Additional contact name - Dwight Wielenga.

"Horrible, quality of work was horrible, billed me for work that was not even done on my property. Will not take charges off the invoice for the work that was not done. I refuse to pay for work that was not done and they will not return my phone calls to discuss the discrepancy on the invoice and now put a lien on my property even though I paid for the work that was actually done. They will not release the lien or discuss the invoice with me. I would not recommend them at all."

Home Building questions, answered by experts

A carriage house combines garage or storage space with living space, usually in two stories, while a garage generally does not offer any living space. Carriage houses are built with plumbing, insulation, and heating and cooling systems, which are usually features not found in traditional garages. Building codes and insurance requirements greatly differ between the two types of structures, and may make it difficult to convert a garage to a carriage house.

The early stages of building a house are harder than the later stages; laying the foundation and framing the house are two of the most challenging steps. However, it varies for everyone. Some people have difficulty installing HVAC, plumbing, and electricity, while others find it harder to plan the house and secure the necessary permits. 

It is a good idea to check in with your local city and state regulations before committing to building a shipping container home no matter where you live. This concept is pretty new across the country, and many places won’t let you build one.

The International Code Council (ICC) offers guidelines for home builders on the safe use of ISO intermodal shipping containers repurposed as building components, which can be helpful to review when planning or designing a shipping container home.

Local zoning laws and building codes will determine whether you can build a guest house in your backyard. These laws may limit the potential location of the guest house on your lot or the size and look of the structure. If your lot isn’t large enough, you may not be able to build a guest house at all. Speaking with a local home addition company can help you learn about the local regulations and your other options, such as adding an ADU onto the main house.

Home additions can add significant value to a home by increasing its overall square footage and enhancing a home's functionality and appeal. Key additions such as extra bedrooms, bathrooms, or larger kitchens offer the highest returns on investment. Well-planned additions that seamlessly integrate with the existing structure and match the neighborhood's style can boost curb appeal and market value. However, the actual increase in value depends on the quality of the work, the types of additions, and the current real estate market conditions.
