We had a very negative experience with them. We fired them.
As a couple, we found the process to be awkward: the architects, with Treff LaFleche as the main contact person, didn't listen to many of our wishes and instead kept pushing certain features that we repeatedly said we didn't want.
We also found the billing rates and hours to be very high. We even had almost comical arguments about the size of the project with many discussions about gross vs. livable space, even though all that was stipulated in the contract, and we had thoroughly scoped the anticipated cost of the project.
After my wife became frustrated and then sketched out on her own what she wanted, we realized that we had the wrong architect. He was designing a house that he wanted vs. what we wanted.
So, just after we fired Treff, we both felt incredibly relieved. He was imperious and didn't want to listen to us. Later, we learned that a friend of ours decided not to work with LDa; she said that Treff seemed very distracted.
We later found a new architect, who proved to be amazing: very responsive, an open and positive attitude, listened carefully to us, and billed us at very "fair" rates and hours. We got the design we wanted, almost zero heartburn, and at a fraction of the cost of LDa.
His name is Tim Blanchard. If you call him, feel free to mention my name.
Edit, April 2017:
1. A few Yelpers contacted me, also lodging negative experiences with LDa. Here is a DM from one: "I can't remember whom we talked to, we kept being pushed around." Yup, they're pushy.
2. Please note that Houzz reviews are a sham. The vendor must approve them. Mine was never approved.
3. LDa's Facebook reviews are thin: They comprise of me, a photographer whom they hire, and some random users. read more
