Backland development in Portsmouth

Some gardens in Portsmouth are long enough, or wide enough, to take a new home without crowding the houses around them. Others aren’t, and it’s better to know which you have before spending money on drawings. That’s what our free garden plot appraisal is for.

We check the size and shape of the plot, how a car and a fire engine could reach it, what the title says, which trees are protected and what the council’s Local Plan says about garden land. Then we tell you plainly what we think. If it could work, we’ll explain the routes, from selling the plot to keeping it and having us build on it. If it can’t, we’ll say so.

The kinds of plot we look at in Portsmouth

Sometimes the plot that works isn’t a single garden at all. Two or three adjoining back gardens in Portsmouth can often be combined into one scheme with one shared access, giving a better layout than any of them alone. Each owner keeps their house, and a collaboration agreement with an equalisation clause shares the value fairly. If your own garden is too narrow or too short to work on its own, it’s worth asking whether the neighbours might be interested too.

Planning and light in Portsmouth

Shadows tell a council a lot about a garden plot. In Portsmouth, the noon sun on 21 December reaches only about 16° above the horizon, while by 21 March it has climbed to around 39°, when a 5 m eaves line casts a shadow of roughly 6.1 m. On a garden plot anywhere in PO1, PO2, PO3 and PO4, that difference shapes how far apart the old and new homes need to be, which windows face which way, and whether a single-storey or roof-lit design would sit more comfortably. Planning officers at Portsmouth City Council will expect those effects on neighbours to be understood before they decide.

This section is worked out for the latitude of Portsmouth: around 39° of sun at midday in late March and about 16° 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.

What happens next

When you’re ready, tell us about your land in Portsmouth. A few photos help but aren’t essential. We’ll come back with a straight view of whether the plot could take a new home and which routes might suit you, from a sale to design and build. If it’s not a good fit, we’ll say so, and there’s nothing to pay either way.

Questions about garden plots in Portsmouth

Can I sell part of my garden in Portsmouth?

Often, yes, if the plot is big enough, has a workable access and stands a reasonable chance of planning. We buy suitable plots directly, with or without planning, subject to survey, title and contract, or agree a sale that only completes if Portsmouth City Council grants permission. If planning is refused on a conditional sale, you keep your land.

What happens if planning is refused for a plot in Portsmouth?

If you agreed a sale subject to planning, the contract doesn’t complete and you keep your land. We’ll then look at the reasons Portsmouth City Council gave and tell you honestly whether a revised application, an appeal or stopping is the sensible choice. Nothing about your own house changes.

Do you look at garage courts and yards in Portsmouth?

Yes. Garage courts, lock-up blocks, old yards and outbuildings behind houses can sometimes take a new home, especially where a vehicle access already exists. We check who owns the access, what rights others have over it and what the ground was used for, as part of the free appraisal.

Can I team up with my neighbours in Portsmouth?

Yes, and it can make a weak plot workable. Combining adjoining gardens can allow one shared access and a better layout. Each owner keeps their house, and a collaboration agreement sets out decisions, costs and how value is shared through equalisation. Every household should have its own solicitor.
