Home Building questions, answered by experts

The construction stage, which includes pouring the foundation, framing the structure or building the walls if you choose a concrete house, and installing doors, windows, a roof, siding, drywall, and flooring, will almost always take the longest. The planning phase can take just as long if you’re building a custom home, but the finishing process, which includes painting, installing trim, and finishing the interior, will rarely take longer than the previous two phases.

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.

Yes, there are a few different ways you can finance new construction. Some lenders offer new construction loans that cover the building costs and then convert to a standard mortgage once construction is complete. Some custom homebuilders also offer financing options that only require a down payment before you begin the building process. Construction loans are possible, as well, although they typically only cover the building process, and you’ll need to pay in full once the house is completed.

Yes, many kinds of building permits exist for various projects in and outside your home. Each city sets the permit categories, but they typically cover new construction, alterations, and demolition. For example, you will need a different permit to finish a basement than you would tear down the patio.

Most cottage builds take between six months and one year from planning to completion. The timeline includes design, permitting, site prep, construction, and finishing work. Factors such as weather, material delays, and permitting can affect the schedule. Hiring an experienced cottage building contractor and making prompt decisions can help speed up the process.
