H&H designed our dream home in Bonnie Brae. They took a 1937 Tudor and updated it with a fabulous kitchen with a giant island, additional bedroom and master bath. The job required significant structural work to relocate the stairs. I would trust John and his team with any project. Meticulous, courteous and honest. And, beyond all that, my neighbors all were very complementary regarding how they left the job site so clean. Could go on and on but we have been enjoying our house for two years with no issues and feel it is now even more solid than when it was originally built. They are on schedule, transparent and accurate with budget, on site project management, quality craftsmanship (Joe and Tyler) very organized, good communication and creative design ideas from Michael.
