1–4 Marble Arch is a redevelopment project set behind a retained façade, delivering modern office space across the upper seven floors. The scheme also introduces a three-storey retail unit at ground and lower levels, designed to revitalise the western end of London’s main shopping street and enhance its commercial appeal.

1–4 Marble Arch is a redevelopment project that sensitively transforms an existing building while retaining its historic façade, preserving the character of the streetscape. Behind this retained exterior, the scheme introduces a contemporary structure designed to meet modern commercial standards, creating a seamless blend of heritage and innovation in a highly prominent London location.
The development provides new, high-quality office accommodation across the upper seven floors, offering flexible and efficient workspaces suited to a range of occupiers. The design prioritises natural light, modern building services, and adaptable layouts, ensuring a productive and comfortable environment that aligns with current workplace expectations.
At ground and lower levels, the scheme incorporates a significant retail presence, with a major unit extending across three floors. This element has been designed to attract flagship occupiers and enhance the vibrancy of the surrounding area, contributing to increased footfall and commercial activity. The retail offering plays a key role in strengthening the appeal of the western end of London’s प्रमुख shopping district.
Overall, 1–4 Marble Arch represents a carefully considered mixed-use redevelopment that combines heritage preservation with contemporary design. By integrating modern office space with a strong retail component, the project contributes to the ongoing regeneration and economic vitality of this key gateway location in central London.
