10 yearsBringing factory and site together
Homebuilding is fragmented. With SIPs and timber frame, even more so.
One firm supplies the kit, another lays the foundations, others fit the windows, roof and cladding. Every gap costs time and money.
We put it back together. Leading manufacturers, direct sourcing and one team as Principal Contractor, from foundations to handover.
Two ways to build with us
You choose the finish line.
We unlock value and reduce risk on both. You decide how far we take it.

“We’d almost given up on finding a builder for our SIPs home. The manufacturer introduced us to Dynamic Build, who delivered the frame and the on-site construction. Amazing results.”
“We researched timber frame before selecting Dynamic as our partner. Dynamic supplied and installed our frames in 10 days, then supported our team to achieve completed shells prior to significant flooding in the surrounding areas.”

Questions
Questions we get asked
SIPs or timber frame: which is right for my project?
We build with both, so we can help you choose. SIPs are insulated wall and roof panels: fast, airtight, thin walls. Timber frame is insulated timber walls with an engineered timber roof structure: flexible design, strong on price. The right answer comes from your site and your design. SIPs and timber frame are our specialism; where a project calls for it, and it brings clear benefits in delivery and in living in the home, we've also built with ICF and volumetric modular.
I've got quotes from manufacturers and have no idea what I'm getting, what I need, or what's missing.
That's what we solve. Quotes are scoped differently, so the lowest-looking one often isn't. Our Superstructure Options Review lines them up like for like: what each includes, what it leaves out, and what your project actually needs, across scope, thermal performance, fire, interfaces and programme.
Can you take on a complex build?
Built for the difficult ones. Tight sites, access complications, multiple party walls, challenging designs, high performance targets and fixed deadlines. This is where one team across design, manufacture and construction matters most.
How long does it take?
Foundations and SIPs structure in as little as 3 weeks, proven on a 200 m² home. Your programme is set out with your estimate, and confirmed before we start on site.
