General contractor: A fixed contact person

With coneon, you have just one contact for your complete interior design. You don't need to worry about selecting the companies you want to work with. From our extensive network of manufacturers, suppliers and craftsmen, we search out the right companies for you. Due to many years of cooperation, we know about the quality and reliability of our partners. We coordinate the appropriate and professionally qualified craftsmen and service providers to ensure a smooth process and guarantee good quality in all construction work.

On-time delivery

Our expertise in construction scheduling ensures that all work is completed on time and according to plan. To the day, we create a schedule to which our craftsmen, suppliers and fitters adhere. With an agreed fixed date, we ensure that your premises are ready for handover on that day.

Cost planning and construction control

We work cost-consciously - that's why our goal is to deliver the best solutions for your budget. We're always looking for ways to save you money without sacrificing the overall look of your office facility.

Architectural services ensure constant cost control before and during the interior design process. This makes it possible for us to offer you a fixed price. For each project, the project manager keeps a constant eye on cost control before and during the construction phases. From the preparation of the plans to the final handover, all service phases are managed by coneon.

Building regulations

In the construction planning phase, all planned conversions and extensions are thoroughly checked, statically analyzed and approved. Topics such as fire protection and safety engineering are important components of the planning phase.

General contractor vs. general transferee

A general transferee often has his own construction company with which he executes his orders. Our job as a general contractor, on the other hand, is to plan and control the course of a project and execute it with the help of various subcontractors, such as painting contractors or drywall companies. This means that all services are coordinated together and come from a single source, completely stress-free and convenient for you.

No interruptions for you

We build in the existing building stock. coneon ensures that you can continue to work during the conversion. If you wish, we can take over relocation management, interim storage and organize transitional solutions. This means you lose no time and can concentrate on your day-to-day business with peace of mind.
