Renaissance architecture, as the mainstream architectural style in Europe from the 15th to the 19th century, shines with the brilliance of human wisdom and art. This style sometimes incorporates the characteristics of Baroque and Classical architecture, but its roots are deeply rooted in Florence, Italy. The design of cast stone window surrounds is an indispensable part of Renaissance architecture, adding endless charm to the building with its unique design and exquisite craftsmanship.   Under the theoretical guidance of Renaissance architecture, the design of stone window surrounds abandoned the Gothic architectural style that symbolized divine supremacy, and instead pursued the architectural forms of ancient Rome, especially elements such as classical column proportions, semi-circular arches, and architectural forms centered on domes. These elements are perfectly reflected in the design of stone window surrounds, making every detail full of classical charm and historical significance.   The design of stone window surrounds not only emphasizes the external beauty of form, but also emphasizes the internal structural beauty. Designers cleverly use the natural texture and color of stone to perfectly integrate window surrounds with the overall building, making the building visually more harmonious and unified. At the same time, the firmness and durability of the stone also ensure the service life of the window surrounds, allowing the building to maintain its unique charm in the baptism of time.   Under the influence of Renaissance architectural style, stone window surrounds design has become a unique art form. It is not only a part of architecture, but also the pursuit and expression of classical aesthetics and humanistic spirit by architects. Whether it's luxurious palaces, solemn churches, or cozy residential buildings, stone window surrounds add a unique charm and charm to the architecture, allowing people to feel the cultural atmosphere and artistic charm of the Renaissance period.

03. Facade strategy: the high-end feel of low-priced stone   How to have a unique temperament for an international five-star hotel is a challenge for designers. Although the cost is low, through careful design, it can still meet the requirements of low-key luxury. In the entire project, the small pillars of the triangle are the most important language. In addition to "turning the surface into line" to handle the color difference of cheap stone, what is more important is the small pillars of the triangle, giving the entire building a sense of delicacy and unique temperament. The triangular surface adds a sense of hierarchy to the facade and is rich in shadow relationships in the sunlight.   In addition to the three edges of the standard unit, the window frame is also treated as two edges, and the entire building has a unified vocabulary and consistent approach, making construction control relatively easy (it is difficult to find large curtain wall construction companies for low-cost curtain walls). The slender and powerful stone at the window frame is the greatest reflection of the delicacy of this project. The slender two sided stone window frame and the three sided slender columns form a unified and varied rhythm.   Fine stone pieces, if assembled at a conventional 45 degree angle, will have many notches and expose the interface directly to the outside. In node design, two pieces of stone are spliced using a 90 degree half bite joint, utilizing the hardness of the granite itself to form a small groove, rather than blindly pursuing difficult to achieve "sharpness".

01. Selection of Stone   Firstly, the designer and the client agreed on the goal of retaining the stone curtain wall and changing the original open curtain wall method to use glue at a cost of 125 USD$. However, other areas cannot save much money and can only consider the stone itself. In the end, for 17 USD$ per square meter, only the red and greatly different colored G681 red granite can be selected. The pink color of this stone does not meet the requirements of this project, but making a lychee finish can approach gray granite and effectively reduce color difference.   02. Facade strategy: low price stone processing method   When facing stones with large color differences and poor texture, the design should be tailored. Firstly, try to avoid using large stone surfaces and use "lines" in the design. This not only conforms to the characteristics of hotel standard windows, but also expresses the material of the stone while avoiding color differences. It avoids the weakness of low-priced stone through a sense of lines. Secondly, in areas where large surface stones are unavoidable, "grooves" and "lines" are used to treat them, and different surface treated stones are used to form a sense of hierarchy. In the division of stones, techniques such as "staggered joints" and "horizontal and vertical joints, corresponding to different surface stones" are used, and a smooth line is "pointed" every few layers.

As is well known, China has abundant stone resources, and there are many varieties of granite stone, whether it is ordinary black and white gray or colorful yellow green red, all of which can be seen in the stone market. And it is widely used in various engineering sites. In recent years, various self built villas have become popular, and many have chosen domestic yellow and red granite for the exterior walls.   In some high-end hotel and office building projects, with sufficient budgets, expensive imported granite is mostly used for curtain wall stones. Some imported granite varieties from countries such as Brazil and India do have unique and beautiful colors and textures. But can't cheap domestic granite achieve good curtain wall effects? Today we will share the stone curtain wall design of a star rated hotel. What do you think of the effect of using domestically produced G681 red granite?   This is a very successful, low-cost, and high completion project - Chengdu Xiehe Hilton Hotel. At the time of project approval, it was part of the comprehensive development of the entire area. At that time, the overall plan was to provide a residential area of about 400,000 square meters with a five-star hotel, a Grade A office building, and a commercial street.   As an international five-star hotel, the initial cost of the facade was not low. But after the completion of the first phase of development, Party A did not obtain any subsequent land, so this hotel must be cost conscious. The unilateral budget for the exterior wall is only 125 USD$. At this time, either we need to change the exterior wall material or find a solution to the problem.

Regular cleaning: Clean the marble surface regularly with a neutral and mild detergent and avoid using detergents containing acidic or alkaline ingredients. When cleaning, you can wipe it with a wrung-out soft cotton cloth and avoid using a rough cloth or brush.   Avoid prolonged exposure to sunlight: Prolonged exposure to sunlight can cause the marble surface to fade or crack. Therefore, if the marble needs to be exposed to the sun, it is recommended to use sun visors or curtains to block it.   Avoid exposure to chemicals: Marble is susceptible to chemical attack, so avoid exposure to acidic, alkaline or corrosive chemicals. If chemicals need to be used, it is recommended to test them before use to ensure they will not cause damage to the marble.   Regular maintenance: Regular maintenance of marble can extend its service life. For example, polishing the marble surface regularly can maintain its gloss; regularly check the seams and edges of the marble to ensure that they are not loose or damaged; regularly check the supports and fixtures of the marble to ensure that it is firm and reliable.   Avoid dropping heavy objects: Although marble is hard, it can still be damaged by heavy objects. Therefore, avoid placing heavy objects on marble surfaces, especially high places.   In short, the care and maintenance of natural marble is very important to extend its service life and maintain its beauty and gloss. At the same time, you should also pay attention to avoid damage to marble in your daily life, such as avoiding long-term exposure to the sun, avoiding contact with chemicals, and avoiding falling heavy objects, etc.

The color and texture of green natural marble are one of its most unique characteristics. The color of this stone ranges from light green to dark green, and the textures are different.
