Tucked behind the leafy expanse of St James’s Park and offering sweeping views of Buckingham Palace, the Mall, and Green Park, Lancaster House is one of London’s most prestigious and picturesque venues for summer entertaining. With its grand architecture, storied history, and exceptional outdoor space, it’s no wonder that Lancaster House has become a sought-after destination for garden parties that blend sophistication with seasonal charm.

A Garden Like No Other
The Lancaster House garden is a rare gem in central London. Its scale and seclusion offer a unique sense of privacy, making it ideal for high-profile receptions, corporate celebrations, and elegant soirées. The terrace and garden can accommodate over 450 guests, with the option to install a marquee for added flexibility.
Whether you're planning a champagne reception under the summer sun or a twilight gathering with ambient lighting and live music, the garden provides a stunning backdrop that elevates any occasion.
A Venue Steeped in Prestige
Beyond its gardens, Lancaster House boasts a series of opulent state rooms, including the Long Gallery, Music Room, and State Dining Room, each offering a seamless transition from outdoor to indoor entertaining. The venue’s rich political and cultural heritage adds a layer of gravitas, making it a favourite for diplomatic receptions, fashion shoots, and film productions alike.
