A small Construction sole proprietor, shop & office at my home 2 mi north of Mankato. I have been in business 20+ yrs have done all types of construction & willing to take on almost any project. I plan, price, contract, & service all projects with experienced professionals, while being licensed & insured, dependable & honest.

"The room was completed on schedule but they did not complete all of the work the were supposed to do. The bathroom was completed but they installed a piece of the wall covering with a large chip in it and installed the bathroom stool incorrectly that caused it to leak. I contacted Rick many times via text and he responded that he would call to set up a time to correct my problems. He never called me back or tried to contact me."

Home Building questions, answered by experts

In most states, you can build an in-law suite on your property as long as you follow local building codes. However, it's important that you have enough space on your property to accommodate the new structure. A functional in-law suite in your backyard will require between 300 and 800 square feet of space.

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.

The number of rooms a guest house should have really depends on your needs. A small guest house might only need one bedroom, a bathroom, a living room, and a kitchen. Larger units may have multiple bedrooms and bathrooms. Your local building codes may limit the number of rooms or square footage you can have in a guest house.

Shipping container homes last at least 25 years on average, but they can last even longer with proper maintenance. Since shipping containers are made from metal, they’re quite vulnerable to rust and corrosion. This issue is exacerbated in coastal areas or areas with a lot of precipitation. To extend the life span of your container home, install siding that protects the exterior. 

On average, exterior brick siding costs around $18,000 for a 2,500 square foot home. Whereas vinyl costs around $11,000 and engineered wood costs around $4,000 for the same size home. You also need to account for the cost to paint the material afterward.
