When architecture, customer experience and the business model are designed together, the space works for the business every day.

Case study · 3DNA

From a PDF plan to an interactive digital project.

See how we turn architectural documentation into a navigable 3D model with information on spaces, equipment, indicative costs and estimated energy use.

  1. Anonymised floor plan of a sports centre: fitness hall, changing rooms, spa, toilets and reception.

    01 — You send

    You send us your plans.

    We start from PDF plans, architectural documentation and whatever information is available about your space.

  2. 02 — We create

    We turn them into a digital space.

    We rebuild the geometry, organise the spaces and add design, materials and equipment.

  3. Perspective view of the 3D model of the building with the equipped fitness hall.

    03 — You receive

    You receive an interactive presentation.

    Explore the building, check every space and share a clear picture of the project with your team, clients or investors.

Multipurpose hall — from plan to experience

Three views of the same hall, with the same interior design and the same layout: from the architectural plan to the experience at eye level.

  2. 02 — Interior view

    The same hall at eye level: materials, lighting and equipment as they will be experienced.

  3. 03 — Virtual walkthrough

    A short cinematic walkthrough of the same space to present the project before construction.

Visualisations of the proposed design; not photographs of a built space.
