Residential architecture, from site to client-ready.

Place the house on its actual lot, test directions while they're still cheap to change, and show the client something they can walk through.

Keep working how you work.

Bring the model in from Revit, Archicad, SketchUp, or IFC. Harth works alongside your CAD, not instead of it. Your CAD stays where the building becomes precise.

How it works

  • 01. Bring in the model.

    Import from Revit, Archicad, SketchUp, or IFC, with elements and coordinates intact.

  • 02. Place it on the site.

    Real terrain at real coordinates, with the neighboring buildings around it and the boundary traced from the map.

  • 03. Design and check.

    Move the massing, fit out the plan, run the sun study, check the numbers against real geometry.

  • 04. Share with client.

    Renders and a walkthrough off the model, collected into a board. Share a highly curated link, not the workspace.

From the site to the conversation that decides it.

The site, before anything is drawn.

The site, before anything is drawn.

Explore options until it feels like home. Visualize any space in minutes. See as many different finishes of your space as you can think of. Swap the moodboard for reality.

Directions you can test cheaply

Directions you can test cheaply

Move walls, shift the massing, try the other orientation. Explore more while a change still costs a conversation instead of a redraw.

Sun on the actual site

Sun on the actual site

Set the month and the time and look at the shadows – on this site, at this latitude, with the neighbors casting theirs too.

Where the plan meets daily life

Where the plan meets daily life

Circulation, daylight, kitchen and bathroom layouts, accessible routes. Agents that know what makes a house work, not just what fits.

Clients who decide early

Clients who decide early

Most clients build once. Renders and a walkthrough off the real model let them react early, while the ideas are still open.

Residential, whatever the type.

Frequently asked questions

You can build walls, slabs, and stories directly, or start from a 3D template. Most practices model in CAD and bring it in.
