Architecture & Design Free Download

Have you ever opened a professional CAD program, spent an hour trying to understand the interface, and closed it again before drawing your first wall? Architecture & Design is the opposite. It gives you the power of a real architectural workflow with an intuitive interface that anyone can learn. Build with a true parametric system where walls, roofs, stairs, and rooms understand how they work together with direct visual Feedback in realistic real-time lighting. Just choose your plot of land, open your toolbox, and start designing at your own pace.

True parametric design from the start

Create floor plans the way architects do and watch your building adapt as you design. Move a wall and dimensions, room areas, and connected elements update automatically. Close a space and it instantly becomes a room. Your 3D building grows alongside your plan, and both always stay connected. Change your mind whenever you want. Adjust a wall, raise a ceiling, or modify the layout, and everything updates automatically. No rebuilding. No fixing broken parts. Just design.

Build anything you can imagine

Add doors and windows with precise placement. Create gable roofs, hip roofs, flat roofs, or open terraces. Adjust the roof pitch, overhangs, and orientation exactly the way you want. Add roof windows, create multiple floors, and design open stairwells through your ceilings. Stairs are fully parametric too. Create straight or turning staircases, choose different styles, and let the system calculate the steps based on the height you provide. Railings automatically follow the shape of your stairs.

Make every space your own

Furnish your creations with high-quality furniture (much more coming soon!), including kitchens, bathrooms, sofas, beds, lighting, storage, plants, artwork, and decorations. Want to use your own models? Import OBJ or GLB files and place them just like any other object. Customize every surface with your own materials. Apply different finishes inside and outside, adjust colours, brightness, and texture scale until everything matches your vision. Found a material you like? Use the "Alt" key to instantly take the Material you touch and apply it somewhere else, along with all material customizations.

Choose your building environment

Start your project on a peaceful green plot, a beach overlooking the ocean, or a space where only your imagination sets the limit. Control the sun and watch your design transform throughout the day, from soft morning light to warm golden hour.

Step inside your creation

Walk through your own buildings in first person (VR mode coming soon). Stand inside the rooms you designed, look through the windows you placed, and experience your architecture from the perspective of someone living there. When everything comes together, capture the perfect moment with photo mode.

Share your creations

Publish your finished buildings directly to the Steam Workshop. Explore designs from other players, subscribe to creations you like, and open them inside your own game. Walk through them, study the designs, get inspired by what others have created, and give them a rating if you want.
