Yellow Mountain StoneWorks

Our partner and VP of China Operations, Erik Nelson, has just returned from two weeks touring our growing network of suppliers and fabricators in China. During this productive visit, he was able to re-qualify our source for the much sought after reclaimed granite road planks. From the ancient towns of Southern China, we have available thousands of square feet of mashijie originally installed during the Qing and Ming dynasties. The appeal of these materials is the high wear and rich patina that has developed across the Imperial finish specifications: rough chiseled, pineapple and various corduroy patterns. These planks are typically fabricated with the local grey or golden granites. The bottom face of the plank can be sawn off to achieve a 2-3″ uniform thickness and the edges are hand finished to compliment the antique patina, or these can be salvaged as is without any cutting or finishing - cleaned, packed and shipped.

Newly quarried material is available from the same region. This granite can be fabricated in a variety of hand finishes that coordinate exceptionally well with the antique material. Additionally, we have our own Yellow Mountain StoneWorks Antique Finish, inspired by the authentic antique pavers and produced at a lower cost to our customers.

One of the messages we have been getting from several of our clients here in the Northwest, is that there is an increasing shortage of Bluestone, a material used abundantly in landscapes. Rarely can one high grade the ‘true blue’ color, lead times are lagging and prices are rising. In response to this need we believe we have come up with a material or combination of materials that are fine substitutes for this product - our True Blue Slate 0211-SL80, good for random flagstone or cut pavers, veneer or stacked wall stone and our Yangzi River Khaki Blue Sandstone 0214-SA90, which responds beautifully to any cubic fabrication. The slate has an elegant rough hewn finish whereas the sandstone responds well to any one of our 15-20 hand finishes.Pricing is as follows presuming FCL order quantities, current POX pricing and includes delivery to the job site, West Coast MMA:

Material Configuration - Nominal 1″ (254.mm); Nominal 1.5 inch (38.1mm)

A stunning installation of Yellow Mountain StoneWork’s product is in place at the Swedish Executive Screening Center located in the James Tower Life Sciences Building in Seattle. Pepper Brown Granite, Antique Golden Marble and Kinaro Tan Limestone, were combined by Callison Architects to make up the elegant veneer running throughout the hallways of this upscale medical establishment.
The subtle variation in stone characteristics combined with our special finishes creates a rich patina that would otherwise be difficult to capture with a typical honed or polished stone surface. The Antique Golden Marble in particular, has a undulating, tactile surface texture evoking a worn and weathered appearance.

These natural qualities of the stone are a nice departure from the rigid geometries of modern architecture and give this environment a human touch and warmth not always possible in a health care facility. In our experience, this unusual finish application, would not be typically realized on a project with such aggressive scheduling and budget constraints. In this case, our client brought YMSW on early enough in the design process to develop the most elegant, cost effective solution to their customer.
