Shell Build
We take the hard part.
Homebuilding is fragmented, and 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. Shell Build puts it back together.

Many clients take the shell and bring in their own trades. For A rated EPC projects we can take it through to fit-out and decoration, heat pump, solar and battery, MVHR and smart controls — to completion.

Project
What our clients say
“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.”
Living in your home
A home that feels good to live in.
Warm in winter, cool in summer
Airtight and well insulated, with overheating designed out. Comfortable in every room, all year.
Low bills for life
Built to EPC A standards, where typical energy bills are around 20% of an average home's.
Move in sooner
Foundations and structure in weeks, not months, so you're living in your new home sooner.
Your home, your design
Your layout, your finishes, your specification. Built around how you want to live.
Mortgage and warranty ready. Built to be accepted by mainstream lenders and structural warranty providers.
Why it's simpler with us
Buying the kit doesn't guarantee the benefits.
Building with SIPs and timber frame is very different to traditional construction with bricks and blocks. The speed, comfort and low bills come from how the whole home is put together, not from the panels alone.
