A House Extension is One of the Biggest Decisions You’ll Make About Your Home

Moving is expensive, disruptive and uncertain. For many Dorking homeowners, extending makes far more sense – adding the space you actually need without uprooting your family, leaving your neighbourhood or taking on the cost of stamp duty and estate agents.

But an extension is a significant undertaking. It takes over part of your home for weeks or months. There are foundations to dig, walls to build, roofs to tie in, utilities to reroute. At every stage, the quality of the work matters – because unlike a coat of paint, what goes wrong in an extension tends to stay wrong.

What makes it stressful isn’t usually the building itself. It’s the uncertainty. Not knowing how long it will really take. Not being told when the schedule changes. Living around a building site and feeling like you have no control over your own home.

As experienced builders in Dorking, we’ve seen what a well-managed extension looks like – and we know the difference it makes to the people living through it. It comes down to communication, planning and being honest when things need to be discussed.

Dorking’s House Extension Builders – Built on Local Knowledge

DFB Building and Landscaping has been building extensions across Dorking and the surrounding villages since 2007. We’re a family-run team who live and work in this area – familiar with the property types across the town, the plot shapes and constraints that come with Surrey Hills settings, and the planning considerations that apply to homes in and around Dorking.

We handle everything from the groundwork and foundations through to the finished structure. You get a single, consistent team on your project from start to finish – not a string of different subcontractors passing the job between them. That matters for quality, and it matters for communication.

House Extension Services in Dorking

Every property is different. We work with you to understand what your home needs and what will work within your plot, budget and planning constraints.

Single Storey Rear Extensions

The most common extension in Dorking. Opening up the back of the house to create a larger kitchen, dining area or living space. We handle everything from foundations and blockwork through to the roof structure and weatherproofing – leaving a clean shell ready for your finishers.

Double Storey Extensions

Adding space on two levels makes the most of your footprint and budget per square metre. More complex structurally, which means the build quality at foundation and structural level is critical. We take the time to get the groundwork and frame right before anything else.

Side Return Extensions

Many Dorking properties have an underused side passage that can be brought into the main floorplan. A side return extension transforms the layout of a home without extending into the garden. Tight access and careful tie-in to the existing structure are where experience counts.

Wraparound Extensions

Combining a rear and side return to maximise the ground floor. A wraparound creates significant new space and completely changes how a home flows. These are larger projects that demand careful planning and precise execution at every stage.

Garage Conversions & Extensions

Converting an existing garage, or extending over it, is often the most cost-effective way to add usable space. We assess the existing structure honestly and advise on what’s viable – whether that’s a straightforward conversion or a more involved structural project.

Structural Alterations & Openings

Many extensions require internal walls to come down or openings to be formed to connect new space with old. We handle the structural elements – RSJs, lintels, temporary support – that make the new layout work safely and properly.

Living Through a Build – What We Do Differently

An extension means builders in your home, often for several weeks. How that experience feels day to day comes down to how a team operates. Here’s what we commit to on every project.

You’ll always know what’s happening

Before work starts each week, we’ll walk you through what to expect. If the schedule changes, you’ll hear from us directly – not find out by looking out the window.

We respect your home

We’re working in the place you live. We protect floors and surfaces, contain dust where we can, and treat your property with care throughout – not just at the end when you’re doing the snagging walk.

The site is tidy at the end of every day

Rubble, materials and tools are managed properly. We don’t leave your garden or driveway looking like a skip yard overnight. A tidy site is a safe site – and it makes the whole experience more bearable.

No hidden surprises on the bill

Your quote is clear and detailed. If something genuinely unforeseen comes up – unexpected ground conditions, a structural issue behind an existing wall – we tell you straight away, explain what it means and agree how to proceed before we do anything.

How Your Extension Project Works

From first contact to finished structure, here’s what working with DFB on a house extension in Dorking looks like.

Initial Conversation

Tell us what you’re thinking – what space you need, rough timelines, whether you have planning permission yet. No commitment. We’ll give you an honest steer on what’s realistic.

Site Visit & Detailed Quote

We visit your property, assess the existing structure and plot, and put together a clear, written quote. We’ll talk through any constraints or considerations specific to your home.

Planning & Programme

Once you’re happy to proceed, we agree a start date and build programme. You’ll know the sequence of works and roughly how long each phase will take before we break ground.

Build Phase

We get on with the work – keeping you updated as each phase completes. Groundwork, foundations, structure, roof. Every stage signed off before the next begins.

Handover

When the structure is complete, we walk you through everything. You get a clean, weather-tight shell ready for your architect’s next phase – or a finished space if we’re doing the full fit-out.

What a Well-Built Extension in Dorking Gives You

More space is the obvious result. But a properly planned, well-managed extension gives you something beyond square footage – a home that works better, built by people you could trust throughout the process.

The space your family actually needs – without the cost of moving

A structure built right – solid foundations, proper tie-ins, no shortcuts

A build process that was communicated clearly from start to finish

Minimal disruption to your daily life throughout the project

A finished result that adds real value to your Dorking property
