2000 L Street NW | Alexander Court

Alexander Court was a very ambitious project designed to merge two existing office buildings into one larger office building. This project is now the largest office building lobby in Washington, DC market.

This trophy building was designed by the world-renowned Architect Pelli Clarke Pelli. Alexander Court offers frontage along four major thoroughfares, including an entrance on K Street, and an expansive lobby fronting L and 20th Street featuring an iconic twelve-story atrium. The design is unique because of the creative design of the project architect, Ms. Magdalena Kowalska, and her desire to use only the finest Statuario Venato and extra marble for the vast amounts of lobby wall stone.

The walls are a reproduction of the vein pattern of the quarry wall face; this continuous vein pattern match was created by the fabricator Euromarble SRL using their innovative virtual dry set software. This software allows the designer to see in true shop drawing elevations the actual slabs selected for each block and each wall. This is a very detailed process that yielded unprecedented results for the finished marble appearance. The design also includes angular LED lighting, which is hidden in the out of plane wall designed to cast light both upward and downwards to create an exquisite modern approach to public space lighting, as well as to feature the elegant wall marble. This continuous vein matching was used on over 15,000 sqft of wall surface with walls as long as 180’.

The public lobby flooring is more minimalist and relies on a very hard and durable basalt called Basaltite quarried in the Italian region of Lazio. This elegant dark grey / black flooring accented with inlaid stainless-steel accent pavers provides a genuinely subtle and robust foundation for the fantastic wall marble features. The lobby desks also exhibit a very complex geometry and design; these desks are all clad in stone as well. Winner 2018 Natural Stone Institute Pinnacle Award
