Before you decide in Blackwood
At noon on 21 March the sun over Blackwood sits about 38° above the horizon, so a two-storey eaves line around 5 m high casts a shadow of roughly 6.3 m. By 21 December, with the sun at about 15°, that shadow is far longer. Caerphilly County Borough Council will weigh how a new home affects daylight and sunlight to your house and the gardens next door.
Under promotion we test this before applying, because a refusal on overshadowing costs time even though it doesn’t cost you money. Moving the new home, lowering the eaves or turning the roof can make the difference.
How we’d take it forward in Blackwood
The first step for a Blackwood garden is a conversation and a desktop check, at no cost. We then send written heads of terms covering the term, minimum price, cost cap and fee. Once the agreement is signed, we commission surveys and drawings, take pre-application advice from Caerphilly County Borough Council where it helps, and submit the application. Marketing starts only after permission is granted.
Free plot appraisal
We check your title plan, access, the surrounding gardens and the policies in the council’s Local Development Plan (LDP) as a desktop exercise, then talk it through with you. If it looks viable, we visit. No cost and no obligation.
Heads of terms
We set out the deal in writing: the term, how our fee works, the cap on planning costs we can recover, the minimum price, the marketing approach and the cap on your reasonable legal fees that we cover.
We apply for planning
We commission the surveys and drawings, take pre-application advice where it helps, submit the application and deal with the council’s questions. You pay nothing at this stage, and the decision is the council’s.
Marketing and sale
With permission granted, the plot is marketed as the agreement sets out. You see the offers and approve the buyer, and the plot can’t be sold below the minimum price without your written consent.
Worth checking early
- On a single small plot, fixed costs and our fee take a bigger share of the sale price than on a larger site.
- You’ll live next to whatever is built, so the layout, windows and new boundary affect your house too.
- The plot’s price isn’t known until it’s marketed with permission; it depends on location, size, access and the permission itself.
Questions about garden plots in Blackwood
How long does planning promotion take for a garden in Blackwood?
It usually takes longer than a straight sale. Design and surveys often take a few months, then Caerphilly County Borough Council needs time to decide, and marketing and conveyancing follow. The council’s workload, extra reports and any appeal drive the timing, so we give a realistic range after the appraisal.
How is a promoted garden plot in Blackwood sold?
After permission, an agent agreed with you markets the plot to builders, developers and self-builders. You see the offers and approve the buyer. The plot can’t be sold below the agreed minimum price without your written consent, and any offer from us has to stand up against the open market.
Can you look at my garden in Blackwood before I commit to anything?
Yes. The plot appraisal is free and carries no obligation. We start with a desktop check of your title, access and the planning policies that apply, then talk it through with you. If the plot looks viable, we arrange a site visit before any heads of terms are drafted.
Can neighbours in Blackwood combine gardens for a planning promotion?
Yes, and promotion often works better that way. Adjoining gardens can share one access and allow a better layout. Each owner keeps their house, signs an agreement setting out how proceeds are shared, and takes advice from their own solicitor. We can appraise the combined land as one site first.
