Types of Loft Conversions We Offer in Oxford

Dorma Loft Conversion

A popular choice for adding maximum headroom and floor space. This extension projects vertically from the roof, creating a full-height room that feels like a natural part of the home.

Velux (Rooflight) Loft Conversion

The simplest and most cost-effective option, using skylights within the existing roof structure. Ideal if you want more light and usable space without major alterations.

Hip-to-Gable Loft Conversion

Perfect for semi-detached or end-of-terrace homes with sloping roofs. This method straightens the roof’s side slope to create more internal space and a traditional room layout.

Mansard Loft Conversion

This involves raising the party wall and replacing the sloping roof with a near-vertical one. It creates the most internal space, ideal for larger, high-end conversions.

Frequently Asked Questions about Loft Conversions.

Here are some common questions about Loft Conversions in Oxford.

How long does a loft conversion take to complete?

The average loft conversion takes between 4 to 8 weeks, depending on the size, type, and any structural work involved. We provide a clear project timeline before we begin, and our experienced team works efficiently to deliver on time, without compromising quality.

Do I need planning permission for a loft conversion?

In most cases, no. Many loft conversions fall under what's called permitted development rights, meaning you won’t need formal planning permission as long as your project meets certain conditions. However, there are exceptions, especially in conservation areas or if you're making significant alterations to the roofline. We’d be happy to assess your home and advise exactly what’s needed to keep things compliant and on track.

How much value will a Loft Conversion add to my home?

Absolutely. Loft conversions are one of the best ways to increase your home’s value. A well-executed conversion can add up to 20% to your property’s market price, especially if it creates an additional bedroom and bathroom. It’s a strong investment that combines practical space with long-term financial return.

How much does a Loft Conversion cost in Oxford?

Costs typically range from £25,000 to £65,000, depending on the type of conversion, finishes, and any structural changes required. We offer detailed, transparent quotes and will walk you through all options to match your budget and vision—without any hidden extras.

So a 20m² extension might cost £36k–£70k+. This excludes design fees, and possible planning costs. A clear, itemised quote from your builder is essential.

Our team at Kingdom Design & Build offers transparent quotes and can help optimise your budget without compromising on quality.

Do I need an architect or structural engineer for a Loft Conversion?

In most cases, yes, you’ll need input from both. An architect helps design a layout that maximises space, light, and usability, ensuring the new room blends seamlessly with the rest of your home. A structural engineer is essential for calculating load-bearing requirements and ensuring that any structural changes, like steel beams or altered rooflines, meet safety standards. At Kingdom, we handle this for you by working with trusted professionals to ensure every detail is designed and built to spec, safely and in compliance with Building Regulations.

Will I need to move out during the work on a Loft Conversion?

In most cases, you won’t need to move out. We’ll communicate clearly throughout the project and do everything we can to ensure you remain comfortable in your home.

Do you offer a warranty on your work?

Yes, all of our work is backed by a workmanship guarantee, ensuring quality and durability. We also ensure that all work meets current building regulations.
