Trusted by homeowners, architects, builders and developers across NSW.

Planning a Townhouse or Multi‑Residential Development?

Townhouse and multi‑residential developments often involve more complex BASIX requirements, approval pathways and stakeholder coordination.

Senica works alongside architects, building designers, builders and developers to provide practical BASIX advice, compliance guidance and sustainability assessments that support efficient project delivery across NSW.

Why BASIX Matters for Multi‑Residential Developments

BASIX plays a critical role in the approval process for many townhouse, villa and multi‑residential developments across New South Wales.

Early consideration of BASIX requirements can help project teams identify practical compliance pathways, minimise redesign risk and avoid unnecessary delays during planning and approval stages.

By integrating BASIX requirements into the design process from the outset, development teams can make informed decisions that support compliance, sustainability outcomes and project feasibility.
