Villa and bathhouse in Ticino. Reconstruction and new construction.
Holiday home in Ticino, conversion and new construction on an elevated hillside above Lake Maggiore. Architecture and landscape are set in an exciting contrast and can be experienced. Precise alignment of the rooms accentuates the gaze into nature. Terraces at different altitudes and orientations make it possible to experience nature and vegetation impressively. An intimate pavilion as a guest and wellness house was added to the main building. A concentrated atmosphere in the rooms appeals to all the senses in the wellness area.

Dismantling and new construction, Thalwil. Won competition.
Won Competition of the municipality of Thalwil. Dismantling and new construction of the Blumenhof property, Thalwil. Fee submission for general planner. Our winning project: The replacement building in the historic Blumenhof of the municipality of Thalwil requires a volumetric reformulation of the structure, both in terms of height and footprint, based on the historical building. The striking urban corner situation on Alte Landstrasse is preserved and thus its portal effect. The volume of the new building is sensitively and moderately integrated into the existing building, thus forming a balanced triad with the two historic houses «Villa Sonnegg» and the town hall, with which it is connected underground to the existing garage. The parking garage can now also be accessed more attractively via the access to the replacement Blumenhof building. The facade of the replacement building is designed as a perforated facade with standing windows as a reference to the historic existing building. The existing open space is preserved and underlines the historical ensemble as a «new» small community square as a connecting element. It is intended to invite the public and provide orientation about the community buildings and functions.
The decision of the project commission is: The project commission has awarded the fee offer and the project idea of the company hwa Architects AG, Zurich. The concept is mature, has implemented the requirements of the task very well and still promises optimization potential. The victorious team is congratulated and many thanks for the work they have done.

Hotel Giardino Mountains. Modification.
The architecture and interior design for hotels, restaurants and or other common areas require a different dimensioned planning. Here, the former Chesa Guardalej in St. Moritz-Champfèr was converted into the 5-star resort Giardino Mountain by a complete renovation. Now more space, generosity and casual luxury welcome the guest. The design of the entrance area is a particular challenge, because the guest should be able to see all of the options on offer. He wants to be led, not confused. He also expects a neat, inviting private sphere in the guest rooms and suites. Clear design and fine natural materials ensure relaxed wellbeing. The interior, for which bofor design GmbH and the planning office Bachhuber-Geissinger are responsible, underlines the luxurious overall concept. The three restaurants, which invite the guest to enjoy, also radiate the modern alpine lifestyle character. The spacious and elegant wellness area with its eight treatment rooms and indoor pool also creates with the harmonious lighting design the ideal atmosphere for relaxing and being pampered.

Multi-family houses.Execution plan.
The Reckholderen project in Oberglatt is located on the outskirts of the municipality in the immediate vicinity of the airport. The first thing to do here is to meet the high requirements for sound insulation, and a typical local design should also be implemented. With a single 117 m long facade made of wooden slats and their openings for windows and passageways, the development forms a striking finish on the outskirts of Oberglatt. Two of the four multi-family houses surround an inner courtyard, creating a calm retreat for the residents of the settlement.

Post office Zurich Molkenstrasse. Conversion.
The former post office building on Molkenstrasse Zurich was completely renovated and converted from an office use on the upper floors to residential use. The transformation of an office building into a residential building in the immediate vicinity of Helvetiaplatz and Langstrasse represents an exciting intervention in the existing building structure.
New retail stores move into the ground floor, but office use remains on the 1st and 2nd floors, internally connected via two floors.
The majority of the building was reduced to the shell and the previous office space on the three upper floors was transferred to small apartments and a few 3.5 room apartments.
In the southwest, the new apartments will have a balcony, and the roof areas will be activated as terraces for the general public.

Laboratory expansion at ScopeM, ETH Zurich. Modification.
A new electron microscope with laboratory rooms was installed in the ScopeM at ETH Zurich. The task was to integrate the highly complex technology and all of its pipe and energy connections and safety features in the existing space. For the electron microscope itself, a space secured with Mu metal sheets had to be constructed. Mu-metal is a nickel-iron alloy and offers highly effective shielding from low-frequency magnetic interference fields, which is important for working with modern electron microscopes in order to achieve perfect results.

Reconstruction and renovation of a historic house from 1910 in Heidelberg.
The more than 100 year old apartment building is located in the attractive district of Heidelberg directly on the Neckar and is a listed building.
For decades the house was in a deep slumber, and a considerable need for renovation and maintenance had built up. With the total renovation, this turn-of-the-century house is breathed new life into it and made fit for the next generation.
Through careful coordination with the responsible authorities, especially with the preservation of monuments, a concept of preservation and renewal could be established and implemented. The old was preserved, refurbished and brought back to life and provided with the latest technology. So all water and heating pipes and all electrical lines were removed, relocated and brought up to the state of today's building technology, including the connections of modern IT cabling. All existing parquet floors were sanded and preserved. The simple stucco work as well as the wood paneling as well as the beautiful original entrance doors to the apartments were refurbished and renovated. The old windows were carefully refurbished and provided with energetic double glazing. New windows were built historically. The facade received a careful renovation, whereby the natural stone was exposed again and carefully worked up. The old roof structure could be restored, the roof was completely renewed and expanded in terms of energy.
New bathrooms of today's high standard were installed, as well as new modern kitchens, whereby the original floor coverings made of concrete tiles were preserved or rebuilt.
The original 100-year-old staircase has been completely renovated and returned to its original state.
This resulted in three high-quality apartments with two balconies each with an average of 120 square meters of living space, as well as an attic apartment, which are now ready for occupancy, and which have a unique old building charm with the latest technology.

Relaunch of unique experiences: The Hotel FIVE Zurich.Local architect.
Reconstruction and revival of the former hotel legend "Atlantis" from the seventies, which has been a listed building since 2013 as a post-war modernist.
The prestigious hotel, also known as the former meeting place for celebrities, will open in summer 2022 after a nine-month renovation phase under the name FIVE Zurich, with local Swiss artists involved in several projects in the design of the interior.
The original facade of the ypsilon-shaped building is retained and, with its negative print, is intended to reflect the concrete character of post-war modernism, but now with the integration of the latest heating technology.
The entrance is framed by a 14 meter high alphorn sculpture by the artist Franz Koster. The heart of the transparent atrium will again be the staircase, which will be extended by three floors and creates a special ambience through a light-flooded roof dome. A 43m2 portrait composition by Zurich street artist REDL in the entrance area is reminiscent of the former famous guests of Atlantis and thus gives FIVE Zurich an artistic entrance as a new lifestyle destination.
All public areas such as reception, lounges, bars, clubs and restaurants have been redesigned with predominant materials such as natural stone, wood and marble, paired with Swiss charm. Even furniture from the 1970s is extensively renovated and reused for this purpose, and the fireplace bar in the lounge area, which has already seen a lot, is again positioned centrally there. The 95 hotel rooms have to be slightly enlarged in order to meet today's requirements of a five-star hotel and will all be equipped with underfloor heating.
The new FIVE Zurich combines art, gastronomy and ambient music under one roof as a destination for all new guests, whether from the city or from all over the world.

New headquarter for a cosmetics company in Zurich with a modern, defined concept of the «world of work».Tenant fit-out.
After a comprehensive search process, the cosmetics group managed to find a location for the new headquarter in Zurich in the immediate vicinity of Lake Zurich. The company rents around 2/3 of the approximately 7,500 square meter5 property and will set up around 340 workplaces there. The renovation of the basic extension is carried out by the building owner himself. The tenant fit-out will be built independently according to the plans of HWA Architects.
A future-proof and comprehensive workspace concept with flexible, open areas is to be implemented. Fixed workplaces are to be largely replaced by the principle of desk sharing in order to be able to use office space more economically and flexibly. This requires an expansion of the teamwork and cooperation areas, as well as the offer to promote agile working methods. The three uniform wings of a storey are reserved for more concentrated work. The alternative working environments offered, such as project and creative rooms, open meeting and library areas, break areas, tea kitchens and restaurants can be found in the most prominent,
wing to the west, the so-called «Bellevue Hub», a multifunctional zone with direct access to the terrace. In order to be able to cater to the individual needs of the workplace, the standard workplace is given additional workspace Basic modules supplemented and assigned to focused work in the future. The resulting increasing need for collaboration areas is filled out and increased by well-equipped project rooms, open meeting and informal meeting areas.
The attractiveness of the workplace is to be further increased by supplementary module offers, such as sports and retreat areas as well as areas that allow the employee to feel and experience the identity of the company, such as a boutique on the ground floor and a targeted view of part of the laboratory for cosmetics.
