Memo Architectuur organizes home renovation around spiral staircase

A spiraling staircase and concrete flooring characterize this renovation of a dilapidated row house in Mortsel, Belgium, designed by local studio Memo Architectuur.

Originally consisting of two stacked apartments, Memo Architectuur overhauled the spaces to form a single-family home, adding an additional floor to align the building with the streetscape and maximize interior space.

“The residents wanted a light-filled home with spaces that seamlessly flowed into each other and where as much contact as possible would be encouraged,” lead architect Yasmijn van Winkel told Dezeen.

“The only elements that have been preserved from the existing home are the front facade, the party walls, and the basement,” she continued.

The 240-metre-square home opens up to an entryway, lined with blue ceramic tiles, that contains storage space and a small toilet.

Beyond the centralized staircase and utility area, the ground floor hosts an open-plan kitchen and dining room lit by openings into the home’s south-facing garden.

Green-hued polished concrete flooring, raw concrete and wooden furniture bring cool, earthy tones to the home interior, which is decorated with leafy plants.

“The residents prioritized the use of natural and honest materials to foster a relaxed and homey ambience,” van Winkel explained.

“Despite the vibrant array of colors, a sense of tranquility is achieved by embracing simplicity and straightforwardness in the material palette.”

With a width of 4.75 meters and length of 16 meters, the studio was tasked with drawing light into the darker areas at the center of the home.

To address this, the vertical circulation was relocated to the home’s center to operate as a light shaft, complemented by circular skylights and large openings at the building’s front and back.

A curved, concrete upper floor hosts a living space that overlooks the kitchen area below, with floor-to-ceiling windows both drawing in sunlight and providing views of the garden.

Meanwhile, an additional living space is provided at the front of the home.

On the newly built second floor, the main bedroom opens into a large en-suite bathroom centered by a walk-in shower wrapped by a circular rail and curtain and crowned with an overhead skylight.

Pale blue ceramic tiles extensively line the bathroom and are contrasted by a white bathtub and blue sink fixtures.

The adjoining bedroom overlooks the garden below, while two smaller bedrooms are provided at the home’s front.

Memo Architectuur is a studio based in Antwerp, Belgium, led by Eleni Daelemans and Van Winkel.

Other residential projects recently completed in Belgium include a courtyard house built from materials reclaimed from a demolished warehouse and a refurbished townhouse featuring a skylit atrium.
