Development potential — buildable envelope and site capacity
Parcela works out the maximum buildable envelope for your plot from planning policy, building lines, boundary setbacks and surrounding context — and shows it in 3D on the plot’s real terrain, so you can read the development potential before you commit.
Assess your plot’s potential →How to assess a plot’s development potential
- 1Pick the plot. Parcela loads the plot extent, the planning parameters that apply and data on the terrain and surroundings.
- 2Build the envelope. The app computes the maximum massing consistent with height limits, density, building lines and required boundary setbacks.
- 3Estimate capacity. You get the indicative floor area, storey count and unit potential — shown in 3D and in numbers — so the development potential is concrete, not guesswork.
From envelope to scenarios
The envelope is the starting point. From it, Parcela proposes concrete A/B/C development scenarios — for example a single dwelling, a small terrace or a flatted block — each with a floor-area schedule and an early appraisal.
Frequently asked questions
What is site capacity?
It is the maximum amount of floorspace — or number of units — that can realistically be delivered on a plot within the applicable planning policy and constraints. It feeds directly into what the land is worth to a developer or self-builder.
How does Parcela work out the buildable envelope?
From building lines, maximum height, density and coverage indicated by planning policy, plus the boundary setbacks required around the plot — all rendered in 3D on a digital terrain model.
Is the envelope a guarantee of what will be consented?
No. It is an indicative, policy-led massing to gauge potential early. The consentable scheme depends on detailed design, amenity, daylight and sunlight, highways and the planning judgement — for which you need professional advice.
