windows, electrics, plumbing and plastering. You receive regular updates throughout the project for complete peace of mind.

4

Completion & Interior Fit-Out

Once the construction is complete, we finish your new space with flooring, lighting, custom joinery, bathrooms (if included), heating and full decoration. We then perform a comprehensive quality inspection and walk you through your new loft conversion to ensure every detail meets our standards.

How Much Does a Hip to Gable Loft Conversion Cost?

Pricing varies depending on roof structure, size, glazing, and internal finishes. Typical costs include:
