Planning a Loft Conversion?

For a typical loft conversion, we prepare the planning drawings needed to explain the proposal clearly, including existing and proposed floor plans, roof plans, elevations and relevant sections. We also manage the appropriate planning application for straightforward projects.

The example on this page shows a hip-to-gable alteration and rear dormer, with a new loft floor, staircase, bathroom arrangement and rooflights.

Do I Need Planning Permission for a Loft Conversion?

Some roof alterations fall within permitted-development rights, while others need planning permission. The design, property type, location, previous roof additions and any restrictions must be considered together.

Loft Conversion Permitted Development

Permitted development can cover certain loft conversions if all limitations and conditions are met, including roof-volume allowances, height, position, materials and window requirements. Designated land and Article 4 Directions may restrict these rights.

Dormer Loft Conversions

A dormer projects from the roof slope to create additional internal headroom and floor space. Its size, position and appearance influence the correct planning route.

Hip-to-Gable Loft Conversions

A hip-to-gable alteration changes a sloping side roof into a vertical gable wall. It can increase usable roof space, but eligibility depends on the house and the applicable planning rules.

Loft Conversion FAQs

Does a loft conversion need planning permission?

Some loft conversions can be permitted development, while others need planning permission. The roof alterations, property and local restrictions all matter.

Can a dormer be permitted development?

Some rear dormers can qualify if all relevant volume, height, position, materials and other conditions are met.

Can a hip-to-gable conversion be permitted development?

It may qualify on some houses within the overall roof-volume allowance, but property type, location and previous roof additions must be checked.

Are rooflights included in the drawings?

Where rooflights form part of the agreed proposal, their position is shown on the relevant roof plans, elevations and sections.

What happens after planning?

Building Regulations information and structural calculations may then be required. These are separate from the £695 planning service.
