And as this projects is located in Soi TonSon which mean ‘the Pine Lane’, the owner therefore named this building “ Pine Crest Residence”. By keeping this name in mind the architect decided to select the wood appearance for the external facade which resembles pine wood and yet create a warmth feeling for the large scale building. To utilize real timber would be too expensive and difficult to maintain and unsuitable for large scale building. So research was undertaken to process the fiber cement planks with acid stain in transforming the color that produces the most similar color and shades of real wood, and yet quite durable to the climate condition. The building utilizes 2 types of materials, acid stain fiber cement plank and washed stone aggregates as surface finishes. As for the washed stone aggregates, it is a very old technique used by Thai builders for many decades. Some may think it is outdated, but actually it can be appropriately applied and suitable to the overall design appearance.
