en.Wedoany.com Reported - UK-based Hale Brown Architects has submitted a planning application to Westminster council for the refurbishment and expansion of an office building in London's Marylebone area. Originally designed by Squire & Partners, the renovation plan, developed for developer 3RE, includes replacing the facade and adding two floors to the eight-story building at 11 Baker Street.

The existing building, covering 7,000 square meters, was constructed in 2011 by McAleer & Rushe and features a full glass curtain wall with floor-to-ceiling windows. Hale Brown Architects noted that this design has led to overheating issues in the building. The ground floor also includes a covered colonnade, which the firm believes lacks appeal outside retail hours and may encourage anti-social behavior.

The renovation plans include expanding the colonnade to a height of two floors to enhance its quality as a public space. The building's facade will be replaced with thermally efficient brickwork, reducing the glass area by approximately one-third. The existing seventh floor will be demolished and rebuilt, with the new seventh and eighth floors adopting the same floor plan and facade design as the rest of the building. The new ninth and tenth floors will be clad in bronze metal finishes. The ninth floor will be set back, featuring private roof terraces, while the tenth floor will include a public roof terrace and a rooftop pavilion space.

The project's design team includes lead architect and designer Hale Brown Architects, planning consultant PMV Planning, project manager Francis Hunter, structural engineer Taylor Boyd, and mechanical, electrical, and sustainability consultant Wallace Whittle.
