Building a new structure or addition is an immensely complex process. From getting a building permit to designing a blueprint, you really can’t build your own pool house unless you have an architectural or engineering background.

Adding a pool house can bring equity to your home, but a poorly-constructed house can do the exact opposite. Work with an architect near you to start planning.
