This project comprises a 90 degree bay window and a bow window in addition to a large number of single windows and doors. The construction drawing layouts for the contractor were agreed with the architect and confirmed on site with the contractor by Marvin Architectural installation personnel to ensure that optimal standard sizes were used to reduce the cost as well as enabling the installation to proceed smoothly. The drawing includes dimensions for block layout and positions for steel structural support positions. All elements were carried out by in-house personnel in Marvin Architectural.
