Sketchup Model for a Planning Application in Croydon Borough

We are pleased to present a series of perspective views created in support of a planning application in the London Borough of Croydon. The scenes show ground level views of a proposal for new homes on a sloping site in South London.

Aerial views also show the new proposal in relation to an earlier application for the site and demonstrate how the scheme has responded to earlier reasons for refusal.

Like earlier modelling projects by Studio 425, the images are based on a combination of topographic survey data and the project architects’ proposed drawings. The relationship of the new building with its neighbours was key to the planning application and the view points of the eye level perspectives were chosen to show how the buildings would sit comfortably side by side.

The dramatic slope across the site is easily represented through the use of 3D modelling, whereas 2D elevations, which lack perspective, can cause confusion about relative heights and distances between buildings.

The images are based on topographic survey data, that was incorporated into a Sketchup model of the surrounding townscape. The existing roads, bridges and buildings were them modelled in 3D alongside a virtual model of the proposed new buildings. Views were then taken from an eye-level perspective of key parts of the model, including the approach to the neighbouring church spire and a footbridge over a river that runs adjacent to the planning application site.

The views offer dimensional accuracy, meaning that the relative heights of spaces and buildings within the views are all based on verifiable data. However, unlike verified views, which offer accurate rendering of materials, these Sketchup generated views use a restricted palette of notional materials for solid and transparent materials.

This simple approach helps to focus the conversation about the design onto the issues of privacy and massing, allowing materials and detailing to be addressed (hopefully) once planning permission is granted.
