3d modelling right to light
Accurate 3D modelling for Right to Light turns guesswork into clear, court-standard evidence. We build verified context and receptor models, quantify window-by-window injury, and test targeted mitigations, so you keep viable floorspace and reduce the risk of injunctions or costly redesigns.
What is 3D Modelling for Right to Light?
It’s the creation of a scaled digital model of the existing context, receptors (qualifying windows) and proposed massing to assess whether neighbours retain sufficient light under the Right to Light legal test. Unlike a quick desktop screen, 3D modelling delivers quantified, window-level results suitable for negotiation, insurance and (if needed) litigation strategy.

At-a-glance comparison
| Topic | Desktop Feasibility | 3D Modelling (Right to Light) | Full Right to Light Report |
|---|---|---|---|
| Purpose | Early risk screen | Accurate window-level analysis & design iteration | Court-standard evidence for negotiation/insurance |
| Outputs | Risk grading, hotspots, headline tweaks | 3D model, injury schedules, quantified mitigations | Formal report + appendices, negotiation strategy |
| Use cases | RIBA 0–2, pre-app, site acquisition | Tight sites, vertical additions, neighbour engagement | Insurance, settlement, potential dispute |
| Turnaround (typical) | ~2–5 working days | ~1–2 weeks (scale-dependent) | ~1–3 weeks (scope-dependent) |
Why it matters
- Precision: Window-level injury analysis rather than coarse assumptions.
- Design control: Test setbacks, step-backs, chamfers, cut-backs, lightwells and see the impact before you commit.
- Negotiation power: Clear schedules and visuals to support without-prejudice offers.
- Insurance-ready: Outputs aligned to what underwriters expect to see.
- Programme safety: Avoid late surprises that force re-design or trigger dispute.

Got questions about right to light in London?
Below are answers to the most common right to light questions we receive from London homeowners, architects and developers covering law, process, fees and what to send us.
Yes. BRE assesses planning amenity (VSC/NSL/APSH/internal daylight). Right to Light models the legal easement to “sufficient light” and identifies injury.
When the site is tight, neighbours are sensitive, or you’re preparing for engagement/insurance and need quantified, window-level evidence.
BRE outcomes help the planning narrative, but RoL is decided on the legal test of sufficient light. Treat them as parallel workstreams.
Existing/proposed plans, sections, elevations, storey heights and roof forms. DWG ideal; scaled PDFs acceptable.
Often. Setbacks, step-backs, chamfers, local height trims and lightwells targeted at worst receptors provide strong gains with minimal GIA loss.
