"After dealing with frequent roof repairs, we finally decided on a complete replacement for our Livermore home. Avi kept us informed every step of the way, and the finished roof exceeded our expectations. It's made a noticeable difference during hot summer days."

"I hired LA Expert Builders on ADU Garage Conversion. It wasn't a simple project, but Nir and his well organized crew made it simple as possible. Nir was very honest and he carefully listened my requests and did everything as I wanted. His team was very respectful to my home, they kept working area very clean and they were also very respectful to me and my family. The project went unexpectedly smooth with no issues and was finished ahead of schedule. I'm impressed how everything turned out, just perfect! Thank you Nir and thank you LA Expert Builders!"

"Our outdoor barbeque/kitchen in the pool area was just done by Best Builders Group who was referred to us by a co-worker who hired them for his last remodeling project at his house and he was very happy with everything they did. Our remodeling project was a large scale remodeling project to our opinion BUT to Best Builders Group it was a normal size project and they provided all the required attention to detail and great working capabilities. We had some concerns on the plumbing & electrical but Zohar took care of all of them in a very professional manner. Part of the work was to build a custom fire pit and Zohar was always nice enough to do whatever we asked. All the workers on the other hand… always made sure to clean up & they never left the house without the cleaning task. The installations was done perfectly, professionally, clean and with perfection. This remodeling project came out to be such a wonderful entertaining spot of the house and I strongly recommend them."

"Perfect!!! We originally d to repaint the whole house. Since that was out of our budget, we asked Tony to touch up our walls. When he finished, it looked like we had brand-new walls!!! Although it's the same beige color we already had, they look spectacular!!! He did the whole house in about 6hrs."

"We wanted to build an addition onto our house on a budget. After researching dozens of contractors Green America Builders was the obvious choice. Crew was fantastic, always kind and curious and best of all, he came in on-time and under budget. We could not be happier with America Green Builders!"

"Cielo Construction has completed several projects in our house including the remodeling of our guest bathroom, master bathroom, kitchen and living room area. The design and remodeling was a custom European style/modern while the bathroom included a walk in tile shower, jet shower system, home automation and more… part of the design was to reposition the door opening for a much better use of space. Cielo construction staff helped us by selecting all of the finish materials including the tiles, upper and lower cabinets, accessories and more… including the color/style of the paint. Mike included also in his work the remodeling of the guest bathroom, drywall, type of texture, baseboards etc. He has excellent, professional craftsmanship and creativity skills. Cielo constructions approach and talent to meet our deadlines were fantastic and he was able to finish the remodeling project on time. We definitely recommend Cielo Construction and all the involved people that worked at our house for any type or style of construction or remodeling projects. We are very pleased with the completed project and we will hire them again for more upcoming projects. Thanks Cielo construction for a great job from a very happy customer."

"I had an excellent experience with Ocean Seven Builders that I wanted to share with the google community. I had a kitchen and 2 bathrooms remodeling project, and I had no idea where to start. I interviewed a few companies but Eli, from Ocean Seven Builders, was super informative, honest and straight-forward. Throughout the entire project, communication was great and they always kept us informed and updated on the progress. Whenever we were uncertain about a decision, they patiently walked us through the options and made sure we were happy with the results. Also, Eli and her team were extremely conscientious about issues that came up and dealt with every issue calmly and efficiently. To sum it all up, From booking an appointment through having the job completed, Ocean Seven Builders was fabulous to work with. They were responsive, courteous, and displayed a high skill level throughout the entire project. The finished result looks very high end and we managed to stay on budget. Thank you Eli and Ocean Seven Builders for my lovely new home."

Custom Home Builders FAQs, answered by experts

The longest part of building a custom home is the design phase. It takes multiple professionals and a ton of work to bring your vision for your dream home to life while sticking to a homebuilding budget and also ensuring everything is built to code. Expect the design phase for a custom home build to take six months to a year.

Most cottages are around 1,000 square feet, making them smaller than most other styles. However, cottages are defined more by their decor and architectural focus on simplicity, functionality, and a connection to nature than they are by a rigid square footage or floor plan. While cottages are defined more by their charm and appearance than size, the smaller footprint does help maximize the comfort and charm, and it keeps the focus on connection to nature and family.

A carriage house is a freestanding building, while a townhouse is connected to other units. A townhouse is a full single-family home and typically shares a parcel of land with other connected homes. A carriage house is rarely used as the sole single-family home on a property and is most often an additional building sharing property with a traditional single-family home. 

A green home is one that focuses on conservation, with the goal often being net-zero carbon emissions and self-sustainability. It will often include some kind of self-generation equipment, like solar panels or a small wind turbine, high-efficiency electrical components and mechanicals, and high-quality insulation and air sealing to reduce the loss of conditioned air. Many green homes also include xeriscaping or rainwater collection to cut down on drainage and water consumption.

The term “cottage” is subjective, so there’s no rigid definition, but it generally refers to a small home with simple and purposeful architecture that embraces nature and focuses on charm over everything else. Cottages are typically 1 or 1 1/2-stories tall, usually with gabled roofs, and are built out of natural materials that help make the structure a part of the surrounding nature rather than something that stands out from it. A big part of what makes a cottage a cottage is the decor, which includes natural materials from the nearby area.
