You could hire an architect to create a plan for your renovation or new home construction, but there are some key disadvantages when compared with a design-build service. One, a plan an architect creates may come in way over budget when it comes to construction, and you will have to pay them more money to create a new plan. Second, architects are unable to estimate many of the costs involved with construction, including debris removal, HVAC, lead testing, dust protection, and painting. They also only provide 2D, black and white drawings, so it might be difficult for you to get a full picture of a design before construction begins.
