Walter Lilly – the story so far

When Walter Gent Lilly won the freehold to a London builder’s yard in a card game in 1924, he didn’t know he was making history. Capitalising on his good fortune, he embraced the building trade, became an immediate success and quickly grew his business to become one of London’s foremost construction companies.

Although it has always continued to trade as Walter Lilly, the business remained in the Lilly family until 1955 when it was acquired by the Y.J. Lovell Group. That same year the company was appointed to carry out the remodelling of London’s iconic Café Royal.

Fast forward to present day, and with an annual turnover in excess of £80 million, the company continues to grow. And not just with a reputation as London’s premier residential construction specialist, but also as construction experts in the science and educations sectors working on projects including the University of Oxford, Imperial College London and Royal Botanical Gardens, Kew. And finally, as Facilities Managers, maintaining and caring for a portfolio of exclusive and luxurious homes and buildings.

With all its success, the spirit of the family business lives on. Throughout its 90 plus year history the company has had just nine Managing Directors – including the original Mr. Lilly and his son who succeeded him – together with a staff retention record that is the envy of competitors.
