Your home has good bones but not enough rooms. Whether you’re in a Victorian terrace in Dartford town centre, an Edwardian semi on West Hill, or a post-war estate on Temple Hill, extending upwards or outwards is often easier than moving. We design and build extensions that feel natural to your property, work with Dartford Borough Council on planning, and manage the whole job from first conversation to final inspection. An extension adds real value, gives you the space you need, and keeps you in the neighbourhood you’ve chosen. Talk to us about what you’re thinking.
A rear or side extension gives you a new kitchen, living area, or bedroom without the fuss of a loft conversion. We build these from £25,000 to £60,000 depending on size and finish. We prepare the ground properly—important on Dartford’s clay soils where settlement can be an issue. We use quality materials, manage the build schedule, and keep disruption minimal. Your garden stays as liveable as possible during work.
Go taller and you get more floor space. A two storey extension costs more—typically £50,000 to £100,000—but the return is bigger too. Structurally, these need careful engineering and solid foundations. We work with qualified structural engineers, get everything certified, and build to current Building Regulations. We’ve done dozens in Dartford. We know what works.
Wrapping around your property—often a side return kitchen or utility space—is a smart use of space without eating into your garden. These are popular in terraced properties and smaller semis. Costs run £18,000 to £45,000. We design them to tie in with your existing brickwork and style, and we manage party wall agreements with neighbours when needed. It’s detail work, but detail matters.
Planning permission isn’t always needed—some extensions fall under permitted development rules. But in Dartford’s conservation areas or on properties close to neighbours, we need to get it right. We handle the paperwork, drawings, and conversations with the council. You stay informed at every step. We know Dartford’s planners and what they want to see. Most extensions take eight to twelve weeks from application to approval.
We’re not quick-build operators. We design extensions that suit your property and neighbourhood, we get planning right, and we build carefully. We understand Dartford’s properties—the Victorian and Edwardian stock, the clay subsoils, the conservation areas. We manage structural engineers, Building Control inspections, and party wall matters as standard. We’ve worked across Dartford town centre, Temple Hill, West Hill, Princes Road, Wilmington, Hawley, Sutton-at-Hone, Longfield, Crayford, and Greenhithe. We know what local planners want and what your neighbours will accept. We won’t start work until you’re confident about the plan and the costs.
We bring experience across St Albans’ varied housing stock to every project. The Victorian and Edwardian construction through the older streets. The inter-war methods across Marshalswick. The conservation area requirements across much of the city. Each property type and each planning context demands specific knowledge that comes from working across all of them consistently.
Our quotes specify every element — groundwork, materials, steelwork, scaffolding, building control fees, and all finishing. Transparent pricing with no hidden costs.
We build extensions throughout St Albans, covering the city centre, Fleetville, Marshalswick, New Greens, Jersey Farm, Bernards Heath, Sopwell, Townsend, London Colney, Redbourn, Harpenden, and surrounding areas.
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 Milton Keynes and the surrounding area, covering Bletchley, Wolverton, Stony Stratford, Bradwell, Two Mile Ash, Shenley, Emerson Valley, Furzton, Westcroft, Kingsmead, Oldbrook, Campbell Park, Newport Pagnell, Olney, Woburn Sands, and surrounding areas.
A garden room is somewhere between an extension and a summer house. It blurs the line between indoors and outdoors and works well in Dartford’s suburban plots. Less building regulation hassle than a traditional extension, but designed with real style and quality materials.
Converting your loft gives you an extra bedroom or space without extending outwards. Many Dartford homes have loft potential. We handle the structural work, insulation, stairs, and Building Regulations approval. It’s often faster and cheaper than a ground-floor extension.
If you’re extending, now’s the time to reconfigure your kitchen. We can design the new space and fit it out together. No rewiring the kitchen twice, no moving utilities twice.
We’ll visit your home in Dartford and give you a detailed, no-pressure quote based on what we actually see.
