Cities
Shape streets, blocks and skylines. Start from a real area or develop a new setting with its own density and architectural character.
Generate editable 3D cities,
buildings and interiors.
Start with a real place, a reference or an idea. Create a connected world, from the streets to the rooms inside.
Start with the city.
Explore the streets and buildings, then move closer to the spaces inside.
Continue inside.
Review floors, rooms and the routes that connect them.
Give each space a purpose.
Work with furniture, materials and the objects that make a place usable.
WHAT YOU CAN CREATE
From the city block
to the room inside.
Work across cities, buildings and interiors in one editable world. Set the character of a neighborhood, develop a building or work through the details of a single room.
Buildings
Develop facades, materials, roofs and entrances. Explore different directions while keeping the building connected to its surroundings.
Interiors
Lay out floors, rooms and circulation. Bring in furniture and materials, with spaces and objects that retain their identity.
BUILT TO BE INHABITED
A chair is more than
a shape in a room.
A chair belongs to a room. A door connects two spaces. Perplace keeps these relationships alongside the geometry, so your design tools, game or simulation can use them.

living/armchair-2
Read from the world model. Every field is a fact an agent can query or a change you can ask for.
“Go to the armchair in the living room.” The place, the object and its use are part of the world. NPCs and agents can use that information to navigate, sit, open doors and interact.
YOUR WORKFLOW
Describe. Explore. Refine.
Direct the result from the overall setting to the details that matter to your project.
Start with a place
Choose an area, bring references or describe something new. Set the scale and what the place is for.
Set the direction
Define the architectural character, building types and spaces your project needs.
Review the world
Explore the result in 3D. Move from the streets to the building and the rooms inside.
Change the details
Refine a facade, adjust a layout or rethink a material. Work on the selected part of the design.
Keep the connections
Buildings, floors, rooms and objects stay part of the same structured world.
Use it in your project
Bring the visual scene and its spatial data into your design, game or simulation workflow.
Keep the place.
Change the design.
Explore a different facade, material or architectural character on the same building. Compare directions in context as your design evolves.
Only the selected element changes. Everything around it stays exactly as it is: the other buildings, the streets, the objects and the materials you did not touch.

Different projects.
The same depth.
Architecture & urban design
Explore urban contexts, building forms and spatial layouts. Compare design directions from the block to the floor plan.
Interior design
Develop rooms, circulation, materials and furnishings together. Review a space in the context of the building around it.
Games & NPC housing
Build homes, workplaces and streets for NPCs to inhabit. Connected rooms and interactive objects give their routines a place to happen.
Simulation & research
Build spatial scenarios with identifiable places, connected rooms and usable objects. Give agents a world they can navigate and interpret.
TAKE IT WITH YOU
More than a mesh.
Your project receives the visual world and the relationships within it. Buildings, rooms, doors and objects retain their identity beyond the image.
Choose the format your workflow needs.
Use glTF / GLB or USD for the 3D scene, JSON for structured world data, and simulation grids for spatial environments. Materials and interactions can be mapped to your own tools.

HOW IT IS BUILT
You direct the design.
Perplace builds the world.
Perplace combines AI design, procedural construction and visual review. Your brief guides the result; geometry and spatial checks help keep the pieces connected.
01
Design
References and instructions guide the architectural direction.
02
Build
Procedural tools construct the geometry and spatial relationships.
03
Review
Visual evaluation compares the result with the brief and guides refinement.
Refine the parts that need attention while keeping the wider design in view.
PRIVATE BETA
Small batches.
Real projects.
Bring a real project to the private beta. Each pilot starts with a defined place, a use case and the output your workflow needs. Pilots are paid and priced per project, with founder terms that stay with you.
What you get
A world built from your area, reference or brief. The data model, the exports and the viewer. A direct line to the team behind it.
How it works
Describe the place, its purpose and the tools you use. Projects are selected by fit, with scope and delivery agreed before the pilot begins.
What is expected
A real use case, honest feedback, and patience with rough edges. Projects that can be shown publicly are welcome, never required.
QUESTIONS
What people ask.
What can I create with Perplace?
Editable 3D cities, buildings and interiors. Start with an area, a reference or a written brief, then develop the streets, architecture and spaces inside. A pilot can focus on one building or interior as well as a larger setting.
Which engines and tools can read it?
Anything that opens glTF or USD: Blender, Unreal Engine, Unity, Godot, Houdini, Omniverse, three.js. The JSON model is plain data your own code reads directly. Materials are named, so you map them to your library.
Are the places real or invented?
Both. Start from a real area (streets, footprints and heights come from open data) or describe a place that does not exist. Interiors are always generated, so the rooms and objects are never a copy of a real home or office.
Can I bring my own area, references or style?
Yes. An address or a bounding box, reference images, a written brief. The AI architect reads them and the visual judge checks the result against them. You can then ask for local changes without regenerating the rest.
Is Perplace only for games?
Perplace is for creating places in 3D. Design teams can explore urban contexts, buildings and interiors; game teams can develop environments; simulation teams can work with connected spaces and structured data. The pilot is scoped around your project and workflow.
How do I start a project?
Describe what you want to create and add references if you have them. Perplace is in private beta, so the project form sends a request to the team. Scope, fit and delivery are reviewed before a pilot begins.
YOUR NEXT PROJECT
What place do you
want to create?
A city for a game. A building to explore. An interior to work through. Bring the place, the references and what you need to do with the result.
