McVeigh Offsite manufactures bespoke SIP packages for extensions, workshops, garages, garden buildings and specialist residential projects. Based in Greater Manchester, we work with homeowners, builders and contractors to deliver precision-manufactured panels ready for installation.


Achieve significantly better thermal performance compared to many traditional construction methods.

The high insulation performance of SIPs can often achieve better U-values with slimmer wall constructions.

Shorter build programmes can minimise disruption during construction.
We can manufacture bespoke SIP panel packages directly from your plans and provide technical guidance to help simplify installation.
Whether you're a homeowner, self-builder or contractor, our team can help identify the most suitable solution for your project.
