BIM on every project. Coordinated against the output specification before anything is built.
Service family housing for the defence estate — permanent homes manufactured in Newhaven, East Sussex, by an accredited volumetric manufacturer with capacity to commit.
SEMCO has not yet delivered a scheme on the defence estate. This page sets out the capability we have built and what we intend to do with it. We would rather say that plainly than imply a track record we don’t have.

Permanent family homes built to the same standard as our council and housing association work — EPC A, BOPAS-accredited, warm and cheap to run.

Our factory, our process and our accreditations are the ones used on our housing and education work. The building type changes; the manufacturing does not.
Newhaven, East Sussex. Capacity engineered to 350 modules a year.
3D primary structural systems. Modules leave with structure, envelope, finishes and services installed.
BOPAS. ISO 9001. ISO 14001. Cyber Essentials. Constructionline Gold with the Common Assessment Standard.
Most estate work reaches manufacturers through primes and frameworks. We are building those relationships now.

BIM on every project. Coordinated against the output specification before anything is built.

Factory-controlled production in Newhaven. Repeatable tolerances. Quality assured at source.

Modules arrive substantially complete. Minimal time and minimal trades on site.
We can supply modules to a prime, or deliver a complete building with groundworks and scheme management. Either way, one accountable manufacturer.

We are working towards the accreditations and framework positions the estate expects of its supply chain, and we are in conversation with primes who need volumetric capacity in the South East. When we have delivered a scheme, it will be on this page with the numbers. Until then, what we can offer is a factory you can walk round, an accredited process, and capacity we can commit to.

We are open to conversations with primes, frameworks and estate teams. Come and see the factory — visits take an hour.
