Tandem and landlocked plots in Calne

A tandem plot in Calne is one where a new home would sit directly behind an existing one and share its drive. A landlocked plot is one with no legal way in of its own. Both come up often on long gardens and older back land.

Either can work, but councils look closely at the effect on the front house, and the legal access must be secure before anything is built. We check both sides of that question together, with your solicitor and against the policies Wiltshire Council applies, so you know early whether the land is worth pursuing and which route fits.

What the council will look at in Calne

A home placed behind another changes the light as well as the traffic. In Calne the sun peaks at roughly 39° in late March and barely 15° at the winter solstice, so shadows from even a modest building stretch a long way across a garden in the darker months.

That is why many tandem schemes use a single-storey or low-eaves design. It keeps upstairs windows from looking over neighbours and limits shadow. Wiltshire Council decides, and its own guidance on separation distances sets the gaps it expects.

This section is worked out for the latitude of Calne: around 39° of sun at midday in late March and about 15° 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.

From first call to decision

Call us or use the form and tell us roughly where the land is and how you reach it now. We check the title and the planning history around Calne, then come back to you. If the access can’t be secured on sensible terms, we’ll say so plainly and early, and there is nothing to pay for the appraisal.

  1. Free plot appraisal

    We start with the access, not the plot: title plans, rights of way, the width on the ground and the route to the road. It’s a desktop check and a conversation, with a site visit if it looks viable, at no cost.

  2. Secure the way in

    If a right of way needs widening, a strip needs buying or a neighbour needs to come in, we agree the approach with you and negotiate it, so the terms are settled before planning money is spent.

  3. Planning application

    We design a layout that answers the access, privacy and neighbour questions councils ask about tandem and backland plots, then apply. The council consults neighbours and decides, and the decision is always the council’s.

  4. Sale or build

    Depending on the route you chose, the sale completes through a transfer of part, or you keep the land and we give a written quote for building the new home after design and survey.

Worth checking early

  • Long or narrow drives can mean extra cost for sprinklers, passing places, lighting or a bin collection point.
  • Tandem layouts affect the front house’s privacy and quiet, and councils weigh that carefully.
  • Buying out a ransom strip or a neighbour’s land costs money and time, and the other owner can say no.

Calne: questions to ask

How do I find out if a lane behind my Calne home is a public road?

The highway authority keeps a list of streets maintained at public expense, and anyone can inspect it free of charge. If the lane isn’t on it, it’s probably private, and you’ll need to know who owns it and whether your title gives a vehicle right of way that would cover a new home.

Can I build behind my house in Calne if the only way in is my drive?

Possibly. That would be a tandem layout, with the new home behind yours sharing your drive. Wiltshire Council will look at the effect of cars passing your house, privacy, garden space and whether it suits the area. Fire and bin access also need checking. The decision is the council’s, and a good design improves the odds.

Will Wiltshire Council accept a shared drive for a new home in Calne?

It can, but shared drives are looked at closely. The council will consider the width, visibility at the road, the effect on the house beside the drive, and whether fire and bin access work. A drive with a clear gap from windows and screening alongside generally fares better.

Is a sprinkler system needed for a home at the end of a long drive in Calne?

It may be. In England, where a fire engine can’t get within 45 metres of all points inside the home, other measures, often sprinklers, may be accepted if building control and the fire service agree. In Wales, every new house needs sprinklers anyway. Building control decides what’s needed for the specific layout.
