Marylebone is characterised by georgian terraces, edwardian mansion blocks, concentrated across W1U, W1G, W1H in the
Marylebone area. Marylebone is not uniform, but the georgian terraces recurs often enough across W1U, W1G, W1H that the structural pattern is predictable once measured. For a typical Marylebone house, georgian roofs here are shallow and often behind a parapet, so the usable volume comes from a rear dormer set below the ridge rather than from the front slope. That detail drives the W1U construction sequence. The blocks around Marylebone High Street set the prevailing eaves and ridge lines, and Westminster City Council officers reference that rhythm when assessing height and massing on a Marylebone street.
Digging down in Marylebone runs into policy: Westminster basement policy restricts to single-storey, typically under 50% of rear garden footprint; lightwells and rooflights strictly controlled in conservation areas. Where the project also touches building regulations drawings for W1U properties or house extension drawings, the same measured survey of the Marylebone property carries across — you pay for the survey once, not per application.
What the Marylebone drawing pack contains
For a W1U, W1G, W1H address the deliverables are fixed, not open-ended.
- existing roof plan and section for the Marylebone property
- proposed dormer elevations
- volume calculation sheet
- staircase and head-height sections
- structural steel layout
Streets and landmarks we survey around Marylebone
- Cavendish Square — roof profiles that set the ridge datum Westminster City Council measures a Cavendish Square dormer against.
- Marylebone High Street — front-to-back level changes that drive the Marylebone High Street section drawings.
- Portland Place — gardens deep enough for the 8 weeks householder route on a Portland Place plot.
- Wigmore Street — side returns where the 45-degree amenity test decides how far a Wigmore Street extension goes.
- Oxford Street — terraced rear elevations — the Oxford Street party wall position is drawn first.
- Lisson Grove — side returns where the 45-degree amenity test decides how far a Lisson Grove extension goes.
- Marylebone Lane — frontages visible from the highway, so Belgravia materials detail governs the Marylebone Lane elevation.
- Regent's Park — gardens deep enough for the 8 weeks householder route on a Regent's Park plot.
- Marylebone High Street — Westminster City Council weighs W1U sightlines to it in the character assessment.
- Wigmore Hall — schemes visible from it get closer scrutiny in Westminster.
- Sylvia Young Theatre School — schemes in view of it attract closer officer scrutiny.
- St Marylebone Parish Church — schemes in view of it attract closer officer scrutiny.
- St Marylebone Church — schemes visible from it get closer scrutiny in Westminster.
- London Business School — proposals in its setting are drawn with the Marylebone context elevation.
Getting to a Marylebone survey
Surveyors travel to W1U addresses from the studio; the nearest stations are
Marylebone station, Baker Street, Bond Street, Edgware Road. Appointments are booked in Marylebone on weekdays and Saturdays,
and the measured survey of a standard georgian terraces takes two to three hours.
Where Marylebone sits
Marylebone lies 2 miles (3.2 km) north-west of Charing Cross, on Ordnance Survey grid reference TQ285815. A W1U submission is checked against exactly that location before Westminster City Council will register it. Source.
Practical detail for a Marylebone submission: Marylebone is served by Marylebone station and Baker Street and Bond Street and Edgware Road; the postal town here is LONDON; dialling code 020; listed fabric nearby includes Grade II Paul McCartney. Site plans are drawn to the address as Westminster City Council holds it.
Marylebone postcode coverage
The districts we work in here: W1U (Marylebone), which Marylebone holds on its own; W1G (Harley Street / Marylebone), which Marylebone holds on its own; W1H (Marylebone), which Marylebone holds on its own. Which side of the W1U line a property sits on changes the Westminster constraints that apply.
