RIBA Venues at 66 Portland Place: The Florence Hall

Located on the first floor of 66 Portland Place in London, our largest and most impressive entertaining space – the Florence Hall – showcases the very best of Art Deco and Swedish Modernism.

The Florence Hall, 66 Portland Place

With floor-to-ceiling windows, Art Deco-inspired window etchings, carved stone pillars and sprung wood floors, this versatile space offers a real sense of occasion with a chic backdrop to make photos pop.

The Florence Hall is perfect for conferences, award ceremonies, expos, wedding receptions and fashion shoots – you name it, we can do it in this space.

In spring and summer, guests can step directly from the Florence Hall into our leafy roof terrace, allowing guests to enjoy a moment in our tranquil urban oasis hidden in Central London – all included in your hire. You can even have a barbeque on the terrace to enjoy the sun in style.

Did you know you can pair the Florence Hall with the RIBA Gallery just across the landing?

Make your event sparkle even more by adding the RIBA Gallery today – from wedding ceremonies to conference breakout sessions, the combined spaces are guaranteed to enhance your guest experience.
