Modernization of Existing Properties

Sustainably transform existing properties. Secure long-term value.

The limited availability of building land, increasing energy efficiency requirements and the responsible use of resources make the revitalization of existing buildings more important than ever. Well-designed refurbishment concepts reduce operating costs while enhancing the long-term value, efficiency and attractiveness of existing properties.

The Hohental Principle

Everything from a single source – no interfaces – guaranteed!

As a general contractor, we deliver tailor-made revitalization solutions for residential, educational and office buildings – for investors, property owners and public-sector clients. Smart processes, focused planning, cost-efficient construction, as well as funding and tenant management – all the way through to turnkey delivery at a fixed price. That is the Hohental Principle.

Hohental creates added value.
