Four Level Graduate Hospital Rowhome

Location: Graduate Hospital, Philadelphia

Building type: 3-story Rowhome built in 1915

This expansive addition began with a growing family and their decision to either move out of their quiet neighborhood or take over some of their generous rear yard. Our client had outgrown the 3 story house but they loved their neighborhood and their kids were already connected to other great families on the block. They felt stuck without a plan.

Exploring Options for Various Home Addition Plans

Our clients recognized that planning and completing an addition to their home would be a big move which is why they had talked about the idea for almost a year before we began working with them. We started by discussing their ideas about how much additional house they really needed and how much that could cost. 

Discussing Budgets and Finding out How Much a 3 story Home Addition Costs

How much would this home addition cost? The answer turned out to be: More than they originally thought when they began their journey, but less than many other contractors had warned. We explored many issues around budgeting for the most important elements of the project. We helped them to arrange their various needs into a prioritized list as follows:

  1. An updated kitchen with an improved working areas and space to spread out and for storage
  2. Improved natural light from whatever means (skylights, windows, glass doors)
  3. New powder room near the kitchen (but not too close)
  4. Breakfast nook for eat-in options and for studying area
  5. Daughter's bedroom with additional closet space
  6. A combination guest room/office space with additional storage
  7. A roof deck, if possible
  8. Renovation of other areas of the house, if possible

Listing these goals helped clarify how we would focus our design time and also created a plan for success. If we start from the top and identify what the expectations were for the finishes, we could quickly build a cost range that would define a budget for their 3 story home addition. The kitchen addition would be the most expensive based on square foot costs, but would also provide the greatest pay-back in future value.

The cost benefit of doing more work in a concentrated area can be summarized in the concept of "economies of scale". We explained to our clients that each individual component of the project costs less when combined into a single, continuous project. The plumber comes once to complete the kitchen addition, the powder room and the bath addition. To break down the incremental costs of adding each floor for a 3 story addition and roofdeck including pilothouse addition:

  • A 1-story home addition is the most expensive (all of the foundation and roofing work for a single story)
  • A 2-story addition is never double the cost of a 1-story addition - in this case, it was about 50% more to add a second story
  • A third story addition was just 40% more 
  • A fiberglass roofdeck addition with pilot house, only 20% more (the roof was already included in the 1 story addition!)

What Could we Fit into the 3 Story Home Addition Budget?

Due to the admirable discipline of the homeowner and a variety of cost effective solutions, we were actually able to fit a LOT into a budget of less than $250,000. On the 1st floor, the kitchen addition included a greatly improved work triangle, more natural light, a breakfast nook, and a new powder room. On the 2nd floor, we designed and built a large bedroom addition for their daughter and configured the floor plan to provide an oversized closet space. On the 3rd floor, we completed a combination guest room/office addition with additional storage and a complete stairway to the roof with an oversized window over the stairwell landing. On the 4th level we installed a pilot house addition which opened to a new walk-able fiberglass roof deck and sporting a cost efficient deck railing system. The interior includes new hardwood floors, increased natural light from large extra windows, and updated lighting throughout. The kitchen transformation included two-toned shaker cabinetry, white quartz counters, a farmhouse sink, brass accents, and reclaimed floating shelves. We also installed new budget-friendly vinyl windows, a sliding patio door, and vinyl siding at the exterior of the new addition.
