Who runs my build day-to-day at ResiCorp?

Hamzeh El Sayed, the licensed builder and director, personally manages every ResiCorp project. There are no subcontracted project managers — the licensed builder is on site, every day.

How much does a knock down rebuild cost in Sydney?

A knock down rebuild in Sydney typically starts from $950,000 for a standard 4-bedroom home, including demolition and all associated costs. Site conditions, council requirements and finishes affect the final figure. ResiCorp provides a detailed fixed-price estimate after an on-site consultation.

Do I need to have plans or a DA before contacting ResiCorp?

Not at all. ResiCorp can work from your ideas, from sketch plans, or from full DA-approved drawings. We also provide design assistance if you need help getting started.

How long does a knock down rebuild or duplex take in Sydney?

Most knock down rebuilds run 10–14 months from DA approval to handover. A duplex is typically similar. ResiCorp provides a clear, week-by-week schedule before starting and updates clients throughout the build.

What areas of Sydney does ResiCorp build in?

ResiCorp builds across all of Greater Sydney, including Western Sydney, South-West Sydney, the Hills District, Inner West and beyond. Recent projects include Revesby, Panania, Edmondson Park, Gregory Hills, Wollongong and Austral.

Why most builds go wrong

You've heard the horror stories.

Blown budgets, builders who vanish, and a "project manager" you've never met making decisions about your home. Building shouldn't feel like a gamble.

The budget creeps

Vague quotes become endless "variations" until the final cost looks nothing like the number you agreed to.

Nobody's accountable

Your build gets handed to a subcontracted project manager. The person you trusted is nowhere on site.

You're left in the dark

Calls go unanswered, timelines slip, and you find out about problems long after they happen.

What We Build

Six ways we build across Sydney.

From a single custom home to a full residential development — the complete range of residential construction, every project personally managed by the licensed builder.

Bespoke new homes built to your brief, your block and your budget — or to plans you already have.

The Fixed-Price Promise

The price we agree is the price you pay. Every inclusion is detailed in writing before work begins — no creeping variations, no surprises at handover.

The Builder-Led Promise

Your project is personally managed by the licensed builder from first sketch to handover — never handed to a subcontracted PM.

Knock Down Rebuild

Good to Know

Your questions, answered.

How do I know my budget won't blow out?

Every ResiCorp project starts with a detailed, itemised fixed-price contract — signed before a single nail goes in. Every inclusion is in writing. If something isn't in the contract, we don't charge for it. What we quote is what you pay.

Who actually runs my build day-to-day?

Hamzeh El Sayed — the licensed builder — personally. Not a site supervisor you've never met, not a subcontracted project manager. You get his direct number on day one, and he's on site throughout. That's the ResiCorp difference.

We've had bad experiences with builders before. Why would ResiCorp be different?

Most bad experiences come from builders who over-promise, then hand the job to someone else. At ResiCorp, the person you meet and trust is the person building your home. We also won't take on more projects than we can manage — so you always get our full attention.

What does the free consultation actually involve?

It's a genuine working session — not a sales pitch. Hamzeh visits your site, assesses what's possible, and gives you a clear, honest picture of timeline and budget. You walk away with real information whether you build with us or not. There's no cost and no obligation.

Do I need to have plans or a DA already?

Not at all. We can work from your ideas, from sketch plans, or from full DA-approved drawings. If you already have an architect, we're happy to work alongside them. We also provide design assistance if you need help getting started.

How long does a knock down rebuild or duplex typically take?

It depends on the scope, approvals path and site conditions — but most KDRs run 10–14 months from DA approval to handover. A duplex is typically similar. We give you a clear, week-by-week schedule before we start, and update you throughout.

What areas of Sydney do you build in?

All of Greater Sydney — including Western Sydney, South-West, the Hills District, Inner West and beyond. Not sure if we cover your area? Call or WhatsApp Hamzeh directly on 0423 496 726.
