Seymour Leisure Centre, London Case Study

Seymour Leisure Centre is a Grade II listed building designed by the council architect Kenneth Cross and built in the early 1930’s to an art-deco design. The facilities include a 100-station gym, 30 metres swimming pool, climbing wall, sports hall, etc.

Our client was undertaking an improvement project for the sports and leisure facilities of the building, including a new home for Marylebone Library, all while maintaining its distinctive architectural features.


  • Laser Scanner RTC360
  • Leica GNSS Receiver GS14
  • Leica Total Station TS16


  • Site time: 3 days
  • Modelling time: 45 days

What we did

ASES was requested to provide a LOD300 3D Revit model to include all the architectural and structural elements of the building and its surroundings. The model was referenced as part of an extensive refurbishment of the leisure centre facilities and services.

The final model would become a shared file between all disciplines involved in the project: architects, structural engineers, interior designers, etc.

The survey was carried out using a combination of laser scanner and total station technologies. Leica Scanner RTC360 was used to capture the three-dimensional geometry of the building while a network of control points was installed and coordinated to the UK Ordnance Survey national grid using a total station Leica TS16.

The 3D scans were registered in Leica Cyclone processing software and the point cloud exported in Recap (.rcp) format.

The final product was a full 3D Revit model of the building carried out to a high detail level internally and externally.


The leisure centre and all its facilities were still in use which presented a challenge to the survey team having to accurately coordinate various activities timetables ensuring that areas were free of traffic during the survey.

Due to the size of the model collaborative effort was required to achieve deadlines on time backed up by extensive QA procedures.
