Questions you might have
Q. How does we construct home extensions differently to traditional extensions

Q. Why use modular building for your domestic extension
A Less disruption, more quality consistency, better thermal performance, thinner walls, more design flexibility, less delays
Q. Why change from traditional building to modular home extensions
A. For over 10years we built traditional buildings, During a 3 year advanced construction program became involved in modular construction, where the benefits were clear to see.. Ever since we've developed & integrated these techniques to our individual residential projects.
