Our construction projects are supported by selected specialists from start to finish – from planning to financing through to quality assurance.

Summit Development

With the prospect of more

A property is a promise. Clients with challenging construction projects, and investors, place their trust and capital in property. At Summit Development, we deliver that promise. For committed building developers, financial institutions and family offices. Providing a helpful and reassuring service.



Investments & Financing

Progressive project optimisation leads to lower costs and higher returns – quality enhancement included. We improve starting positions, increase returns, reduce costs and sell real estate in the most promising locations in Europe.

Project development & planning

Properties can easily be made to look good on plans and visuals. To prevent disillusionment from setting in, even after several years, an experienced planning team works to ensure that the reality is even better. Architecture, development concepts and usage studies are all included.

Construction management & quality assurance

As general contractors, we manage projects from the drawing board to completion and beyond. Summit Development obtains building permits and constantly monitors building quality, schedules and costs – always in the interests of all stakeholders.


Client benefit: Thanks to our cross-sector network, we can solve problems in ways that others would find impossible. Because we look for the best possible solution to whatever issues and challenges we face in collaboration with our colleagues.
