The project featured the demolition and then reconstruction of the existing attic floor, resulting in its elevation by another half-story and the addition of a roof deck. 
The apartments in the basement and on the first floor were renovated in order to allow for restructuring of the floor plans, expanding them in some places and changing window openings.

A new parking deck at the second floor level on the northside creates additional parking and storing space, allows for external access to the uppermost apartment, and also serves as roofing to the entrance and parking spaces on the first floor level.

The original three-story house was built in 1978. It had a gabled roof, a semi-subterraneous basement, a first floor and a second floor. In 2020, the family decided to renovate and expand to create space for three apartment units.

The family residence is located above the market town Silandro, on the south-facing slope of the Val Venosta Montesole Mountain. Nestled on the steep and warm dry slopes we find single and multiple family homes with gardens as well as vineyards. On the opposite side of the valley, the Montetramontana mountain with its flush meadows and forests rises to impressive summits. The valley plain spreads graciously from east to west, steadily inclining to the west towards Resia Pass, here and there interrupted by alluvial fans. 

Renovations on the lower floors allowed for the creation of generous and bright rooms offering open private space. The basement apartment features south-facing living areas with a loggia to the garden. On the first floor, renovations produced a living room that opens to a balcony on the southside and to the west has a weatherproof terrace. An outside staircase connects the first floor to the garden. The apartment on the second floor is accessed via the parking deck on the northside. An inside staircase allows for access to the downstairs floors.

An unpolished standalone marble slate from the nearby Weißwasser Quarry in Lasa separates the entrance and living areas. Behind it, the second floor spreads out along a generous window facing south. On the westside, there is a sheltered terrace. Besides a spacious living room with kitchen, there are two bedrooms, two bathrooms and a studio. The open floor attic space and the roof terrace are accessed via stairs on the inside.

The plastered building foundation holds the rehabilitated floors, while the vertical expansion is veiled in a curtain-wall facing with air space made from larchwood boards and folded raw aluminum elements.

Different generations occupy the house now. Thanks to the layout of open spaces, development and arrangement of facades, residents are guaranteed plenty of privacy. To the south on all floors, the facade features generous windows opening towards the Montetramontana mountain and the valley plain. Recesses create sheltered  outdoor areas. Each floor has different assets to boast, ranging from spectacular views, terraces, gardens and loggias.
