A genuinely accurate quote takes time. For a typical renovation or extension we're looking at multiple site visits, detailed measure-ups, scope documents, trade pricing, allowances, inclusions, and a programme of works. That's not a one-hour exercise.

"Free quotes" exist, but someone is always paying for them. Usually it's the next ten clients who get vague pricing built on assumptions. The risk is that variations creep in once construction starts — costs blow out, scope gets renegotiated, and the relationship sours.

By charging a pre-construction fee, we can spend the time properly investigating your project. We pull apart the drawings, walk the site, talk to the right trades, and produce a quote you can actually rely on. If you proceed to construction, the work done in pre-construction directly informs the build — nothing is wasted.

"The cheapest quote at the start is rarely the cheapest project at the end."

— Chris Parry, Director

It's the most common question we get, and the most honest answer is this: every project is different, and a square metre rate hides more than it reveals.

Two 60m² extensions on the same street can vary by hundreds of thousands of dollars depending on:

• Site access — can a truck get in, or is everything carried by hand?
• Existing conditions — heritage features, asbestos, structural issues
• Level of finish — laminate vs stone, builder-grade vs custom joinery
• Roof line, structural complexity, and services relocation
• Whether you're working around an existing house or from a clean slab

A rate is fine for a rough order of magnitude at the very start of a feasibility conversation. But the moment a builder commits to a square metre rate before they've seen your site and your drawings, you should be cautious about what's not being said.

"Two extensions on the same street can vary by hundreds of thousands of dollars. The difference is in the detail."

— Chris Parry, Director

Our renovations, extensions and second storey additions on the Northern Beaches typically sit in the high six figures to mid seven figures. We work best with clients who value finish quality and a clean process over chasing the cheapest possible price.

If your project budget is significantly outside this range, we'll tell you upfront — we'd rather have an honest conversation early than waste your time.

Our fixed-price quote is itemised by trade and stage, so you can see exactly where the money is going. A typical quote includes:

• Detailed scope of works
• Trade-by-trade pricing breakdown
• Schedule of inclusions and exclusions
• Prime Cost (PC) and Provisional Sum (PS) allowances
• Programme of works with key milestones
• Payment schedule tied to construction stages

We don't believe in vague quotes with "allowance for finishes" sitting against a single number. Every item that can be priced firmly is priced firmly. Where we use an allowance, we explain why.

"Every item that can be priced firmly is priced firmly. Where we use an allowance, we explain why."

— From every Formation Building quote

For larger projects, an architect or client may engage a Quantity Surveyor to produce a Bill of Quantities (BoQ). The BoQ itemises every component of the project so all builders tendering are pricing the same scope.

A builder's quote is different. It's our actual price to deliver the project — based on our trades, our overheads, our methodology, and our assessment of project risk. Two builders quoting from the same BoQ will land on different numbers, because the BoQ doesn't price the things that actually matter: how each builder runs a site, the quality of the trades, and the systems behind delivery.

The quality of a quote is directly tied to the quality of the documentation. The more detail we have at the start, the more accurate and reliable the final number will be.

For a precise fixed-price quote, we ideally have:

• A full set of architectural drawings
• Engineering design and structural details
• Soil test report
• Detailed schedule of finishes and fittings
• Survey (Identification and/or Contour & Detail)
• Any council conditions or DA approval documents

If you're earlier in the process — perhaps still working with your architect — we can still help. We'll provide a preliminary estimate based on concept drawings, but it's important to understand it's an estimate, not a fixed price. The accuracy improves as the documentation does.

Yes. We have strong working relationships with several Northern Beaches architects and designers we trust. After our initial discovery call, we can introduce you to people whose style and process suits your project.

There's no kickback or commission — just builders and designers who like working together because it produces better results for clients.

"A good builder and a good architect should make each other's work better — not compete with it."

— Chris Parry, Director

Even in the most detailed quote, there are some things that genuinely can't be priced firmly when the contract is signed — usually because the final selection hasn't been made yet, or because the work involves variables nobody can know in advance. For these, we use two specific allowances.

"Certainty about cost comes from decisions made early — not promises made cheaply."

— Chris Parry, Director

Both PC and PS allowances are adjustments to the contract — not variations. The contract price moves up or down based on the actual cost compared to the allowance.

If the actual cost comes in under the allowance, you get the saving. If it comes in over, the difference is added (along with the builder's agreed margin on the overage).

This system is designed to share risk fairly. The builder isn't carrying every unknown, and you're not paying inflated contingencies on things that turn out to be straightforward.

The aim during pre-construction is simple: turn as many allowances into firm prices as possible before the contract is signed. The more decisions you make early, the more certainty you have about the final number.

A variation is a change to the agreed scope after the contract is signed — usually because the client wants to add, remove, or change something.

Our process is straightforward: every variation is documented in writing with a clear price, scope, and any impact on the programme. Nothing changes on site without your written approval first. This protects both of us — there are no surprises at the end of the job, and no debates about who agreed to what.

The best way to minimise variations? Spend time in pre-construction making decisions before construction starts. The clients with the smoothest builds are the ones who walked into construction with their selections already locked in.

"Nothing changes on site without your written approval first. No surprises at the end. No debates about who agreed to what."

An Identification Survey (or "Ident") is carried out by a registered surveyor to confirm exactly where existing buildings, fences and improvements sit on a parcel of land — and whether anything encroaches across boundaries.

It's typically obtained when buying property (your solicitor usually arranges one), but it's also valuable before any significant renovation or extension. It tells us — and you — exactly what we're working with.

Without one, you're risking an expensive surprise if a fence, eave or structure turns out to be in the wrong place.

A Contour and Detail Survey (sometimes called a topographic survey) records the levels, contours and physical features of your site. It's almost always required by your architect and engineer — they need it to design properly.

It typically captures:

• Site levels and contours
• Boundary positions
• Existing buildings and floor levels
• Significant trees and vegetation
• Visible services
• Adjoining ground levels

The soil under your house determines how the foundations are designed. Soils on the Northern Beaches vary considerably — from sandy coastal sites to reactive clays further inland.

A geotechnical report classifies your site, which directly affects the slab and footing design. Skipping it means designing footings on assumptions — a fast way to overspend or under-engineer the foundations.

"The work you can't see — surveys, soil tests, services — is where most projects quietly succeed or fail."

— Chris Parry, Director

Most renovations and extensions on the Northern Beaches require either a Development Application (DA) through Northern Beaches Council, or a Complying Development Certificate (CDC) through a private certifier. Which path applies depends on the scope of work, your zoning, and any site constraints.

Your architect or designer will usually manage the lodgement, but we work alongside them to make sure the design aligns with what's actually buildable.

Before any design starts, it's worth understanding what your land allows. Common constraints we check for early:

• Zoning and floor space ratio (FSR) limits
• Heritage listings or conservation area controls
• Bushfire-prone land classifications
• Flood-prone or overland flow path mapping
• Protected vegetation and tree preservation orders
• Coastal erosion or stormwater overlays
• Existing easements (drainage, sewer, access)

Catching any of these early can save tens of thousands of dollars in redesign work later.

"The best time to find a problem with your land is before the architect starts drawing — not after."

— Chris Parry, Director

It varies enormously by scope, but here's a realistic guide for projects we typically take on:

"Realistic timeframes, not best-case fantasies. The job takes as long as it takes — done properly."

— Chris Parry, Director

For a partial extension, sometimes. For a whole-house renovation or second storey addition, usually not — at least not for the bulk of the build.

We'll have an honest conversation about this in pre-construction. Some clients underestimate how disruptive an active building site is to live in, and we'd rather flag it early than have you regret it three months in.

We deliberately keep our active project count small. Formation Building is Chris and a small team of site supervisors — a structure built on purpose, not a limitation we're working around.

Choosing a smaller, boutique builder over a large-volume operation means:

• Director-led delivery. Chris is personally across every project from discovery to handover — not a salesperson at the start and a project manager you've never met running the build.
• Direct access. When you need a decision, you call Chris. No layers of admin staff, no waiting for someone to "check with the boss."
• Better trades. Our trades aren't being spread across ten sites at once. They're on yours when they should be, doing work to the standard we've agreed on.
• Higher attention to detail. A small project load means more time per build. The finish, the joinery, the things you'll see every day — they get the time they deserve.
• Cleaner communication. Your emails get answered the same day. Your site meetings happen on time. Nothing falls through the cracks.
• Long-term accountability. Our reputation is built one project at a time — which means we have skin in the game on yours.

"Doing fewer projects, better — that's the whole idea."

— Chris Parry, Director
