Building in a large rear garden in Washington

Not every long garden in Washington should be built on, and we’d rather tell you that early. A deep plot with a narrow side gap, a steep slope or a big protected tree may be better left as garden. Others have enough depth and a usable way in to take a well-placed new home.

Our free appraisal sorts one from the other. If yours works, you can part with the land while staying in your house, agree an option or a conditional sale, or keep it and have us design and build. If it doesn’t, you’ve lost nothing but a conversation.

Washington: light, access and policy

Look along your road and the roads behind it. If homes in Washington or in Houghton-le-Spring, Hebburn and Sunderland already stand behind the original houses, that shows the council the pattern exists locally, although it never makes a new permission certain. Where back gardens are unbroken, a first home behind the street faces closer scrutiny.

How much weight that carries is set out in the council’s Local Plan and in any design guide adopted by Sunderland City Council. We read both before drawing anything, so your scheme answers the questions the planning officer is likely to ask.

This section is worked out for the latitude of Washington: around 35° of sun at midday in late March and about 12° 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

Send us your address in Washington and a rough idea of what you’d like. We check the planning history around you and the policies Sunderland City 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

  • A covenant, a mortgage, a public sewer or a protected tree can slow a scheme down or stop it altogether.
  • Neighbours are consulted and may object. The council decides, and a carefully designed scheme can still be refused.
  • Cars passing beside your house to reach the new home bring noise and headlights; screening helps but doesn’t remove it.

Your questions, answered for Washington

Can I build a house in my back garden in Washington?

Possibly, if the garden is deep enough, has a safe way in and a new home wouldn’t harm the neighbours or the character of the street. A new separate home always needs planning permission, and Sunderland City Council makes the decision. A free appraisal will tell you whether your garden is worth taking further.

Can you build a home for my family in my garden in Washington?

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.

How do I find out if my Washington garden is big enough for a house?

Ask for a free garden plot appraisal. We measure depth and the width of the way in, check what lies behind, look at levels, trees and drainage, and compare your garden with your council’s separation and garden-size guidance. Size alone rarely settles it, because access and neighbours’ privacy matter just as much.

Can I sell the end of my garden in Washington 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.
