Existing buildings, proposed schemes and surrounding context are brought together in a structured 3D model for the agreed planning or technical workflow.
CAD Services Studio coordinates architectural drawings, survey information and contextual data to create clear existing and proposed conditions. Models can be updated as the design develops and prepared for agreed downstream analysis.
The service provides technical modelling support. Architectural design responsibility, planning strategy and professional planning judgement remain with the appointed project team.

Urban Context Modelling
Complex survey information interpreted and prepared as accurate urban geometry for coordinated planning and downstream technical use.
What information is needed to prepare a planning model?
The project normally requires existing survey information, proposed architectural drawings, relevant context data, the required model extent and a clear description of its intended use.
Can existing and proposed conditions be modelled separately?
Yes. Existing and proposed geometry can be organised as separate coordinated conditions so that design changes and technical comparisons can be managed clearly.
Can the model be updated when the scheme changes?
Yes. Design revisions can be incorporated by agreement, with the scope and programme reviewed against the scale of each change.
Can surrounding buildings and site context be included?
Yes. The required context extent and level of detail are agreed according to the planning, visual or analytical purpose of the model.
Can the geometry be prepared for environmental analysis?
Yes. Where included in the agreed scope, the geometry can be coordinated and prepared for downstream Daylight, Sunlight, SHOG or Rights of Light workflows.
Does this service include planning advice?
No. CAD Services Studio provides technical modelling and drawing support. Planning strategy, policy interpretation and professional planning advice remain with the appointed planning team.
