41 Portland Place

Located in the heart of Marylebone, just moments from Regent’s Park and Oxford Circus, 41 Portland Place is a Grade II* listed Georgian townhouse offering a refined and character-led setting for corporate events, private dining and receptions. Blending historic architecture with modern event infrastructure, the venue provides a distinctive alternative to more conventional London event spaces.

Set across multiple floors, the venue offers a series of elegant rooms that can be used individually or combined, allowing events to scale while maintaining a sense of intimacy. From panelled reception rooms and heritage features through to a purpose-built auditorium, the space supports a wide range of formats including conferences, presentations, networking receptions and seated dining.

Catering is delivered in-house, with a focus on seasonal, well-executed menus designed for both formal dining and more relaxed event formats. The layout of the building naturally supports guest flow, with clear separation between reception, dining and presentation spaces, making it particularly effective for structured corporate events.

Key features include:

• Capacity for up to 220 guests standing

• Tiered auditorium seating up to 110 theatre-style

• Multiple interconnected event rooms across several floors

• Grade II* listed interiors with period features

• In-house catering and dedicated event team
