"Landmark Construction provided us with an amazing customer service throughout the process of the remodeling from start to end. Their prices were very competitive. It doesn't get much better than this. We were having foundation work done on my elderly mother's home in LA. We arranged this remotely via a friend that recommended us to Ezra and Charlie. Ezra took time, care, and patience to make sure that the remodeling will be comfortable with the process and to answer each and every one of our questions. This alone makes us recommend them as highly as possible. Customer service of this level is very very rare today. The work that they did was managed by Charlie. Charlie brought his 3 men team and made sure they will do an amazing work and as fast as they could.  I would use this company again without any hesitation. I'd give 6 stars if I could.

"I was selling my townhouse and the roof came up during the home inspection. I called several companies and received comparable quotes from each, but decided to go with Ocean Seven Builders. I'm glad I did. Jimmy, who estimated the job for me, was knowledgeable and gave me an approximate time frame for completion (1-2 weeks). This was an important aspect since closing was scheduled to happen in 3 weeks. After I put down my 1/3 deposit, they ended up having am opening in the schedule and were able to replace the roof within a week's time. The work took less than a day and the crew worked well. They took pictures and provided me with the invoice & warranty documentation I needed for closing. Invoicing and everything else behind the scenes was handled via email with the office manager. He was also very pleasant to work with and provided great customer service when I need the additional documents/info for settlement. Overall, the quality of work and customer service was exceptional. If in the future, my new home needs some roofing work, I would happily use Ocean Seven Builders again."

"Ask to work with Rafael, if you're in Seattle, he's a true professional. He takes pride in the relationship he builds with his customers and has a team that is meticulous and extremely fast. They came in and painted the exterior of my home and the quality of the team's service was nothing short of outstanding."

"The work done was very high quality at a reasonable price. Michae and his team are extremely knowledgeable, professional and efficient. They ensure the job is done well and they do not cut corners. I was thoroughly impressed and satisfied with the work done on my home. If you are looking for a team to do a job for you that you can trust, I would HIGHLY recommend Michae and his team. I will be hiring them again in the future if I need more work done, without a second thought. It’s hard to find a team that you can trust to do excellent work. I am beyond fortunate that I found Michae and his team!"

Custom Home Builders FAQs, answered by experts

While it’s never too early to start planning for a major home improvement project like a home addition, give yourself at least a month or two to plan and design your addition, find a contractor, and get the permits in order. For larger projects like a second-story addition that require designing with an architect, plan on three to four months of preparation.

A-frame homes are on the smaller side. While there’s no set square footage amount it has to be, it will usually come in around 1,000 square feet or smaller.

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.

Yes, you can finance new construction, though the process often requires a different type of loan than one for an existing property. There are several financing options available:

  • Construction-to-Permanent Loan: This is a common option where a single loan covers the building costs and then converts into a traditional mortgage once construction is complete and you move in.

  • Construction Loan (Stand-Alone): This type of loan provides funding only for the duration of the construction project. Once the house is built, you will need to pay the loan in full, typically by securing a separate, standard mortgage.

  • Builder Financing: Some custom homebuilders offer their own financing options, which may only require a down payment to begin the building process.

  • Bridge Loan: This can be a useful short-term loan to fund your new construction while you are in the process of selling your old home.

  • Home Equity Options: If you are building a second home, you might be able to use a home equity line of credit (HELOC) or a cash-out refinance on your current property.

It's also important to be aware that some lenders may have restrictions on financing for DIY house builds, so be sure to verify that you can secure financing before starting your project.

Check reviews, compare quotes, and verify licensing. Ensure the builder has experience with modular construction.
