Hallam Street – Complete Luxury Flat Remodel & Refurbishment
This project comprised the complete remodelling and refurbishment of a flat on Hall Street, Marylebone, within an exceptionally old and characterful building in the heart of central London. Delivered over many months, the works were technically and logistically complex, requiring meticulous planning due to the property’s location on a busy main street and the inherent constraints of working within a multi-occupancy historic structure.
The scope of works included a full reconfiguration of the internal layout, enabling the space to be reimagined for contemporary living while maximising flow, light, and functionality. A comprehensive interior renovation was undertaken throughout, incorporating new flooring, a bespoke kitchen installation, and the creation of a new bathroom. The project also involved resolving complex plumbing and servicing challenges, carefully integrating modern systems within the fabric of the existing building without compromising its integrity.
Central to the success of the project was close collaboration with the property developer. Through a detailed and considered design process, his vision of a refined, elegant residence was brought to life. The resulting interior is modern, fresh, and luxurious, yet remains in harmony with the heritage and architectural character of the historic building — a sophisticated urban retreat that balances timeless craftsmanship with contemporary comfort.
The transformation also delivered a tangible financial impact, increasing the property’s market valuation from £600k to £900k, reflecting the quality of design, materials, and execution.
