Adaptable living modules
Eight modules of equal footprint mean a bedroom today can become a study, a workshop or a rented room later, without touching structure.
Affordable modular housing
9 modules. One smarter home.
9 Cubits homes are built from 9 coordinated modules around a central utility core, cutting cost, energy use and build time without cutting quality of life.

The system
Four decisions that make a modular home affordable to build and to live in
Central utility core
Plumbing, ventilation, electrical distribution and the hot water plant sit in one factory finished cube at the centre of the plan.
Low energy by design
A compact three by three footprint has less external wall per square metre, so a well sealed envelope does more with less.
Faster, lower cost build
Repeating one module dimension 9 times keeps drawings, trades and materials predictable from the first home to the fiftieth.

How it works
From a 9 square grid to a finished home
1. Set the grid
Start from the fixed three by three plan. Choose which of the eight outer modules are living, sleeping, service or outdoor space.
2. Build the core
The utility core is assembled and tested off site, arriving as one unit with services terminated and ready to connect.
3. Assemble on site
Modules land around the core on a prepared slab or screw pile foundation, so wet trades and site time both shrink.
4. Adapt over time
Because every module shares a dimension, a household can reconfigure rooms or add a second storey grid later.
Energy efficiency
Shorter runs, tighter envelope, less waste
Putting every service in the middle of the plan means no module is more than one step from hot water, ventilation or power.

Shorter plumbing runs
Kitchen and bathroom modules sit against the core, so hot water arrives quickly and less heat is lost in the pipe.
Simpler electrical distribution
One distribution point in the middle of the plan means shorter cable routes and fewer penetrations through the envelope.
Better thermal performance
A compact square plan has less external wall for the same floor area, and the warm core sits inside the insulated envelope rather than on an outside wall.
Balanced ventilation
Supply and extract runs radiate the same short distance to every module, which makes commissioning a repeatable exercise.
Who it serves
Example scenarios, shown to illustrate how the system could be applied.
Individuals and first home buyers
A two bedroom starter grid that can grow into three or four bedrooms as a household changes, without a full renovation.
Community housing providers
Repeatable layouts and one service core simplify maintenance across a portfolio, because every home has the same plant room.
Developers and municipalities
Predictable module counts make feasibility, consenting and staged delivery easier to model across an infill site.
About the name
9 squares, and an old unit of length
9 Cubits takes its name from a low energy house design based on 9 squares in a three by three grid, with eight living modules arranged around a central utility core.
A cubit is also an ancient unit of length, measured from the elbow to the tip of the middle finger. It is a reminder that useful dimensions have always been drawn from the human body, and that a plan works when its measurements suit the people inside it.
Put together, the name says exactly what the system is: a set number of modules, measured on a human scale.
