House Extensions in Maidstone
A house extension is one of the most effective ways to add space and value to your Maidstone home without the upheaval and cost of moving. We design and build bespoke extensions of every type — single-storey rear extensions, two-storey side and rear extensions, wraparound designs, kitchen-diners with bi-fold doors, and porch or entrance additions.
Maidstone’s housing stock is diverse, ranging from Victorian terraces in the town centre and 1930s semis in areas like Bearsted and Barming to larger detached family homes in surrounding villages. Each property type presents different structural opportunities and challenges when extending, and our experience across the full range means we can advise on what’s achievable — and what will deliver the best return — for your specific home.
Many extensions in Maidstone can be built under permitted development rights without a formal planning application. However, if your property falls within one of the borough’s 41 conservation areas, is a listed building, or if the proposed extension exceeds certain size thresholds, you may need planning permission from Maidstone Borough Council. We’ll assess your property and confirm the planning route before any design work begins.

Renovations & Refurbishments in Maidstone
Whether you’re modernising a tired interior, reconfiguring a dated layout, or carrying out a complete whole-home refurbishment, our renovation service transforms Maidstone properties from the inside out. We coordinate every trade under one roof — structural alterations, steelwork, re-wiring, plumbing, plastering, joinery, kitchens, bathrooms and final decoration — so you deal with one team and one point of contact throughout.
Maidstone has a significant number of older properties with genuine potential. Victorian and Edwardian houses with period features, post-war homes with scope for modernisation, and rural properties in surrounding villages that have been extended or altered over the decades are all common across the borough. We specialise in bringing these properties up to modern standards while preserving the character that makes them worth investing in.
Our approach to renovation is designed to minimise disruption. We partition living spaces so you can stay in your home during the build, maintain clean and tidy working areas, and provide regular updates so you always know what’s happening and what’s coming next.

Loft Conversions in Maidstone
A loft conversion is one of the most cost-effective home improvements available to Maidstone homeowners — adding valuable living space without sacrificing any garden footprint. With average property prices in the Maidstone borough sitting around £356,000, a well-executed loft conversion can add significant value while giving your family the extra bedroom, home office or bathroom you need.
We build every type of loft conversion — dormer, hip-to-gable, Velux (rooflight) and mansard designs — each tailored to the property type and your requirements. We manage the entire process from initial structural survey and party wall agreements through to staircase installation, electrics, plumbing, insulation, plastering and Building Control sign-off.
Most loft conversions in Maidstone can be completed under permitted development without a formal planning application. However, if your property is in a conservation area or the proposed dormer faces a highway, you may need planning permission. We’ll confirm the position for your property before committing to any design.

Garage & Barn Conversions in Maidstone
Converting an underused garage, outbuilding or barn into functional living space is a practical and cost-effective way to expand your home. Whether you need a home office, annexe, playroom, guest bedroom or self-contained living space, we handle the full conversion — from structural work, insulation and damp-proofing through to electrics, plumbing and interior finishing.
The Maidstone borough extends well beyond the urban centre into attractive rural areas where barn and outbuilding conversions are particularly common. Villages like Lenham, Hollingbourne, Headcorn, Yalding and Staplehurst all have agricultural buildings with conversion potential. We understand the structural and planning considerations involved, including the requirement for structural surveys on countryside conversions and the use of sympathetic materials within the Kent Downs Area of Outstanding Natural Beauty.
New Builds in Maidstone
Whether you’ve purchased a plot in the Maidstone area, secured planning on a garden site, or you’re planning a demolish-and-rebuild project, BDC Construction manages new builds from the ground up. We take your project from site clearance and groundworks through foundations, superstructure, roofing, first and second fix, and right through to external landscaping and final decoration.
Maidstone Borough Council places a strong emphasis on design quality and sustainability in new developments. Major projects are now required to deliver biodiversity net gain, and proposals within the Kent Downs landscape need to demonstrate sensitivity to local character. We work alongside trusted architects and planning consultants to ensure your new build meets all local policy requirements and is delivered on time and on budget.

Building Work in Maidstone — What You Need to Know
As the county town of Kent, Maidstone has a rich architectural heritage and specific planning considerations that any reputable building contractor should understand. Here’s what makes building in the Maidstone area different:
41 conservation areas — Maidstone Borough Council manages 41 designated conservation areas, covering locations across the borough from the town centre to villages including Bearsted, Boxley, Hollingbourne, Harrietsham, Lenham, Yalding, Staplehurst, Headcorn, Sutton Valence, Boughton Monchelsea and many more. In November 2024, the council adopted a new Overarching Management Plan covering conservation areas that don’t yet have individual management plans. If your property falls within a conservation area, you may need planning permission for external alterations — including dormer windows, cladding, roof changes and boundary treatments — that would otherwise be permitted development. Some areas also have Article 4 directions that remove additional permitted development rights. We can check your property’s status and advise on what permissions are needed before any work starts.
Over 2,000 listed buildings — The Maidstone borough contains more than 2,000 listed buildings, ranging from Grade I buildings of exceptional interest to the more common Grade II designations. If you’re planning any work that alters the character of a listed building — internally or externally — you’ll need Listed Building Consent from Maidstone Borough Council. This applies even to seemingly minor changes like replacing windows or internal layout alterations. It’s a criminal offence to carry out work to a listed building without consent, so working with a builder who understands the process is essential. We have experience working sensitively with protected properties and can guide you through the consent process, including recommending pre-application advice with a conservation officer.
The Kent Downs AONB — Parts of the northern and eastern borough fall within the Kent Downs Area of Outstanding Natural Beauty. Properties in these areas face additional design scrutiny, with an emphasis on using materials and forms that respect the landscape character. Extensions and new builds within the AONB aren’t prohibited, but proposals need to demonstrate they won’t harm the natural beauty of the area. We can advise on what’s achievable and help prepare applications that satisfy the planning authority.
Maidstone’s property market — Average house prices in Maidstone sit around £356,000, with detached homes averaging approximately £615,000 and semi-detached properties around £390,000. The borough’s property market has seen steady growth of around 3.7% year-on-year, making quality building work — whether an extension, loft conversion or full renovation — a sound investment that adds both living space and financial value to your home.
Countryside conversions — If you’re converting an agricultural building in the rural parts of the Maidstone borough, the council requires a structural survey from a chartered structural engineer to confirm the building is structurally sound enough for conversion. We’ve worked on conversion projects across Kent and understand the specific documentation and planning requirements involved.

Frequently Asked Questions — Builders in Maidstone
How much do builders in Maidstone charge for an extension? Extension costs in Maidstone typically range from £30,000 to £80,000 or more, depending on the size, specification and whether the build is single or two-storey. Larger two-storey extensions with high-end finishes or complex structural work will sit at the higher end. We provide detailed, itemised quotes so you know exactly what you’re paying for — with no hidden costs or surprises.
Do I need planning permission for a house extension in Maidstone? Many rear and side extensions can be built under permitted development rights without a formal planning application. However, if your property is within one of Maidstone’s 41 conservation areas, is a listed building, or if the proposed extension exceeds specific size limits, you’ll need planning permission from Maidstone Borough Council. We assess every property individually and confirm the correct planning route during your free consultation.
How long does a loft conversion take in Maidstone? A typical loft conversion takes between 8 and 12 weeks from start to completion, depending on the type of conversion and complexity of the structural work involved. Dormer and hip-to-gable conversions generally take longer than a straightforward Velux conversion. We provide a realistic schedule at the quoting stage and keep you updated at every step.
Is my property in a Maidstone conservation area? Maidstone has 41 conservation areas across the borough. You can check whether your property falls within one by visiting the Maidstone Borough Council heritage map or by contacting the council’s planning team directly. If you’re unsure, we can check for you and advise on how it affects your planned building work.
Can I convert a barn or outbuilding in the Maidstone area? Yes, barn and outbuilding conversions are common across the rural parts of the Maidstone borough. However, you’ll typically need planning permission, and the council requires a structural survey from a chartered structural engineer confirming the building is sound enough for conversion. If the building falls within the Kent Downs AONB, additional design considerations apply. We can advise on the full process during your free consultation.
