At SPG, we transform your ambitions into shining achievements. Whether new construction, renovations, vertical expansion projects or asset repositioning, we guide and support you through each phase of your project, from feasibility studies, financial analyses and applications for permits to contractor selection and worksite management. The possibilities are endless!


Breathe life into your projects whilst calling all the shots
Imagine a building. You can picture it in your head, but there are numerous obstacles between intention and construction, for example, aligning creativity and feasibility, working within current regulations and coordinating the services of experts. At SPG, we face these challenges with you so your project can materialise.
Interdisciplinary expertise, every step of the way
Our Real Estate Development Department will guide and support you, from the preliminary sketches to handover of the keys. We manage every phase rigorously, meeting the utmost standards and paying meticulous attention to detail, to breathe life into real estate projects that are coherent, sustainable and true to your vision.

A joint venture in keeping with your ambitions
From residential properties, offices and industrial space for lease to convenience stores, individual dwellings and commonholds/condominiums, our expertise covers all types of construction and major renovations.
This diversity is also evident in the different types of clients we work with: institutional investors, family offices, NGOs, real estate foundations, housing cooperatives, public entities and even cantons.
Every project comes with its own language, demands and vision. And every project owner receives our full attention and commitment.

Do you have a project? Our team is here to support you.
