As Built Survey in Westminster: Costs, Deliverables and Turnaround
Westminster is London's premier commercial and residential address — home to some of the capital's most significant property, from the Georgian terraces of Mayfair and Marylebone to the commercial towers of Victoria and the高端 residential stock of St John's Wood and Maida Vale. Commissioning an as built survey in Westminster requires understanding the exceptional documentation standards applied by one of the capital's most rigorous planning authorities.
This guide covers everything you need to know about commissioning a measured building survey in Westminster — including realistic costs, standard deliverables, and typical turnaround times.
Westminster's Property Landscape and Survey Requirements
Westminster's property stock is among the most varied and valuable in London. Survey requirements reflect this complexity.
Georgian and Victorian residential — Mayfair, Marylebone, Fitzrovia, and St John's Wood contain some of London's finest Georgian and Victorian residential property. These buildings often have complex geometries, high ceilings, original plasterwork, and historic fabric requiring careful measurement. For planning applications in Westminster's Conservation Areas, laser scanning is typically the appropriate method and RICS Level 3 accuracy is required.
Commercial and mixed-use — Victoria, Paddington, and the Strand contain significant commercial property where floor area measurement for letting and sale requires NIA and GIA calculations to RICS Code of Measurement Practice standards. Westminster's commercial market is among the most active in London and measured surveys for commercial transactions are a standard requirement.
Heritage and listed buildings — Westminster contains a high concentration of Grade I, Grade II*, and Grade II listed buildings. Any works to listed buildings require measured surveys to RICS Level 3 accuracy standard with detailed recording of architectural features. We have specific experience with Westminster's listed building requirements.
New build and major refurbishment — Major commercial and residential developments in Victoria, Paddington, and the surrounding area require measured surveys at design stage and as built surveys at practical completion. BIM coordination is commonly required by principal contractors on major schemes.
Development sites — The City of Westminster has significant redevelopment activity across several opportunity areas. As built surveys are required for existing buildings ahead of redevelopment and for new build handover at practical completion.
As Built Survey Costs in Westminster
Westminster's property market commands the highest prices in London — reflecting the complexity of surveying in the borough, the operational costs of working in central London, and the documentation standards required. Guide prices for Westminster (covering all W1, SW1, and NW postcodes in the City of Westminster):
| Property type | CAD drawings | CAD + BIM | |---|---|---| | 2-3 bed flat / townhouse | £800–£1,400 | £1,400–£2,500 | | 4-5 bed period property | £1,200–£2,200 | £2,000–£4,000 | | Small commercial unit | £1,000–£2,000 | £2,000–£4,500 | | Large commercial/listed | £2,500–£10,000+ | £6,000–£25,000+ |
These prices reflect the central London operating environment and the documentation standards required by Westminster Council. Parking, congestion, and access restrictions in central London are significant cost factors. For a specific fixed-fee quote, provide the property address, approximate floor area, and output format required. We respond within one working day.
What Is Delivered: Cad Drawings, Bim Models, and Point Cloud
Every as built survey in Westminster includes 2D CAD drawings as standard. Additional deliverables are available depending on your project requirements:
2D CAD drawings (DWG) Floor plans, sections, and elevations in AutoCAD 2018 format. Standard deliverable for Westminster Council planning applications, building control completion certificates, and contractor tender packages. PDF version included as standard.
Revit BIM models (LOD 300–350) 3D models from laser scan data for architects and developers working on new build or major refurbishment projects. Particularly relevant for major commercial schemes in Victoria, Paddington, and the West End where BIM coordination is required.
Point cloud data (RCP/RCS) Full-colour laser scan data for complex geometries, period properties with intricate detail, and projects requiring a digital twin for design coordination or FM purposes. Laser scanning is the appropriate method for Georgian and Victorian properties in Westminster's Conservation Areas and for all listed building surveys.
Area measurement schedules RICS-compliant NIA and GIA measurements for commercial property lettings and sales. Delivered to RICS Code of Measurement Practice 8th edition alongside the drawings.
