Before you decide in Harpenden
At noon on 21 March the sun over Harpenden sits about 38° above the horizon, so a two-storey eaves line around 5 m high casts a shadow of roughly 6.4 m. By 21 December, with the sun at about 15°, that shadow is far longer. St Albans City and District 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.
From first call to decision
Here’s what happens after you contact us about a garden in Harpenden. We start with a free desktop appraisal of your title plan, access and the policies in the council’s Local Plan, 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.
Free plot appraisal
We check your title plan, access, the surrounding gardens and the policies in the council’s Local Plan 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.
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.
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.
Worth checking early
- 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.
- On a single small plot, fixed costs and our fee take a bigger share of the sale price than on a larger site.
Harpenden: questions to ask
How is a promoted garden plot in Harpenden 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.
Do I pay anything upfront for planning promotion in Harpenden?
No. We fund the surveys, drawings and planning fees. Those costs are recovered from the sale proceeds, within a cap set in the heads of terms, only if a sale with planning happens. Your reasonable legal fees for the agreement are also covered up to an agreed cap.
Is planning promotion available for a single garden in Harpenden?
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.
Does a mortgage on my Harpenden home stop a planning promotion?
No, but your lender has to be involved. The lender’s charge covers the garden, so it must agree to release the plot before it’s sold, and some lenders want to approve the promotion agreement too. We raise this at the start so it doesn’t delay a sale later.
