We had a complicated building permitting process in unincorporated King County, WA. The shining beacon on the hill during this process was Dave Huard and his company. They did what they said they were going to do, in time and within budget. There was no question too trifle to answer and Dave went out of his scope to help. We will always be grateful for Dave who kept us sane during this process. We highly recommend him for your project. Pia

Dave Huard knows his stuff. We had two very challenging lots yet Dave was able to design systems that made them both of the buildable. He is also extremely patient. We had multiple revisions to our designs due to challenges with a slope that required adjusting the home footprint several times. At one point, when the design change required new perk holes, he was out of town but sent a family member to hand dig the missing hole to make sure we had what we needed. Later, when we had an additional site plan revision, he gave us the option to hand dig the needed holes (with a hand drawn map) or hire him to come out with his mini-tractor for a reasonable cost.

He keeps his clients informed and gives them choices. Dave is thorough and also well respected by King County. This is really important when navigating the strict requirements and procedures. April is also fantastic. As an example, one time when we had mail stolen that included our final plans, she had new packages in the mail the next day. You can't go wrong with HDSM. Thank you Dave and April.

Dave and April were recommended to us, they were responsive, informative, prepared, and helped us through a process that is always difficult, but in these economic times is down right frightening. I highly recommend their service. Thank you Dave and April. Steve and Christy Cole
