What is a Duplex?
Maximise Value with Seeka
A duplex is two fully self-contained dwellings built on same block, either attached or detached, each functioning as an independent residence with its own amenities. These dwellings can be held under a single title or subdivided into separate titles, allowing for individual ownership, sale, or rental.
More than just practical, a duplex is a great way to double your blocks potential. Offering flexibility for families, added value for investors, independence for relatives, or an income stream through dual rental or sale.
What's Required for a Duplex Build?
Maximise the Potential of Your Block With Duplex Construction
Not every block is suitable for a duplex, but we’ll help you figure it out. Factors like zoning, frontage, access, and lot size all play a role in determining feasibility.
As a guide, duplex developments generally require a block that is at least 500 sqm, subject to local council regulations.
If you're considering building a duplex, Seeka Constructions can assist you in navigating the planning requirements and ensuring your project aligns with the Gold Coast City Council's regulations. Our team can assess your site and provide recommendations on whether a duplex is right for you.
Zoning
Your land must be correctly zoned to allow duplex construction
Setbacks & Coverage
