Architecture & Design

Ever opened a professional CAD package, spent an hour fighting the interface,

and given up before you drew a single wall? This is the opposite of that.

Architecture & Design gives you the tools real architects work with — a true

parametric model where every wall, roof and stair knows about the others —

wrapped in something you can pick up in five minutes. No timers. No

resources. No enemies. Just a plot of land, a full toolbox, and as much time

as you feel like taking.

Parametric from the very first line

Draw your plan the way an architect does, and watch it think along with you.

Dimension chains update live as you drag a wall. Corners mitre themselves.

Rooms are recognised the instant you close them. Your 3D house rises at the

same moment — the plan and the building are the same thing, always in sync.

Change your mind at any point. Move a wall and every measurement, every

corner, every room area follows. Raise a wall and the roof above rises with

it. Nothing to rebuild, nothing to patch up.

Build anything you can picture

Cut in doors and windows and place them to the centimetre. Crown it with a

gable, hip, shed or flat roof, or open it up as a terrace — then set the

pitch, the overhang on each side individually, and turn the whole thing

through any of four directions. Add roof windows. Stack storeys. Open a

stairwell through the ceiling.

Stairs are parametric too: straight or winding, solid or open riser, with the

step count worked out from the height you give them and railings that follow

every turn of the run.

Make it unmistakably yours

Furnish from a deep catalogue — kitchens, bathrooms, sofas, beds, lighting,

storage, plants, pictures, decoration — or bring in your own models as OBJ or

GLB and place them like everything else.

Then paint. Every surface takes any material, inside and outside separately.

See a finish you like across the room? Lift it with the eyedropper and carry

it anywhere. Tune colour, brightness and tiling until it reads exactly the way

you imagined it.

Three places to build

A green plot on a quiet street, a beach at the edge of the sea, or a clean

white plane with nothing on it but your idea. Move the sun and watch your

rooms change completely from morning light to golden hour.

Then live in it

Step inside and walk your own rooms at eye level. Stand in the doorway you

drew an hour ago. When the light falls just right, open photo mode and keep

the shot.
