Venue at a glance
De Morgan House is a conference and meeting venue operated by the London Mathematical Society in a Grade II listed Victorian townhouse overlooking Russell Square in Bloomsbury, central London. The main conference suite sits on the ground floor, with an additional executive boardroom on the second floor. The venue combines period architecture, natural daylight, and a quieter academic atmosphere with practical central London access.
It is particularly well suited to board meetings, workshops, training days, small conferences, academic events, charity meetings, and professional gatherings where buyers want something more characterful and values-led than a standard hotel meeting room. As a listed building it retains original Victorian features including fireplaces, period proportions, and garden-facing rooms, and every booking supports the charitable mission of the London Mathematical Society.
Why choose this venue
The venue offers a published 20% discount for charities and non-profits, with 40% discounts for mathematical charities. This is unusual in central London and makes it particularly attractive for associations, learned societies, NHS organisations, and third-sector groups.
De Morgan House retains original Victorian features including fireplaces, period proportions, and garden-facing rooms. Buyers often choose it because it feels calmer and more distinctive than a corporate meeting suite.
The Hardy Room opens directly onto a private rear garden, which can also be hired alongside the catering area. Outdoor breakout space is relatively rare in Bloomsbury meeting venues.
Russell Square Underground Station is approximately three minutes away on foot, while Euston, King's Cross, and St Pancras are all walkable, giving strong national rail accessibility without requiring overnight stays.
The venue is owned and operated by the London Mathematical Society, with revenue supporting mathematical research and collaboration — a meaningful differentiator for organisations with social procurement or ethical sourcing policies.
