Building in a large rear garden in St Albans

There are two broad ways to use spare land at the back of a house in St Albans. The first is to sell it: outright, subject to planning, through an option, or alongside your neighbours. The second is to keep it and have a new home designed, approved and built on it for you.

Which suits you depends on how much risk and involvement you want, and on what the plot can realistically take. A single bungalow, a two-storey home, or a pair sharing one drive across two gardens are all possible on the right site. We look at yours first, free of charge, and explain the trade-offs.

Before you decide in St Albans

Overshadowing is often the deciding issue in a long garden. At midday on 21 March the sun in St Albans stands about 38° above the horizon, so a typical two-storey eaves line throws a shadow of roughly 6.3 m. In midwinter the noon sun is only about 15° up and shadows stretch around three times as far.

That’s why the gap between a new home and neighbouring gardens matters, and why a lower roof, or a home set further from the boundary, can make a scheme acceptable. We check the shadows on your actual plot rather than relying on rules of thumb.

The next steps, locally

Send us your address in St Albans and a rough idea of what you’d like. We check the planning history around you and the policies St Albans City and District Council applies, and look for anything in the title that could get in the way. If the garden passes those checks, we arrange a visit at a time that suits you and explain each route in plain terms.

  1. Free plot appraisal

    We look at your garden using maps, the title plan and the planning history around you, then talk it through with you. If it looks workable we arrange a site visit. There’s no cost and no obligation.

  2. Measure and test the layout

    We check depth, the width of the way in, levels, trees, drains and what lies behind, then sketch what could realistically fit: one home, two, or nothing worth pursuing, before anyone pays for an application.

  3. Planning application

    We prepare the drawings and reports, usually take pre-application advice, and submit. The council consults neighbours and decides. Small schemes often take a few months from submission, longer if surveys or amendments are needed.

  4. Sale or build

    If you sell, your solicitor handles the transfer of part and your lender’s release of the plot. If you build, we give a written quote after design and survey, then build and hand over the new home.

Worth checking early

  • Surveys and drawings cost money before any decision. On a subject-to-planning sale we normally fund them; on a build you do.
  • Cars passing beside your house to reach the new home bring noise and headlights; screening helps but doesn’t remove it.
  • A covenant, a mortgage, a public sewer or a protected tree can slow a scheme down or stop it altogether.

St Albans: questions to ask

Who decides planning for a home in a St Albans back garden?

St Albans City and District Council decides, using the council’s Local Plan, national policy and any local design guidance. It consults neighbours and other bodies before reaching a decision. We prepare the application and deal with the planning officer, but the outcome is always the council’s call.

Does it cost anything to have my St Albans garden looked at?

No. The garden plot appraisal is free and carries no obligation. It starts with a desktop check and a conversation, and we arrange a site visit if your garden looks viable. You only commit to anything once you’ve chosen a route and seen the terms in writing.

Can I sell the end of my garden in St Albans and keep my house?

Yes. The plot is sold as a transfer of part and gets its own title at HM Land Registry. If your house is mortgaged, your lender must agree to release the plot. We can buy suitable plots with or without planning, always subject to survey, title and contract.

Can you build a home for my family in my garden in St Albans?

Yes. If you keep the land, we can design the home, apply for planning permission, build it once permission is granted and arrange the structural warranty lenders usually expect. You receive a written quote after design and survey. If the home is for a relative who will share your kitchen and front door, an annexe may suit better.
