Giresun Alucra Stone House 2/6

Gray Bayburt Olive Stone + Ivory Bayburt Tuff Stone

Project story

Realized in the Alucra district of Giresun, this modern stone house project brings two distinct textures of natural stone to the exterior facade with a flawless architectural contrast. The Bayburt Olive stone, applied to the main exterior walls, features a split-face finish. This textured surface creates beautiful shadows under the sunlight, adding a strong and dynamic character to the structure. To balance this rugged natural texture and frame the building with a modern touch, smooth-cut Ivory Bayburt Tuff stone was selected for the window jambs and vertical moldings. The bright and smooth surface of the ivory tuff perfectly highlights the wild texture of the split-face olive stone. This unique stone house unites the enduring strength of nature with clean modern lines on a single facade. Providing breathability and superior natural insulation against Alucra's demanding climate, this project stands as a prime example of innovative stone house aesthetics.

Gray Bayburt Olive Stone + Ivory Bayburt Tuff Stone · Gumushane, Turkiye

Project story

Completed in 2024 within the social living spaces of Gümüşhane, this pergola project brings together the finest examples of nature and local craftsmanship. Two exclusive natural stones originating from Bayburt, Bayburt Ivory Tuff and Bayburt Olive Stone were harmoniously utilized in the structure and its architectural details. While Bayburt Ivory Tuff imparts a luminous and noble character to the structure with its spacious ivory shades, the Bayburt Olive Stone integrated into the accent areas completes the design with organic tonal transitions derived directly from nature. Easily workable upon extraction and hardening over time upon exposure to air, this unique combination of tuff and natural stone provides exceptional climate adaptation and thermal insulation against Gümüşhane's challenging weather conditions. These social facility gazebos have become architectural landmarks for those seeking both aesthetics and enduring durability.

Trabzon Araklı Plateau Stone Villa 5/6

Gray Bayburt Olive Stone + Ivory Bayburt Tuff Stone

Project story

Realized in the unique natural setting of the Araklı Plateau in the Black Sea region, this exclusive villa project brings together two precious natural stones of Bayburt in perfect harmony. Gray Bayburt Olive Stone and Ivory Bayburt Tuff Stone were meticulously blended across the exterior cladding, architectural accents, and the outdoor fireplace area. The bright appearance and natural insulation properties provided by the ivory tuff were perfectly balanced by the noble stance and structural strength of the gray olive stone. The specialized craftsmanship, achieved by arranging cut stones of various dimensions in a horizontal format, created a natural rhythm of color and texture across the large facade surfaces. Furthermore, the rough-cut stonework preferred for the surrounding retaining walls ensured the villa's organic integration into the rugged mountainous geography. Creating a highly durable and aesthetic armor against the harsh climate conditions of the plateau, this project offers a long-lasting, prestigious living space in the heart of nature.

Project story

Rising in the striking landscape of the Trabzon Limon Suyu Plateau, this modern stone villa project reflects the power of natural stone in minimalist architecture. A remarkably clean and spacious appearance is achieved by utilizing smooth Ivory Bayburt Tuff stone across the broad exterior surfaces of the building. To break this expansive monolithic look and add modern dynamism to the facade, Bayburt Olive stone, with its dark and elegant tone, was selected for the horizontal floor moldings and window jambs. The sharp color contrast created by these two distinct stones perfectly highlights the clean architectural lines of the cubic design. Providing superior natural insulation against the challenging climate conditions of the plateau with its breathable structure, this stone villa is an innovative living space that unites nature and modernism in a single mass.
