One Birdcage Walk

One Birdcage Walk is the purpose built home for the Institution of Mechanical Engineers, a Royal Chartered Institution that was formed in 1847 by George Stephenson.

The building was designed by architect Basil Slade and was officially opened in 1899 when at the time, it was fitted out with state-of-the-art features such as a telephone, one of the first hydraulic lifts and synchronome master clock which used electrical impulses to ensure that all clocks in the building kept uniform time.

Located just minutes from the Houses of Parliament, Horse Guards Parade and Treasury, they are a 5 minute walk from Westminster and St James’s Park tube. The building, which overlooks St James’s Park is regarded as one of the finest examples of traditional architecture in Westminster.

The grand Elizabethan style Library is clad in warm oak and has stunning views over St James’s Park, perfect for evening drinks receptions and dinners, providing a real ‘wow factor’ for guests.

The unique Venetian palazzo-styled Marble Hall and adjoining Gallery are perfect for evening drinks receptions for up to 200 guests.

Reception capacity – 200

Dinner capacity – 120
