Primary school, Torricella

The construction of the Torricella-Taverne nursery school is part of the overall reorganization of an area in which the construction of various public, scholastic and sporting works is planned.

The Celoria Architects studio has translated the constraint represented by an existing wall into a resource, which, by touching the individual elements present in the area, defines their mutual relationships. The wall has in fact become the main subject of the intervention, constituting the base of the building and the site of the pedestrian walkway that leads to the school and connects to the sports fields via a ramp.

The three remaining sides of the podium are underground and house the technical and service rooms in a waterproof Drytech Tank structure.

The planimetric organization of the building interprets the functional indications relating to school buildings, with the aim of optimizing circulation spaces, reducing distribution to a minimum and eliminating corridors.

The abstract composition of the volume is however softened by the introduction of some elements somehow extraneous to this composed monumentality, which allude to ancient bastions characterizing their formal expression. Even if the final touch of tenderness is given by the row of small colored scooters parked under the loggia.

AIL tunnel, Agno

The AIL Agno-Bioggio tunnel for high voltage systems runs alongside the Vedeggio river for 4 km and, in a central stretch, is also bordered by the Prati Maggiori canal. Precisely at this point the route of the structure crosses the Riale Roncaccio drainage canal. To overcome it, the tunnel dives further below the riverbed up to -5 meters from the ground level. Due to the particularly delicate position exposed to multiple water pressures, this section of the tunnel was created with a total Drytech Tank: foundation, walls and slab.

The Drytech Tank structure has a thickness between 30 and 40 cm and the joints have been waterproofed with injections of DRYflex expanding resin. By sealing the entire thickness of the joint, the resin also protects the reinforcing bars, because it keeps water completely outside the concrete. In the event of any infiltrations, the system provides practical and easily manageable maintenance from inside the structure, without interruptions to the service.

The real possibility of carrying out maintenance contributes to the main quality of waterproofing: which is to prevent water from entering for the entire life of the work, i.e. for 50 – 100 years in the case of civil engineering structures, as prescribed by SIA 272.

Blade, Canobbio

Rivestimento in Cor-ten della residenza Blade di Canobbio

For architect Mino Caggiula “Designing means reworking what we have absorbed to find new solutions. Blade is the product of the experience lived inside a work of art by the American sculptor Richard Serra.”

The Ticino architect feels it is “a great responsibility to leave a balanced and integrated mark on the territory, capable of generating a harmonious connection with the space and the surrounding landscape.”
The operation was to carefully “scratch” the hilly terrain through the insertion of curved Cor-Ten steel blades, positioned so as to prospectively override the view of the forest to the south and lead the gaze towards the lake.

Organized into two separate blocks, the housing units are divided by a system of primary and secondary blades. The distribution on two levels also generates large terraces, which take on the dimensions of real private hanging gardens.

Tognola Group, which is the promoter and general contractor of the project, also developed the interior design of the villas. The complex also includes a wellness area reserved for residents, with gym, sauna and Turkish bath, plus an outdoor swimming pool.

The entire underground structure, the garage with its lift pit, the SPA and the swimming pool were built with the Drytech Tank system.

Reka Village, Albonago

Infinity pool of the Reka holiday village in Albonago, overlooking the Gulf of Lugano

“Making holidays and free time accessible to all”: it was with this objective that the Swiss Travel Fund (Reka) was founded in 1939, founded by visionary entrepreneurs, trade unions and tourism and transport companies. At the time, travel and holidays were prerogative of an elite.

Reka was created with the aim of making them accessible to an ever-increasing number of families, initially with a targeted savings system, then by developing its own holiday offers at affordable prices.

Reka has expanded and reconfigured the tourist village of Albonago with an investment of 33 million francs, creating 49 apartments, two hotel rooms, a tavern/pizzeria, a panoramic swimming pool, a wellness area, a bicycle station, areas for barbecues and playgrounds, for approximately 270 guests.

Drytech created all the waterproof structures of the car park, underground areas, swimming pools and wellness area.

One of the symbols of the Reka village is undoubtedly the infinity pool overlooking Lake Ceresio, with an incomparable view that embraces the entire Gulf of Lugano, the iconic Mount San Salvatore and extends to the horizon as far as Malcantone. A privilege truly available to all families.

Polis, Pregassona

A double L that welcomes and embraces, enhancing the sense of openness towards the outside. This is the plan of the Polis Multifunctional Center in Pregassona. An architecture that is both symbolic and functional, which guides routes, creates aggregations and integrates the Center into the urban fabric.

The structure was designed by Studio Mario Campi, winner of the international competition in 2008. The subsequent development of the work was managed by the architect Rosario Galgano, until the inauguration in 2021.

The complex is an important resource of the social services network for the elderly in the Lugano area.

On the lower level, the nursery, with its own outdoor play area, overlooks the courtyard, which contributes to the intergenerational and interconnected character of the Polis Centre.

The opposite wing instead houses the structures for the functionality of the centre: radiology, underground car parks, supplier entrance, technical rooms, etc.

This level, partially buried in the profile of the hill, is made with the waterproof Vasca Drytech structure.

Drytech also created the waterproof covering of the courtyard pools, with the continuous Drycoat covering in two colors obtained from the mixture of quartz sands (not from paints) and therefore resistant to continuous exposure to atmospheric agents, without chromatic degradation.

The complex, like every new building in the city, complies with the Minergie energy standard, significantly reducing energy needs. Furthermore, the Polis Center is unique for the self-production of electricity, through an integrated photovoltaic system (BIPV) which exploits both the horizontal surfaces of the roof and those of the facades, equipped with a further 1,600 meters2 of photovoltaic panels.

Aqueduct, Vira-Mezzovico

The new water storage and supply basin is part of the General Plan of the Aqueduct of the Municipality of Vira-Mezzovico.

Set into the mountain slope to minimize its visual impact, the Drytech concrete structure is entirely waterproof, both to the water present in the ground and to that collected in the internal basins. Even the slabs, covered by the lawn, are in Drytech Tank, therefore also resistant to root development.

The perfect correspondence between structure and function of the Drytech Tank makes it not only a solid barrier to water (the waterproofing is as thick as the structure), but also a durable system, because it is predisposed to extraordinarily practical maintenance. To the point that, specifically, any intervention does not require emptying the reservoirs or even interrupting the service.

The modernization plan also affected the water network, renewed for flow and efficiency in all its twenty kilometers of underground pipes.

Drytech Engineering collaborated already in the design phase with Lucchini & Canepa Engineering, for all aspects relating to the waterproofing of the structure.

North face, Pregassona

Rules are (also) made to be broken. The beautiful building designed by Gieffe Studio, for example, has one of the main facades facing north.
An original choice dictated by the shape of the sediment and made possible by the performance of modern thermal insulation systems and materials.

The three-family villa is set in a sloping plot facing north-west, with a 270° view of the Cassarate valley, which ranges from the Denti della Vecchia to Lake Lugano.

Gieffe Studio has therefore designed ultra-panoramic window walls for the living areas, recessed and re-oriented with respect to the front of the building, thus guaranteeing the interiors natural lighting and correct sun protection in all seasons and favoring the view of the mountains on the north façade and of the lake on the west.

At street level there is the garage, connected to the floors by an internal lift, and built with a 700 m2 Drytech Tank. The main entrance is located on the south side, at the height of the third floor.

The rationalist design is made organic by the warm travertine stone cladding and the changing reflection of the mountains and the sky that is projected onto the large windows and the elegant glass railings.
The cut and the different tones of the stones lighten the large continuous wall on the mountain side, harmoniously inserting the volume into the gentle slope of the land.

Town hall, Bioggio

A brutalist structure in red concrete makes the historic seat of the municipality of Bioggio contemporary. Work of the architects Lorenzo Bronner and Luciana Bruno, the intervention added a large external staircase to the eastern façade, incorporated into a thin reinforced concrete frame that recalls the Venetian red of the nineteenth-century building.

A perfect connection between past and present, reiterated and at the same time modernized by the deep frames that define the window spaces. The constant module of the openings on the facades of the original body becomes asymmetrical and intermittent on the new facade, yet recognizable in the grid hinted at by the occasional openings.

The clear stringcourses of the original body connect to the frames of the glass walls that incorporate the new external staircase, establishing a further connection between the stylistic features of the two architectures.

In continuity with the concrete wall, the architects Bronner and Bruno designed a podium in which the large basement garage for police vehicles is located. The podium slab is covered with a large grassy surface that interacts with the brutalist façade.

Two external staircases in the same color as the structure allow access to the entrance level. The footboards of the steps were waterproofed with the Drycoat covering which, thanks to the flexibility of the quartz colour, made the stairs perfectly in tone and integrated with the rest of the intervention.

The Scudo, Stabio

A building that produces environment. It is the new frontier of construction, which extends the concept of sustainability to the regeneration of biodiversity, establishing an active and osmotic connection with the context.

The Scudo di Stabio by architect Giuseppe Rossi is Minergie-P-ECO certified and is the first residential building in Ticino built according to the Swiss Sustainable Construction Standard (SNBS 2.0 BUILDING – GOLD certified). For the innovative choices that characterize it, it was selected among the finalists of the Active House Awards 2022 in the Netherlands.

A sustainability that starts from the volumetric compactness of the structure, functional to the energy efficiency of the building. The construction consists of two systems. The first, in recycled reinforced concrete, concerns the basement, the ground floor and the central distribution volume.

The other consists of the two wooden macro-volumes, dedicated to the apartments distributed over two floors. Vitro-photovoltaic tiles are set on the suggestive cork roof: a renewable energy production system that combines functionality and design and makes the building self-sufficient.

The project also involved the outdoor spaces, planted with native hedges that attract birdlife with berries and acorns.

The vocation for dialogue with the context is also expressed through the promotion of shared and green mobility, thanks to the availability of electric bicycles and car parks with charging stations for cars.

Ra Curta Residences, Montagnola

The project of the Ra Curta residences was born from the conformation of the land on which it stands. The emerging architectural elements follow the natural morphological elements of the lot, so that the project is strongly rooted and in balance with the context. The translation of the blocks downstream and the different heights lie harmoniously on the natural terrain, guaranteeing maximum privacy and visual channels to the lake.

The 4 blocks that are mirrored, accentuating symmetries and proportions, are crossed by two stairways that become urban connections between the streets of Montagnola.

Large terraces emerge from the ground like horizontal blades, the edges of which are made of different materials that form suspended frames and light eaves.
Particular attention was paid to brightness, while still maintaining a high level of privacy.

Drytech created both the hanging swimming pools and the underground waterproof structures, including the long and elegant access corridor to the private garages of the properties.
