"Shilpa did an amazing job designing an addition to a home we bought. It included remodeling an extra framed garage into a master bedroom suite, laundry room and powder room plus adding to its size . The project also included doubling a great room to blend into the house with the new suite as well as opening up the kitchen to this great room and raising the ceiling . The design blends really well and will provide a nice open plan for living and entertaining I was impressed with how well Shilpa understood what we wanted and executed the plans in the time frame promised if not earlier. She also pushed it thru the planning dept. with minimal need for changes. The project is on going and is moving along well Shilpa is always available to answer questions as things progress. The contractor feels she is easy to work with as well. I really enjoyed working with Shilpa and easy her demeanor ."
