At the moment, Timber Timber is still just Jephtha Weiss – from summer 2026 onwards, we will be a team of three.
About
Timber Timber AG is a specialized Swiss service company focused on complex timber construction projects. We support architects, clients, general planners and timber contractors throughout all technical and organizational phases of demanding building projects. Our work centers on projects with high requirements in geometry, precision, digital planning depth, fabrication tolerances, logistics, safety and interface coordination.
Founded by Jephtha Weiss and his business partners, Timber Timber brings together more than 60 years of combined experience in delivering national and international landmark projects. Our expertise includes free‑form structures, special constructions, modular systems, large‑scale developments and technically sophisticated timber structures. We serve as the link between complex architecture and successful execution.
We work model‑based, interdisciplinary and solution‑oriented. Our ambition is to translate architectural visions into precise, economical and buildable timber solutions — without compromising design quality.
Timber Timber AG stands for making complexity manageable, for collaborative partnerships and for a sustainable building culture that aligns ecological and economic objectives.
Services
Project Development
We develop robust foundations for demanding timber construction projects, combining conceptual thinking with extensive practical experience from realised buildings. In the early project phases, we create clarity regarding system selection, feasibility, cost efficiency and technical risks. Through variant studies, key details and close collaboration with architects and specialist planners, we ensure that every project begins on a solid, execution‑oriented basis. Our approach blends strategic consulting with a deep understanding of the requirements that arise later in fabrication and construction.
Engineering and Structural Design
We design efficient, fabrication‑ready structural solutions that unite architectural ambition with technical precision. Our work is grounded in decades of experience planning and delivering complex timber projects — from free‑form structures to modular systems and large‑scale developments. We integrate structural engineering, fire protection, acoustics and building physics into a coordinated overall system, optimising material use, construction workflows and installation processes. The result is a structure that performs technically, economically and reliably in practice.
Timber Planning and Digital Modelling
We plan timber projects using fully digital workflows and model complex geometries parametrically with high precision. Our expertise includes parametric modelling — from the form‑finding of complex structures to the creation of detailed fabrication models for CNC production and industrial prefabrication. Drawing on our experience from realised projects, we understand which details work on site and how digital models must be structured to ensure smooth production and assembly. We coordinate all relevant interfaces, account for production and installation tolerances and create a planning basis that is firmly rooted in practical execution.
Project Management
We manage complex planning and construction processes with structure, transparency and a strong focus on buildability. Our services include schedule, cost and quality management, the coordination of all disciplines and the development of well‑considered assembly and logistics concepts. With hands‑on experience from construction sites and project delivery, we understand how processes function and where risks arise. We accompany projects through to completion, ensure technical quality and make certain that planning, fabrication and assembly align seamlessly.
