Tandem and landlocked plots in Llanelli

Land behind a house in Llanelli with no easy way in can still become a building plot, but only once the access is sorted. That might be a shared drive, a strip of a neighbour’s garden, a lane at the back, or a right of way that needs widening.

Before anything else, we look at the access. The free appraisal checks the title plan, existing rights, the width on the ground and the route to the road, then the planning picture with Carmarthenshire County Council. If the access can’t be made to work on sensible terms, we say so before you spend anything.

Before you decide in Llanelli

A home placed behind another changes the light as well as the traffic. In Llanelli 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. Carmarthenshire County Council decides, and its own guidance on separation distances sets the gaps it expects.

This section is worked out for the latitude of Llanelli: around 38° 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

The first step is a free, no-obligation appraisal. For a Llanelli plot with a difficult way in, that means checking who owns each part of the route, what rights exist and how wide it is on the ground. If a neighbour or a ransom strip is involved, we agree an approach with you before contacting anyone.

  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

  • Planning permission gives no right to cross land you don’t own; the legal access has to be secured separately.
  • A right of way that has served a garage or field for years may not legally cover a new house.
  • Long or narrow drives can mean extra cost for sprinklers, passing places, lighting or a bin collection point.

Llanelli: questions to ask

Will Carmarthenshire County Council accept a shared drive for a new home in Llanelli?

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.

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

Possibly. That would be a tandem layout, with the new home behind yours sharing your drive. Carmarthenshire County 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.

Could my neighbour and I in Llanelli 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.

How long does sorting access on a Llanelli 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.
