A loft conversion buys a bedroom and a bathroom without losing a metre of garden, and in most cases without a full planning application. Whether it works at all comes down to three things: head height, roof pitch and what the existing structure will carry. Those answers shape the design before taste gets a say.

We check the roof before we draw it. Where a dormer or a hip to gable is needed to make the space usable, it is designed to sit properly on the house rather than look like something added afterwards. Planning, structure, fire safety and Building Regulations are handled by the same team, so the conversion stays with one team.

Loft Conversions

WHAT WE OFFER?

Every service below states what the work covers and what you receive at the end of it.

01

FEASIBILITY AND HEAD HEIGHT SURVEY

The first question is whether the loft converts at all. We measure head height, pitch and structure before you commit to anything.

You receiveA written view on whether it converts, what shape it would take and what it will not give you.
02

PERMITTED DEVELOPMENT AND CERTIFICATES

Many houses can extend into the roof under permitted development, within volume limits that depend on the type of house and are easy to breach without noticing.

You receiveConfirmation of what can be built without a full application, and an application for a certificate of lawfulness where it helps.

03

DORMER, HIP TO GABLE AND ROOFLIGHT DESIGN

The roof alteration is what makes the space usable and what the street sees. It is drawn against the existing roofline and the neighbouring houses.

You receiveThe drawings for the conversion and the roof alterations it needs.
04

STRUCTURE, STAIRS AND FIRE ESCAPE

A loft floor was never designed to be lived on, and the new stair has to come out of a room below.

You receiveStructural calculations, the new floor design, and a stair and escape route designed to Building Regulations.
