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. We operate as a not for profit member’s organisation that strives to improve the world through engineering.

The building, built in 'Queen Anne style', the height of fashion at the time, was designed by architect Basil Slade. It 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, we 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.

Our largest space is our Lecture Theatre, located on the ground floor, which can accommodate up to 210 guests. Hire of the Lecture Theatre comes with a technician for the day to make sure all A/V runs smoothly. Below the Theatre we have the Marble Hall, built in the style of a Venetian palace and finished with Piastraccia and dark Grande Square flooring. This is the catering space for Lecture Theatre Events, and can also be hired alone to hold evening receptions for up to 210 guests, or dinner for 90.  

The 12 meeting rooms throughout the venue celebrate the lives of well-known and recognised mechanical engineers, and their achievements.

Last but not least, the Library. Built in the Elizabethan Style, clad in marble and warm oak with stunning views over the park, the Library is open to the public during the week and can hold evening receptions and dinners.
