Kei Kaihoh Architects forms snow-cooled rice warehouse from local cedar

Japanese studio Kei Kaihoh Architects has completed a timber-framed storage facility in Joetsu City that offers rice farmers a way to refrigerate their harvest without relying on gas or electricity.

Instead, the Yukinohako facility is naturally cooled using snow – an abundant local material in this mountainous part of Niigata Prefecture, surrounded by ski resorts and terraced rice paddies.

With the aim of creating a model that could be cheaply and easily replicated across the prefecture, Kei Kaihoh Architects constructed the two-storey structure using local cedar instead of reinforced concrete or mass timber, which would have to be shipped in.

The studio hopes that Yukinohako, which is Japanese for “treasure chest of snow”, can encourage locals to find a new appreciation for snow and its natural cooling abilities, rather than just seeing it as a burden.

“If inexpensive snow rooms can be realised, farmers will be able to easily build snow rooms in both new construction and renovations, increasing momentum for snow utilisation rather than snow removal,” Kei Kaihoh Architects said.

“By doing so, we can love snow, which has been an obstacle to people’s lives, costing them money and effort to dump it into the ocean, and was not well-liked by the local population.”

Yukinohako replaces a reinforced concrete warehouse cooled by an emissions-intensive air conditioning system, which was damaged by a fire during renovation works in 2017.

The gabled building stretches over two storeys and is held up by a system of braced timber columns that are supported by auxiliary beams.

This allowed Kei Kaihoh Architects to use local small-diametre cedar wood rather than having to ship in mass-timber members.

At the centre of the building is a double-height, 159-square-metre warehouse, which takes over the majority of the ground floor. It sits alongside a small temperature-control room and a reception.

The storage space itself is split in two, with one side holding up to 90 tonnes of snow that is piped into the building using an automatic snow blower and an inlet on the east side of the building.

The other side can accommodate around 30 pallets or one tonne of rice and 200 kilograms of vegetables.

In order to maintain airflow, the two halves of the space aren’t separated by a wall but by steel containers filled with snow, while an auxiliary fan on the ceiling circulates cold air from the snow into the food store.

A maintenance bridge runs across the double-height space to provide an overview of the warehouse and connects to a break room on the second floor.

To ensure the interior stays as cool as possible, Kei Kaihoh Architects installed insulation panels across the walls and ceilings of the warehouse, creating an air-tight envelope.

Even the forklift trucks used to transport palettes of rice are powered by batteries instead of engines to avoid emissions and reduce the need for mechanical ventilation.

The studio also constructed an external corridor that runs along three sides of the building, creating a double facade to prevent solar radiation from reaching the inner insulated wall.

Taken together, Kei Kaihoh Architects says these measures help to keep the warehouse at a consistently low temperature while generating a fraction of the emissions as a traditional air conditioning system.

“In low-temperature warehouses, the storage method involves the constant use of electric air conditioners to keep the temperature at 10 to 20 degrees Celsius,” Kei Kaihoh Architects told Dezeen.

“On the other hand, at Yukinohako, the temperature is kept at zero to five degrees with only the cold air of snow and the humidity is kept high.”

Aside from providing a covered walkway around the building in winter, the external corridor also provides a space to enjoy views of the surrounding nature.

Strategic openings in the facade frame views of the snowy landscape while slatted sections allow light to filter in alongside the sounds of the Oguro River, which rushes along the back of the warehouse.

“We aimed to create a place where people could take pride in farming in the snow country,” the studio said.

The building’s timber structure was pre-cut and assembled at a nearby factory before being sent to the site, catering for quick and easy construction despite the region’s heavy snowfall.

“The processing and storage of prefectural cedar timber is done in Joetsu City, minimising transportation costs and fuel consumption,” the studio said.

To protect the wood from water and inclement weather, the building’s exterior walls are finished in a glass coating, which Kei Kaihoh Architects says was also used in Kengo Kuma’s Japan National Stadium.

Yukinohako has been shortlisted in the sustainable building category of this year’s Dezeen Awards alongside a girls’ school in India made from local sandstone and Waugh Thistleton Architects’ mass-timber Black & White office building in London.

Warehouse robots that work with people

Spotted: By 2026, it is expected that the UK logistics sector will face a shortage of 400,000 workers. One solution to this problem is automation, and our 2022 European Logistics Occupier Survey found that 80 per cent of occupiers believe that warehouse robotics are the top technology disruptor to logistics supply chains. But does this mean that robots will replace human workers? Or will organisations opt for a hybrid approach to automation? 

One startup that is firmly promoting the hybrid route is Robust.AI, a US-based company that develops robots that help human workers be more productive.  

According to the company, many robotic solutions make people feel unsafe and unseen, which leads to inefficient operations. As a result, it has developed a Collaborative Mobile Robot (CMR) called ‘Carter’. This CMR, the startup’s first hardware product, is designed to not only work near workers, but with them. The robots, which are essentially autonomous warehouse carts, move with and respond to human workers – like a ‘dance partner’ – and can be easily taken over manually by a worker grabbing the handlebar. The idea is that the robots will take care of laborious and repetitive tasks, such as transporting objects, leaving human workers to focus on high-value activities such as picking and packing.

Supporting Robust.AI’s hardware is its software suite ‘Grace’. This, the company claims, allows facilities managers to introduce automation quickly without changing their existing environment. To set up Grace, employees walk through the warehouse using the camera on a phone or tablet to map the environment. This creates a digital model of the facility, which can be used to set up workflows, all through a standard web browser. For example, a facilities manager can set up a virtual conveyor belt between two points in a warehouse using the robots. 

The Grace software is also installed on the Carter robots, allowing them to perceive and track people, locations, and objects. The robots then feed their perceptions back to fleet intelligence to optimise the system.

Springwise has spotted many other ways robots are being used, including to clean ships and make deliveries.

LAMA studio turns warehouse into vibrant workspace in barcelona

LAMA studio turns warehouse into vibrant workspace in barcelona

a look inside ‘CODEA PROJECT’ BY LAMA STUDIO

 

Spanish practice LAMA studio has converted a commercial property and warehouse into a vibrant, multipurpose workspace for Codea Studio, a creative agency based in Barcelona. Covering 355 sqm, the space occupies one highly elongated floor and features a 6-meter-wide front façade that originally kept very little natural light from entering the building. The front area is a commercial space with a height of 4.5 meters, varying widths, with flat slabs and metal beams. At the back is a charming open-plan warehouse with a 5.5-meter-high gable roof constructed using wooden trusses, the most characteristic element of the entire space.

 

To meet the agency’s requirements, the architects focused on two interventions. The first was creating a central core to house service areas (storage, technical rooms, meeting rooms, and lavatories), allowing LAMA studio to retain the entrance and rear warehouse as large open spaces. The central core also functions as a transition area between both spaces. The second intervention focused on building a continuous, linear element that runs the full length of the dividing wall from the entrance to the back of the warehouse; this elements takes on different functionalities according to the needs of each area, with various materials and idioms.

 

Specifically, the plan sees the property distributed into four distinct zones. First, the open-plan space adjacent to the street acts as the point of entry to the premises. Next, we come to the central service area which runs down a long hallway. Then, at the back, we come to the unique warehouse area. This will become the main space where the day-to-day running of the agency happens. Finally, in order to open a new back façade and bring light into the building, the old courtyard at the back of the property was restored and three large openings were made to connect it to the interior,’ writes LAMA studio.

mediterranean vernacular meets mexican influences

 

In terms of materials and finishes, the goal was to preserve the original presentation of the different spaces, merely cleaning and painting them in white to create a neutral backdrop against which the renovation stands out. While the office backdrop was kept simple, Codea Studio opted for raw materials and contrasting textures and colors, resulting in a design that reflects a Mediterranean vernacular style coupled with textures and hues of Mexican influence. ‘Rough-finished concrete block with pink tones was chosen to create the main core area and the continuous linear element. This brings personality and robustness to the project while acting as a self-supporting element for constructing the entire perimeter and dividing walls of the core area,’ note the architects.

 

The different extensions appearing in the linear element were built on-site and given a rather rough plaster finish, painted in white, highlighting their handcrafted character. Furthermore, LAMA studio adorned the lavatories, planters, work areas, and other spaces needing special attention with complementary cladding materials like traditional Catalan rasilla bricks and red and green glazed ceramic from La Bisbal. Finally, raw MDF board was incorporated into the renovated warehouse as a more contemporary material with a strong visual accent. ‘It offers smooth surfaces to work with, bringing practicality, as well as elegance, to the project,’ continues the practice.

a multipurpose and light-filled workspace 

 

The entry area is a foyer and multipurpose room characterized by its spare nature, as it has to be adaptable for many uses. At the back, the start of the service core emerges, built using concrete blocks, tiling, and MDF. On the left, a bench appears as a continuous element that runs through the courtyard and changes functions according to each area. The central core, delimited by the high concrete block walls that establish a strong, solid volumetry, hosts two large passageways that function as a sort of antechamber.

 

The first passage leads to the lavatories, and the second to the storage areas and meeting rooms. In these semi-open foyers, the doors are paneled from floor to ceiling in raw MDF to create maximum contrast with the roughness and color of the blocks. The meeting rooms open onto the main hall through large glass doors, extending the reach of natural light while fostering a visual relationship between the spaces. In the main hall, the varying uses required for the workspace are expressed in the continuous element as it runs along the entire side wall with cupboards, work surfaces, a planter, a bench, and finally, to the kitchen and the patio worktop. Here, too, cement blocks, elements of masonry, and other materials alternate according to the function of each section.

 

The kitchen, located at the back of the former warehouse, consists of different modules, either open or closed, with MDF. The extended cooking area, clad in ceramic tile, extends towards the outdoor courtyard. In the center is a large island with a porcelain worktop holding a work and storage area on one side and a bar with stools on the other. Only minimal treatment was given to the outdoor courtyard. It was cleaned and painted in the same way as the rest of the original architectural elements of the project. Still, the team coated the surfaces using a terracotta-colored paint, contrasting with the interior’s white backdrop.

Opposite the kitchen is the dining area, where an imposing metal table by Cristian Herrera Dalmau with an MDF top is rooted to the floor. Dalmau also designed a suspended metal zig-zag lamp hung atop the table, boasting a unique iridescent bichromate finish, as well as the Grillo chairs and Poni stools from Branu. In the central area of the hall, tiered levels and a tall planter clad in rasilla bricks separate the work zone from the kitchen and dining areas. In addition to the plants acting as a lattice between the spaces, this element functions as a relaxation area and a platform for presentations and other agency activities.

 

Last but not least, the work area sits in front of large windows fronting the meeting rooms, with two lines of white lacquered metal tables topped with MDF. The suspended lamps, with the same zinc finish as the one in the dining room, were also devised by Cristian Herrera Dalmau.

Tokyo warehouse revamped into Koffee Mameya Kakeru cafe

Tokyo-based Fourteen Stones Design has designed the Koffee Mameya Kakeru cafe for barista Eiichi Kunitomo in a former water transportation hub in Kiyosumi Shirakawa.

Set in the Kiyosumi Shirakawa area of Tokyo, the coffee shop occupies a warehouse which Fourteen Stones Design renovated and extended “to preserve the appearance of the old warehouse as much as possible”.

The studio removed the shutters from the front of the warehouse, adding a glass facade. The rest of the building, including the interiors, remains as it was – with minimal repairs made to the walls.

It aimed “to make everyday coffee an extraordinary experience” with a full “course of coffee” served by baristas and the renovation has been designed to facilitate this.

A staggered rectangular frame of white oak at the entrance of the cafe, which echoes the coffee package design, dominates the interior space and provides a central visual motif for the scheme.

This frame divides the entrance space from the main cafe where a U-shaped bar surrounding the barista workstations was placed.

The barista’s workbenches, which were made from black granite, were deliberately placed at the centre of the space to create “a stage set-up, which enables baristas to fully demonstrate their skills”.

Besides the new seating area, restrooms, a kitchen, a laboratory and office space have all been renovated.

Baristas work at black granite counters

The service and bar countertops were made from “Jura Yellow” limestone. Featuring fossils from the Jura period, it was chosen for its texture and also for allusions to the passage of time – not only echoed in the coffee growing, roasting and brewing processes but also the journey of the brand from its inception 10 years ago.

Fourteen Stones Design’s Yosuke Hayashi designed the custom furniture for the cafe in the same white oak as the frame structure. It was manufactured by Japanese company E&Y for the project.

The cafe’s owner Kunitomo believes baristas “act as a bridge between the customer and the roastery” and should be given “a social status comparable to that of a sommelier”.

Baristas at Koffee Mameya Kakeru will serve single cups of coffee through to full courses of coffee, “elevated by the newly designed space to the realm of gastronomy”, according to the practice.

Fourteen Stones Design has been shortlisted in the restaurant and bar interior category of this year’s Dezeen Awards. Other projects in the running include a rattan restaurant in Bangkok by Enter Projects Asia Co. and YODEZEEN’s Japanese restaurant in Kyiv’s city centre.
