    "We have been working with Todd Willoughby since early in 2018. We had purchased a piece of land along the Chesapeake Bay and wanted to build a small but thoughtfully designed contemporary garden cottage for our retirement. After speaking with a number of architects we chose Todd and we have been very happy with that decision. Over several months, we worked have closely with him through the several design phases, culminating in a very complete set of construction documents, that we are now using for bidding. Throughout the process, we have found Todd to be personable, smart, perceptive and creative. He has been able to translate our ideas into working drawings that one of the contractors noted was called the most detailed he has ever seen. Todd has captured our vision for an environmentally friendly house with solar and rainwater harvesting. We have met with him many times talk through the many details, choices, and constraints you inevitably face. He has done all the coordination needed with the other specialties the engineers, surveyor, and solar energy firm. Having enjoyed this first part of the collaboration, we are hiring Todd to help us through the bid evaluations and construction admin phases. The best recommendation would be our actual house, but until we get there we can say Todd has done an excellent and professional job getting us this far, and we look forward to working with him through to a completed project."

    "Alex and Svetlana line are a real pleasure to work with. They were flexible and informative in the planning and offer this multiple options. They were flexible with changing the project while it was under way, both addding an extra task and deleting two tasks. The work occurred on schedule and the cruise that they sent were efficient, friendly, and very good at cleaning up the work site every day. It was an entirely positive experience and we are preparing another request for more work from them."

    "Working with VHR was overall a great experience with a great outcome. The project was to completely gut and redo a 1955 bathroom. We selected VHR for three reasons 1) competitive in price although not the very lowest 2) flexible, knowledgeable, easy to work with and a had a great attitude 3) website and pictures of past projects showed great work The project took quite some time from inception to completion, but this was all our doing. We ordered several things (ie vanity related) that were custom built that took weeks to come in. The VHR team worked around this very well. When things were ready for them, they were there. The team was hard working and very knowledgeable. They kept the house and working environment clean. For example, they put runners on our carpet and floors and they cleaned up well in the evenings. We had numerous changes to the plan mid-stream and they were always accommodating. Some changes they charged for and others they didn't. Extra charges were discussed upfront and were very much in line with the amount of extra effort. They asked us questions when decisions arose and got our concurrence before proceeding. For example, for the height of the shower-head and towel rack, they taped them in place so we could adjust as necessary before they installed. Once complete, they came back afterwards to fix some small items we noticed after the fact. The before and after is incredible. The bathroom look great and works fabulously. I would hire them again in a minute and will hire for my next set of projects."
