We recently had the general contractor who built our first home make a renovation to our second home. Once again, Royce did an exceptional job on the remodel. He also helped with the design and I must say it came out beautiful!

Andy put a foundation under a portion of this house. It required just about every trade: electrical, plumbing (gas), drywall, plus big beams which went under that section and were jacked up. He and his guys did a great job. He handled it all and passed inspection with no problem.

Home Building questions, answered by experts

The requirement for building permits varies by location, but most building departments will require permits for any changes to the structural components of a home. They’ll also require them for changes to the plumbing, electrical, and HVAC components, as well as any permanent improvements to the land, including concrete patios or foundations for additions or outbuildings. You also might need permits for things like roof replacement and window replacement, depending on your local government.

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.

The average build timeline for a home is between six and 12 months, with timelines pushing toward the upper end of that range if you’re creating a custom design or need a lot of land preparation before getting started. Hiring a general contractor or a custom homebuilder will help speed up the process, as you’ll see fewer delays between different parts of the build process getting done.

Green homes are often more expensive to build, averaging around $200 per square foot compared to the $150 per square foot you’d spend to build a standard home. However, green homes can save you money on your utility bills by consuming less energy or creating energy using solar panels or wind turbines on-site. They’re more expensive to build, but they often end up costing less in the long run.

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.
