Why Choose JS Construction as Your Class 1 Townhouse Builders Sydney?

Building a multi‑unit development is complex – from council codes to construction sequencing. As leading home builders in Sydney, we have the expertise to deliver turnkey Class 1 townhouse projects. Here is what sets us apart.

1. Total Compliance with NCC & Council Codes

Class 1 townhouses must meet strict Building Code of Australia (BCA/NCC) requirements for fire safety, sound insulation, and accessibility. We handle all Development Applications (DA) or Complying Development Certificates (CDC) and ensure every unit meets council specifications. Read our FAQs about approvals for multi‑unit developments.

2. Maximise Land Value, Minimise Wasted Space

We design townhouses that fit your block perfectly – whether it’s narrow, sloping, or irregular. Using split level home designs and narrow lot home designs, we maximise the number of dwellings without compromising liveability. See our fixed‑price tenders for multi‑unit projects.

3. Turnkey Construction – From Earthworks to Handover

As a full‑service construction company, we manage everything – site preparation, demolition (if required), foundations, framing, finishes, and landscaping. You get one point of contact and total transparency.

4. Investor‑Focused Design

We build townhouses that attract quality tenants and command premium rents. Private courtyards, off‑street parking, modern finishes, and energy‑efficient features are standard.

5. Flexibility for Dual Occupancy & Knockdown Rebuild

Many of our townhouse projects start as knockdown rebuild on an existing block. We can also integrate dual occupancy homes where zoning allows – giving you even more flexibility. Explore our dual occupancy home designs.

Our Class 1 Townhouse Development Process

We follow a proven, five‑stage process to deliver your project on time and on budget.

Step 1: Site & Feasibility Assessment

We analyse your block’s size, zoning, floor space ratio (FSR), height limits, and setback requirements. We also check for easements, bushfire attack levels (BAL), and heritage overlays. Contact us for a free feasibility assessment.

Step 2: Concept Design & Town Planning

Our in‑house designers or your architect create a concept that maximises dwelling numbers while meeting council codes. We then lodge DAs or CDCs and manage all council negotiations.

Step 3: Fixed‑Price Tender & Construction Contract

You receive a detailed, line‑item fixed‑price contract. No hidden costs. No surprises.

Step 4: Construction & Project Management

We build all townhouses concurrently, using digital project management tools so you can track progress in real time. Regular site meetings and quality inspections ensure a premium finish.

Step 5: Handover & Post‑Construction Support

We walk you through each completed townhouse, provide warranties and maintenance guides, and remain available for any post‑handover queries. Read why JS Construction is an award‑winning builder in Sydney.

Class 1 Townhouse vs. Dual Occupancy – What’s the Difference?

Both increase land yield, but they serve different purposes.

Class 1 Townhouse (Multi‑Unit Development)

  • Three or more attached dwellings on one title (e.g., townhouse complex).
  • Each dwelling has its own entrance, courtyard, and often separate meters.
  • Ideal for developers and investors seeking high rental returns.
  • Requires higher minimum block size and more complex approvals.

Dual Occupancy (Duplex)

  • Two dwellings on one block (attached or detached).
  • Simpler approvals, smaller land requirement.
  • Often used by homeowners for investment or multi‑generational living.
