Mandeville’s housing ranges from older properties in Old Mandeville near the lakefront to large custom homes in the subdivisions along Highway 22 and Highway 1088. Lakefront properties in Old Mandeville sometimes have specific considerations around elevation, flood zone requirements, and architectural compatibility that need to be addressed in the planning phase. Newer subdivision homes offer more conventional addition paths with larger lots that can typically accommodate meaningful expansions. We work throughout all of Mandeville’s housing contexts with the experience each requires.

Yes. We serve Mandeville homeowners with home addition services throughout St. Tammany Parish. Mandeville is one of the Northshore markets where we build to a premium standard, given the quality of the housing and the expectations of homeowners here.
Yes. Properties in Old Mandeville and other areas close to Lake Pontchartrain may be in flood zones that affect how additions are designed and built — particularly elevation requirements and the specifications for materials that will be exposed to elevated moisture levels. We check flood zone status during the planning phase and factor those requirements into the design and material specifications before any scope is finalized. Building in a flood zone without accounting for those requirements creates compliance problems and insurance issues that are expensive to fix after the fact.
Yes. We manage all permitting and inspection coordination with St. Tammany Parish on every Mandeville addition, including flood zone compliance documentation where required.
Master suite additions are the most common in Mandeville’s custom subdivision market — adding a well-appointed primary bedroom and bathroom that matches the quality level of the rest of the home. Room additions, bonus rooms, and in-law suites are also common. In Old Mandeville, rear additions that respect the character of the existing home while adding meaningful square footage are a frequent project type. We discuss what makes the most sense for each specific property during the site visit.
