Tandem and landlocked plots in Gelligaer

A tandem plot in Gelligaer 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 Caerphilly County Borough Council applies, so you know early whether the land is worth pursuing and which route fits.

The local picture in Gelligaer

A home placed behind another changes the light as well as the traffic. In Gelligaer the sun peaks at roughly 38° 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. Caerphilly County Borough Council decides, and its own guidance on separation distances sets the gaps it expects.

Noon sun in Gelligaer on 21 March sits about 38° 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 Gelligaer

Once you get in touch about land in Gelligaer, we look at the title plan and any rights of way from the desk, then talk it through with you. If the access looks workable, we visit and measure the route, including the junction with the road. You get a plain account of the options before any planning work starts.

  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. Title and access check

    With your solicitor we confirm who owns every strip between the plot and the road, what rights already exist and whether they cover a new home. Any ransom strip or missing right shows up at this stage.

  3. 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.

  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

  • A right of way that has served a garage or field for years may not legally cover a new house.
  • Buying out a ransom strip or a neighbour’s land costs money and time, and the other owner can say no.
  • Access is usually the deciding factor on these plots, so a large plot with a poor way in may not be a building plot at all.

Gelligaer: questions to ask

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

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.

How long does sorting access on a Gelligaer plot usually take?

It varies. Confirming an existing right of way can take a few weeks of solicitor time. Negotiating with a neighbour or a ransom strip owner often takes longer, and depends on how quickly everyone agrees and takes advice. Once we’ve seen the title and the route, we can give you a sensible estimate.

Could my neighbour and I in Gelligaer share one new access?

Often, yes. If both your gardens are long, combining them can give one shared drive and a better layout than either garden alone. Each owner keeps their house, and a written agreement sets out how the value is shared fairly.

What if a neighbour in Gelligaer owns the strip I need to cross?

Then you need their agreement, either to buy the strip or to grant a right of way over it. Terms are negotiated, often as a one-off payment or a share of the value the access creates. Both sides should take legal advice. We can make the approach with you.
