About Development Securities PLC
A leading UK real estate developer and investor

On 9 November 2015, property regeneration company U+I was launched following a merger between Development Securities PLC and Cathedral Group. The merger combines the complementary capabilities of the two businesses, specialising in best-in-class mixed-use regeneration to drive high quality consistent returns. See U+I for more information.
Development Securities PLC is a leading property developer and investor that creates maximum value for its shareholders through the management, financing and development of high-quality properties across the UK.
We apply deep experience in commercial real estate, ranging from complex mixed-use developments such as the iconic PaddingtonCentral, to the creation of an investment portfolio that has consistently outperformed the IPD index.
The present senior management team has followed a disciplined business model over the past 15 years, managing a diverse portfolio across a range of sectors and regions with a conservative use of debt, strategic joint venture funding and development partnerships. This prudent business strategy has enabled us to succeed even under the acute stresses in the property market in recent years.
Our major development projects have been forward funded by some of Europe's leading financial institutions, who value our expertise and track record of success.
