    Paulo Merlini Architects creates concrete spiral walkway inside Porto office

    A spiralling concrete walkway and a storage wall filled with colourful ceramics are the standout features in this office for E-goi and Clavel’s Kitchen, designed by Paulo Merlini Architects.

    The three-storey building is the headquarters for two companies: Clavel’s Kitchen, which creates digital content for brands in the food sector, and email marketing provider E-goi.
    A spiralling concrete ramp connects the three floorsPaulo Merlini Architects designed the 2,800-square-metre workplace to be functional and flexible, but to also feel playful and creative.

    “One of the most important issues in designing a company’s headquarters is to create a space that expresses and is in line with the corporate culture,” said the studio.
    “Both E-goi and Clavel’s Kitchen present a rather informal type of management, although extremely professional, and asked us for a space that would express that – a fluid, equal, heterogeneous and unpretentious space.”
    A skylight illuminates the walkway from aboveThe building is made of two structures – one preexisting and one new – which join together.
    The concrete ramp forms the natural heart of the newly connected interior, providing access between floors while also functioning as a meeting place for staff.

    Slender vertical bars create a balustrade, while adding to the sculptural appearance of the spiral.
    There’s also a skylight above, which allows natural light to filter down through all three floors.
    A storage wall is filled with objects used in photoshootsThe colourful storage wall, located on the first floor, provides a striking backdrop to the spiral.
    Built from wood and with a backdrop of clear glass, this huge shelving unit is filled with cooking equipment, crockery and tableware, used by Clavel’s Kitchen for photoshoots.
    These elements are organised by colour, creating a rainbow effect.
    The photography studio benefits from north lightThe photography studio is positioned directly in front of this wall, behind the glazed north-facing facade, so that it can benefit from natural light with minimal shadows.
    Paulo Merlini Architects said this is “the best light for the type of function it offers since, reflected by the sky, it offers low-contrast lighting, remaining relatively constant during the day”.
    “Wooden boxes” organise the interior layoutOther spaces in the office include a dining room with enough space for 100 people to eat together along with a mix of formal and informal meeting rooms and video-call booths.
    These spaces are organised by a series of “wooden boxes”. Some of these are complete volumes that contain entire rooms or booths, while others are made up of partition walls or ceiling surfaces.
    Meeting rooms are housed within these wooden volumesOne box incorporates three house-shaped openings, with banquette seating and tables built in, while another features curtains and beanbags.
    “It is the distribution of these boxes throughout the space that defines all the spatial dynamics,” said the studio.
    Spaces are designed to be flexible and fun”By distributing these functions in a heterogenic way throughout the space, and by mismatching these elements in a kind of organised chaos, we guarantee spatial versatility and create a series of nooks and crannies that allow several kinds of appropriation,” it continued.
    “We guarantee ample spaces where the interaction between co-workers takes place with great naturalness, and more discrete spaces where you can read a book, relax, or even have a more informal meeting.”

    Laurent Troost turns abandoned Brazilian building into co-working venue

    Workspaces look upon a mini jungle in this 125-year-old brick building in Manaus, Brazil, which has been thoughtfully revitalised by design studio Laurent Troost Architectures.Called the Cassina Innovation House, the project entailed the adaptive reuse of a dilapidated historic structure in Manaus, the capital of the state of Amazonas.

    The building, which now serves as a co-working venue, is located in an emerging digital district within the city. Its name was selected through a public vote organized by the municipality, which owns the building.
    Its original structure was constructed in the late 1890s to house the luxurious Hotel Cassina, owned by an Italian man named Andrea Cassina.

    The building was abandoned and taken over by vegetation

    After a financial crisis devastated the region, the building became a spot for gambling and prostitution called Cabaré Chinelo.
    It closed around 1960 and began to deteriorate, according to local firm Laurent Troost Architectures.

    Over the decades, the interior crumbled and vegetation overtook the building, resulting in a striking visual image that the architect wanted to honour in some way.
    Troost said that artists and designers have long been intrigued by ruins, citing figures such as Piranesi, Gordon Matts-Clark and Robert Smithson.

    Greenery and exposed walls evoke the building’s crumbling grandeur
    “The beauty of the ruin’s imperfection raises interest and questions, and invites reflection on the past and the action of time and man in the city – and on heritage buildings in general,” the architect said.
    The team opted to preserve the building’s exterior brick walls, along with the remaining foundation walls made of stone. It decided to reconstruct the interior using a prefabricated steel system, and to add a glazed volume atop the roof.

    The staircase is open to the sky
    The building now totals 1,586 square metres, spread across four levels.
    The facades were cleaned, and great care was taken to preserve original elements such as a plaster made of pigment from red sandstone powder. On the eastern elevation, new shading devices help mitigate solar heat gain.

    “The east facade, hit by the rising sun, has received contemporary frames with tempered glass fins to create a ventilated, double-skin facade that keeps the heat out,” the studio said.

    Glazed walls overlook the gardens
    Inside, the team used the steel system to form new floors and a stairwell, along with space for an elevator. The system stands independent from the building’s outer shell.
    “We have basically constructed a squared tower with four new columns,” Troost told Dezeen. “The perimeter beams of our structure have allowed us to anchor the existing facades to avoid the collapse towards the street.”

    There are a variety of co-working spaces available
    The metal system was prefabricated off-site, which sped up the project timeline.
    Moreover, it reduced the number of on-site construction workers, which helped with social distancing – an important factor given that Manaus was hit hard by the coronavirus, the studio said.

    Greenery is visible through areas of glazing
    A tropical garden was planted in a triple-height space just inside the front door.
    “The building houses an exuberant garden behind the main facade, creating its very own microclimate,” the team said. “A walkway crosses the void over the garden, reminding one of Manaus’s intrinsic reason for being: the Amazon rainforest.”

    There are desks and meeting rooms in the offices
    Adjoining the stairs are open rooms with glazed walls that provide views of the interior garden. A range of flexible spaces can be found within the building, including work zones, meeting rooms and training areas.
    The rooftop addition holds a restaurant with sweeping views of the city’s historic centre and the Rio Negro. Large roof overhangs clad in ipe wood – also known as Brazilian walnut – help shade the structure.

    The team noted that the building’s design allows for physical distancing and the circulation of fresh air, which will remain important considerations in our post-pandemic world.
    Born in Brussels, Laurent Troost has worked in various countries and taught at several Brazilian universities.
    Other projects by his studio include Casa Campinarana in Manaus, which won a 2019 Dezeen Award for Rural House of the Year. The concrete house features outdoor living areas and a swimming pool that are elevated above the forested surroundings.
