EPC A, BOPAS-accredited houses and apartments for councils, housing associations and developers — manufactured in Newhaven, installed in days, and ready to let or sell from handover.
To help councils, housing associations and developers close the gap between housing need and supply — with homes that are built to last and delivered when we said they would be.
Detached, semi-detached and terraced houses built to the Nationally Described Space Standard and achieving EPC A. For councils building their own stock, housing associations delivering grant-funded schemes and developers building for sale or rent. BOPAS-accredited for warranty and mortgageability, delivered to a fixed programme you can commit a start-on-site date to.

Pre-engineered house types that shorten the route from site appraisal to priced proposal. Choose a type, confirm the site, and we give you a cost and a programme you can take to committee, board or funder.

Manufacture runs while groundworks are under way. Homes arrive substantially complete, so lettings and sales start sooner.
LCA certified. The evidence your net zero and Scope 3 reporting needs, not a projection.
Fabric-first design. Lower bills for residents, lower arrears risk for landlords, and running costs buyers can see.
Independent assurance of durability and design life, accepted by lenders and valuers. Supports mortgage lending for buyers and shared-ownership customers.
BIM on every project. Architecture, structure and services coordinated against your housing standards and the Building Regulations before anything is built.
Factory-controlled production in Newhaven. Repeatable tolerances. Quality assured at source, not on a wet site in winter.
Loaded on our own tower lifts, installed in days, commissioned and handed over ready to let.
We can deliver as main contractor — groundworks, enabling works and full scheme management — so you have one accountable partner from first drawing to handover.

The Building Safety Act 2022 places clear duties on clients, designers and contractors to plan, manage and monitor building work for compliance with the Building Regulations. Our integrated system is built for it. Design, manufacture and installation run through one BIM model, one ISO 9001-certified quality management system and a 14-gate project control process — so you can see who did what, when, and against which approved information.
One digital record from first drawing to handover: the coordinated design model, specifications, product data, inspection records and sign-offs. The golden thread is a legal requirement for higher-risk buildings. We apply the same discipline to every home we build.
Every stage of every project has a named owner — from client requirements, through design freeze and client sign-off, to manufacture, installation and handover. Responsibility is assigned in writing, never assumed.
Each module is inspected and recorded in production under our quality management system. The evidence is held against the module, the home and the project, and handed over with the building.
SEMCO is an approved supplier on the Everything Estates framework, operated by Place Group — so local authorities can appoint us by direct award or mini-competition without a full tender. Buy outright or lease over time: we structure finance around capital windows, grant timetables and budget cycles, so the right homes are never held back by the wrong funding model.
Developers and housing associations can appoint us to manufacture and deliver the homes, or as main contractor for the whole scheme.
