unitize enables designers to automatically generate residential layouts for building masses inside Revit.

The problem

Most residential projects follow a similar design workflow, where the designer completes a site assessment that considers a number of building or council requirements. This is often a long and repetitive process.

The designer has to create layout after layout, iterating until they find a unit mix and floor layout that’s not only desirable but also meets all the necessary requirements.

The solution

unitize is a Revit plug-in that speeds up the process of assessing residential building layouts. It eliminates this cyclical process by accelerating the assessment and reassessment of the designer’s masses.  

It works by creating unit or flat mixes for a Revit mass from a set of parameters predefined by the user. Units can be stacked or randomised to create multiple layout options that designers can print off, assess and sketch over.  

What makes unitize different?


unitize integrates with Revit for a seamless design workflow so there’s no time wasted switching between design programmes.

Fully-customisable variables

The width and depth of units is customizable to match your project requirements allowing for extra flexibility.

Instant design feedback

Users can make quick adjustments to residential masses and receive instant feedback on changes to unit count and density.

Ready for layouts

unitize's generic model families can be easily replaced with custom elements showing your typical layouts for quick plan studies.

Faster unit mixing

Unit mixing
unitize places units inside a mass from Revit, optimising for best fit and space efficiency (and taking into account required cores and units). Users can add a different unit mix to a Revit mass element at any time through the ‘Unit Percentage Mix’ section. Any adjustment in these fields will prompt unitize to recalculate the results in the ‘Analysis’ section.

Custom flat sizes
unitize comes with pre-set flat types that are based on the four most common available: studio, 1-bedroom, 2-bedroom and 3-bedroom. These are managed using generic models pre-loaded with colours and parameters for each type. Width and depth dimensions (mm) for each flat type can be adjusted via the ‘Settings’ menu.

Live data
unitize automatically generates accurate assessment metrics on mass layouts, including: Total Area (m2), Height (mm), Mass Efficiency (%), Number of Floors, Number of Cores and Number of Units. unitize also provides comparative data for Unit Mix (input) vs Unit Mix (output). Any changes made to inputs in Revit will instantly update on the unitize dashboard.

Fully-integrated with Revit

Easy adjustments
unitize is linked to mass elements in Revit so it recognises any geometric changes made to a mass by the user. Any modifications on a mass in Revit will automatically be reflected in unitize. This also means the user can move a mass to a different position on the site layout and unitize will remember the mix and replace units.

Replaceable Revit families
unitize supports users throughout the design process, from early-stage feasibility studies to concept refinement. Once the user has chosen a layout, they can easily swap automated generic model blocks for their own content, such as unit type groups and 2D plan families.

Independent processing
unitize processes calculations from user inputs outside of Revit to ensure a quicker, more seamless processing experience and faster outputs.

What unitize users say

Kent Burns
MAKE Architects

"This plug-in allows us to carry out more iterations - we can assess things faster. It's the turnaround in decision-making that has been improved.

We don't see it as a design tool; it's all about analysis, breaking down areas to see what we could feasibly be achieved."

Gavin Crump

"I found this to have a really good user interface, it made sense to me really quickly. One great thing the tool allows us to do is revisit our designs once things change.

My verdict is: the tool is awesome! It’s really impressive, especially for a Revit based add-in."
