Timber Frame Construction in Cambridgeshire
Timber Frame Extensions, Self-Build Projects and Structural Timber Construction

KMP Carpentry and Joinery provides timber frame construction across Cambridgeshire for homeowners, self-builders, developers and contractors. We design, build and install timber structures for extensions, self-build homes, outbuildings and larger developments. So, whether you need an experienced timber frame installer or a team to manage the full project, we are here to help.
Many clients want more than just a contractor to erect a frame. They want a team that can plan, coordinate and deliver the whole project. As a result, we often act as main contractor in Cambridgeshire, giving clients a single point of contact throughout the build.
Timber Frame Construction Services
We offer a wide range of timber construction services across Cambridgeshire. Every project is tailored to your requirements, whether you are planning a home extension, a self-build or a larger development.
Our services include timber frame extensions, self-build timber frame projects, timber outbuildings and garden rooms, structural timber framing, oak-framed structures and major refurbishments and structural alterations.
Our approach stays the same on every project. We focus on quality workmanship, careful planning and reliable delivery from start to finish.
Timber Frame Extensions
A timber frame extension can add valuable living space while keeping the character of an existing property. We build timber frame extensions for homeowners, developers and property investors across Cambridgeshire.
So, whether you are planning a single-storey extension, rear extension or larger open-plan addition, we work closely with architects, engineers and other trades. As a result, clients benefit from a durable structure that performs well for years to come.
You can view our recent rear extension project in March, Cambridgeshire to see how we manage structural timber builds alongside interior fit-outs and final finishes. If you are still exploring your options, read our Timber Frame Extension Guide to learn what happens from the first planning stages through to construction and completion. It explains the process, what to consider before you start and what you can expect during a typical timber frame extension project.

Self Build Timber Frame Projects
Building your own home is a big undertaking. However, the right team makes the process far more straightforward.
We work with self-build clients throughout Cambridgeshire. Our work includes timber frame shell construction, structural timber installation and frame erection. We also provide practical support throughout the build process. Whether you have approved drawings in place or are still developing your plans, we can help deliver the structural timber elements of your project with confidence.

Timber Outbuildings and Garden Rooms
We design and build bespoke timber outbuildings across Cambridgeshire for year-round use. Popular projects include garden rooms, home offices, workshops, garden bars, timber garages, storage buildings and outdoor entertainment spaces
Every structure is designed around the specific requirements of the project rather than working from a standard template. So, clients get a building that suits both the site and how it will be used. We apply the same construction principles used on larger timber projects, which means our buildings offer strength, durability and long-term performance.
Our recent garden room with bar project and four-car timber garage show how we manage these types of projects.


Oak Structures and Structural Timber Framing
Structural timber work often forms the foundation of a larger project. Accuracy, planning and coordination are essential at this stage.
We carry out a wide range of structural timber projects across Cambridgeshire. This includes structural timber framing, timber beam installations, roof structures, oak-framed features, oak porches and specialist timber structures. Our team has extensive knowledge of structural timber construction and works closely with architects, structural engineers and contractors throughout. If you’re interested in using green oak, our guide explaining what green oak is, its benefits and where it’s commonly used explains what to expect from the material over time.
If you would like to see an example of our work, explore our oak porch case study to see how traditional timber framing can complement a modern property.


Major Refurbishments and Structural Alterations
Some projects go beyond a new extension or standalone building. We also carry out major property refurbishments involving structural alterations, property reconfiguration and significant timber construction work.
These projects often need careful coordination between multiple trades, consultants and suppliers. Where required, we act as the main contractor and manage the project on behalf of the client. As a result, communication stays clear and delivery stays organised from planning through to completion.

Who We Work With
We support a wide range of projects across Cambridgeshire as an experienced timber contractor. We work with homeowners, self-builders, developers, main contractors, architects, structural engineers, property investors and commercial property owners.
Every project is different. So, we adapt our approach to suit the scope, complexity and requirements of each build.
Project Management from Start to Finish
Many timber frame construction projects involve coordination between architects, structural engineers, building control, suppliers and specialist trades to keep everything progressing smoothly.
When required, we act as the main contractor, managing every stage of the project on your behalf. From the initial planning through to timber frame installation and final handover, we coordinate schedules, organise materials and keep communication clear between everyone involved. As a result, clients have a single point of contact throughout the build, helping projects stay organised, efficient and on schedule.
Whether you are planning a timber frame extension, a self-build home or a larger structural timber project in Cambridgeshire, our focus is careful planning, reliable delivery and quality workmanship from start to finish.
