We got the same story but the pool builder would not give us a copy of the design to share with the landscaper. They were just interested in getting us to sign the contract as quickly as possible so we couldn't shop around.
We have an apointment with Hamilton-Steele this evening. They are a high end custom builder but their designs look very impressive. They contract out the excavation, steel, plumbing, and gunite but handle everything else in house. Has anyone had experience with them?
