Bluesky 3D building models aid designs for London residences

London building-design agency DCSK is using 3D building models from Bluesky to inform the design of high-profile urban residential developments.

Derived from the most up-to-date and accurate aerial photography, the Bluesky 3D models allow DCSK to place a design within its real-world context, consider sensitive view and vantage points, and communicate ideas to clients, planning authorities and the public.

DCSK has used a number of models from Bluesky, including a detailed representation of central Birmingham for the design of a 24-storey student accommodation on Lancaster Street.

“We have always had to consider how a design sits within the existing cityscape and how it will interact with the buildings and infrastructure that surround it,” said James Khamsi, Director of DCSK. “Before geographically accurate computer representations, such as the Bluesky 3D models, were available and affordable, we relied on a combination of site photographs and traditional 2D maps. This was a crude workflow that raised potential concerns about the currency and accuracy of information that was informing both the design and resulting planning permissions.”

DCSK is using 3D models from Bluesky for projects such as Curzon Circle Student Accommodation and others.Photogrammetrically derived from stereoscopic aerial photography, the Bluesky models are fully rendered and are provided as either wireframe or block models in a format suitable for use in both CAD and GIS software.

All Bluesky 3D models are supplied with a digital terrain model (DTM) depicting the topography of the underlying surface.

DCSK imports the Bluesky data into its 3D modelling software Rhino, where it is used to create a background layer for the design. The development site is isolated, and this data removed from the background layer, allowing for the detailed design to be dropped in. The proposed development can then be viewed and analyzed in its real-world context with detailed assessments of access ways and viewpoints, for example.

“The Bluesky models allow us to inhabit the site and experience the design as if we were there,” said Khamsi. “We can explore potential sensitivities, and, as the models are agile, we can massage the design exploring different options without leaving the office. The Bluesky models are also intuitive and therefore easy to interpret allowing us to communicate complex design ideas.”
