Slidell’s housing landscape ranges from older homes near Lake Pontchartrain in Olde Towne and the lakefront communities to newer subdivisions off I-10 and I-12. Older lakefront properties often have larger lots and more architectural character, making additions a meaningful investment. Newer subdivisions have conventional construction but sometimes tighter lots. St. Tammany Parish handles all permitting for Slidell additions. We work throughout all of Slidell’s neighborhoods with the right approach for each housing context.

Yes. We serve Slidell homeowners with home addition services throughout St. Tammany Parish. We work on both the older lakefront properties in established Slidell neighborhoods and newer subdivision construction throughout the city.
Older Slidell homes, particularly those near Lake Pontchartrain and in Olde Towne, often have more architectural character and larger lots but more complex structural situations — pier and beam or raised foundations, older framing systems, and systems that require careful assessment before additions are designed. Newer subdivision homes are more predictable structurally with slab-on-grade construction and conventional framing, but sometimes sit on tighter lots with less available square footage within the required setbacks. We approach each type differently and make that assessment during the initial site visit.
Yes. We manage all permitting and inspection coordination with St. Tammany Parish on every Slidell addition project. St. Tammany’s building department processes are well-defined and we’re familiar with what each phase of the permit process requires.
Yes, in terms of material selection and moisture management details. Elevated humidity near the lake accelerates the deterioration of materials that aren’t specified for these conditions — particularly roofing, exterior trim, and moisture barriers. We specify materials rated for this coastal environment on every addition we build in Slidell rather than using the same specs we’d apply in a drier climate.
