  3. Project Description • For Project 2.3.1, we were required to build an affordable house that met the guidelines set out by Habitat for Humanity. • This involved a maximum square footage constraint to ensure the house would be affordable. The maximum size constraint adjusted depending on the number of bedrooms included in the house. Minimum hallway sizes and a ramp were also required to make sure the house would be wheelchair accessible. • The house also had to meet a minimum size requirement as well.

  4. Project planning These are the design and bubble sketches used to come up with the original plan for the house. The design sketches have a scale where one block = 5 feet, which was used to make sure the house was under the maximum square footage, which it was at 1225 square feet.

  6. Habitat for Humanity guidelines • According to the guidelines, the house had to be under 1233 square feet as it had 3 bedrooms. In order to meet this requirement, I had to remove several rooms from the original floor plan. • The guidelines also required the inclusion of wheelchair accessibility which I achieved by adding a 48 foot ramp at a 12 degree slope from the house to the sidewalk and making sure all hallways were at least 5 feet wide. • Also according to the guidelines, I added a crawlspace under the house that can be used for storage. • All bedrooms in the house were made emergency accessible through a window and a door in the event of a fire, per the requirements. A utility room was added onto the garage for additional storage as well as placement of the water heater. An open kitchen was also required in the design.

  8. Building Code requirements • All plumbing fixtures are connected to the public water and sewage system already surrounding the lot. • Portable water is supplied to the places of living within the house. • House has an approved water heater that works automatically to not waste water or energy. • The pipes of the house are below the frost line. • Sewer drainage pipe is at a 2% slope.

  9. Site plan The site plan set to a scale of 1’’ = 30’ shows the utility lines around the lot, the lot itself, and the house.

  10. Dimensioned floor plan This dimensioned floor plan shows the size of the rooms and exterior features of the house for construction.

  11. Floor Plans Above is the house shown with furniture in the various rooms and the trees on the lot. On the right are the rooms shown with furniture removed and the various rooms labeled.

  12. Door and window sections Image showing doors and windows on the front side of the house.

  13. Wall section views • Wall layers: • Brick • 1’’ Air Gap • ½’’ Plywood Sheathing • 2’’x6’’ Stud • ½’’ Gypsum Board The section view shows the parts that make up the exterior walls of my house as well as the heights of the various levels.

  15. Waste Water calculations • Sewer slope = ( inv. of lateral – crown + 1/2OD )/distance to main • Distance to main = 62 ft • Elevation = 769 ft – 2 ft (frost line) = 767 ft Sewer Slope = ( 767 - 763.15 – .583 )/ 62 Sewer Slope = (0.3161612903225806)/62 Sewer Slope = 0.0526935483870968 * 100 Sewer Slope = ~5.269 Final Sewer Slope = 5%
