The Casitas at Canyon Ranch is the first ever fully-serviced development in the Philippines established by Century Properties Group, Inc., one of the country’s leading real estate developer. One of the challenges in developing The Casitas was the terrain of saleable lots. A retaining wall has been required to separate the upper and lower blocks of residential lots. Initial design of a reinforced concrete retaining wall was found to be unsuitable. A green slope finish was also preferred for aesthetics since the area was planned as the exhibit spot in promoting the Canyon Ranch residential complex. Also, cost has been one of the factors that must be considered in the solution.
