Self-Contained Office Building 


Self-Contained Office Building 


The elegant street. The grand façade. The majestic lobby. Nine floors rich with opportunity.

21 Dartmouth Street is a high quality redevelopment by Quadrum, located in the heart of St James’s Park. With approximately 52,000 sq ft of stunning offices, No. 21 fuses an enviable St James’s location with sleek design, smart technology and 10 terraces, including a magnificent new rooftop. The result? An address that intuitively speaks to modern business needs, and commands the appreciation of all who walk through its doors.

No. 21 will be available from Q4 2018.

With the Houses of Parliament and Buckingham Palace so close; 21 Dartmouth Street is surrounded by parks, retailers and restaurants of a quality to inspire.

From its doors, it is a two-minute walk to St James’s Park and its underground station, and only yards further to The Conrad St. James and St. James’ Court. With Victoria’s new restaurant district and flagship stores at hand – plus Sloane Square’s boutiques and nightlife nearby – there is a wealth of diversion to enjoy.
