In the midst of the harmonious landscape between Aarau and Zofingen, the final stage (Tract E) of the Sommerhalde is being built, a residential complex that perfectly combines modern aesthetics, sustainable building culture, and generous spatial structures. For lovers of contemporary architecture and high-quality materials, a living standard is being created here that goes far beyond the ordinary.

The last building block of the exposed concrete masterpiece by the renowned architectural firm "Diethelm + Spillmann" from Zurich.

With the 3rd and final stage of the Sommerhalde, the final "Tract E" is being built, with a total of 7 residential units.

• Construction start: Spring 2026

• Planned move-in date: Autumn/Winter 2027

Modern, progressive, architecturally unique:

The Sommerhalde sets a clear accent: exposed concrete, clear lines, maximum transparency, and a design that puts space, light, and views at the forefront. The elevated, sunny location gives each unit special privacy and impressive long-distance views – a home for people who consciously choose quality and design.

This exceptional duplex apartment convinces with generosity, versatility, and architectural refinement. Two levels with different room heights of up to 2.72 m offer an impressive living experience and enable individual living and working worlds – ideal for demanding couples, home office users, or design-oriented owners.
