Custom Home Design

Custom Home Design Services in Sydney & Western Sydney

Designing a new home is one of the biggest investments most people make, and clear architectural planning is the key to a smooth build. Trinity Design & Planning provides custom home design services across Fairfield, Campbelltown , Parramatta, Liverpool, Bankstown, Blacktown, Penrith, Sydney, Inner West and neighbouring suburbs.

Our approach blends creative design with practical compliance, ensuring your home not only looks beautiful but also meets NSW planning requirements and construction standards.

A Tailored Design Experience

Unlike project-home templates, a custom home design is shaped around your lifestyle, site conditions, budget and long-term plans. Whether you’re building on a vacant block, subdividing land, or replacing an older dwelling, we work closely with you to create a design that makes the most of the site while complying with council or CDC controls.

What we consider in your design:

  • Natural light and ventilation pathways

  • Bedroom placement and privacy

  • Family, entertainment and outdoor living needs

  • Street frontage and façade character

  • Site slope, easements and setbacks

  • Energy efficiency (BASIX compliance)

  • Budget alignment with build feasibility.

Concept to Approval - A Clear, Guided Process

We understand the NSW approvals system, so your custom home design is prepared with DA or CDC pathways in mind from day one.

1. Initial Consultation

We discuss your goals, preferred architectural style, functional needs and budget expectations. This includes understanding local council rules for suburbs like Fairfield, Liverpool or Cumberland LGAs.

2. Site & Feasibility Review

We analyse your lot, survey (if available), planning controls, solar orientation and stormwater requirements.

3. Concept Design

You receive initial floor plans, façade concepts and spatial arrangements to review. These are refined until everything aligns with your expectations.

4. Final Architectural Drawings

We produce clear, professional plans including:

  • Floor plans

  • Elevations

  • Sections

  • Roof plans

  • Window schedules

  • Site plan

5. Documentation for DA or CDC
