Building on a corner plot or side garden in Southwark

A wide side garden or double driveway beside a Southwark house is one of the more straightforward places to add a home, because the new house can line up with its neighbours and have its own drive. It still needs planning permission, and the London Borough of Southwark will judge how it sits in the street.

Our free appraisal looks at width, the gaps between houses, side windows, parking and what lies under the ground. Then we explain both routes in plain terms: selling the land while you stay put, or keeping it and having a new home designed and built for you.

Before you decide in Southwark

For a corner or side plot in Southwark, the decision rests with the London Borough of Southwark. Its starting point is the council’s Local Plan, read alongside national policy and any design guidance it has adopted, which usually covers how a new home should line up with, space itself from and match the height of the houses around it.

Our designs begin with those documents rather than a standard house type. Where it helps, we seek pre-application advice, so the home we propose answers local expectations before an application goes in.

Noon sun in Southwark 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.

What happens next in Southwark

An enquiry about a side plot in Southwark can begin with a quick call and a couple of photos of the side of your house and the street. We follow up with a desktop appraisal and, if it’s promising, a site visit. If you sell, heads of terms come next and your solicitor takes over. If you build, we move to survey and design, then a written quote.

  1. Free plot appraisal

    We look at your plot on maps, the title plan and street views, check planning history nearby and talk it through with you. If a home beside yours looks possible we visit. No cost, no obligation.

  2. Choose your route

    Sell the plot outright, sell it subject to planning, or grant an option while you keep your house. Or keep the land and have us design, get planning for and build a new home on it.

  3. Design and planning

    We draw a home that sits in the street rather than fighting it, usually take pre-application advice, and submit the application. The council consults neighbours and decides; small schemes often take a few months.

  4. Sale or build

    For a sale, your solicitor handles the transfer of part and any release from your lender. For a build, a written quote follows design and survey, then we build, arrange the warranty and hand over.

Worth checking early

  • Losing a side garden or drive changes how your house works day to day, from parking to getting bins round the back.
  • The council decides, and neighbours are consulted; a sensible design can still be refused or need changes.
  • Attaching a home to yours brings party wall, fire and sound separation work, and changes the feel of your own house.

Southwark: questions to ask

Is my Southwark side garden wide enough for a new house?

It depends on how wide homes are in your street, the gaps between them, whether the new home would be attached or detached and what the council’s design guidance says. There’s no single minimum width. We measure your plot and the street as part of a free appraisal.

Can I build a house on my corner plot in Southwark?

Possibly, if a new home would respect the building lines, keep the corner feeling open enough and allow safe visibility for drivers. It needs planning permission, and the London Borough of Southwark decides. Our free appraisal tells you whether your corner is worth taking further.

Will a new drive near the corner be allowed in Southwark?

Only if drivers would have a clear enough view of the road and the junction stays safe. The highway authority comments on this and controls new dropped kerbs. Drives very close to a corner are often resisted, so we check the position on site before designing.

Is there a fee for checking my side plot in Southwark?

There’s no fee. The appraisal is free and you’re under no obligation. We work from maps, the title and a phone call first, and only visit if the plot seems worth it. Nothing binds you until you’ve picked a route and read the written terms.
