An all-lilac kitchen and bright geometric storage solutions feature in this colourful Stockholm apartment renovation by local studio Westblom Krasse Arkitektkontor.

The two-bedroom apartment, which is housed within a 1980s prefabricated concrete building in southern Stockholm, was transformed by the architecture studio for a family with four-year-old twins.

As part of the renovation, Westblom Krasse Arkitektkontor created a number of space-saving storage solutions. For example, the original floor plan featured an enclosed storage space in the middle of the apartment.

The studio converted this into a trio of smaller storage units for the living room, the kitchen and the pantry. This was achieved by decreasing the size of the hallway but maintaining a corridor to the open-plan living room and home office.

"The original floor plan was robust and quite deep, with a load-bearing wall separating the living room and bedrooms into two halves," studio co-founder Jesper Westblom told Dezeen.

"We didn't want to close off the spaces by making tiny enclosed rooms, but rather make light additions. The aim was to use small adjustments to make the rooms more defined spatially."

A palette of hues created from a mix of the three primary colours – red, blue and yellow – features throughout the home, with the colours offset by white-painted flooring.

Westblom Krasse Arkitektkontor also chose a combination of pine wood and red medium-density fibreboard to create bespoke joinery and furniture.

The kitchen was finished in a floor-to-ceiling shade of bluey lilac that also characterises a built-in geometric bench next to the dining table and a tall cupboard concealed behind a "secret door".

A large bookshelf divider decorated with organically shaped vases creates a partition between the open-plan living room and office area, with a burnt-orange shelving system providing extra storage.

The office area can also be cordoned off with a curtain to create extra peace and quiet.

The architecture studio's Elephant sideboard – a chunky blue table that owes its name to its sturdiness and colour – was also included in the living space.

The family's twins share one bedroom, which can be entered through two tall and narrow doors, adding a playful touch to the apartment.

Small windows were also added above these doors to increase the natural light in the home.

Inside the twins' bedroom is a sleeping zone and a play area, which are separated by a low wall to create a clear delineation between the two spaces.

"One of the biggest – and most fun – challenges was to make every single space useful and effective and make room for both play and recovery," reflected Westblom.

Westblom and Robin Krasse founded their eponymous Stockholm-based studio in January 2021.

The firm previously completed the interiors for a local hair salon, which takes cues from architect Carlo Scarpa's geometric designs and the muted colours of 1920s swimming baths.
