A useful starting set.

Coverage matters more than a fixed number of files. The aim is to explain the layout, scale, heights and connections of the spaces you want included. Professional CAD, scanning and a walkthrough video are optional for this initial package.

01 / A short project note.

• The property or project, its location and one review contact.
• The rooms, floors and outdoor areas to include.
• Whether the model shows an existing condition or a proposed design.
• Furnished, unfurnished or both, plus any features that need particular care.
• How you plan to share the presentation and the devices you want it to support.
• The dates of your sources and any known changes or missing information.

02 / A plan for every level.

A clear hand sketch is welcome. Label rooms, entrances, doors, windows, stairs, fixed kitchen and bathroom fittings, and any terraces or courtyards in scope. Show which spaces connect and use the same labels for your photographs.

If you have a dimensioned plan, send an uncropped original with the measurements visible. Otherwise, measure each room's inside length and width. Add wall lengths for alcoves or irregular areas and mark opening positions from a named corner where needed.

03 / Dimensions that explain the space.

• A horizontal scale source in two directions for each level. Total floor area alone is insufficient.
• Ceiling heights for each distinct height zone, including lower or sloped areas.
• The size and direction of any split level, threshold step or floor-height change.
• For stairs: destinations, riser count, total rise, clear width and flight or landing arrangement.
• Clear widths or heights at narrow openings and important walking connections.
• Dimensions, boundaries, access and level changes for outdoor areas in scope.

Write the units and identify each measurement as measured, printed on a drawing or estimated. Mark where it was taken on the plan or a photograph. Do not assume a door, bed or tile is a standard size.

04 / Photographs with enough coverage.

Start with two wide photographs from opposite corners or ends of each simple room. Move to a different position for the second view. Add photographs wherever these leave a wall, opening, floor or ceiling junction, or major fixed fitting hidden.

• Small bathrooms, closets and utility rooms: a doorway overview and a reverse or side view where accessible.
• Hallways and room connections: views that show both ends or sides and make the destination clear.
• Kitchens and bathrooms: clear contextual views of the main fixed fittings.
• Stairs: views from the top and bottom, with extra coverage for hidden turns and landings.
• Terraces and courtyards: a view looking outward and another looking back toward the property.

Use the normal 1× phone camera when possible, keep corners and frames clear, and include floor and ceiling junctions. Send original full-resolution files, grouped by room. Keep edited marketing images and different source dates separate.

For a property that has not been built.

Approved dimensioned drawings replace photographs and measurements of spaces that do not yet exist. Include level and ceiling information, elevations or sections for openings and major fixed fittings, and labeled finish or product references. Reference photographs explain appearance; they do not establish future dimensions.
