Expert Building Design in Mountain Lagoon

Tucked between Bilpin and the edge of Wollemi National Park, Mountain Lagoon is known for its serene wilderness setting, crisp mountain air, and complete disconnection from the urban pace. With limited infrastructure, high bushfire risk, and large, often sloping blocks, designing here requires a unique approach that balances sustainability, council compliance, and resilience.

At DMR Designs, we specialize in drafting services, council approval assistance & building design in Mountain Lagoon. Whether you're planning a sustainable mountain retreat, a bushfire-resilient primary dwelling, or a nature-inspired getaway, we deliver tailored solutions that work with the land—not against it.

We proudly serve Mountain Lagoon and surrounding high-country suburbs with designs that combine rural charm and expert-level compliance.

    • No access to mains power, water, or sewer

    • Fire trails, access roads, and staging required

    • Environmental overlays often apply

    • Limited mobile reception and remote communication challenges

DA vs CDC: What’s Right for Your Mountain Lagoon Project?

A Development Application (DA) is required due to the rural zoning and bushfire risk.

Here’s a quick breakdown to help you understand the difference:

DA (Development Application):

  • Required for all new dwellings or structures

  • Includes fire safety assessments, ecology reports, and slope analysis

CDC (Complying Development Certificate):

  • Not applicable due to environmental constraints and fire risk
