Promontorio references walled fortresses for holiday home in Portugal

Casa da Volta has a whitewashed exterior

The whitewashed stone wall that surrounds this holiday home in southern Portugal draws on the region's historic walled fortifications known as alcáçova, to create a feeling of refuge and shelter.

Designed by Promontorio in collaboration with architect João Cravo, Casa da Volta or "Home of Return" is dug into a slope on an isolated and remote site in the hills surrounding the town of Grândola.

Amid this "endless" landscape, the international studio has turned the home inwards, with an almost entirely blank exterior concealing a large courtyard around which living spaces are arranged.

"This typology of a fortified farm is the dominant form of occupation across the Maghreband the Mediterranean, from Roman antiquity and Arab settlements to Fernand Pouillon and Le Corbusier's projects in Argel," explained the studio.

"Poetically, it summons the human need to define a place of dwelling amidst the endlessness of the landscape."

Two small entrances – a corner gateway for cars and a small door for people - lead into the home, where a large planted gravel courtyard is surrounded by three blocks arranged in a U-shape.

At the back of the courtyard is the bedroom block, a row of six simple en-suite rooms positioned off a corridor. These bedrooms both look onto and have direct access to the central courtyard through large glass doors.

A block containing living, dining, kitchen and library spaces runs along the eastern side of the courtyard, opening onto a large terrace overlooking the landscape that leads to a pool.

The third block at the western side of the courtyard provides a garage space and staff bedroom, aligned with a route that leads through the corner gateway for vehicle access.

Appearing as an extension of the boundary wall, the blocks of the home have been given the same whitewashed stone finish, with chalk-painted concrete lintels above windows and openings.

"The roughness of these burnt lime surfaces summons a vernacular and quasi-archaic condition which is nonetheless dismissed by its sheer scale and abstraction," explained the studio.

The home's boundary wall has a textural quality and is topped with pantiles

Both the parapets of the block roofs and the surrounding wall are topped with a single strip of pan tiles, described by the studio as "suggestive of a pitched roof that in fact does not exist."

Inside, brushed concrete floors and white rendered walls create minimal, simple spaces, along with exposed wooden beams that are also painted white.

The living area is designed as an "enfilade" of rooms, with pocket doors allowing the living room, dining room and library to flow together, centred around a fireplace.

Previous projects by Promontorio include the transformation of a 1980s office building in Lisbon that includes a spiral concrete staircase, and a brick-clad, mixed-used tower in the Angolan town of Lubango.

Elsewhere in Portugal, architecture studio Tiago Sousa inserted a brick home into a stone ruin while NOARQ renovated a villa adding bright red detailing.

Architecture practice BIG has revealed its designs for a 12-building AI and cybersecurity campus in Bratislava, Slovakia, that will be visually connected by undulating solar roofs.

Designed as a "tech neighbourhood", the development will contain the headquarters for Slovak internet security company ESET. It is set to be built on the site of a former military hospital in Patronka, in the west of Slovakia's capital city.

The AI and cybersecurity hub will be designed by BIG with Slovak architecture studio Inflow, and engineering studios Buro Happold and Arup. The 55,000-square metre development will have 12 buildings of different sizes and uses organised around a central courtyard and surrounded by landscaped public spaces.

Although individual, detached structures, the campus will be visually unified through its undulating roof. This will rise, taper and dips across its 12 volumes to evoke the nearby Carpathian Mountains.

The campus is comprised of 12 volumes that rise and shorter in height

Buildings located along the outer edge of the campus will house public amenities, while four buildings located at the centre of the campus will house ESET's headquarters and 1,500 employees.

"Rather than a single hermetic entity, we have dissolved the ESET Campus into an urban village of interconnected buildings, framing public paths and urban squares," said BIG founder Bjarke Ingels.

"The diverse cluster of individual pavilions are unified by the undulating solar roofs – forming a single silhouette rising from the forested park-like a man-made addition to the Little Carpathians mountain range."

"Together with the adjacent university, the ESET Campus is set to spark the formation of Bratislava's new innovation district."

The campus will be topped by photovoltaic panels and will be powered by all-electric energy

A central atrium will be placed at the centre of each of the four ESET headquarters buildings, which will be internally lit by skylights. Plants and shrubbery will be incorporated throughout the interior to further the connection with nature.

The development will be topped with a photovoltaic roof, while the exterior of the volumes will be clad in glass and timber.

"The design goal is an entirely electric building, with the vast solar roof and ground source heat pumps creating a significant amount of renewable energy," said BIG partner Andreas Klok Pedersen.

"The use of timber throughout the project ensures the lowest possible carbon footprint."

The courtyard at the centre of the campus will have public amenities including retail, sports, cultural and educational spaces organised around it.

On the north-western side of the concentration of buildings, the campus will open up to a park, which will be landscaped to blend in with the adjoining natural terrain and includes native plants and biodiversity among areas for outdoor working and public use.

The campus is projected to break ground in 2024 and is planned to open in 2027.

Earlier this year BIG unveiled designs for another tech campus made from 12 interconnected buildings. Named Fuse Valley, the development will house Farfetch's headquarters and other technology companies.

Thin tensile structure supports TT_01 table by Poesenvanhiel Architects

TT_01 table by Poesenvanhiel Architects

Ultra-slender legs hold up a vast expanse of metal and glass to form the TT_01 table, designed by Poesenvanhiel Architects as an architectural experiment.

The TT_01 table has what Poesenvanhiel Architects describes as "a symbiotic relationship between rigid and elegant, solid and fragile."

It has a large square glass tabletop laid on a grid of thick crisscrossing steel. Holding up these heavy elements, there are only four thin metal legs, supported by tension cables that stretch to points on the grid.

The TT_01 table is distinguished by its balance of heavy and ethereal materials

Steel discs hold the tension cables in place on the legs, and become an intermediary between the robustness of the steel top and the ethereality of the slender legs.

Poesenvanhiel Architects said it wanted the TT_01 table to have a balanced harmony between robust, rigid elements and those that are gentle and fragile.

The studio also thought of the table as an architectural project, with a structure that could be transferred to a larger scale and work as a covered square.

"We cherish the aesthetic that results from how something is built rather than wrapping something up aesthetically," said the studio. "Because we are architects we see our furniture designs as structural concepts that can be applied at different scales."

"The furniture itself becomes a 1:1 model and at the same time it also serves as a 1:100 research model for an architectural project," the team added.

Poesenvanhiel is a young collaborative architecture and design firm based in Brussels.

Its TT_01 Table was shortlisted for the 2021 Dezeen Awards in the furniture design category.

The category was won by Cecile Manz' Plint table, a flatpack piece held together by leather loops, while other finalists included Yiannis Ghikas' coloured blown-glass Soda coffee tables.

ETH Zurich working with robots to evoke Hanging Gardens of Babylon

Rendering of Semiramis hanging garden structure by ETH Zurich researchers

Researchers from ETH Zurich are building a tall architectural structure that will evoke the Hanging Gardens of Babylon, in a project that involves working collaboratively with robots.

Called Semiramis after the Assyrian queen who is sometimes associated with the ancient garden, the project has been designed with the help of artificial intelligence and is being built with the assistance of four robots.

The structure will feature five geometrically complex wooden pods, each planted with trees and other vegetation. It will reach 22.5 metres into the air and be supported by eight thin steel pillars.

Semiramis is destined for the grounds of Tech Cluster Zug, an innovation centre under construction in Zug, Switzerland. The structure will be erected and planted out in spring 2022.

A research group from ETH Zurich, led by architecture professors Fabio Gramazio and Matthias Kohler, designed Semiramis, with assistance from Müller Illien Landscape Architects and timber construction company Timbatec.

The design involved software and algorithms created by the Swiss university's researchers and applied for the first time on this project.

The algorithm driving the arms coordinates their movements so they don't collide with each other

A machine learning algorithm, developed in collaboration with the Swiss Data Science Center, presented the researchers with a range of design options that fit their inputted requirements.

The options included different pod shapes and spatial arrangements and would highlight how the differences affected individual target variables, such as pod irrigation.

The researchers then tweaked the designs in the Immersive Design Lab, an augmented reality laboratory on the university's Hönggerberg campus.

This used a software developed jointly with ETH Zurich's Computational Robotics Lab, and allowed the researchers to explore and fine-tune the designs together in augmented reality.

The robots work collaboratively with humans, who do the work of gluing the panels together with a special resin

The software would adjust the structure's entire geometry around any change, always generating the most efficient and load-bearing configuration.

"The computer model lets us reverse the conventional design process and explore the full design scope for a project," said Kohler. "This leads to new, often surprising geometries."

The final design the researchers chose for Semiramis is now under construction at the Robotic Fabrication Laboratory at ETH Zurich, where four suspended robotic arms work in tandem to assemble its wooden pieces.

The robots work directly from the computer design, picking up panels and maneuvering them into a precise position, but humans are also integral to the process, as expert craftspeople apply a special casting resin to glue the panels together while they are held in place.

This has benefits for both the workers and the environment, as the craftspeople avoid the work of heavy lifting and positioning, and no resource-intensive substructures are required.

Each of Semiramis' pods is composed of 51-88 wooden panels, and the algorithm calculating the robot arms' movements makes sure they avoid collision.

"Semiramis has been a beacon project for architectural research, bringing together people inside and outside ETH and advancing the key research topics of the present, such as interactive architectural design and digital fabrication," said Kohler.

ETH Zurich is one of the world's leading technology universities and undertakes many complex architectural projects. Its recent work includes the DFAB House, which is entirely designed and built using new digital processes, such as robotic timber construction and 3D sand printing.

Its researchers were also behind the Kitrvs winery in Greece, which has a wall laid using a technology dubbed "augmented bricklaying".

Watch our talk with Ginori 1735 and Luca Nichetto about their new collection of home fragrances

Dezeen has teamed up with Ginori 1735 for a live talk with designer Luca Nichetto about his collection of home fragrances created for the Italian porcelain maker. Tune in live from 4:00pm UK time.

Moderated by Dezeen's founder and editor-in-chief Marcus Fairs, the talk will explore the collection of home fragrances, the first in Ginori 1735's history.

Called La Compagnia di Caterina, or LCDC for short, the collection includes three fragrances in the shape of fragrance diffusers, burnable incense sticks and candles encased in a series of porcelain characters designed by Nichetto.

The containers each feature a character from the the story of the Italian noblewoman Catherine de Medici's move from Florence to France with her court of artisans which included a perfumer.

The forms were informed by masks used in performative Mexican wrestling, graffiti and the illustrations of french graphic designer Jean Paul Goude,

During the talk Fairs and Nichetto will discuss the story behind the collection, the meaning behind the characters and the inspiration behind the pieces.

The fragrances in the collection were developed by Jean Niel, the oldest perfume house in France, founded in 1779.
