When your home runs out of space, an extension is almost always a better investment than moving. You avoid the estate agent fees, stamp duty, solicitor costs, and the upheaval of uprooting your family, and instead put that money into creating exactly the space you need in the location you’ve already chosen. With strong transport links from the Medway Towns into London and property values that reward investment in additional space, extending makes financial sense as well as practical sense for most homeowners across the area.
We design and build house extensions across Gillingham, Chatham, Rochester, Strood, Rainham, and the wider Medway area, handling every stage from initial concepts and planning applications through to construction and finishing. Single storey rears that open onto the garden, double storey additions that add bedrooms above and living space below, side returns that widen a narrow kitchen, and wrap-around designs that maximise every available metre — we build them all and manage every trade involved.
Our service covers the complete project. We coordinate groundwork, structural steelwork, bricklaying, roofing, carpentry, plastering, electrics, plumbing, flooring, and decoration. One team from the first foundation trench to the final coat of paint, with clear communication and transparent pricing throughout. Contact us to discuss your extension.
A single storey extension is the most popular project we build across the Medway Towns. It adds ground floor space for a larger kitchen-diner, a generous living area, a home office, or a ground floor bedroom without the cost and complexity of building upward. Under permitted development, you can typically extend three metres from the original rear wall for attached houses or four metres for detached properties without planning permission. Larger extensions up to six or eight metres are achievable through the prior approval process. We design single storey extensions that flood with natural light through bi-fold doors and skylights, creating bright, open rooms that connect your interior with the garden. The terraces through Gillingham and the semis across Chatham and Rainham respond particularly well to this treatment, transforming cramped separate rooms into flowing living spaces.
When you need space on both floors, a double storey extension delivers the most room for your investment. Building two storeys shares foundations, walls, and roof structure across both levels, costing significantly less per square metre than constructing the same area as separate single storey projects. The ground floor typically provides an enlarged kitchen-diner or living space while the first floor adds bedrooms, bathrooms, or an ensuite above. Double storey extensions require planning permission in most cases and need careful design to minimise impact on neighbouring properties. We design double storey additions across Medway that match the proportions, materials, and roofline of your existing home, ensuring the extension looks like it belongs rather than appearing as an obvious bolt-on addition.
Many properties across the Medway Towns — particularly the Victorian and Edwardian terraces through Gillingham, Rochester, and the older streets of Chatham — have narrow side passages that serve little practical purpose beyond storing bins and collecting leaves. Extending into this strip adds valuable width to your ground floor without consuming garden space. A side return transforms a cramped galley kitchen into a room with genuine breathing space. Combine it with a rear extension and you create a wrap-around design — an L-shaped addition that maximises the ground floor footprint in one coordinated project. Wrap-around extensions deliver the most dramatic transformations, often doubling the usable kitchen and living space. We design both approaches to maintain natural light to existing rooms while creating the largest possible gain.
The kitchen-diner extension is the single most requested project we build across Medway. It combines a rear extension with removal of the internal wall between kitchen and dining room, creating one generous open-plan space for cooking, eating, and family life. The result fundamentally changes how the ground floor works — a bright, sociable room with space for a proper kitchen, a dining table, and often a seating area, all flowing together and opening onto the garden through bi-fold or sliding doors. We handle the structural steelwork for the removed wall, the kitchen fitting, flooring, and all finishing trades to deliver a completed room rather than a shell. Kitchen-diner extensions across the Medway Towns typically complete within ten to fourteen weeks from breaking ground to handover.
An extension is one of the largest investments most homeowners make in their property, and the builder you choose determines the quality of the result, the smoothness of the process, and whether the project finishes on time and within the budget agreed. We bring years of experience to every extension project across the Medway Towns, combining structural knowledge and quality craftsmanship with the kind of project management that keeps work moving without gaps, delays, or surprises.
We provide detailed, itemised quotes specifying exactly what’s included — groundwork, materials, labour, steelwork, scaffolding, building control fees, and all finishing. You know the cost before we start, and if anything changes during the build we discuss it openly before proceeding.
We build house extensions throughout the Medway Towns and surrounding Kent, covering Gillingham, Chatham, Rochester, Strood, Rainham, Walderslade, Lordswood, Wigmore, Hempstead, Parkwood, Borstal, Cuxton, Sittingbourne, Maidstone, and surrounding areas.
If extending your main house isn’t feasible or you need a separate dedicated space, a garden room provides the alternative. We build bespoke insulated garden rooms across Medway with quality cladding, high-specification glazing, built-in heating, and professional electrical installations. Every room is designed for year-round comfort with proper insulation and services from the start. Most proceed under permitted development without a planning application. A garden room and a house extension serve different purposes — one adds space within the home, the other creates space apart from it — and some Medway homeowners choose both.
From single-room refurbishments to complete property transformations, we handle building work that crosses trade boundaries across the Medway Towns. Our service covers structural alterations, wall removal, layout reconfiguration, rewiring, replumbing, plastering, flooring, and decoration. We also carry out garage conversions, general building including patios, garden walls, and brickwork, and the projects that need broad practical capabilities. Combining an extension with a wider renovation delivers a transformed property in one coordinated programme — new space and updated existing rooms completed by one team without gaps between separate projects.
