Retaining walls Reservoir
Reservoir is one of Melbourne's biggest northern suburbs and there's no shortage of retaining wall work going on. Subdivisions, renovations, side returns, level changes, new pools, new driveways. Kosta & Sons builds retaining walls in Reservoir that match the job. Small garden walls, structural builds holding back metres of fill on dual occupancy sites, and everything between.

Reservoir blocks vary a lot. Older post-war homes on standard quarter-acre blocks, subdivided sites where retaining is part of the development plan, and modern renovations needing tidy boundary walls. We know the area, the soil, and what Darebin Council expects on permit applications. That makes for cleaner approvals, fewer back-and-forths on site, and walls that look the part once everything's finished.
Retaining walls do more than hold back dirt. Here's what they actually deliver on a Reservoir property:

Yes, subdivision work is a regular part of our Reservoir jobs. Whether you're a developer dividing an existing block or a homeowner on a newly subdivided lot, we build retaining walls that meet the requirements of the development approval and Darebin Council's planning conditions.
Yes, and this is common on Reservoir blocks where neighbours sit at different levels. We handle boundary retaining walls, including the conversations with neighbours where needed, and make sure the wall complies with council setback and height requirements. We'll let you know upfront if the wall needs neighbour consent or a council permit.
A good retaining wall has free-draining backfill behind it, an agi pipe at the base to carry water away, and proper outflow to stormwater or a soakage point. Skipping the drainage is the most common reason cheap walls fail inside ten years. We build every wall with the drainage as part of the job, not an optional extra.
Yes, we do that often. Renovations in Reservoir frequently involve a builder running the main job, a landscaper doing the surrounds, and us handling the retaining. We coordinate timing and access so the retaining work slots in cleanly without holding up other trades.
