Working from a topographical survey which the Client had undertaken by a third party, I lifted the spot levels up to create a 3D wireframe model of the contours of the site in Sketchup. This model would prove useful in determining where the proposals would sit on site and how the levels, where they vary dramatically adjacent the existing building, would work regarding the regrading of the land.
3D VISUAL - SHADING
The shading on the wireframe model shows the detail of the variation in ground levels more clearly.
3D MODEL - EXISTING HOUSE
I modelled the existing house from the set of measured survey plans which I undertook myself on site. I created this separately to the contour plan and brought it in to the overall model as a group.
TOPOGRAPHICAL SITE WITH HOUSE - AS EXISTING
Once I brought the existing house in to the model, I cleared the wireframe from the image and left just the lines which defined the edge of the driveway and the main drop in levels of the land outside the house. This clearly shows how the house sits within the existing landscape.
3D MODEL - PROPOSALS & LEVEL INFORMATION
The 3D model clearly shows how the proposal sits within the landscape and how the land will need to be adjusted to suit the scheme design.
FINISHED CONCEPT 3D MODEL
Once I had developed the scheme design based on my plans and the topographical levels provided, I added an effect to the model to soften it and make it appear 'sketchy'. The idea is to use the model to present as a concept to the Client before adding further details as may be required.
