London-based architectural practice McLaren.Excell has designed the transformation of the interior of a former factory into a duplex loft on Old Street (London), creating a composition of new, sober spaces that combine contemporary additions with the building's industrial heritage.

The project aims to maintain a close connection to the building's industrial origins by developing spaces with an elegant and polished industrial aesthetic, while also highlighting the pre-existing structure.

This transformation, developed by McLaren.Excell, proposes an industrial design of the spaces in line with the pre-existing architecture to generate a spatially cohesive project. This project spans both floors of the loft, also working to create a spatial fluidity between all the spaces within. The ground floor houses the common spaces, such as the kitchen, dining room, and living room, as well as a small bathroom next to the stairs. The upper floor houses the private spaces, including the bathroom and the master bedroom, which also has a small terrace.

The apartment was stripped back, exposing its wide concrete beams. These richly textured junctions are layered with smooth, putty-colored plaster walls and blackened steel staircases, cabinet fronts, and kitchen cabinets. The factory windows are retained to enhance the connection with the pre-existing architecture. Custom-designed furniture has also been added to the project, such as the blackened steel dining table, dining room lamps, a stone bench and table, and bathroom fixtures.

Project description by McLaren.Excell

Award-winning architecture and interior studio McLaren.Excell has transformed a loft duplex in Old Street to create a series of minimalist spaces celebrating raw materials and industrial heritage.

Wanting to honour the legacy of the former factory’s origins, McLaren.Excell developed an unapologetically industrial design that would allow the structure of the building to shine while creating elegant, curated living spaces. The team stripped back the apartment to expose its vast, structural concrete beams, layering these richly textured junctures with smooth, putty-coloured plaster walls and blackened steel staircases, wardrobe fronts and kitchen units.

This restrained palette – which also features Dinesen Douglas Fir flooring and Nordic Blue stone – is continued throughout the apartment, linking the two floors and creating a pleasingly cohesive flow.

In addition to the architectural framework, many of the statement furniture pieces in the duplex are custom designed. The blackened steel dining table, for example, is a bespoke design from the studio, as are the pendant lights above it. The exquisitely curved Nordic Blue stone bench and coffee table are also custom designed, as are the stone basins in the bathrooms and WC – all of which have been sandblasted to create a uniquely textured surface.

The series of spaces McLaren.Excell has created at The Factory exhibit a sense of visceral materiality that speaks to the building’s origins, while providing intriguing, light-filled spaces for the client to enjoy with family and friends.

Luke McLaren, co-founder of McLaren.Excell, commented: “Our aim with this project was to celebrate the building’s past while homogenising the space by selecting a really simple palette. Essentially, we picked two materials – Clayworks plaster finish and Dinesen Douglas Fir floor boards – and ran them throughout the apartment. We then added blackened steel and Nordic Blue stone elements. This consistency makes the transitions from space to space feel effortlessly smooth and fluid. A former Nineties loft apartment now has a pleasing purity to it that celebrates the building’s heritage while providing inviting and enriching living spaces.”

McLaren.Excell is a London-based architectural practice founded in 2010. It is co-directed by Luke McLaren and Robert Excell. The practice focuses primarily on private residential and commercial projects.

Since 2010, the practice has undertaken a wide range of projects in a short time, building a reputation for producing buildings with a serene authority and a subtle sense of place. The practice has become a space for ongoing research into how to translate original ideas into built reality, a process driven by a genuine passion for good design.

Luke studied at Cambridge University, the Royal College of Art, and London Metropolitan University. In 2005, he joined the award-winning Jamie Fobert Architects, where he worked on the new Tate Gallery in St Ives, in addition to several private residential commissions both in the UK and abroad. In 2007, he founded his own practice, where he focuses on residential projects ranging from terraced house renovations and extensions to rural conversions and adaptations. Luke's specialization lies in the detail of construction and understanding how a design can be constructed and fully resolved. This stems from a deep interest in making and perfecting things through the construction of objects, carpentry, and buildings, which has allowed him to develop a profound understanding of construction.

Robert studied at Kingston University and specializes in the remodeling and repurposing of existing buildings and spaces. After leaving Kingston, he joined Powell-Tuck Associates, where he worked on several bespoke residential projects in southwest London, both new builds and refurbishments. In 2007, Rob joined D_Raw Associates, where he gained a more specialized focus on commercial work in the retail and leisure sectors. He completed several retail projects for the clothing franchise Reiss, as well as restoration projects for Fenwick (Bond & Brook) and The Gondola Group. During this time, he also worked on several private residential projects in Marylebone, St. John's Wood, and Hampstead. Rob possesses an instinctive ability to see the potential in an existing structure and, thanks to his typically lateral approach, often produces innovative and unexpected designs that challenge preconceived ideas.

The studio has garnered several awards from Hunts Green Barn in recent years, including Architect of the Year and Residential Transformation of the Year at the British Home Awards 2022 and Best Contemporary House and Best Interior Design at The Daily Telegraph Homebuilding Awards 2022.
