LOFT DESIGNS AND STYLES

Choose your ideal loft design

There are several ways to convert your loft, each suited to different property types and space requirements. Here are the most common options for London homes, along with their key benefits.

Dormer loft conversion

The most popular choice for London homes. Creates maximum usable floor space with full head height. Perfect for bedrooms, home offices, or bathrooms. Often falls within permitted development rights.


Ideal for: Terraced and semi-detached houses needing extra bedrooms or workspace.

Mansard loft conversion

Maximises space with a near-vertical wall and flat roof. Creates the most internal volume of any conversion type. Excellent for multiple rooms or open-plan spaces.


Ideal for: Properties needing maximum space or multiple rooms in the loft.

Hip-to-gable loft conversion

Extends the sloped roof to create a vertical wall. Particularly effective for end-of-terrace or semi-detached homes. Can be combined with a dormer for optimal space.


Ideal for: Semi-detached and end-of-terrace houses with hipped roofs.

PLANNING AND REGULATIONS

Planning made simple

Getting your loft conversion approved requires careful navigation of local planning rules and building regulations. We manage the entire process, ensuring compliance at every step.

Permitted Development

Most loft conversions in London fall under permitted development rights. No full planning permission needed if your design meets standard criteria.


Planning Permission

Required for larger conversions or homes in conservation areas. We handle the entire application process and liaise with your local council.


Building Regulations

All loft conversions need building regulation approval. Our drawings and calculations ensure compliance from the start.


Local Council Requirements

We work with all London boroughs and know their specific requirements. Your application is optimised for your local authority's policies.
