Mixed-use block Saved

A mixed-use block on this corner: shops along the street, homes above, 8 floors on the corner and terraces stepping down to the park. About 8,500 m².

Here’s a first version from your sketch: 8,560 m², with 1,180 m² of shops on the street, 8 floors on the corner and three terraces stepping down to the park.

Pool house Saved

A family house like these: a cantilevered upper floor, timber and glass below, and a pool facing the garden. About 190 m².

Here’s a first version from your references: 194 m² over two floors, with a 5 m cantilever over the terrace and a 12 m pool facing the garden.

Garden flat Saved

Here’s our floor plan. Open up the kitchen, add an island and big glass doors to the garden. Warm materials, like the photo.

Done. The kitchen now opens into the living room, with a 2.5 m island and 4 m of glass doors to the garden. The floors are warm oak.

Read the case studies

Arkio feels playful and simple, but it enables serious immersive collaboration. Whether with clients, communities, or our own teams around the world, it helps us make better design decisions together.

Anna MytculVisualization Specialist, KPF London

It just works! Arkio seems designed to be used and is easy to learn.

Marius JablonskisDigital Transformation Leader, Norconsult

Being able to step inside the model together helps teams reach alignment faster and gives stakeholders a clearer understanding of the design.

Abby ColemanInnovation Extended Reality Specialist, IMEG

Start with whatever you have.

A napkin sketch, a few sentences, a photo, a floor plan, a design brief or an existing model. Mix them in one conversation and the agent turns them into a 3D design you can build on.

A sketch

Snap a photo of the back of an envelope. Rough is fine.

A design brief

Add your design and area requirements. The agent turns them into an editable model.

Simple enough for anyone. Powerful enough for architects.

Most design software makes you choose between easy and capable. Arkio is both: the agent handles the hard part, and you stay free to shape everything.

Simple enough for anyone

No installs. No training. No modeling.

Opens in your browserOn the laptop, tablet or phone you already have. Nothing to install.

Talk to it like a personDescribe what you want, or sketch it. The agent does all the modeling.

Share with one linkClients and colleagues join in a click, always on the latest version.

Nothing to breakEvery change can be undone, so you can explore freely.

Powerful enough for architects

Real geometry. Real numbers. Real handoff.

Measurable 3D, not picturesAreas, heights and layouts you can rely on, in every view.

Built for big modelsBring in Revit or Navisworks context and keep working at full speed.

Review the model you already have, together.

Open your SketchUp, Revit, Rhino, Archicad or Navisworks model and review it together. The agent assists with design reviews too.

Ask the agent to find and highlight things, like every door or every room over 30 m²
Turn layers on and off, and add notes where they matter
Run checks on the model, like corridor widths or stair headroom
Optimize layouts and plans together with the agent, using movable objects from our Revit, Rhino, SketchUp and Archicad plugins

From the first idea to a decision everyone has walked through.

Most tools cover one step: the idea, the conversation or the walkthrough. Arkio does all three on one live 3D model, so nothing gets lost along the way.

01Sketch it

Explore ideas without modeling a thing.

Describe what you want and watch the agent build it in 3D, live. Ask for alternatives, compare them side by side and keep the one that works. Hands-on when you want, hands-off when you don't.

Options on demand, not just one answer
Follow the agent as it models, from any angle

Show the finished look from the very first meeting.

Every image and film comes from your real 3D model, so it shows the design you actually have, at its actual size. Most AI render tools start from a flat picture and fill in the gaps.

Make the big decisions while changes are still cheap.

Arkio is where ideas take shape and the big decisions get made, early in a project. When you're ready for detail, hand a clean 3D model to the tools your team already uses.
