What is a modular home?

Are you thinking about how to build your new home, but finding it hard to decide which construction method to choose? We understand it's a big decision, and we're here to help make it easier for you.

Chances are, you're considering alternatives to traditional construction methods due to their complexities and challenges. Well, modular homes might just be the answer you're looking for, offering a range of benefits that could suit your needs perfectly.

In this blog, we'll walk you through how modular homes are built and provide you with the knowledge and confidence to navigate this construction approach with ease and certainty.

What is a modular home?

Built primarily in a manufacturing facility, modular homes are built in sections to around 90-95% completion off-site. These modules are then transported and assembled on the building site. Once installed on the foundations and connected to the services, modular homes are permanent dwellings just like traditional built homes.

The modular building process

After the design and paperwork are complete, the modular building process begins. This is usually divided into the following key stages:

1. The frame stage

The first step of modular construction is to build the house frame. Most modular companies use steel for the base frame as it is strong, reliable, and able to withstand transport on a truck. During the framing stage, the carpenters will install the particle board flooring, build the timber wall and roof structure, and brace the frame. When this work is complete, a Building Surveyor will inspect the frame.

A key benefit to building homes in a factory environment is that it significantly reduces waste and the environmental impact on site. This is facilitated by the ability to store excess materials for future use, rather than disposing of them. Furthermore, the trades constructing the homes primarily work within the factory environment until the home is transported to the site, minimising disturbances and the environmental impact on-site.

2. The lock-up stage

The next step is to add all the exterior features onto the prefabricated frame so that it is a weather tight and secure home. This includes the roofing, guttering, external cladding, windows, doors, and decking. During this stage, the electrical and plumbing contractors will also run their wiring.

Since this stage takes place in a controlled environment, the contractors can work quickly and without delay. It also allows for smoother workflows and more refined collaboration between different subcontractors.  

3. The fixing stage

During the fixing stage, all the surfaces and fixtures are added, such as carpentry, cabinet making, plastering, tiling, plumbing, and electrical. The last step of the fixing stage is to install the flooring, at which point, the home is ready for delivery.

4. Site preparation


Before the modular home is scheduled for delivery, all the site preparation needs to be completed, including excavation, foundations, and retaining walls. This way, your site will be ready for installation on delivery day. One of the key benefits of modular construction is that you can complete this step at the same time as the factory construction phase, resulting in faster timelines so you can move into your new home sooner. 

5. Delivery and installation

When the house and building site are ready, the house will be loaded onto a truck and delivered to its location. Once it arrives, the modules are reassembled and made into one cohesive unit. At Anchor Homes, this process takes as little as one to three days, depending on your location and the size of your project.

The remaining site work can then be completed, including any of the following finishing touches: 

  • Plastering.
  • Painting.
  • Sub-floor cladding.
  • Commission of the electrical and plumbing infrastructure.
  • Stairs and balustrade.
  • Connection to site services.
  • Construction of the garage or carport (if included).

At this point, the Building Surveyor will complete a final inspection before issuing a Certificate of Occupancy.
