The problem we solve

Most emerging developers get burned. Not our clients.

If you've been quoted conflicting advice, handed a "free feasibility" that didn't account for contributions and finance costs, or lost weeks to a DA that was never going to get approved — you're not alone.

The Western Sydney development consulting market is full of operators who make money when you build, not when you profit. Altyra was built to fix that. We're an independent pre-construction consultancy — no building arm, no design studio, no kickbacks. Just real numbers, in writing, on time.

Four ways we work with you.

What we do

01 / Service

Feasibility & Site Analysis

$1,500 · 48-hour turnaround

02 / Service

DA Management

Fixed-fee · weekly updates

Full coordination from concept design through to DA lodgement and determination. We engage and manage your architect, town planner, surveyor and engineering team — fixed fee, no hourly billing.

Talk through your DA

03 / Service

CDC Fast Track

20–30 business days

Where your site qualifies for complying development, we secure a certificate via a private certifier in 20–30 business days. CDC eligibility is assessed in every feasibility — so you never commit to a pathway blind.

Manor House CDC

Every engagement is scoped, fixed-fee, and delivered with a weekly Loom update. No hourly billing. No silence. No surprises.

04 / Service

Pre-Construction Management

Approval to slab-pour

From DA or CDC issue through to slab pour. We manage builder tendering, contract negotiation, Construction Certificate coordination and handover to site — so you don't fall through the cracks.

Project types

Every typology. One team.

From single-lot duplexes through to apartments, NDIS specialist housing and subdivisions. No project is too straightforward or too complex.

Modern two-story house with white exterior walls, large glass windows, and wooden accents, surrounded by greenery and trees.

A modern, single-story house with a stone and stucco exterior, large windows, a two-car garage, and a well-manicured lawn at dusk.

Four-unit LMR Stage 2 typology. We've been across this reform since day one and know how to get them over the line.

Manor House (3–4 Dwellings)

Modern row of townhouses with large windows, small front gardens, and a sidewalk in front, trees on both sides, during dusk.

Terrace and townhouse configurations under R2/R3 zoning. Ideal for larger lots with LMR or standard multi-dwelling entitlement.

Townhouse & Multi-Dwelling

Modern multi-story residential building with large glass windows, balconies, and landscaped surroundings at sunset.

Medium-density apartment projects requiring full architectural, traffic, acoustic and ESD coordination on R3/R4 sites.

Residential Flat Buildings

Modern single-story house with a black metal roof, white walls, large windows, and a wooden accent panel at the entrance, surrounded by landscaped garden lights and greenery during dusk.

NDIS / Specialist Disability Accommodation

High-margin, high-compliance typology. We coordinate SDA design standards, participant registration and provider relationships.

An aerial view of a suburban neighborhood under construction with empty lots, paved roads, and new houses.

Torrens, community title and boundary adjustments. We manage surveyor, engineering, council works and registration.

Subdivisions

LMR Stage 2 · Live check

Find out if your block qualifies in 30 seconds.

Since February 2025, thousands of Western Sydney blocks that were limited to a single dwelling can now accommodate up to four — if they sit within 800m of an eligible station. Most landowners don't know it applies to them. Run a quick check below.

For a written eligibility & full feasibility, see LMR Stage 2 Feasibility — Cumberland

This is a guide only — final eligibility depends on flood, heritage, frontage and overlay checks confirmed in the 48-hour report.

Disclaimer This calculator provides indicative estimates only and is intended as a preliminary guide to understanding development feasibility. Altyra Group does not represent or warrant the accuracy of any figures generated, and accepts no liability for any investment or development decisions made in reliance on these outputs. All results are approximations based solely on the inputs you have provided and general market assumptions — they are not a substitute for a full, site-specific feasibility assessment. Before making any investment decision you should obtain independent professional advice from a qualified financial adviser, solicitor, town planner, and valuer. Finance costs are estimated as follows: Land holding interest is applied over the full approval period, plus the construction period, plus two-thirds of the sales period. Construction finance interest is applied over 50% of the construction period plus 40% of the sales period, reflecting a progressive drawdown of construction funds. Stamp duty is estimated using NSW 2025 general (investor) transfer duty rates and may differ from your actual liability.

• What makes Altyra different

Independent. Transparent. Fixed fee.

The most valuable thing a pre-construction consultant can do is tell you not to proceed with a project that doesn't make financial sense. We'd rather lose a client to honesty than lose a client's capital to optimism.

01 / Principle

No builder on our payroll

The most valuable thing a pre-construction consultant can do is tell you not to proceed with a project that doesn't make financial sense. We'd rather lose a client to honesty than lose a client's capital to optimism.

02 / Principle

Fixed fees. No hourly billing.

Every engagement is scoped and priced upfront. Clients know exactly what they're paying before they sign — and never receive a variation invoice for work that was always part of the project.

03 / Principle

Plain English, every step

A weekly Loom video on every active engagement explaining where things are, what's next, and what we need from you. No technical jargon, no radio silence.

04 / Principle

We say no when we need to

If a project doesn't stack up, we say so — even when it loses us the engagement. Real numbers, real advocacy, real accountability.

What developers say

In their own words.

A small selection of feedback from landowners, investors and emerging developers we've worked with across Western Sydney.

"Patrick told us the first block didn't stack up. Saved us $400k in lost capital. The second one he ran did — and we're now under construction."


R. Saunders

First-time duplex investor · Quakers Hill

"They knew the LMR Stage 2 reform inside out before most of the planners we'd spoken to had read it. Manor house DA was issued on the timeline they quoted."


Multi-site developer · Cumberland LGA

A. Mehta

"Fixed fee, weekly Loom updates, no surprise invoices. After two bad experiences with design-and-build firms, Altyra felt like a different industry."


J. Liang

First-time duplex investor · Quakers Hill

"The feasibility report is the document our private lender now asks for first. That alone is worth the $1,500."


D. Nguyen

SDA developer · Blacktown LGA

Frequently asked

Common questions from landowners.

Short answers to the things developers ask first. The full picture lives in the feasibility report — every block is its own conversation.

  • A written report covering: LMR & CDC eligibility, yield scenarios, indicative GRV based on current comparable sales, fully itemised TDC (build, fees, contributions, finance, contingency), residual land value, and a pathway recommendation (DA or CDC) with reasoning. Plus a 15-minute walkthrough call with Patrick. Turnaround is 48 hours from payment.


  • Often. The most valuable thing a pre-construction consultant can do is tell you not to proceed with a project that doesn't make financial sense. We'd rather lose a client to honesty than build a relationship on a deal that costs them money — and our fee is paid either way, so we have no incentive to push a borderline site through.

  • A complying development certificate via a private certifier should issue in 20–30 business days. A full council DA for a duplex in Blacktown LGA currently runs ~128 days median; manor houses can be 90–150+ days. CDC requires strict compliance with all SEPP controls — if your design needs any variation, you'll need a DA. We assess both pathways in the feasibility.

  • No preferred builders, no kickbacks, no referral fees — that's the entire point of how we operate. We do maintain working relationships with around six competing duplex/manor house builders across Western Sydney so we can run competitive tender pricing for your project. You choose, on the numbers.

  • Those are our primary LGAs. We do work on sites all around Sydney — on a case-by-case basis when the site warrants the deeper local research.


  • Standard duplex, dual occupancy, townhouse and other DA pathways may still apply under the existing LEP controls. The feasibility covers all available pathways, not just the LMR scenario — so you finish with the best route, not just the trendy one.
