How Much Does a House Extension Visualisation Cost?

How much does a house extension visualisation cost? House extension CGI costs in the UK vary with project complexity, number of camera positions, and the level of contextual detail required. A single photoreal exterior image of a straightforward single-storey rear extension typically costs between £350 and £600 from a UK visualisation studio. This covers the 3D model, materials, lighting, and one revision round.

A two-storey or wrap-around extension requiring two or three camera angles runs from £600 to £1,200. The additional cost reflects the extra modelling time needed for a more complex roof form and the effort of showing the scheme from multiple sides. Where a verified view is needed for a conservation area or listed building setting, surveying and composite work adds further cost, often bringing the total to £1,500 or more per verified viewpoint.

Interior visualisation of the new extension space is priced separately from the exterior, usually £300 to £500 per room depending on the complexity of the fitout shown. Fees from a dedicated UK house extension visualisation studio tend to be lower than those bundled into an architect's full fee because the visualisation is the studio's core service rather than a side offering. Turnaround is typically five to ten working days from receipt of drawings.

When comparing quotes, confirm what is included: the number of camera positions, revision rounds, and the output format (typically TIFF or high-resolution JPEG at A2 size or larger for planning submission). A quote that looks cheaper but limits revisions to one round can cost more in the end if the planning officer requests changes to materials or viewpoints after submission.

For loft conversion visualisations running alongside an extension scheme, combining both into a single brief usually reduces the total cost compared to two separate commissions.
