Our experience guarantees construction work of the highest quality.
We specialize in adapting to the changing needs of the market. That is why we erect buildings as general contractors or shell contractors. We do structural alteration works and redevelopments. In all cases, we guarantee the highest quality of our work.
We approach each project with the same commitment. For a simple reason – it ensures ultimate success. Therefore, GWI Bauunternehmung GmbH has been shaping architecture in North Rhine-Westphalia for almost 30 years. Now, as part of MOD21 GmbH, we are transferring our approach to the whole of Germany.
