In the framework of a broad collaboration among German particle physicists - the strategic Helmholtz Alliance "Physics a the TeraScale", an Analysis facility has been set up at DESY.The facility is intended to provide the best possible analysis infrastructure for researches of the ATLAS, CMS, LHCb and ILC experiments and also for theory researchers. In a first part of the contribution, we will present the concept of the NAF and its place in the existing distributed Grid landscape of the experiments. In a second part, the building blocks of the NAF will be detailed with an emphasis on technical implementations of some parts: - Usage of VOMS for separating Grid resources between collaboration-wide and NAF-specific resources - interactive and batch cluster and integration with PROOF - usage of Grid-Proxies to access workgroup servers and AFS - the usage and operation of Lustre for fast data access. A special focus is the seamless integration of the facility into the two geographically separated DESY sites and its implications. In a third part, the experience of running the facility for one year will be reported.
