Added 900 sf and huge patio. All his insights were right. He recommended taking out bookcases and adding windows to Living Room. He also recommended raising the center of the ceilings in LR and DR.....added a 12 foot tall hallway to connect old part to new part......looks like a brand new house and feels great! **★★★★★ — Distinctive Mantel Designs, Inc., Aug. 2013** > I have worked will WJ DeMaio on multiple projects. He is an extremely professional and forward thinking architect. Our collaboration on fireplaces and stone mantels has only improved our product and reputation. **★★★★★ — edwardthomas, March 2013** > Bill DeMaio created the most liveable work of art I have ever witnessed . We have lived in this home since 1972 . We raised our family in some tight spaces in the home but did OK . When we had the opportunity to expand and create a more comfortable living experience , we hired Bill to create just that . Bill was hands on daily and made sure everything was perfect . People come into our home and marvel at how the expansion was done and still appears to be the original design . All of the woodwork was preserved and you cannot tell where old existed and new begins . It doubled the value of the home and more than doubled our pleasure of it . It will never leave our family . Our children and grandchildren have confirmed that someone will care for the home after we are gone . They are just wondering about the time frame . Their bags are at the door . **★★★★★ — vosslerb, Feb. 2013** > We hired WJ DeMaio & Assoc to design the addition to our 100 year old home in Park Hill. We were hesitant to remodel because we did not want to destroy the integrity of our home. We met with Bill DeMaio and his design enhanced our home and the addition blended so well that neighbors commented that it looked like it was part of the original home. We are so happy with our "new" 100 year old home! We highly recommend WJ DeMaio & Assoc and will use them in the future! **★★★★★ — annandmargo, Feb. 2013** > I am pleased to have the opportunity to recommend the best architect I know, Bill DeMaio..Since this format requires a project date, I am listing the most current, but I have worked with Bill DeMaio on eleven projects over the course of the past twenty years and wish to speak about my experience over time. > > The projects have been varied in nature and cost. The tasks have ranged from with historic preservation to residential renovation to new residential and commercial construction. Most project costs have ranged from $100,000 to $300,000. > > With Bill’s guidance, I renovated two historic properties in West Virginia. The first involved adding a large gathering room to an 1890s farmhouse operating as a bed and breakfast. The end result was a seamless addition which looked as if it had been there since the house was built. The second was the renovation of a general store circa 1896. This building was subsequently listed on the National Register of Historic Places, thanks to his attention to historic detail and ability to update while retaining the ambience of the period. > > Over the years, Bill has designed a number of new cabins for me which were used as rentals or sold to people who wanted second homes in the mountains. He has a keen sense of what people want in a vacation home. At the same time, he is mindful of budget limitations on all projects and is able to create a desirable product at a reasonable cost. He does not sacrifice quality but often suggests less expensive ways to achieve a look I want. > > One of Bill’s special strengths is that he works well with contractors—even those who are initially apprehensive about working with an architect. He wins them over as soon as they see that he treats them with respect and values their expertise and experience. > > In 2011, Bill designed a 2,000 sq. ft. yoga studio for me in West Virginia. That studio has become something of a community center in the area. The interior is welcoming, light filled, and has clean lines; the exterior is attractive and was designed to fit the rural setting and proximity to other farm and historic buildings. > > This year, Bill is designing an addition to and renovation of a home I have in Florida. As always, I am impressed with his ideas and his communication skills. One of the qualities I value most is his capacity to really listen to the client and to understand how that client will live or work in the structure he designs. He has infinite patience, is not prescriptive, and helps you get where you want to go. I always learn something. He thinks in a way I would not; he helps me sort out my priorities and stay within my budget. I recommend him without reservation and would consider any client fortunate to have his help. ## Selected projects - [Jared & Thalita](https://www.houzz.com/hznb/projects/jared-and-thalita-pj-vj~6926740) - Location: Not specified - Photos: 1 - [New Denver Residence](https://www.houzz.com/hznb/projects/new-denver-residence-pj-vj~6765975) - Location: Not specified - Photos: 4 - [Lost River Houses](https://www.houzz.com/hznb/projects/lost-river-houses-pj-vj~6475866) - Location: Not specified - Photos: 2 - [Renovations and Additions](https://www.houzz.com/hznb/projects/renovations-and-additions-pj-vj~195020) - Location: Not specified - Photos: 15 - [Mountain contemporaries](https://www.houzz.com/hznb/projects/mountain-contemporaries-pj-vj~113595) - Location: Not specified - Photos: 8 - [Bonnie Brae tudor](https://www.houzz.com/hznb/projects/bonnie-brae-tudor-pj-vj~34383) - Location: Not specified - Photos: 1 [See all 6 projects](https://www.houzz.com/professionals/architects-and-building-designers/wj-demaio-and-assoc-inc-pfvwus-pf~813814339) ## Ideabooks - [Donato Residence - Lost RIver](https://www.houzz.com/ideabooks/181882022/list/donato-residence-lost-river) — 9 ideas - [Wish List](https://www.houzz.com/ideabooks/173126893/list/wish-list) — 1 idea - [liv rm](https://www.houzz.com/ideabooks/155041723/list/liv-rm) — 1 idea - [Summit House](https://www.houzz.com/ideabooks/144944118/list/summit-house) — 44 ideas - [506 Milwaukee](https://www.houzz.com/ideabooks/80681871/list/506-milwaukee) — 20 ideas - [Robertson](https://www.houzz.com/ideabooks/102274675/list/robertson) — 8 ideas - [Oswald-Earl Residence](https://www.houzz.com/ideabooks/34592352/list/oswald-earl-residence) — 92 ideas - [Yousef Residence](https://www.houzz.com/ideabooks/82222995/list/yousef-residence) — 4 ideas - [Barry Conaty](https://www.houzz.com/ideabooks/51249018/list/barry-conaty) — 1 idea - [Metzel Residence](https://www.houzz.com/ideabooks/33547620/list/metzel-residence) — 13 ideas - [Easthaven Landscape](https://www.houzz.com/ideabooks/5656926/list/easthaven-landscape) — 14 ideas - [Wilson](https://www.houzz.com/ideabooks/5446413/list/wilson) — 20 ideas [See all 12 ideabooks](https://www.houzz.com/ideabooks/users/bdemaio) --- *Source: Houzz professional profile.
