Presenting Architecture in Photorealistic 3D: Beyond Renders and Photography

Every architecture practice has a portfolio of CGI renders. Clients have learned to discount them — renders flatter projects, hide constraints, and present an idealised version of a space that rarely matches the built reality.

A Gaussian Splat of a completed project offers something categorically different: irrefutable evidence of what you have actually built, in a format that lets prospective clients explore it for themselves.

When pitching for a new commission, the most persuasive material you can present is a genuine record of comparable work — not a photograph that flatters, not a render that promises, but a freely explorable 3D space that lets a client understand your quality and approach with their own eyes.

Spatium captures of completed projects integrate directly into pitch decks, practice websites, and client presentations. The viewer runs in any browser — no download, no special hardware.

For interior designers and fit-out contractors, a Gaussian Splat serves simultaneously as a portfolio asset, a client handover record, and a marketing tool. The precision of the capture records material choices, lighting conditions, and spatial compositions in a way that photography cannot — giving future clients the ability to see exactly how a finished project looks from every angle.

Gaussian Splatting is most powerful when used to document the built. For unbuilt projects, conventional CGI rendering remains appropriate. A compelling architectural practice website or pitch uses both — renders for the proposed, Splats for the completed — establishing a chain of credibility from promise to delivery.

Spatium can advise on how to structure this combination in client-facing materials.

Local planning authorities increasingly accept digital 3D records as part of listed building applications and change-of-use submissions. A Gaussian Splat of an existing space, produced prior to proposed alterations, serves as an accurate pre-works record that supports both the application and any future reinstatement requirement.
