View ProjectCan’t be done? For Schwitzke Project, there’s no such thing. Whatever needs to be done with an existing building, we make it possible. Renowned architects, investors, and major brands trust us. Precisely because their endeavors are especially challenging. Unconventional ideas and designs? From preliminary sketches, we create one-of-a-kind spaces. Multinational projects with the simultaneous deployment of dozens of technical crews? We can handle it. Stay curious, think further, make it possible. This is the attitude that has driven our success. We employ a workforce of roughly 70 today – all ready for the next challenge. Get to know us better.

Optimizing construction processes and radically reducing costs.
Are you about to begin your building project? With lean construction management, we’ll show you specific levers to make operations more efficient and significantly shorten building times. The agile method starts in the planning phase. Working with you in a structured process, we’ll closely examine the full value creation of your project. Our approach: First, we define your building objective – what result do you aim to achieve, and in what quality and what period of time? With the overall project firmly in view, we dedicate ourselves to each individual phase of preparation and construction. Our guiding principle is to avoid waste.
We identify unnecessary activities and provide for the exact daily scheduling of all technical crews for handover points, blocked-off areas, resource allocation, and material flows. Paths on the construction site are shortened and stop-and-go is eliminated. Responsibilities are precisely defined. Processes are made leaner in terms of personnel as well. Tested management tools use transparent key figures to provide for cost monitoring and control within narrow time frames. This enables us to reduce risk.
Schwitzke Project has extensive experience and success in guiding lean-management projects. Ask us what we can do for you.
Focus topic: sustainable construction.
How we make building projects greener.
Do you want to tackle your next construction project more sustainably? Are you seeking certification according to one of the rating tools of the WGBC (World Green Building Council)? Schwitzke Project has been an active member of the German Sustainable Building Council, DGNB, since September 2017. Our employees are trained and certified there and receive further training on an ongoing basis. This enables us to realize projects in fulfillment of the LEED international guidelines and advise you accordingly in advance. This is part of our company policy – as is the regular ecological and social auditing of our suppliers.
Before building, we make sure to use ecologically safe products and low-emission construction materials – ranging from solvent-free paints that meet the RAL-ZU 102 standard to textile floor coverings with the GUT quality seal. This also means that we consider as many materials as possible in a holistic way, over their entire life cycle. When we build, we implement systematic waste management, avoiding refuse where possible, and otherwise reducing, separating, and sustainably disposing of it, as well as transparently documenting its disposal. We’ve set a waste recycling target of at least 75% – and rising.
We see ourselves as a part of your ecological footprint and are constantly striving to enhance our performance in this respect. Since 2023, our vehicle fleet has been completely emission-free. It’s important to set a high bar.
Find out how we can advance your project sustainably.
How we approach cradle-to-cradle projects:
Our expertise extends to creating a sustainable closed-loop system of building materials in the most consistent way possible. Whether for new construction or a building revitalization, a project planned and implemented according to cradle-to-cradle principles calls above all for a systematic approach. This begins with the initial decision and runs through every phase of the project as a common thread. Find out more in the podcast about how we conceive and drive forward cradle-to-cradle projects.
