Building in a large rear garden in Greenwich

If you have a long rear garden in Greenwich, the first question is usually the obvious one: is there really room for a house down there? The honest answer comes from measuring, not guessing. Separation from existing back windows, garden space for both homes and a drive that works for cars, bins and emergency access all have to fit.

Once we know what could realistically go there, you pick the route that suits you. Some owners prefer a clean sale of the plot, with or without planning. Others want the new home itself, for a parent, a grown-up child or to let. We handle the design and the planning application either way.

The local picture in Greenwich

Wherever your home sits within SE2, SE3, SE7 and SE9, the street around it shapes what’s possible. Some roads already have houses built behind the originals, while elsewhere the gardens stay unbroken from end to end. Councils read that pattern when judging a new home, so we look at your surroundings as well as your plot.

The same applies if you live just outside Greenwich, in nearby places such as Lewisham, Bexley and Newham. The first step doesn’t change: a free look at depth, access, levels and what a new home would mean for the people next door.

Noon sun in Greenwich on 21 March sits about 39° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.3 m. In December the sun is only about 15° up and shadows stretch much further. Drawn for a garden facing north, where it matters most.

The next steps, locally

An enquiry about a Greenwich garden can start with a short call and a few photos of the garden and the side of the house. A desktop check follows, then a site visit if it’s worth one. If you choose to sell, we agree heads of terms and your solicitor takes it from there. If you choose to build, we move on to a measured survey and design, and a written quote follows.

  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. Choose your route

    You decide whether to sell the plot outright, sell subject to planning, grant an option, team up with neighbours, or keep the land and have us design, get planning for and build a home on it.

  4. 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.

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.
  • Neighbours are consulted and may object. The council decides, and a carefully designed scheme can still be refused.

Your questions, answered for Greenwich

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

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 long does planning take for a garden home in Greenwich?

It varies. Small schemes often take a few months from submission to decision, and longer if surveys, amendments or extra consultation are needed. Pre-application advice and early surveys add time at the start but can save time later. We won’t promise a date, because the council sets the pace.

How do I find out if my Greenwich 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 build a house in my back garden in Greenwich?

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 the Royal Borough of Greenwich makes the decision. A free appraisal will tell you whether your garden is worth taking further.
