A thoughtful blend of slate and limestone

April 1, 2010
Natural slate flooring is a defining element of the Riata Gateway in Austin, TX, which was purchased by the Texas Association of School Boards as its headquarters. The material was quarried in England by Burlington Slate, Ltd., and supplied by Burlington Natstone of Plano, TX.


Originally intended as a space for multiple tenants in Austin, TX, the Riata Gateway was ultimately purchased by the Texas Association of School Boards as its headquarters. The project design makes extensive use of natural stone, including limestone for the vertical surfaces and an innovative combination of slate planking with aluminium bands for the flooring.

The architects at Susman Tisdale Gayle (now STG Design) were responsible for the construction and interior finishes of the 148,000-square-foot, three-story space, which includes a large conference center, a child care facility and a cafeteria.

In all, approximately 3,000 square feet of Burlington’s olive green honed Bursting Stone was installed in a random running bond pattern.

Essentially, the facility is comprised of two office buildings with dual main entrances conjoined by a large, two-story communal lobby. For the floors in this area, STG Design specified natural stone flooring from Burlington Slate, Ltd., and supplied by Burlington Natstone of Plano, TX. In all, approximately 3,000 square feet of Burlington’s olive green honed Bursting Stone was installed in a random running bond pattern.

The decision to use Burlington’s natural stone for this part of the building was made, in part, because one of the client representatives had a positive experience using the material in his own custom-designed residence. Additionally, Burlington cited the architect’s long-standing appreciation of the material’s aesthetic and technical properties. 

As a means of further breaking down the enormity of the lobby area, STG Design devised an innovative plan where the Burlington slate was set within 10- x 10-foot “grids,” set apart from one another using thin satin aluminum accent bands, along with wider bands of limestone.

“As designers, we have long admired Burlington’s stone for its intensity, unusual textures, density and simple elegance,” according to STG Design. “We were therefore elated to work with a client who shares our enthusiasm for Burlington’s natural stone palette and product range.”

Furthermore, a repeat of limestone bands was integrated within the flooring scheme, and these appear to “march rhythmically” from the landscaped exterior paths into each side of the lobby. 

For feature walls and the elevator lobby, the architects selected a pattern of rough-cut, textured Texas limestone, a popular material in and around the Austin area.

“The use of the Burlington stone, limestone and aluminum serve to not only complement each other beautifully, they deliver what is both an attractive and functional floor area that befits an office building of this character,” stated STG Design.
