Our story

Playing our cards right since 1924

In 1924, Walter Gent Lilly won the freehold to a London builder’s yard in a card game, unknowingly laying the foundations for a legacy. Priding his business on quality and integrity, he embraced the building trade and became an overnight success.

Fast forward to today, where Walter Lilly and sister company Size Group operate together under Wize Holdings — a distinctive group of outstanding businesses dedicated to delivering the highest standards in specialist construction, craftsmanship, and maintenance.

We’re taking on our largest, most ambitious projects yet, guided by the same family spirit that shaped our humble beginnings. Along the way, we’ve fostered lasting relationships with repeat clients built on trust, a reflection of our commitment to collaboration, reliability, and personalised care.
