Custom Home Builders questions, answered by experts

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. 

Ranch and colonial-style homes are often the most affordable to build. They have a common layout with available designs that are easy to adjust in simple ways without having to spend too much on a structural engineer or architect. Both types of homes' symmetry, simple roofs, and often one or two-story plans mean they often fall in the $150 to $200 square-foot range, putting them right around average.

Custom homes can take an average of 18 months to build, mainly due to the lengthy design process, and most projects take somewhere between 12 and 24 months. When you work with the right custom home builders near you, they can help you map the road ahead and understand what can speed up or delay the timeline. Choosing locally available materials, for example, can speed things up without losing that customized touch.

How long it takes to build a log cabin depends on a variety of factors, including its size and design, and whether or not you have to clear the land. Construction can take a few weeks for a prefab log cabin on an established site, but up to eight or nine months for a custom cabin on undeveloped land. In comparison, the timeline to build a house is typically four to 12 months.

Modular homes are a type of prefab home. Specifically, manufacturers first build modular homes in sections and then deliver them to the job site. The modules, or sections, are usually at least 70% finished before they arrive on your property.

In comparison, prefab homes arrive in panels or segments, and workers assemble them on-site. Generally speaking, modular homes tend to be more durable, and their consistent construction standards may mean you’ll have an easier time getting conventional home loans.
