William's experience showcases a broad range of complex property and corporate transactions. He advised on the acquisition of a children's day care business by a pension fund, utilizing a combination of share purchase and a sale-and-leaseback arrangement. His expertise includes managing challenging title, overage, and covenant issues during the sale of a public house business.

He acted on the purchase of a regional shopping parade featuring nationally known "anchor" tenants. In corporate-property matters, he advised on the sale of serviced offices via a sale of the client's issued share capital, and managed a prolonged sale of a restaurant business where an overseas landlord imposed complex conditions for consent to assign based on the buyer's status. He successfully worked on the sale of parts of a building set to different purchasers, involving refinancing via bridging finance and coordinating the completion of sales and the release of covenants by the local authority. For an established client, he acted on the sale of 10 flats by granting 999-year leases on a single repurposed building, which included developing the necessary sales pack for a smooth conveyancing process.

Additionally, he has advised numerous clients on commercial lease renewals utilizing the Landlord and Tenant Act 1954 to secure optimal terms. Over a five-year period, he assisted a major travel company with various office moves, and for a "night life" client, he handled a series of site acquisitions and disposals spanning over 10 years.
