TALVO PERINI MADULAIN

Expansion 2012 – 2014
Residential building
Private

 

Connected to Chesa Perini, the Talvo could be accessed directly from Chesa Perini through two simple doors. A classic passage through the living area's central hall was not possible due to its hillside location.

Even after dismantling, the Talvo remains as one unit.

Thanks to the farmers who followed the proposal to leave areas undeveloped throughout the Talvo heights, the character of the Talvo remains palpable and visible.
The spatial programs are distributed over 2-3 levels. Like Chesa Perini, the Talvo is also connected to the municipal district heating supply of Madulain.

Remodeling 2009 – 2014
Apartment building
Private

 

In a central location, in the old village center of Madulain, stands the protectable object Chesa Perini. The structure and layout of the residential units have been preserved.

In respectful consideration of the building's fabric, the four residential units were adapted and expanded to meet today's living needs. The heating system is connected to the district heating plant of the municipality of Madulein, which WOD energy from pellet combustion.

STALLA CAPELL SILS FEX

Renovation 2014 – 2015
Residential building
Private

 

The former stable was converted into a residential building in 1974. The fragmented floor plan layout and the sparse lighting were decisive for the decision to completely strip the stable shell from its interior.

The different uses are organized on the two new, open levels. Only the wet areas were provided as separate areas.
Generous glazing behind the original wooden facade provides ample natural light without altering the exterior appearance.

CITY HAUS ST. MORITZ

Renovations, extensions, and conversions 1980 – 2014
Residential and commercial building
Private

 

Prominently located in the heart of the pedestrian zone in St. Moritz Dorf, the City Haus presents itself as an urban building. For over a decade, we have had the privilege of accompanying the building through renovation work on the facade, the entrance, and the stairwell, as well as through conversions and extensions of office spaces on various floors.

Unlike the straightforward lines of the facade, the office spaces cater to the individual needs of each tenant. The new element, recognizable as an intervention, is intended to integrate seamlessly into the existing structure.

Expansion 2006 – 2007

The two former stables are part of Alp Blaunca, which lies above Lake Sils at an altitude of 2040 m above sea level.

From the outside, the renovation is barely noticeable; only the flower decorations suggest that work has been done.

During the entire summer season, both buildings are permanently inhabited, so all space requirements had to be taken into account. In winter, Blaunca is only accessible on foot.

CORVIGLIA MOUNTAIN STATION ST. MORITZ

Renovation and Expansion 1993 – 1995
Mountain station with restaurants
Municipality of St. Moritz

 

With the yellow surround of the cantilevered lower restaurant «Marmite,» the Corviglia St. Moritz mountain station is an eye-catcher.

During the short summer season, the extensive renovations and expansions were carried out. In addition to the self-service and a full-service restaurant, sanitary facilities, staff and storage rooms, and garages were designed.

All processes had to be coordinated with the existing mountain station of the funicular. The openings allow generous views of the surrounding mountain world and define both the facade and the interior of the restaurant.

CORVIGLIA CLUB ST. MORITZ

Expansion 2006-2007
Club local
Private

 

The traditional Corviglia Club is located next to the Corviglia mountain station in St. Moritz at an altitude of 2486 m a.s.l. To offer members more space, an extension of the restaurant was carried out in the basement. The rectangular volume integrates into the sloping surroundings and can be seen as a plinth for the existing building. The extension serves to enlarge the existing terrace on the upper floor.

The hillside location lends itself to the creation of generous openings. The panoramic windows then define the interior. With the exception of the fireplace wall, the room paneling and furnishings are entirely made of Swiss stone pine.

HOTEL WALDHAUS AM SEE ST. MORITZ

Extensions and renovations since 1985
Hotel and Restaurant
Private

 

 

Since 1985, we have had the pleasure of assisting with various projects at the hotel. The prominent location of the Waldhaus am See demands targeted and well-considered interventions that meet the needs of both internal operations and external perception. In 1994, the major expansion of the ground floor area towards the dairy took place, adding rooms and apartments, and the underground parking garage was constructed beneath the parking level.

Individual areas such as the kitchen, the spa, the reception with its adjacent rooms, and the whisky bar with its storage – to name just a few – were continuously adapted to evolving requirements. In 2013, within 6 weeks, 2/3 of all wet cells were renovated and the sanitary pipes were generally renewed; individual rooms were completely remodeled, while others were refreshed.

CHESA ANTICA CELERINA

Core renovation with remodeling 1986
Residential building
Private

 

The listed building is located in the old village of Celerina Crasta and dates back to 1648. The room layout is typical of a classic Engadine house, with a Stüva (living room), Chadafö (kitchen), and Spensa (pantry), accessible via the Suler (passage to the hay barn). The bedrooms are on the upper floors.

Access to the room above the Stüva is still available via the Burel, the staircase behind the stove.

As part of the modernization, additional bathrooms were installed, and the stables in the basement were converted into utility rooms. The cellar still has an earthen floor. Unfortunately, during a change of ownership, the former hay barn was converted and is now accessed and used independently.

Today, as then, the living space is organized as a single residential unit.
