Shadow Diagrams for
Manchester Planning Applications.
shadow diagrams for planning applications across Manchester and all Greater Manchester boroughs — from a Chorlton rear extension to a high-rise scheme near Deansgate Square. Fixed prices from £280. First draft in 48 hours. Full BRE 209 daylight & sunlight assessments (VSC/APSH/NSL) join the Manchester service line in late August 2026 — enquire to reserve a slot.
We read your council's validation checklist before we model a single shadow
Daylight, sunlight and shadow evidence that survives Manchester's toughest planning officers.
Manchester City Council applies BRE 209 across some of the country's fastest-changing planning contexts — city centre regeneration zones like NOMA, Ancoats and Spinningfields, MediaCityUK across the Salford border, and dense suburban infill throughout the ten Greater Manchester boroughs. We build our shadow diagrams to survive scrutiny the first time: correct reference dates, a full BRE 209 methodology statement, and geometry matched exactly to your submitted drawings.
Everything your Manchester planning application requires
One fixed price. No hidden extras. No surprise charges for additional time-points or revision rounds.
Shadow Footprints at Required Dates
Shadow diagrams at the equinox (21 March / 21 September) and winter solstice (21 December) at the times your council requires — typically 9am, 12pm and 3pm, or 8am–4pm hourly for larger schemes. Existing and proposed shadows distinguished by colour.
BRE 209 Methodology Statement
Written methodology note confirming software and sun-path model, OS grid reference, applicable BRE 209 criteria, reference dates and times, and true north basis. Ready to include in your Design and Access Statement.
VSC / APSH / NSL Analysis
Where required by your council, full Vertical Sky Component, Annual Probable Sunlight Hours and No Sky Line calculations for affected neighbouring windows, with results and interpretation against BR 209 (2022) thresholds for each window assessed.
True North & OS-Accurate Geometry
True north confirmed against OS map data. Site boundaries, neighbouring footprints and street alignment verified against your planning drawings — critical in Manchester's tight terraced streets and high-density city centre plots where a few degrees changes the outcome.
Print-Ready PDF + DWG / ArchiCAD Source
A1/A3 print-ready PDF formatted for planning portal upload, plus full DWG and/or ArchiCAD source files. No locked files, no watermarks.
One Free Planning Amendment
If your council's planning officer requests amended diagrams as a Further Information request, one amendment round is included at no additional charge — updated and re-issued within 48 hours.
The key thresholds Manchester planning officers check against
BRE 209 (Site Layout Planning for Daylight and Sunlight) is the guidance document Manchester boroughs use to assess daylight and sunlight impacts. For full VSC/APSH/NSL calculations with window-by-window interpretation against the applicable BR 209 (2022) criteria, see our Daylight & Sunlight Assessment Manchester service — here's the summary that matters for a standard shadow diagram.
27% VSC or more generally indicates adequate skylight. A reduction to below 0.8 times the former value may be considered noticeable.
City centre regeneration zones like NOMA, Ancoats and Spinningfields are frequently assessed with contextual flexibility given the higher density Manchester City Council actively encourages there — we confirm the applicable approach before modelling.
Main living room windows facing within 90° of south should receive at least 25% of annual probable sunlight hours, including at least 5% in winter (21 September–21 March).
Assessed per window for every affected neighbouring property within the study area.
Divides a room's working plane into areas that can and can't see the sky. If the daylit area falls below 0.8 times its former value, occupants typically notice the change.
BRE 209 §2.3BRE 209 thresholds are guidance, not mandatory standards. Manchester boroughs apply them with varying degrees of contextual flexibility. We confirm the applicable approach with your council before commencing.
