Housing developer · Covering the South of England
SEG Construction secures consented sites, funds and builds them at our own risk, and delivers finished homes, including 100% affordable schemes handed over to Registered Providers and councils through Homes England.
SEG is a hybrid development and construction company. Around 90% of our work is our own development schemes, and we still act as principal contractor for others. From the land up, we manage planning, funding, construction and handover as one CIOB Chartered Building Company.
Now completing · Impington, Cambridgeshire
38 apartments on the Cambridgeshire Guided Busway, with direct public transport into Cambridge. SEG developed the site and built it, from groundworks and the podium slab through to the steel frame, envelope and fit-out.
The building steps up to four storeys at the corner, with brick, white render and dark standing-seam gables, and has landscaped communal gardens to the north and south.
On site & starting
Contemporary homes on a wooded hillside site above Watcombe, with timber cladding, render and green roofs. It is an SEG development, started on site in July 2026 on a 12-month build programme.
Four new houses and five apartments off Malta Road in Cambridge, in buff brick with standing-seam details around a landscaped shared drive. The scheme has full planning consent, and SEG is the developer and builder.
The Homes England route
We work directly with Homes England under the Social and Affordable Homes Programme 2026–2036 to bring forward fully consented, 100% affordable schemes. We carry the development and construction risk; our partners take a finished, warranted scheme at a fixed price.
We acquire land with planning in place, or take it through planning ourselves, so there is no outstanding planning risk before grant is sought.
We go to Homes England directly to confirm the grant route and indicative support for the scheme.
A Registered Provider or local authority agrees Heads of Terms and a fixed turnkey price, backed by an independent RICS valuation, and the formal bid goes in.
SEG funds and builds through to practical completion. Cost-overrun and construction risk stay with us, not with the partner.
Phased or single handover with a 10-year NHBC (or equivalent) warranty, full Building Regulations sign-off and an agreed defects period.
Registered Providers or local authorities interested in taking a scheme: get in touch.
For Registered Providers & Homes England
We make new affordable homes simple to take on: consented sites, a fixed price, and one accountable developer and contractor from land to keys.
We fund and build to practical completion. Cost overruns, programme and construction risk sit with SEG, not with the grant recipient or the landlord.
A turnkey price is set before start on site and backed by an independent RICS valuation. There are no variations to manage and no surprises at handover.
We bring schemes forward with planning already in place, so grant can be committed with confidence and homes start on site quickly.
As a CIOB Chartered Building Company, we run design, procurement and construction ourselves. That gives you one point of contact and one line of accountability.
We shape the tenure mix, unit sizes and nominations around your affordable housing policy, weighting towards social and affordable rent where you need it.
SEG is a Tier One approved contractor with Together, Paragon, Assetz Capital, Triple Point and Proseed Capital, so schemes are properly funded from day one.
What you receive at handover
Affordable housing experience
We have consented, grant-ready schemes in the South West now, with more coming through our Cambridgeshire and South East divisions.
For landowners
Selling land to a developer means someone else takes the development profit. In a joint venture with SEG, you keep a share of it. Our figures show an uplift of 50–80% on the value of your land.
The land is valued by a RICS-approved surveyor, and SEG designs, funds and builds the scheme. As units sell, you're paid the land value plus your share of the profit. The process is transparent and run by a CIOB Chartered Building Company with an ISO quality management system.
Your protections in a joint venture with SEG
As a CIOB Chartered Building Company, we run design, procurement and construction ourselves. That gives you one point of contact and one line of accountability.
SEG guarantees the agreed land value, set by an independent RICS valuation. You know your minimum return before work begins.
We design and build the scheme for a fixed lump sum, so construction costs are agreed up front and overruns are ours, not yours.
The build is carried out to a fixed term agreed at the outset, so you know when homes will complete and when you'll be paid.
Contingency is built into every appraisal, so that if SEG were unable to finish, another construction company could be appointed to complete the build.
Introducer fee · all routes
The fee applies across everything we do: sites for our own developments, affordable schemes on the Homes England route, landowner joint ventures and build contracts. When we take forward a site or project you bring us, you receive 1% of the land value plus 1% of the build contract. Terms are agreed with you before any introduction.
