We are more than an offsite manufacturer.

With over 50 years’ experience in offsite manufacturing, we bring expert design, manufacturing and project delivery skills together to create high-quality pharmaceutical facilities. Our flexible modular solutions can be used to meet requirements for permanent and temporary facilities.

We’re building relationships, trust, and a future where buildings are smarter, delivered faster, and are more sustainable. Our unwavering commitment to quality, safety, and customer satisfaction sets us apart. When you choose McAvoy, you’re choosing excellence.

“We are delighted with this new facility which will attract and retain high value businesses and jobs, complementing Porton Science Park’s vital role in supporting the unique science and technology expertise at Porton Down.”
Cllr Richard Clewer
Leader of Wiltshire Council

What we do

Our use of offsite manufacturing can reduce programmes by up to 50 percent, delivering a faster return on investment and a reduced risk profile on commercial development. Our facilities meet the need for production agility and capacity flexing, with adaptable solutions that can be expanded, repurposed and redeployed depending on demand.

We deliver pre-designed, tested and validated solutions for both purchase and rental, providing ultimate flexibility and surety of quality. Our buildings utilise the same materials as traditional buildings but we use them in a smarter way. For example, we can pour concrete floors in the factory further reducing time spent on site.

Permanent Solutions

We specialise in turnkey design and build solutions for the pharmaceutical sector, managing projects from conception, through design to completion. Our volumetric modular solutions represent a time-efficient, quality controlled and environmentally sound method of construction.

Early engagement and consistent collaboration with our clients enables faster and better decision making, and our consultative style includes an open BIM approach to achieve consistently high levels of client satisfaction.

Each module is manufactured in our state-of-the-art manufacturing facility and is up to 70% complete before being transported to site, resulting in minimised disruption to live operations and reduced time spent on site.

Temporary Solutions

With a brand-new fleet of sustainable modular buildings, McAvoy can respond quickly and deliver temporary accommodation to you when you need it most. We offer a range of high-quality, adaptable modular solutions for rental & sale. If you have an urgent requirement, a semi-permanent solution can prove to be the most efficient solution.
