"I needed a custom porch built on my 1940s home. John and his team handled the project with creativity and sensitivity to the unique situation. Drawings and permits handled quickly, they even utilized bricks I had stored and extended our porch space to match the existing footprint"

"Team was fabulous to work with, hands down. My vision was to add more living space without adding square footage. Expert Home Builders made it happen. Walls were moved, doors rearranged, pocket door installed, custom shelving, new kitchen with extra seating, and new bathrooms came to life. I felt I was part of the Expert team. My vision and their high standards created my perfect place."

"It went great. We have remodeled three houses and always had bad experiences whenever we used a contractor. Kenny, owner of KTD Construction, is hands down the best contractor. His pricing is fair and often less than other competitors. He is always in contact with you throughout the project, which is rare. He is an exquisite carpenter and framer and his crew are all courteous and professional. He is a fast worker, gets the job done right and even hauls all project debris and cleans up after with great attention to customer satisfaction. Our neighbors even commented that it’s hard to find a good contractor and one that works weekends no less. Kenny will also help find sub contractors for plumbing, electrical, drywall, and if they don’t follow through Kenny will see to it that the job gets done on time and to the highest standards. If you are lucky enough to have Kenny on your job you will be a happy homeowner just like us."

"Spectrum One is our choice over and over again for renovating our home, which was built in the 1960s. Dennis comes out and looks at the scope of the project and gets back to you in a timely manner with an incredibly detailed and professional proposal. He takes into account your vision for the home and offers suggestions for improving the project or explains how the team can make that vision come to life. The project managers who oversee the project from start to finish have been diligent, respectful and ensure that the work being done is of the highest standards. They are on-site every day with a whole team working to get the job done as beautifully and as quickly as possible. The attention to detail from the whole group is what I most appreciate. We have used them for whole-home flooring (removal, installation and baseboards), recessed lighting, countertops, backsplash and would trust them with any project. We recently completed a third project with Spectrum One that included widening doorways, redoing an outdated fireplace hearth, and remodeling two bathrooms. Everyone at Spectrum One is quick to respond, honest, creative, and fun to be around. We love them and highly recommend to anyone looking to do a renovation, repair, or build!"

Custom Home Builders FAQs, answered by experts

The average cost to renovate or remodel a home is $52,300, with most projects ranging from $19,500 to over $88,400. However, costs can vary significantly, from as low as $3,000 for a small project to $170,000 or more for a complete home remodel.

Several factors influence the total price, including:

  • Project Scope and Size: The extent of the renovations, whether it's a single room or the entire house.

  • Location: Geographic location affects labor and material costs.

  • Materials: The quality of materials chosen.

  • Room Type: Kitchen remodels ($14,500 - $70,000+) are generally more expensive than bedroom remodels ($1,500 - $5,500).

  • Other Factors: The time of year, complexity of the work, and any additions or expansions.

On a per-square-foot basis, you can expect to pay between $15 and $60 for standard projects and up to $150 for luxury renovations.

Examples of specific project costs include:

  • Basement remodel: ~$20,200

  • Garage remodel: ~$27,900

  • Loft conversion: ~$20,200

  • Disability accommodation remodel: ~$4,300

  • Major home repairs: ~$11,700

If you are financing the project, note that some loan programs, like the FHA 203(k), may require a minimum project cost (e.g., $5,000) and will necessitate a home appraisal and professional cost estimates. Using a home renovation cost estimator can also help you budget for your project.

Craftsman-style homes are predominantly found in the Western United States, specifically in Southern California, where the style originated. Since the climate was mild and there was access to plenty of natural resources, Southern California became a hub for this style at its inception. That being said, if you consult with an architect near you, you can have a Craftsman-style home anywhere.

Framing is often the most expensive phase of building a house because it’s time-consuming and requires a lot of materials. It costs between $20,000 and $50,000 on average, depending on materials and labor costs. Before construction begins, it’s possible that purchasing land is the priciest step in the process. Some plots of land sell for $3,000, while others cost upwards of $150,000.

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 contractor can install your shipping container home in as little as 90 days. This is notably quick compared to a traditional home build, which can take more than a year (providing there aren’t permitting or construction delays that make the wait even longer). For the quickest installation, choose a prefab container home.
