Six decades at the
heart of London
O'Shea Group was founded in 1966 as a concrete frame contractor. Over the following six decades, we evolved into something rarer in the industry: a family-owned group that is simultaneously a main contractor, a residential developer, and an equity investor.
Private ownership means fast decisions. A single decision-maker with the experience to back them. No committee approvals, no quarterly earnings pressure — just a considered view and a handshake commitment that holds.
We have been involved in over £2bn of UK development and delivered more than 17,000 homes. Our balance sheet — £172m in net assets, £57m in cash — allows us to take genuine equity stakes in the projects we build, aligning our interests completely with our partners.
Where we work
How we deliver
Joint Ventures
We enter JVs as genuine equity partners — bringing capital as well as development and construction expertise. We have a long track record working with major developers and funders.
BSA & PCSA
We are well positioned to prepare projects for BSR approval through Pre-Construction Services Agreements. Early engagement de-risks design and programme before the main contract award.
Design & Build
We have full D&B capability — managing the design team and contractor functions under a single point of responsibility.
RC Frames in-house
Our in-house concrete frame capability dates to our founding. From single-storey basements to 55-storey towers, we pour our own concrete.
MMC
We employ Modern Methods of Construction across multiple packages for gains in programme, quality and environmental impact.
Digital Construction
We are a leader in the adoption of digital construction tools to centralise design and coordination, and quality and progress on site.
What we stand for
Quality
ISO 9001 certified Quality Management System. We believe a quality product is its own best form of advertising — that's why 90–100% of our work comes from referrals.
Safety
Our ENGAGE Health, Safety & Wellbeing programme puts people first. Zero-harm ambition backed by site management systems and a culture of personal responsibility.
Sustainability
BREEAM Very Good and Excellent ratings across our portfolio. We design and build for whole-life performance, not just planning compliance.
Cost Certainty
We own a financial stake in most of what we build — which means we think about cost the way a developer does, not just a contractor. No hidden costs. Real value.
Programme
Own site staff, concrete operations, and finishing trades under a single management structure means we control the critical path — not sub it out.
Satisfaction
We are only as good as our last job. That is not a cliché — it is the operating principle behind every decision on every site.
