Vester Voldgade Attic Copenhagen Apartment by David Thulstrup.

For Copenhageners, chasing light is part of their daily preoccupation, no matter the season. After all, light has a profound impact on how one feels. For his latest residential project—a 150 square meter attic apartment of an 1890s building in the centre of Copenhagen—David Thulstrup prioritised implementing a greater sense of light and space through a range of bold architectural interventions.

To accommodate the client’s wish for a bright and spacious home, Thulstrup focused on interventions that would support such transformation. “By opening up the volumes of the living spaces both vertically and horizontally and using quality materials, I re-introduced a feeling of calmness and balance into a space that was marked by low ceilings and limited natural light”, says the designer.

The owner’s acquisition of the attic space above the apartment welcomed a heroic double-height living area with exposed rafters that form a sculptural connection between the two levels. “The key architectural intervention”, Thulstrup explains, was to “intercept the pitch roof structure, extend the kitchen space and add a roof terrace that is exposed to (sun) light from morning to evening. These newly established volumes allowed all interventions to celebrate existing features, and to simultaneously inject a sense of time.”

To enhance the new sense of height, the building’s original arched windows at the centre of the living space were elongated. For a bigger impact and more room for natural light, walls were adapted to extend the living space in all directions without any dividers or doors. Additionally, large bi-folding glass doors open off the combined kitchen and dining space to a second terrace which feels like an extension of the room.

“It felt necessary to implement a neutral colour scheme to create volume and enhance all historic features such as the rough timber beams. This paired back approach was able to transform the space into a simple but elegant and warm home. My favourite feature to convey this sense of permanence and belonging is the dining nook with a built-in bench and upholstered cushions in creamy natural leather”, adds Thulstrup.

The open-plan kitchen, featuring Plate—Thulstrup’s latest design for Reform—compliments the dining nook, although it might not seem like it at first glance. However, the simplicity of the space enhances the softer qualities of the crafted metal finish and invites the hand-brushed aluminium to work its full potential.

After experiencing Thulstrup’s interior concept for Noma, the client admired the application of natural local materials such as Dinesen Heart Oak planks and Bornholm granite. To honour the value of locality, similar materiality can be found throughout the apartment—not only for floors and walls but also for custom-made furniture implemented as architectural elements. The built-in sofa bench that runs the length of one wall, an in-built dining bench as well as the 200-kilogram glazed lava stone coffee table are only a few examples.

As an ode to his own design principles, Thulstrup added a spiral staircase made from glass-blasted steel and a custom yellow-pated zinc finish mainly used for industrial purposes. “It’s a striking yet thoughtful sculptural gesture that ties together the two floors. The special finishing interacts with the abundance of light in a way that creates beautiful reflections with dashes of green, pink and blue.” The stairs lead to a reading nook and the new roof terrace with a spectacular view of the city.
