Build a new home in your garden in Dartford

A new home in your Dartford garden can be built to sell, to let or for someone in the family, and the right design differs for each. A home for sale needs its own title, a structural warranty for buyers’ lenders and a layout with wide appeal. A family home might put level access or a shared garden gate first.

We talk that through at the start, because it changes the size, the specification and the legal set-up. From there we take the plot through design, planning, approvals and construction, handing over a finished home with its certificates and warranty documents.

Dartford: light, access and policy

Access is where a garden plot anywhere in DA1 and DA2 tends to succeed or fail. A new drive needs enough width for cars, clear visibility where it meets the road, and enough distance from neighbouring windows to keep noise and headlights in check.

Policies in the council’s Local Plan, along with any highways advice the council receives, decide the detail for your address. We measure the gap beside your house on the first visit, and if it’s too tight for a home that can be approved and built safely, we’ll tell you before any design fees are spent.

This section is worked out for the latitude of Dartford: around 39° of sun at midday in late March and about 15° at midwinter. It shows why the gap between your house and a new home behind it is about light as well as privacy. Garden assumed to face north.

The next steps, locally

From appraisal to a decision from Dartford Borough Council, each step in Dartford is agreed before it starts. After the site visit we quote for survey and design; after design we prepare the application; after permission we deal with conditions and technical approvals and give you a written build quote. Each stage is a separate decision for you, with its cost set out first.

  1. Free plot appraisal

    We check the title plan, access, constraints and planning policy from our desk, talk the plot through with you, and visit if it looks viable. There’s no cost and no obligation.

  2. Planning and approvals

    We submit the planning application and manage it to a decision, then deal with conditions, Building Regulations approval, the structural warranty, any build-over agreement and the new utility connections.

  3. Written quote and build

    Once design and survey are complete you get a written quote. The build runs in stages — access and groundworks, foundations, frame and roof, fit-out and external works — with inspections at each key point.

  4. Handover

    You receive the completion certificate, warranty documents, Energy Performance Certificate, manuals and utility details, so the new home is ready to move into, let or put on the market.

Worth checking early

  • You fund the build and carry the cost risk; ground conditions, sewer diversions or supply upgrades found later can move the price.
  • Your own garden gets smaller and the new home will be visible from your house, so screening and separation matter for both homes.
  • Building and selling a new home can change your tax position compared with selling only your house; take advice from a tax adviser first.

Dartford: questions to ask

How close can a new house be to my own in Dartford?

There’s no single national distance. Many councils use separation guides of around 21 metres between facing back windows and around 12 to 15 metres between a back window and a blank side wall, but the guidance used by Dartford Borough Council decides. Window positions, ground levels, roof shape and screening all affect what is acceptable, which is why we survey before we design.

How long does planning take for a new home in a Dartford garden?

The statutory period for deciding a minor application, such as a single new home, is 8 weeks from the date the council receives a valid application, in both England and Wales. In practice many applications take longer, and the council may ask you to agree an extension in writing. Surveys and design before submission add time, and conditions may need approving afterwards.

Can I build a house in my Dartford garden and then sell it?

Yes. You keep the land while the home is built, then sell the finished house. Before building starts, the plot should be given its own title through a transfer of part at HM Land Registry, and if your house is mortgaged your lender must agree to release the plot. Selling a home you’ve built can change your tax position, so take advice from a tax adviser first.

Will I pay Community Infrastructure Levy on a new home in Dartford?

Only if Dartford Borough Council has adopted a Community Infrastructure Levy charging schedule; not every council has. Where it applies, it can be charged on a new home of any size. A self-build exemption exists for people building a home to live in, but it must be claimed before work starts, so we check the position at design stage.
