Hip to Gable Loft Conversion Plans

Maximise Loft Space from Just £1,195 + VAT

If your home has a hipped roof, you may be missing out on valuable space. A hip to gable loft conversion is one of the most effective ways to unlock that potential by transforming a sloped side roof into a full-height gable wall — creating more headroom, floor space, and design flexibility.

At Draw Plans, we specialise in creating high-quality, fixed-price hip to gable loft conversion plans from just £1,195 + VAT. Whether you're based in London, Essex, Kent, Surrey, Hertfordshire or nearby, our expert team will deliver architectural plans ready for planning approval and Building Control.

What Is a Hip to Gable Loft Conversion?

Homes with hipped roofs (often semi-detached, end-of-terrace, or detached) have sloped sides that reduce the usable loft area. A hip to gable conversion rebuilds this sloping section to form a vertical gable wall, creating significantly more usable internal space.

Often combined with a rear dormer, this type of loft conversion is ideal for creating:

A large master bedroom
A home office with full ceiling height
An en-suite or walk-in wardrobe
Even a small studio or separate living area

Benefits of a Hip to Gable Loft Conversion

A hip roof loft conversion offers some of the greatest space gains for homes with angled side roofs. Here’s why homeowners love them:

Maximises head height and internal space
Transforms your loft into a full-width, functional room
Ideal for homes with limited loft space
Can often be completed under permitted development
Boosts property value by 15–20%
Improves natural light and ventilation

If you’ve been looking into loft conversion ideas for hipped roofs, this design should be top of your list.

Design & Layout Tips for Hip to Gable Conversions

Making the most of your new space requires a smart layout. Here are some expert design tips:

Floor Plan Ideas:

Position the stairs directly above your existing staircase to optimise circulation
Place the bedroom or main living area under the newly created gable section
Use rear dormers to fit a spacious en-suite bathroom or walk-in wardrobe
Create built-in storage along the eaves for a clutter-free design

Light & Ventilation:

Add large Velux roof windows to bring in daylight
Consider a Juliet balcony or gable-end window for views and ventilation

Integration Tips:

Match external materials with the original house for seamless aesthetics
Use matching flooring and finishes to make the loft feel like part of the home
Connect services (plumbing, heating, electrics) efficiently by positioning bathrooms near existing pipework

Planning Permission for Hip to Gable Loft Conversions

Many hip to gable loft conversions fall under permitted development rights, provided they meet the following:

Do not exceed 50m³ of additional roof space (40m³ for terraces)
Do not exceed the height of the existing roof
Use materials similar in appearance to the original house
Do not include a balcony, veranda, or platform

If you live in a conservation area or your property is listed, planning permission is likely required — but don’t worry, we handle the application process from start to finish.
