Why Attic Conversion Oxford

A better room upstairs, without the compromise.

Head height, rafter type, chimney positions, party walls and the route for the stairs all shape what is possible. We begin with those practical questions, then design a room around them.

From a compact rooflight conversion to a full mansard, we compare the realistic options for your property rather than steering every enquiry towards the same product.

The details that matter

Decided early, not on site.

The approach

Local knowledge. Considered construction.

Oxford roofs, streets and planning contexts are not interchangeable. We work across the city and surrounding towns, with the property and its setting in mind.

One accountable team

Survey, design, approvals and build coordinated under one roof.

Clear written scope

Assumptions, exclusions, programme and payment stages agreed upfront.

Architecturally accurate

Each conversion route is matched to the roof shape and property.

Local aftercare

A nearby team to speak to long after the scaffolding comes down.

How we work

A clear process. No guesswork.

From the first survey to the final handover, every stage is owned, sequenced and explained.

01

First conversation

Tell us about the house, the space you need and any constraints you already know about.

02

Survey & feasibility

We measure the roof, check access and explain which routes are realistic for the property.

03

Design & quotation

The scope, specification, assumptions, exclusions and payment stages are set out in writing.

04

Approvals & programme

Planning, structural design, party wall and Building Regulations requirements are coordinated.

05

Build & handover

The work is sequenced carefully, inspected at the right stages and explained at completion.

Budget with confidence

A useful budget starts with an honest range.

Velux / rooflight

£25,000 – £40,000

£35,000 – £55,000

6–8 weeks on site

A practical way to create usable floor area and vertical headroom.

Mansard / L-shaped

£50,000 – £80,000

8–12 weeks on site

Larger structural changes for more generous suites and ensuite space.

Broad planning guides only, not quotations. Final costs depend on the property, structure, access, specification and approvals. A survey and written scope are needed before a reliable price can be given.

Questions

The practical answers, before you commit.

Every property is different, but these are the points worth understanding before a project begins.

How much does a loft conversion or extension cost?

The price depends on size, structure, access, materials, finishes, design and permissions. Request a written, property-specific quotation.

Do I need planning permission?

Some work may fall under permitted development, while other projects need planning permission. Your design and property should be checked before construction.

How long does the work take?

Time varies by project scope, approvals, weather, access and finishes. A realistic programme can be discussed after the survey.

Can you work on older or unusual Oxford properties?

Yes, suitable projects can be assessed individually. Older homes may need extra attention to structure, materials, access and local planning requirements.

Can you build a conversion with a trussed roof?

A trussed roof may be convertible, but structural changes must be assessed and designed correctly before work begins.

How do I book a consultation?

Call or complete the enquiry form. Share your location, project ideas and preferred contact time.
