Build a new home in your garden in Aberdare

Building a second home behind your own in Aberdare is a construction project with one unusual feature: you live beside the site from the first spade to the last coat of paint. That shapes how we plan it, from the fence that separates your garden on day one to where deliveries park.

The route covers everything between an idea and a finished house. We survey and design, prepare and submit the planning application, arrange Building Regulations approval and the structural warranty, organise new water, drainage and electricity connections, and then build. You keep ownership of the land throughout.

The local picture in Aberdare

Wherever your house sits across CF44, a new home behind it needs water, power and two kinds of drainage — one for waste, one for rain. We contact the utility providers early, because a long cable run, a sewer at the wrong depth or a public pipe under the lawn can change both the layout and the cost.

Rain from the new roof and drive has to be dealt with on site, and Rhondda Cynon Taf County Borough Council will want to see how. Where a public sewer crosses your garden, the water company may also need a build-over agreement before work starts, so we check sewer records at appraisal stage.

This section is worked out for the latitude of Aberdare: 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.

The next steps, locally

From appraisal to a decision from Rhondda Cynon Taf County Borough Council, each step in Aberdare is agreed before it starts. After the site visit we quote for survey and design; after design we prepare the application; after permission we deal with conditions and technical approvals and give you a written build quote. Each stage is a separate decision for you, with its cost set out first.

  1. Free plot appraisal

    We check the title plan, access, constraints and planning policy from our desk, talk the plot through with you, and visit if it looks viable. There’s no cost and no obligation.

  2. Survey and design

    A measured survey records levels, boundaries, trees and neighbouring windows. We then design a layout and house that suit the plot, the street and your budget, and decide whether pre-application advice is worth seeking.

  3. Planning and approvals

    We submit the planning application and manage it to a decision, then deal with conditions, Building Regulations approval, the structural warranty, any build-over agreement and the new utility connections.

  4. Handover

    You receive the completion certificate, warranty documents, Energy Performance Certificate, manuals and utility details, so the new home is ready to move into, let or put on the market.

Worth checking early

  • Planning can be refused, and money spent on surveys, design and the application isn’t recovered if it is — which is why we start with an appraisal.
  • Your own garden gets smaller and the new home will be visible from your house, so screening and separation matter for both homes.
  • A build next door means months of noise, deliveries and contractors near your home; good planning reduces the disruption but doesn’t remove it.

Your questions, answered for Aberdare

Can the new home in my Aberdare garden connect to the main sewer?

Usually, yes, but the route and depth decide how easily. The new home needs its own foul connection, agreed with the water company, and gravity drainage is simplest where the sewer sits lower than the new floor. If it doesn’t, a pumped connection may be needed. Where a public sewer runs under your garden, a build-over agreement or diversion may also be required.

Who decides planning for a garden house in Aberdare?

Rhondda Cynon Taf County Borough Council decides applications for addresses in Aberdare, using the council’s Local Development Plan (LDP), national policy and its own design guidance. Neighbours and consultees such as highways officers can comment, and the decision is made by the council’s planning officers or, where the rules allow, its planning committee. Pre-application advice from the council can help test a scheme before the formal application is submitted.

Will I pay Community Infrastructure Levy on a new home in Aberdare?

Only if Rhondda Cynon Taf County Borough Council has adopted a Community Infrastructure Levy charging schedule; not every council has. Where it applies, it can be charged on a new home of any size. A self-build exemption exists for people building a home to live in, but it must be claimed before work starts, so we check the position at design stage.

How close can a new house be to my own in Aberdare?

There’s no single national distance. Many councils use separation guides of around 21 metres between facing back windows and around 12 to 15 metres between a back window and a blank side wall, but the guidance used by Rhondda Cynon Taf County Borough Council decides. Window positions, ground levels, roof shape and screening all affect what is acceptable, which is why we survey before we design.
