Final Phase of Construction

Things are looking like our Guesthouse is in it's final stages, and getting ready for some occupants. We have the flooring nearing completion, and some our artisans are completing the roof as I type this.With so many things happening here at Wondergrass it seems like we are at the center of sustainable building movement. Yesterday we had first year architecture students from a new arch university in Nagpur, India visit us and look around at what we are doing. Some students were eagerly impressed, and others looked at us, and said, "My family has been living in bamboo/mud house for 65 years, there is nothing new here. The mix of housing elements that India currently has, gives us the task of introducing the new, but giving it new appeal towards mainstream construction standards. It is a weekely accurance that someone gets in contact with or us or visa versa and we make a new connection for out product to reach more people. We have realized that durability will sell our bamboo homes as much as anything, and cost comes secondary. With bamboo, there is no problem with tension holding, but compression a problem with bamboo natural flexibility is a task we are currently taking on. In the past we have set up some worth while testing on different composite beams. Several years ago we built a ground plus one story structure, and the beam we used was a closed web plywood insert truss. We tested it with at least 900lbs of concrete bags and it held with great strength.Using plywood for insert is structurally stable, however we are not happy with using plywood as it has a high embodied energy, as well as it cost. Over the years we have used different strength truss/beams for different uses. We are now working with bamboo open web trusses that mimic commercial open web trusses sold on the market. If this brings successful results, we will be using these trusses more often. There advantage is that they use less metal fasteners, and also create less time for construction. At wondergrass we always have to balance construction with a bit of artistic design. We have finished one of our mosaic tile patterns, and we are happy with the results. Since this space is going to be out HeadQuarters in Bamboo housing design the intent to make this place as pleasant as possible is necessary. Below is a picture of our roof tiling. We are using traditional tiles made by local craftsman. These "country" tiles are half round mud tiles, that can be made rather quickly, and are very cheap. Vicenta' is currently finishing up the last swath of tiles, and fortunately, if a rain comes, we will be prepared.
