Similar to the modeled square foot method used for commercial buildings To account for the quality of the proposed houses, cost data is divided into four classes: economy, custom, average, and luxury. The size of the house is taken into consideration by accounting for the number of proposed floors in addition to the square footage: one-story, one-and-a-half-story, two-story, two-and-a-half- story, three-story, bi-level, and tri-level. Other configurations considered include: detached house, semi-detached house, or townhouse. The costs listed in R.S. Means for residential buildings are based on basic configuration (e.g. roofing, number of bathrooms, basements ...etc.) and the estimator needs to adjust the cost based on how the requirements of the proposed house differ from the basic configuration. Please provide a Conceptual Cost Estimate Develop different possible design/quality scenarios for a Single Family House comparable to the Johnson's Residence. Your scenarios should be based on the information and the level of scope definition expected during the conceptual phase of the project
