Secure Land

Having a property is usually the first step in building your dream home.

Without land, it is hard to choose a home model or determine what the balance of your budget for building is.

Step 2:

Modular Feasibility Study

This is where one of us comes out to meet you at the property and determine what size modules can be delivered.

There is a fee for this service but it’s a credit on the price of the home.

Step 3:

Choose Home Model

We now know what size modules can be delivered. You can choose a home model that meets your requirements. Start with the smallest one you will consider and work your way up to your dream home.
