Yes, you can DIY and look professional! We recently moved from downtown Philly into our new carriage home in the nearby suburbs and brought our modern style and design with us. Our carriage home is about 3K sq feet and we've updated the kitchen, living room, breakfast room, office and powder room to match our modern style. We installed new wide plank wood floors, a modern linear fireplace, slate wall with wooden mantle, and re-did the downstairs bathroom with a modern stone wall, rectangular sink and LED mirror. Please let us know your thoughts and feedback.
