Small House Extensions in Edenbridge

Single-storey and small extensions that add a room, a bigger kitchen or a garden link, managed from groundwork to finishing.

Moving house to gain one more room is expensive and disruptive. A well-planned small extension can give you a larger kitchen-diner, a playroom, a garden room or a downstairs cloakroom while keeping the home and neighbourhood you already like.

One Stop Build & Landscaping takes on smaller-scale extensions for homeowners around Edenbridge. Because the same business also fits kitchens, lays floors and builds patios, the new room and the garden it opens onto can be planned together rather than handed between several firms.

Who a small extension suits

Extensions work best when the problem is genuinely space: a kitchen too narrow for a table, no room for a home office, or a house that lacks a link to the garden. If the issue is layout rather than floor area, an internal alteration can sometimes achieve the same result for less, and Rob will say so.

Scope: what is managed and who does what

Rob is your single point of contact. Groundwork, building, making good and interior finishing are coordinated by One Stop Build, with professional colleagues brought in for specialist elements such as structural design, electrics or plumbing where your project needs them.

Architectural drawings, structural calculations and approvals are separate professional services. Rob can explain what is likely to be required and work alongside your designer or engineer, but he does not present himself as an architect or structural engineer.

Planning, Building Regulations and neighbours

Many single-storey rear extensions fall within permitted development, but limits apply to depth, height, position and materials, and some properties have those rights removed. Almost every extension needs Building Regulations approval. If work affects a shared wall or foundations near a boundary, the Party Wall etc. Act 1996 may require you to notify your neighbours. The Planning Portal is a good starting point, and these questions are raised early so they do not delay the build.

Typical project stages

  • Site visit to discuss the room you want, access and how it connects to the house and garden
  • Confirming drawings, approvals and any structural input required
  • Setting out, excavation and foundations as specified
  • Building walls, roof structure and openings, then making the shell weathertight
  • Breaking through to the existing house at the agreed stage
  • First and second fix, plastering, flooring and decoration
  • Reinstating or improving the garden area around the extension

Cost and timing factors

Size, foundation requirements, ground conditions, roof type, the number and size of glazed openings, heating and drainage, interior specification and access for materials all influence price. Timing depends on approvals, material lead times and weather for the external stages. A clear quotation is prepared after the site visit rather than guessed from a price per square metre.

To get started, send a sketch or any drawings you already have, photos of the area, your postcode and a note of how you want to use the new space.

Living with the work

Most of the shell is built from outside, so disruption inside the house is concentrated around the break-through and finishing stages. Rob will explain when rooms will be out of use, how dust is managed and how access to the garden is kept.

Small House Extensions questions

Does my extension need planning permission?

It depends on the size, height, position and your property type. Many modest single-storey rear extensions are permitted development, but limits apply and some homes, such as those in conservation areas or with earlier extensions, may need full permission. Check the Planning Portal or your council, and Rob will flag likely issues at the first visit.

Will I need Building Regulations approval?

Almost certainly. Extensions must meet standards for structure, insulation, drainage, ventilation, fire safety and electrics. Approval is obtained through local authority building control or an approved inspector, with inspections at key stages. Rob plans the build around these inspections.

Do I need an architect or structural engineer?

Most extensions need drawings to obtain approvals, and steel beams or new openings need structural calculations. Rob can work with your chosen professionals or explain what is likely to be needed. He will not guess a structural specification.

What is a party wall notice and does it apply to me?

The Party Wall etc. Act 1996 applies when building on or near a shared boundary, digging foundations close to a neighbour's building, or working on a shared wall. You may need to serve notice before work starts. Speaking to neighbours early usually makes the process smoother.

How do you connect the extension to the existing house?

The shell is usually built and made weathertight first, then the opening into the existing house is formed at a planned stage, supported as specified by the engineer. This keeps the time your home is open to the elements and dust to a minimum.

Can I stay at home while the extension is built?

Most people do. External building happens largely outside the house. The most disruptive stages are breaking through, connecting services and finishing. Rob will explain in advance which rooms will be affected and when.

What affects the cost of a small extension?

Floor area, foundations and ground conditions, roof style, glazing, heating, drainage connections, the level of interior finish and site access are the main factors. Approval and design fees are separate. A site visit allows these to be priced properly.

Can you also fit the kitchen or bathroom in the extension?

Yes. Kitchen and bathroom fitting, flooring and tiling are part of the wider service, so the room can be completed rather than left as a shell for another firm to finish.

What happens to the garden around the extension?

Building work inevitably affects the area outside. Because One Stop Build also lays patios, paths and fencing, the garden can be reinstated or improved as part of the same project, with levels and drainage considered alongside the new doors.

What should I send when asking for a quotation?

Any drawings or sketches, photographs of the area, approximate dimensions, your postcode, whether approvals are in place and how you plan to use the space. Mention access restrictions such as narrow side passages, as these affect how materials are delivered.
