What Telereal Trillium does

Telereal Trillium (trading as TT Group) is one of the UK's largest privately owned property investment and development firms, established in 1999 and headquartered at 5 Aldermanbury Square, London. The company operates a £8bn+ portfolio comprising over 7,500 properties spanning 65 million sq ft, alongside a residential development pipeline of more than 22,000 homes. TT Group reports 251–500 employees and structures its business around five integrated service lines: Private Capital (deploying £2bn of investment equity into large corporate deals), Property Investment (acquiring commercial assets with in-house asset management), Strategic Land (via wholly-owned subsidiary Lands Improvement, targeting 200–5,000 dwelling greenfield and brownfield sites), Development (residential-led brownfield schemes with a planning permission track record), and Portfolio Partnership (working with large occupiers to optimize complex portfolios through cost reduction, capital release, and business transformation).

The business generates revenue through a mix of capital appreciation and rental returns on its property investment portfolio, development profits on residential-led schemes, strategic land sales through Lands Improvement, and fees from portfolio partnership engagements. Pricing is quote-based and negotiated at the enterprise level, reflecting the bespoke nature of large corporate real estate transactions. Go-to-market is direct enterprise field sales targeting large corporate occupiers and institutional investors, with deal sizes ranging from single assets to portfolios and large-scale corporate transactions. The model is B2B and high-ticket, with relationships and execution credibility serving as primary origination channels. A December 2025 transaction — the £50m GDV sale of a Croydon industrial development site to Kennedy Wilson — illustrates active asset rotation as part of the broader asset management strategy.

TT Group's competitive position rests on 25 years of operating history, scale advantages from the £8bn portfolio, and £2bn of deployable equity, which together create barriers to entry in large UK corporate property transactions. The company is privately held and does not disclose revenue figures; firmographic data, segment composition, and customer logos are not publicly available beyond target segment descriptions. Geographic focus is exclusively UK-domiciled, and there is no public indication of international expansion or technology-led differentiation.
