Request a House Plan Modification

The modifications department at Frank Betz Associates, Inc. works with builders to customize our plans to meet your exact specifications.

Builder Modification Request

Select a home plan, then describe in detail how you would like the plan modified. Our expert staff will analyze your request and advise with regard to the effects of the modifications and produce an estimate of the work required to create your new plan.

Our basement foundation is designed as a walkout style, which consists of three masonry walls and one wood framed wall with windows and doors. Interior walls are wood framed. Any other type of basement is a modification and needs to be described in your Wish List at the bottom of this form.

Some areas have height restrictions. This may be a result of zoning ordinance or a subdivision covenant. Consult with your local building officials to determine if height restrictions apply in your area.
