The Architectural Concepting App

The first purpose-built tool for the concept design stage of the architectural process.
We are the missing step between pen and paper and cumbersome, slow BIM programs.
We combine the ease of sketching, the power of BIM data, and specialist project visualisation tools to allow you to get robust data and feedback at the speed of sketching.

Explore all the angles

We give you the tools to know what is feasible and explore what could be possible, to capture the most value and potential from every project. In minutes you can have a building in a 3D model with volume, material considerations, street presence, context and sun studies and code compliance. And then, you can endlessly iterate and explore to push your idea further; concepting is the art of the possible.

Combining sketching with computational design and space planning, Codesign provides a fast, fluid, and flexible approach to iterate building concepts, test options, and refine your designs.

With accurate building data at your fingertips, make informed design decisions every step of the way. Charts update immediately with every change giving you real-time data as you create, edit, and iterate your design.

Still buggy

Changes are not reflected on 3D model, chat support doesn’t work, and sun study turns the whole app dark and you can’t undo it.

Developer Response ,

The Sun Study is dark because it starts at sunrise, it then 'lightens up' as the day progresses (use the play button to activate). All changes are reflected in 3D so there must be an issue with your building. We do respond to all chat messages during business hours or you can email us direct on - you can show screen shots and/or screen recordings to show any issues you are experiencing. We look forward to hearing from you and solving your issues.

To Expensive…

The cool thing about an app like this is it allows hobby concept designers to dream before sending plans to certified Engineers and Architects…

So I honestly do not see the value in this App beyond a 1 time or low annual subscription fee.

I don’t know what world these guys live in, but I’m getting the impression that it’s a delusional entitled bubble with little understanding of real estate, and practical use of such a tool.

So paying the insane subscription or searching google for hundreds of professional concept examples for free, I say go free…

Hope to see changes…

3D Problem

Since the last update When I open the application sometimes some 3d models do not show up and sometimes none do show up, only the 2d
