While you do pay extra for interior design services one should not assume that there is no cost to doing it yourself. Buying the wrong pieces, spending money and the room not coming together in the end, not knowing about diverse products at diverse prices or making choices that don’t work all come at a cost. A project also takes many hours and many weekends and that time comes at your own labour cost. Hiring an interior designer helps to avoid wasted time and money due to mistakes and their involvement in a project results in a better end result than most people could achieve on their own. An interior designer will also be entirely dedicated to completing the project and has buying power with suppliers resulting in quicker snag resolution and you finally getting the project complete.
