Planning promotion for garden plots in Cardiff

If you’d rather find out what the market pays for your Cardiff garden plot once it has planning than accept a fixed figure today, planning promotion is built for that. We pay to seek permission, an agreed agent markets the plot if it is granted, and you approve the buyer and the terms.

A minimum price agreed at the start means the plot can’t be sold below it without your written consent. Sale costs, our capped planning costs and our fee are deducted on completion, and the balance goes to you through your solicitor. Value depends on the plot’s location, size, access and permission, so we won’t guess a figure before the appraisal.

The local picture in Cardiff

At noon on 21 March the sun over Cardiff sits about 39° 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. Cardiff 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.

Noon sun in Cardiff on 21 March sits about 39° 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.

How we’d take it forward in Cardiff

Here’s what happens after you contact us about a garden in Cardiff. We start with a free desktop appraisal of your title plan, access and the policies in the council’s Local Development Plan (LDP), then talk it through with you. If it looks viable, we visit. If promotion fits, we send heads of terms, and your solicitor reviews them, with reasonable legal fees covered up to an agreed cap, before anything is signed.

  1. 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.

  2. Agreement signed

    Your solicitor and ours turn the heads of terms into a promotion agreement. It’s usually protected by an entry on your title, and if your house is mortgaged, your lender is asked to consent early.

  3. 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.

  4. Completion and payout

    On completion, sale costs, our capped planning costs and our fee come out of the proceeds in the order the agreement sets. The balance is paid to you through your solicitor.

Worth checking early

  • Planning may be refused. You keep your land and owe nothing for planning, but the months spent can’t be given back.
  • You can’t sell the plot to anyone else while the agreement runs, so the term length matters.
  • Promotion takes longer than a straight sale: planning, then marketing, then completion, and each stage can run on.

Your questions, answered for Cardiff

Who decides a planning application for a garden plot in Cardiff?

Cardiff Council decides it, using the council’s Local Development Plan (LDP) and national policy in PPW. Nobody can promise the outcome. Under promotion we prepare and submit the application at our cost and deal with the council’s questions, but the decision is the council’s, and it can grant, refuse or ask for changes.

How long does planning promotion take for a garden in Cardiff?

It usually takes longer than a straight sale. Design and surveys often take a few months, then Cardiff 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.

Can neighbours in Cardiff 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.

Is planning promotion available for a single garden in Cardiff?

Yes, if the plot is suitable, though promotion is more usual on larger sites. On one modest garden, the fixed costs of planning, legal work and marketing take a bigger share of the sale. After the free appraisal we’ll tell you whether promotion, a sale subject to planning or an option suits your garden best.
