Oxford's Trusted Loft Conversion Specialists

A well-built loft conversion is one of the smartest investments you can make in your Oxford home, adding a bedroom, office or living space without touching your garden or footprint.

DKM Builders Oxford Ltd handle everything: structural steelwork, Building Regulations, and the quality finishes that make it feel like it was always there.

Professional Loft Conversions: Design and Construction Services

A loft conversion that stands the test of time starts with the structure, and that's where most problems occur. We handle every technical element in-house, from the first steel beam to the final coat of plaster.

What’s included in every build:

Structural steel beams (RSJs) - sized and installed to spec
Floor reinforcement to Building Regulations
Dormer construction and roof alterations
Compliant staircase design and installation
Fire safety provisions and escape routes
Full insulation and thermal performance upgrades

Every loft conversion we undertake is built to meet current Building Regulations and structural requirements.

Types of Loft Conversions in Oxford

Every roof is different - we build what you need

As experienced loft conversion contractors, we understand that different properties require different structural solutions, layouts, and design approaches. Whether you're looking to maximise head height, create additional bedrooms, or introduce more natural light into your home, we offer a range of loft conversion services tailored to the structure and requirements of your property. Our loft conversion services include:

Dormer Loft Conversions

The most popular choice for Oxford homes. A dormer extends your roofline outward to create full standing height, maximising usable floor space and natural light. Ideal if you want a proper bedroom or home office.

Hip to Gable Loft Conversions

Hip-to-gable loft conversions are the perfect choice for semi-detached and end-of-terrace homes. By rebuilding the sloped hip end as a vertical gable, we maximise the internal space, often the difference between a cramped space and a genuinely liveable room.

Velux Loft Conversions

Where your roof structure already provides adequate height, a Velux conversion delivers a clean, cost-effective result with minimal external alteration. Popular with conservation-area properties.

Each loft conversion is assessed carefully to ensure feasibility, structural stability and compliance.

Fully Managed
In-House Building Services

Most loft conversion problems come down to handover gaps when one trade finishes and another takes over without full context. Because we deliver the structural and internal works with our own team, there are no gaps.

What that means for you:

The same team that installs your steelwork finishes the internal build
You have one point of contact throughout, not five different numbers
Steel is installed to the correct spec, not interpreted by whoever's on site that day
Snagging is caught before it becomes your problem

Where specialist trades such as electricians and plumbers are required, we use approved and trusted subcontractors. As your principal contractor, we ensure all works carried out are to the highest industry standards.

Building Regulations and Sign-Off,
Fully Managed

A loft conversion only adds value to your home if it's fully signed off. We manage every Building Control inspection stage, so you receive a complete compliance package on completion, not a list of issues to resolve.

Covered as standard

Structural engineering calculations and sign-off
Building Regulations compliance at every stage
Fire safety and escape route design
Staircase specification and compliance
Thermal insulation to current standards
Soundproofing between floors

Seamless Integration
with Your Existing Home

The difference between a loft conversion that feels bolted on and one that feels like it was always there is in the details. We match materials, align floor levels, and integrate heating and electrics properly, so the finished space reads as part of your home, not an afterthought.

Floor levels aligned precisely with your existing upper storey
Staircase positioned to complement the layout of your home
External materials matched to your existing roof and brickwork
Plastering and internal finishes to the same standard as the rest of your home
Heating and electrics fully integrated, no surface-run cables or standalone radiators

We Honestly Couldn’t be Happier

DKM Builders have just finished our loft conversion and we honestly couldn’t be happier. From the start, they gave us a clear quote and explained exactly what was included.
