Building in a large rear garden in Blackwood

Not every long garden in Blackwood should be built on, and we’d rather tell you that early. A deep plot with a narrow side gap, a steep slope or a big protected tree may be better left as garden. Others have enough depth and a usable way in to take a well-placed new home.

Our free appraisal sorts one from the other. If yours works, you can part with the land while staying in your house, agree an option or a conditional sale, or keep it and have us design and build. If it doesn’t, you’ve lost nothing but a conversation.

Before you decide in Blackwood

Overshadowing is often the deciding issue in a long garden. At midday on 21 March the sun in Blackwood stands about 38° above the horizon, so a typical two-storey eaves line throws a shadow of roughly 6.3 m. In midwinter the noon sun is only about 15° up and shadows stretch around three times as far.

That’s why the gap between a new home and neighbouring gardens matters, and why a lower roof, or a home set further from the boundary, can make a scheme acceptable. We check the shadows on your actual plot rather than relying on rules of thumb.

Noon sun in Blackwood 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 Blackwood

Here’s what happens after you get in touch about a garden in Blackwood. We look at maps, the title plan and nearby planning history, then call you to talk it through. If the plot looks viable we visit, measure up and check access, levels and trees. You then get a plain summary of what could fit and the routes open to you, with no obligation to take any of them.

  1. Free plot appraisal

    We look at your garden using maps, the title plan and the planning history around you, then talk it through with you. If it looks workable we arrange a site visit. There’s no cost and no obligation.

  2. Measure and test the layout

    We check depth, the width of the way in, levels, trees, drains and what lies behind, then sketch what could realistically fit: one home, two, or nothing worth pursuing, before anyone pays for an application.

  3. Choose your route

    You decide whether to sell the plot outright, sell subject to planning, grant an option, team up with neighbours, or keep the land and have us design, get planning for and build a home on it.

  4. Sale or build

    If you sell, your solicitor handles the transfer of part and your lender’s release of the plot. If you build, we give a written quote after design and survey, then build and hand over the new home.

Worth checking early

  • Neighbours are consulted and may object. The council decides, and a carefully designed scheme can still be refused.
  • A shorter garden changes how your own house feels to live in and may affect what it is worth.
  • Cars passing beside your house to reach the new home bring noise and headlights; screening helps but doesn’t remove it.

Your questions, answered for Blackwood

How long does planning take for a garden home in Blackwood?

It varies. Small schemes often take a few months from submission to decision, and longer if surveys, amendments or extra consultation are needed. Pre-application advice and early surveys add time at the start but can save time later. We won’t promise a date, because the council sets the pace.

Can I build a house in my back garden in Blackwood?

Possibly, if the garden is deep enough, has a safe way in and a new home wouldn’t harm the neighbours or the character of the street. A new separate home always needs planning permission, and Caerphilly County Borough Council makes the decision. A free appraisal will tell you whether your garden is worth taking further.

Who decides planning for a home in a Blackwood back garden?

Caerphilly County Borough Council decides, using the council’s Local Development Plan (LDP), national policy and any local design guidance. It consults neighbours and other bodies before reaching a decision. We prepare the application and deal with the planning officer, but the outcome is always the council’s call.

Does it cost anything to have my Blackwood garden looked at?

No. The garden plot appraisal is free and carries no obligation. It starts with a desktop check and a conversation, and we arrange a site visit if your garden looks viable. You only commit to anything once you’ve chosen a route and seen the terms in writing.
