Talos3D Architecture · AI design partner for buildings

Design your building in conversation.

Describe what you have in mind with a sketch or a few sentences. Talos3D Architecture's design agent turns it into a real building model that you can explore, change and draw from. It knows a door from a wall and checks its own work. It also tells you plainly what is settled and what still needs a professional. Edit directly, ask an AI agent to continue, or weave both into the same task. You work on one shared model, with every operation traceable.

Watch a cottage take shape.

An idea becomes a 5 × 6 metre cottage in four prompts. Follow the model and its AI conversation, then look beneath the finishes at the timber frame.

A five-by-six-metre cottage. Two rooms. A small bathroom. And a roof that opens up the space inside. Let’s build it — in conversation.

First, the brief. Set the footprint, the roof, the character. Talos3D Architecture gives that idea a shape we can explore. Turn it around. Check the proportions. There’s our starting point.

Now make room for living. Two rooms, a compact bathroom, places to sleep, and doors opening towards the lake. Windows and shutters become shared components. We can inspect the layout, check the clearances, and refine the same design.

And then — the construction. Ask for timber framing, and look underneath the finishes. Individual studs. Plates and headers around the openings. Above them, timber rafters meet a glulam ridge beam. The wood has material properties too: density, stiffness and strength grade. Follow the supports down through the gables to the foundation. These are editable parts of one coordinated model. This is where the design starts to explain how it goes together.

Keep asking useful questions. Does everything meet? Can the doors and shutters move? How does the foundation change? Inspect the junctions, compare the options, and take drawings and quantities from the model. The remaining engineering decisions stay visible, ready for the next conversation.

From a sketch to a cottage you can explore, refine and understand. Your design judgement. An agent helping you develop it. One editable model. Talos3D Architecture.

Read the four prompts
  1. The idea

    Start an empty Talos3D Architecture project from my sketch: a Swedish lakeside cottage with a 5 m east–west by 6 m north–south wall footprint, north/south gables, a 22° roof, 300 mm overhangs and 2.30 m clear eaves height. Keep the rooms vaulted. Use NCS S 0502-Y horizontal siding and timber shutters, NCS S 1002-B vertical gable boards and trim, and charcoal standing-seam roofing. Begin with simple editable massing and four elevation views. Keep assumptions visible and save a first version. Work in perspective while developing the model.

  2. Make room for living

    Follow the sketch layout: put the 1.25 × 2.73 m clear bathroom in the northeast corner, with access from the north room through its west side and from the south room through its south end. Include a 900 × 900 mm folding shower, WC and basin. Place a 1600 × 2000 mm double bed against the north wall, and another against the east wall in the south room. Put a round dining table and four chairs in the southwest. Divide the rooms west of the bathroom with four 625 × 1940 mm folding leaves in a 2.52 m opening. Use a centred south glazed double door with a 1500 × 2020 mm rough opening, plus a 1300 × 2020 mm double door in each west room, with sliding shutters. Place shared M12×6 high windows in both east rooms and the north gable: 1180 × 580 mm frames, heads 2010 mm above the floor. Reuse product types, check clearances and save the layout.

  3. Reveal how it goes together

    Keep the layout and develop the timber construction: 45 × 145 mm wall framing with plates, corners, headers and jack studs; insulation, wind protection, ventilated cladding and an internal service zone. For the vaulted 22° roof, use notched 45 × 220 mm rafters, 220 + 45 mm insulation and layered standing-seam covering. Support a 140 × 405 mm glulam ridge through both gables, using 140 × 140 mm posts and 145 × 195 mm transfer headers above their openings. Assign C24 to solid timber, GL30c to ridge and transfer beams, and GL30h to the posts, with timber appearance, density and stiffness. Compare slab and pier/bearer/joist foundations, then select the slab for this cottage. Show the frame separately from the finishes, check support contacts and save both studies. Keep capacity, connection and site decisions open for engineering verification.

  4. Inspect and deliver

    Use the selected slab foundation for the final model. Inspect the design: clashes, unsupported parts, door and shutter clearances, continuous supports, and roof and wall junctions. Resolve modelling issues and retain open engineering decisions. Check geometry and timber properties after saving and reopening. Produce a dimensioned north-up plan, four elevations, wall/roof section, foundation comparison and quantities from the model. Save the native projects, reusable components and verification report. Finish with the cottage and a clear handover of what is resolved and what remains.

Who it's for

A design partner for every stage before the build.

Homeowners & self-builders

Explore your own ideas first.

Try layouts, rooms and rooflines before you meet an architect. Arrive with a model and drawings that show what you want, plus a clear list of questions for the professionals.

Architects

Explore more options, faster.

Test variants with the client in the room. Plans, elevations and sections keep up with every change, so your time goes into design, not redrawing.

Builders

Start from something buildable.

Framing, real door and window sizes and foundation alternatives sit in one model. The open engineering questions are listed up front, not discovered on site.

What makes Talos3D Architecture different

It understands what it is designing.

Most AI tools make pictures. Talos3D Architecture builds a real model of the building, where every wall, roof, door, window and stud knows what it is. That changes what an AI partner can do for you. Each point below was put to work in the Reference Cottage project.

How it works

You and your AI agents, working on the same design.

Move a wall yourself, ask an agent to develop the framing, then refine a window together. Switch freely between direct editing and conversation, alternating or interleaving tasks as the design develops. Each picks up from the current model.

Every operation stays in a shared history, whether it comes from a person or an AI agent. Trace who changed what, review the sequence and revisit decisions. The model keeps its context, and you keep control of the design.

  1. DescribeShare a sketch, a photo of the site or a few sentences about what you want.
  2. Work togetherEdit with the modelling tools or ask an agent for changes. Alternate and interleave both within the same task.
  3. ReviewFollow every human and agent operation in the shared history. Check the result and keep unresolved questions visible.
  4. Take it furtherBring the model and drawings to your architect, engineer or builder.

A real project · Reference Cottage 5×6

From napkin sketch to blueprint set in two evenings.

A hand sketch of a 30 m² lakeside guest cottage went to the Talos3D Architecture agent. After two evenings of conversation there was a framed, insulated model built from real products. It came with eight A3 drawing sheets and pictures of the cottage on its site and inside.
