About

Where it all started...

We’re a close-knit team that started out as a small family business and has grown over the years into one of the best known and well-respected modular builders in Western Australia. After all these years, one thing has remained the same – the importance we put on real connections, and honest, hard work.

Headed by Wayne McGrath, whose family history of building pre-fabricated housing solutions spans some 30 years, Modular WA is run by some of the most experienced professionals in the industry. In the early 1970’s, the McGrath Family pioneered the use of pre-stressed concrete floors and were one of the first in Western Australia to construct pre-fabricated housing using this new technology.

Since inception, the company has gone from strength to strength, winning multiple industry awards and gaining a reputation for delivering exceptional quality modular, transportable residential and commercial building solutions across the State.

Today, Modular WA is proud to be the leader in designing modern, affordable solutions, specifically for Western Australia’s unique landscapes and lifestyles. Our handpicked team of dedicated and knowledgeable experts believe in building genuinely better, innovative, modular homes, fit for the future.
