"I wanted to construct and extension on my home so I called Arius and the engineers came out and assessed my property and proposed a few different options that meet my needs. They helped me select the optimal design which meet my needs and within my budget. The design and construction was executed flawlessly and remained within our pre negotiated price and schedule. I was very pleased with their work."

"Excellent. John with Sullivan Home Interior Products was a breath of fresh air from previous experiences.He came in prepared and arrived punctually and completed all the work in the estimated time he had given me. The work area was as clean if not cleaner than when he arrived. I am so glad to find a company local that can provide these services. I will definitely be using him again and telling all my friends, family and neighbors"

"We had numerous seam repairs in our ceilings and then I wanted all the ceilings painted.
 The workman was meticulous about keeping everything as clean and dust free as possible.
All areas were shrouded in plastic sheeting and all floors were protected.
He arrived on time, and worked longer each day than I expected.

Custom Home Builders FAQs, answered by experts

It pays to hire a project manager or general contractor when you have a large-scale project that will take over a week to complete, especially when it involves structural changes and multiple subcontractors. This includes hiring a general contractor to build a house, add an extension, or manage other projects that need a building permit.

The average cost to build a modular home is around $270,000, and most modular homes total between $180,000 and $360,000. Of course, this price varies significantly by location, and the price tends to follow the cost of living in the area. There are quite a few other factors at play that can affect your pricing, including the following:

  • Number of bedrooms and bathrooms

  • Site preparation, including land clearing and leveling

  • Type of foundation

  • Utility connections

  • Cost of building permits

Start by researching local contractors with experience in cottage construction. Ask for references, check licensing and insurance, and review completed projects. Compare multiple bids, making sure each includes the same scope of work. A good contractor will communicate clearly, provide a detailed contract, and ensure all work meets code and safety standards.

Whether a prefab home is worth it or not will depend on your personal needs and preferences. Overall, prefab homes tend to cost less than traditional homes, although they also tend to have lower resale values. Another thing to consider is that prefab homes usually last 50 to 60 years or longer, while traditional homes last 50 to 100 years or more.

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.
