Welcome to the TRIADA project on Kirlenstrasse in Altstätten.

Here, three modern single-family houses (A, B, and C) are being built, which offer both privacy and closeness as a small community. Ideal for families with children who want affordable living space without having to compromise on generous areas and comfort – even with their own swimming pool if desired.

Protected from traffic and noise, one lives here quietly yet centrally. A common area harmoniously connects the three houses and creates space for encounters, play, and togetherness.

Architecture & Room Concept
The houses impress with clear architecture, thoughtful design, and optimal use of space and area. The arrangement is carefully chosen: it integrates into the protected local landscape while ensuring light-flooded, sunny outdoor spaces.

On the ground floor, there are the entrance, living and dining area, an office, and a guest toilet. Additionally, a reduit directly next to the kitchen, a storage room behind the wardrobe, a cleaning room, and a storage space under the stairs provide plenty of room for everyday life. The spacious carport is connected to a bike and technical room. In House C, the technical room is located within the building itself. A separate shed with carport, bike room, and additional storage space has been created for this purpose.

On the upper floor, there are the main bedrooms, a spacious laundry room, a large bathroom, and an open play area with a loft space between the ground and upper floors.

Materialization & Equipment
The facades combine modern plaster with warm wooden elements, giving the houses an elegant, timeless appearance. High-quality materials in the interior create a bright, friendly atmosphere. The buildings are heated by a sustainable heat pump, complemented by energy-efficient construction that ensures low operating costs in the long term.

Open Space & Outdoor Areas
The outdoor areas of the individual houses range from 155 to 190 m² and offer space for a swimming pool (optionally included in the purchase price) or individual garden design. A covered seating area of around 15 m² invites you to linger outdoors. The plot sizes range from approx. 400 to 520 m².

Project Status & Participation
In close cooperation with the local landscape commission and the building administration, the building application will be resubmitted in the autumn. The start of construction is planned for 2026. Interested buyers can already contact us now to secure a house early. There is also the possibility to participate in the final design and shape the interior according to their own ideas.

Pricing
Prices depend on expansion wishes and budget. The base purchase price (excluding swimming pool) is around CHF 1.4 million.

We look forward to your contact.
