100%
Turnkey responsibility - design, build, M&E and HVAC under one roof, one contract
We do our job, so you can get on with yours
Most fit-out projects involve too many moving parts for a business to manage alongside its day-to-day activities. Multiple contractors, compliance obligations, design decisions, cost management - it adds up fast.
SandBox removes all of that. We take on every element of your project - design, procurement, build, M&E, HVAC, compliance - and deliver a finished space that works for your business from the start.
Chris Mills brings over two decades of hands-on project delivery to every job, regardless of size or complexity.
