Highbury Stadium Square Estate — Facade Measured Survey, Islington

Project Brief

Angell Surveys was appointed to carry out a detailed measured survey of the existing external elevations of the residential buildings forming part of Highbury Stadium Square Estate, Islington, London N5 1FH — the former Arsenal Football Club stadium converted to residential use. The survey was commissioned to support planned facade remediation works across the estate.

The scope covered the South, West and North blocks. The Grade II listed East Stand and basement areas were explicitly excluded from the survey requirement. Penthouse levels on all blocks were included within the survey scope.

The client required two separate deliverables: a full set of 2D AutoCAD DWG drawings and a 3D Revit 2022 model, both georeferenced to Ordnance Survey National Grid with levels related to Ordnance Datum (Newlyn).

Survey Scope

The survey captured all external elevation features relevant to the facade remediation design, including:

• Facade articulations — cornicing, quoins, string courses and projecting features
• All penetrations, outlets, recesses, reveals, soffits and returns
• Windows and doors with full frame, reveal and cill geometry
• Parapets, copings and cills
• Chimneys, fire escapes, balconies, walkways and balustrades
• Roof details and penthouse level features
• External material identification and annotation

All survey control was established on Ordnance Survey National Grid (OSGB36) with spot levels and contour annotations referenced to Ordnance Datum.

Deliverables

Output 1 — 2D AutoCAD DWG: A full set of elevation drawings produced at 1:1 scale in millimetres, with the coordinate origin set at 0,0. Each plan, elevation and section was supplied as a separate DWG file, cross-referenced to the estate block diagram. Spot levels and contour values were supplied as text annotations. All files were purged of redundant layers, blocks and styles. Drawings were delivered in AutoCAD DWG and PDF format.

Output 2 — 3D Revit 2022: A full three-dimensional survey model of the external elevations of the South, West and North blocks, produced in Revit 2022. The model incorporated all facade geometry captured during the survey, georeferenced to the project coordinate system.
