Blackwood: light, access and policy
Wherever your house sits across NP12, 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 Caerphilly 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.
From first call to decision
Getting started in Blackwood takes one step from you: send your address and a few photos of the garden, or call us. We check the title plan, access and planning constraints from our desk, then talk the plot through. If it looks viable we arrange a visit, discuss whether you want to sell, let or keep the new home, and set out the survey and design stage in writing before you commit.
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.
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.
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.
Written quote and build
Once design and survey are complete you get a written quote. The build runs in stages — access and groundworks, foundations, frame and roof, fit-out and external works — with inspections at each key point.
Worth checking early
- A build next door means months of noise, deliveries and contractors near your home; good planning reduces the disruption but doesn’t remove it.
- You fund the build and carry the cost risk; ground conditions, sewer diversions or supply upgrades found later can move the price.
- Building and selling a new home can change your tax position compared with selling only your house; take advice from a tax adviser first.
Your questions, answered for Blackwood
Do you visit gardens in Blackwood before giving advice?
We start with a desk review of the title plan, access, constraints and planning policy, then talk the plot through with you. If it looks viable, we arrange a site visit to see the access, levels, trees and neighbouring windows for ourselves. The appraisal is free and carries no obligation.
Can I build a house in my garden in Blackwood and keep the land?
Yes. On our design and build route you remain the owner while we design the home, apply to Caerphilly County Borough Council for planning, deal with Building Regulations and build it. The finished house can be sold, let or kept for family. Whether your plot can take a house depends on access, space, neighbours and local policy, and the decision rests with the council.
Will I pay Community Infrastructure Levy on a new home in Blackwood?
Only if Caerphilly 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 long does planning take for a new home in a Blackwood garden?
The statutory period for deciding a minor application, such as a single new home, is 8 weeks from the date the council receives a valid application, in both England and Wales. In practice many applications take longer, and the council may ask you to agree an extension in writing. Surveys and design before submission add time, and conditions may need approving afterwards.
