An addition and renovation of a weekend house on Torö, an island in Stockholm's southern archipelago. The existing building is a catalogue home from the early 1970s, standing in a mossy clearing on the highest point of the island.

A new volume extends the northern gable, every interior space was reprogrammed, and a new roof was built, 93 m² in all, including the 18 m² addition.

Awarded Ung Svensk Arkitektur 2023. The jury cited a loving approach to an often overlooked category of Swedish folkhem architecture that avoids nostalgia, understanding the qualities of what is already there and blending them with contemporary additions.

A permanent stage for the park in Tibro, built on a municipal budget of 300,000 kronor. Ordinary timber framing is clad in fibre-cement sheets, hand-painted as faux marble by students at the town's craft academy, so the structure reads as a stack of oversized quarried blocks.

Because the marbling is painted rather than cut, the veining can be bolder and stranger than any stone would allow. It is the first of fifteen speculative proposals from the Tibro Train Tracks study to be built.

Alma Löv Museum of Unexpected Art.

A beginning, made on the meadow across the little stream. A place to call home, built around an interest in ornament. Can ornament add something to a home?

A hands-on process where the sketching happens in direct contact with the material and the surroundings, where exploring is the point and the point is not an ending.

Drawing on Finnish sauna culture and a love of form, craft and durability, a sauna jetty proposed for the shoreline around Dalénum and Larsberg. A place for the people of Lidingö to unwind and take part in what bathing does for you.

There is something magical about a sauna, a place that gives you room to breathe away from the obligations of the day. In a society where we are more often absent than present, somewhere to relax and be in the moment is worth building.

A proposal to turn Järvafältet, the under-used green wedge between Stockholm's north-western suburbs, into a genuine city park by wrapping a new timber district around its edge. Around 12,000 homes and 140,000 m² of workspace step up from allotment-hut scale to towers along an extended Rinkebystråket with a new tram line.

The stepped roofs are treated as public ground, so the park climbs over the buildings and returns to the landscape on footbridges. A raised Granholmstoppen adds ski slopes, and a widened stream becomes a swimming lake.

A set of small interventions arguing that a city built on islands barely touches its own water. Swimming rafts are scattered into neighbourhoods with no bathing nearby, compact cold bathhouses with saunas and water stairs line the quays, and football pitches float at Liljeholmskajen, Söder Mälarstrand and Hornsbergs strand.

The connective move is to hang walking and cycling routes from the foundations and arches of bridges that already exist. Årstabroarna, Västerbron and Tranebergsbron all gain one, with a new opening bridge between Masthamnen and Saltsjökvarn.

A densification study for Marieberg on Kungsholmen, tied to a proposed metro line between Fridhemsplan and Liljeholmen. The district's height ceiling comes from Bromma airport's flight paths; with Bromma due to close, the proposal removes that constraint and sets new towers alongside Marieberg's existing landmarks.

Around 90,000 m² of floor area, roughly half of it some 4,500 flats over ground-floor shops and restaurants. Rålambsvägen gives up half its width to a linear park.

Two mall showrooms for an independent electric-vehicle charging operator. The company sells a service rather than a shelf of products, so the shops are built as oversized shop windows, readable in a single glance from the walkway.

Four illuminated pylons stand in a quarter circle facing the mall, one for each kind of customer: private owners, housing co-operatives, offices and public bodies, each with a surface to touch and test. Lit panels are paired with ash; meeting space and back office sit behind.

Two additions to Sommarnöjen's c/o series of prefabricated summer houses. Buyers usually own remote plots, so c/o 40 arrives as two volumes sized to Swedish road transport limits and is craned together on site, one holding kitchen, bathroom and bedrooms, the other the living room. c/o 50 repeats the arrangement with an extra bedroom.

The work also meant auditing every detail and drawing across the existing range, visiting the Latvian and Estonian factories that build the houses, and partly automating the drawing production so each house generates its own document set.

Fluffy Encounters joins the 2025 Copenhagen Architecture Biennial with a combined workshop and exhibition dedicated to the possibilities of wool in architecture. The project explores how this ancient fibre, often discarded today, can support slow, circular, and locally rooted material practices.

Through hands-on making and curated displays of Nordic collaborations, visitors encounter wool at different stages: raw, processed, reworked, and reimagined through innovative products and value-chain efforts.

The workshop invites participants to sort, felt, shape, and engage directly with wool, while the exhibition contextualises these processes within broader cultural, ecological, and architectural conversations.

Together, they highlight how returning to materials and their rhythms can help mend fragmented resource flows and cultivate an architecture grounded in care, collaboration, and slowness.

Drömmarens Malmö (Malmö Dreaming) is Fanfaluca Collective's contribution to the architecture festival Malmö in the Making. The project consists of two parts, a film that examines the stories of Malmöiter (people of Malmö) and their connection to their city.

The second complementary element is a built installation where you can take part in the film in the public space. The contribution aims to invite a dreaming about our relationship with the city by conveying different descriptions and perspectives of Malmö.

Within dreaming, everything is possible. Hopes, reflections and relationships float to the surface. Together, we want to create a moment of shared travel in thought, through the spaces of the city.

Like the transparent willow leaves that make up the eel in its first stage of life, the viewers, brought together by the currents of life, become aware of their senses. The play between the most basic elements of our surroundings: light, water and sound is embodied by a recurring event, the dripping of water.

A meditative state and a stillness, softly entwined under a water surface. The drops are caught by a vessel which in turn emits a sound. A music of "drip drop" and resonance from the walls of the vessel is staged.

A two-day tufting workshop at Aavistus, an audiovisual festival in Helsinki, made together with Jonas Johansson. Ten participants tufted their own cultural canon using the exquisite corpse method: two groups of four each designed and tufted a square, then passed it on for the next group to respond to without ever seeing the whole.

The result is 24 tufted squares covering 140 × 210 cm. For the workshop Rose designed and built a custom modular tufting frame that expands to 2 × 4 metres and folds down into a sports bag.

An autobiographical one-man show by the dancer Danne Dahlin about living with bipolar disorder. Rose designed the scenography and, with Jonas Johansson, the video; the lighting was kept deliberately plain so the room stays with Danne, who carries the whole piece alone.

Dahlin was headed for a career in dance when the illness took hold. The piece looks back across nineteen years: a first manic episode in New York, the stable years that could no longer hold it back, and being found in Los Angeles in 2018 surrounded by police with drawn weapons.

It premiered at Kilen, Kulturhuset Stadsteatern, in November 2024, sold out, and was staged a second time.

A vase made for a single flower. Tulips keep growing after they are cut, so the vessel has to hold something that rearranges itself over the days it stands there. The vase stays still while the flower moves.

The form is an interpretation of the Delft pyramid, the tiered tulip vase of the seventeenth century, when a single bulb could cost more than a house.

A countdown campaign by Codesign Research Studio to 20 January 2020, the day the UN Convention on the Rights of the Child became Swedish law. Not an exhibition but a year of street actions, school workshops and guerrilla activism, gathering work on children's spatial rights into one public campaign.

It opened on 20 January 2019 with an action on Drottninggatan where the architects wore capes built from their own printed material. Rose's was assembled from information cards carrying the articles of the Convention, so the costume was also the handout, and incidentally avoided the permit a stationary stand would have needed.

Alongside it ran the Palla ta plats stool workshop for Kulturnatten, and an action at Almedalen where bicycles carried the line that a fifth of Sweden's population is under eighteen and none of them are consulted about the city.

Photographs of buildings and the places between them, made alongside the architectural work, often on site visits, and often of things that will not stay as they are.

The same eye did the documentation work: as in-house photographer at Codesign she shot the studio's finished interiors, among them the offices for NoA, The North Alliance, and the workshops and street actions of its research studio.
