Montagu Square

The listed apartment conversion project in central London demonstrates Whistlers’ expertise in transforming historic buildings into modern, functional homes while preserving heritage features. From the outset, the team carefully planned each intervention to maintain structural integrity and protect listed elements.

In phase one, the team stripped the ground-floor apartment and installed new mechanical and electrical services. Simultaneously, they restored and protected listed interiors, reconfigured layouts, and incorporated former common areas into the residence. As a result, circulation improved, and the internal flow became more efficient. Structural openings were added where necessary, further enhancing connectivity and functionality.

Phase two involved opening the floor structure to install a new staircase connecting the lower ground floor. This created additional spaces, including a bedroom, bathroom, and a media room. Moreover, the media room was formed from an existing vault, requiring specialist excavation beneath the adjacent highway. Careful structural solutions ensured safety, compliance, and minimal disruption to neighbours.

Throughout both phases, Whistlers balanced heritage preservation with contemporary living. They introduced natural light, high-quality materials, and bespoke joinery while maintaining elegance in every room. Consequently, the apartment now combines historic character with modern comfort.

Ultimately, this listed apartment conversion highlights Whistlers’ ability to deliver complex refurbishments in central London. By combining detailed craftsmanship, structural expertise, and careful planning, the team created a bespoke home that meets modern lifestyle needs without compromising its heritage. In addition, the phased approach allowed efficient execution, reduced disruption, and maximised both functionality and aesthetic quality.
