What shapes a plot in Portishead
A measured survey in Portishead records the plot exactly: boundaries, levels, trees, drains, and the positions and heights of neighbouring windows. It is the base for everything else. From it we can plot the shadow a two-storey eaves line would cast, roughly 6.3 m at noon on 21 March when the sun is near 39° here, and the distances between the new home and the houses around it. North Somerset Council will expect the application drawings to be accurate to a survey like this.
From first call to decision
Getting a straight answer about a garden plot in Portishead costs nothing at the first stage. Send us a few photos and a rough idea of the plot, or call, and we’ll check it from the desk. If it’s not worth pursuing, we’ll say so and explain why. If it is, we’ll set out the next steps and their cost in writing.
Free plot appraisal
A desktop look at your plot, access, title plan and the planning picture, plus a conversation about what you want. If it looks viable we visit. There’s no cost and no obligation at this stage.
Survey and constraints check
A measured survey of the plot and its surroundings, then a check of the title, services, trees, flood risk and heritage designations, so the design starts from facts rather than guesses.
Access and capacity study
We test each workable route in and the number, size and position of homes the plot could hold, against separation distances, garden space, parking, bins and daylight for neighbours.
Concept designs and pre-application
Sketch layouts and simple elevations for the strongest options. Where it will help, we take one to the council for pre-application advice before anything is submitted.
Worth checking early
- Some ecology surveys can only be done at certain times of year, which can affect the programme.
- Pre-application advice is not binding, and the council’s decision on a formal application can still differ.
- A feasibility study can end in a no; finding that out early costs far less than a refused application.
Portishead: questions to ask
How much does a feasibility study cost in Portishead?
It depends on the plot. A simple garden with a clear drive needs less work than one with protected trees, a flood zone or a complicated title. The first appraisal is free. After that we set out the scope and the price in writing, and you choose whether to go ahead before anything is commissioned.
Is my Portishead garden in a flood zone or conservation area?
Both are public information. Flood zones are shown on the flood maps for planning in England, and North Somerset Council publishes its conservation area boundaries and the listed buildings in its area. We check these as part of the free appraisal, along with Tree Preservation Orders, because each one changes what a scheme needs to show.
Do I have to use you for planning after a feasibility study in Portishead?
No. The survey, report and concept designs are yours to use as you choose. You can take the scheme forward with us, through our planning permission or design and build services, or sell or partner on the plot with us, or use another firm. We would rather you made the decision that suits you.
Can you check the title deeds on my Portishead property?
Yes. We obtain the title register and title plan from HM Land Registry and read them for restrictive covenants, rights of way, easements and any mortgage charge. If something needs a legal opinion, we flag it so your solicitor can advise. Title issues are far better found during feasibility than halfway through a planning application or a sale.
