Riversedge Building Group works across Mullumbimby and the wider Brunswick Valley — Main Arm, Wilsons Creek, Federal and the rural pockets toward Goonengerry. We deliver new home builds, renovations, extensions, carpentry and project management, with the same licensed builder quoting and delivering each project.

Mullumbimby is a river town, and that defines a lot of the building work here. Much of the township sits on the Brunswick River floodplain, so flood-planning levels routinely set minimum floor heights and influence whether raised-floor or pier-and-beam construction makes more sense than a slab. The town also holds a stock of older character homes worth renovating sympathetically. We build under NSW Builder Licence 345758C and design to the flood and character realities of each block from the start.

Byron Shire Council flood-planning pathway in Mullumbimby

Residential work in Mullumbimby is assessed under the Byron Shire Local Environmental Plan and Byron Development Control Plan, and the flood-planning overlay is often the controlling factor. Where a lot sits below the flood-planning level, the council generally requires habitable floors to be set at or above that level, which affects the choice between slab and raised-floor construction and can shift a project from Complying Development onto a Development Application pathway. We obtain the flood information for your property early, design floor levels and structure to suit, and confirm the correct pathway before any contract is signed.

Renovating character homes in the Brunswick Valley

Mullumbimby has a strong stock of older timber and character housing, much of it raised on piers — well suited to renovation and extension when handled with care. We work with these homes' existing structure, levelling and re-stumping where needed, matching profiles and detailing, and integrating new wet areas, kitchens and additions so the result reads as a coherent whole rather than an obvious bolt-on. Where flood levels apply, raised-floor construction often complements the original house rather than working against it.

Frequently Asked

Questions

Do flood levels affect building in Mullumbimby?
Often, yes. A large part of Mullumbimby sits on the Brunswick River floodplain, so Byron Shire Council's flood-planning overlay frequently sets a minimum habitable floor level for new work. That can favour raised-floor or pier-and-beam construction over a slab and may change the approval pathway. We pull the flood data for your specific lot before design so floor levels and structure are correct from the outset.
Is a raised-floor home a good option in Mullumbimby?
On many Mullumbimby blocks it is, both because it can lift habitable floors above the flood-planning level and because it sits naturally alongside the town's existing raised timber housing. The right choice still depends on your lot's flood information, soil and budget priorities, which we assess before recommending a slab or raised-floor approach.
