A render can look right and still fail once someone leans back, drags a chair across a floor, or leaves a table in a dry winter and a damp summer. A buyer signs off because the next step costs real money, so the decision needs more than a picture. This product design proposal frames the work as a production-ready furniture package, with the wording already there for buildability, durability, and repeatable manufacture.

The document starts with the production-ready furniture package and a plain-language summary of what gets designed, proven, and handed over. The middle pages cover who’s doing the work, the team, and recent examples, then move into the core deliverables, from the brief and measure record through to prototype findings, drawings, and cut lists, so the client reads the decisions before they reach the price. The pricing section names Prototype Proof as the option being accepted, and the later pages answer the questions that usually stall approval, like materials sourcing, who builds, lead times, and seasonal movement.

  • Summary Explains the production-ready furniture package, from concept through sign-off, in the order a buyer needs to understand it.
  • Brief and measure record Captures the agreed constraints and key dimensions, so the work stays anchored once CAD and prototyping start.
  • Prototype and test findings Documents what the prototype revealed and what changes carry into the final drawings and finish decisions.
  • Pricing Prices Prototype Proof as the item the client accepts, leaving you to replace the template numbers with your own.
  • Next steps Holds the signature and fee summary, plus the practical questions that come up right before approval.

Once the proposal is in your workspace, you replace your prices for the one item, send it, and the client accepts and signs online. The signed copy and the fee summary land back on the proposal, so everyone has the same scope, terms, and sign-off point to work from.

We went from spending hours on every proposal to creating fully customized ones in under 5 minutes. That's not an exaggeration - we timed it.

What to include in a product design proposal

PartWhat it covers

St Clair Works PRODUCTION-READY FURNITURE PACKAGE

Opens the proposal as a production-ready furniture package, so the client knows they’re approving buildable pieces rather than a concept render.

Summary

States the outcome, the stages from design through prototype and drawings, and what the proposal covers before the client reaches pricing.

Who you are working with

Explains how the work stays grounded in dimensions, tolerances, materials, and workshop decisions, which is what a buyer needs to trust the handoff.

The team

Names that the same four people carry the work through, so decisions stay connected from first measure to sign-off.

Recent projects

Introduces the example work that follows, so a client can judge the kind of packages and outcomes you produce.

Narrow-site banquette

Describes an example focused on tight clearances and a prototype that confirmed the fit and details that take wear.

Stackable café chair

Describes an example focused on repeatable joinery and a finish schedule, with drawings a maker can quote without padding the price.

Retail display plinth set

Shows an example focused on modular build and tidy edge details, including a short client quote about the prototype and drawings matching the build.

Brief and measure record

Covers the constraints, key site dimensions, and early decisions, because those don’t survive a project unless someone writes them down.

Prototype and test findings

Covers what gets built and tested and what changes as a result, then moves into the drawing set, cut lists, and finish spec a builder can follow.

Pricing

Holds a priced items table with Prototype Proof, so you update the numbers and the client accepts the option shown.

Next steps

Carries the signature and fee summary, plus the steps and practical questions that come up at approval, so the client can sign without a back-and-forth email thread.

What’s the lead time if we need it installed before opening?

Answers the lead-time question in plain terms and ties timing to piece count, complexity, and who builds, so expectations stay realistic.

Payment

States the payment stages, invoicing due dates, how changes get priced, what access and info you need to start CAD, and how prototype costs get billed.

Lead times

Explains how scheduling gets confirmed, what can move dates, how builders and suppliers get named, what first-article sign-off means, and when ownership transfers.

Who it is for

Furniture designers, industrial and product design studios, and fit-out teams quoting production-ready seating, tables, banquettes, or retail fixtures for hospitality and consumer products.

St Clair Works

PRODUCTION-READY FURNITURE PACKAGE PROPOSAL

Summary

You’ll have furniture that fits the plan, doesn’t rock or rack, and can be built again to the same dimensions, finish, and feel, with drawings a workshop can price with confidence.

We’ll design the pieces, build and test a prototype, then hand over drawings your joiner or factory can quote and build without guesswork. This proposal covers the production-ready furniture package, from concept through sign-off, and what it costs.

We start by measuring and agreeing the constraints that make furniture succeed in the real world, like clearances, stability, joinery, and finish wear. Then we sketch, mock up at scale, model in CAD, and prototype. We only lock the final design once we can build it, sit on it, and repeat it.

Who you are working with

We’re an industrial and furniture design studio that sits close to the bench. We came up through making and detailing, so we don’t stop at a render. Our work lives in dimensions, tolerances, and materials that behave. That is how a chair stays solid, a table stays flat, and a finish stays presentable under daily use.

People come to us when they can’t afford a second build. We make decisions you can point at in a drawing set: fixings, edge details, clearances, and how parts locate during assembly. We’ll show you what changes and why before it hits the workshop. You get a package that a joiner can quote, build, and repeat.

The team

You’ll deal with the same four people through the job, so decisions stay connected from first measure through to first-article sign-off.

Recent projects

A few recent packages that went from concept to build, with prototypes and drawing sets that workshops could quote and repeat.

Narrow-site banquette

Designed a banquette and two-top system to keep a tight aisle clear. The prototype confirmed seat height, kick space, and a base detail that cleaners could get around without damage.

Stackable café chair

Turned a sketch into a production chair with repeatable joinery and a durable finish schedule. The final drawings let a small maker quote parts and labour without adding contingency.

Retail display plinth set

Built a modular set that packed flat and assembled quickly. The cut lists and hardware callouts reduced on-site fiddling, and the edge details stayed tidy after frequent moves.

“We were worried the prototype would reveal problems we couldn’t fix in time. Instead it made the build straightforward, and the drawings matched what arrived.”

Cafe owner, a long, narrow fit-out

Brief and measure record

A written summary of the constraints we agreed, key dimensions from site measure, and the decisions that affect fit and flow, so the work stays anchored as it moves forward.

CONCEPT SET

A small set of sketches and layout options that show seating count, clearances, and overall proportions, with one direction chosen before we invest time in detailed CAD.

SCALE MOCK-UP NOTES

Photos and measured notes from a quick mock-up of the critical parts, like seat height, table spacing, and edge overhangs, so comfort and access are decided early.

Prototype and test findings

One built prototype or a representative prototype section, plus what we learned from wobble, racking, fasteners, and finish touch points, with clear changes carried into final detailing.

PRODUCTION CAD AND DRAWINGS

A complete drawing set suitable for quoting and manufacture, with dimensions, joinery details, hardware callouts, and tolerances shown where they control fit, stability, and repeatability.

CUT LISTS AND FINISH SPEC

Cut lists and a material and finish schedule that names timber species, sheet goods, adhesives, upholstery and foam where used, plus the finish system and sheen so the look can be repeated.

Pricing

Pick the tier that matches how far you need us to take it: drawings only, prototype proof, or a small-batch run with first-article sign-off.

Priced items

Next steps

If the scope and price below look right, we can book the measure and brief session and start turning the layout into buildable pieces.

1. Sign the proposal and choose the pricing option. 2. Send any plans, a rough layout, and the opening or delivery date. 3. Book the site measure and brief workshop with us.

CAN YOU WORK WITH LOCAL TIMBERS AND WOOL UPHOLSTERY, OR IS IT ALL IMPORTED?

We can specify local timbers and wool upholstery where they suit the job. We’ll also call out moisture movement, lead times, and finish systems that work with those materials, so the choice is practical as well as good-looking.

WHO ACTUALLY BUILDS IT: YOUR SHOP, A LOCAL JOINER, OR OFFSHORE?

Any of the above. This package is written so a local joiner, our workshop, or an offshore factory can build it. If you already have a builder, we’ll format the handover around how they quote and work.

Signature

Fee summary

What’s the lead time if we need it installed before opening?

We’ll confirm the timeline when we know the piece count and complexity, plus who is building. As a guide, concept and detailing move faster than manufacturing. If the opening date is fixed, we’ll plan backwards from it.

HOW WILL THIS HOLD UP TO OTAGO HUMIDITY AND HEATER-DRY WINTERS?

We design for movement and wear: timber selection, grain direction, joinery that allows seasonal change, and finishes that can be maintained. We’ll also flag where solid timber is the wrong call and suggest stable alternatives.

Payment

We invoice 40% to book the project, 40% when the concept set is approved, and 20% on delivery of the production CAD and drawings. Invoices are due within 7 days.

Changes. We price the scope above. If the brief changes after concept approval, we’ll write up the change, the added fee, and any timing impact before we do the extra work.

What we need. We need access for site measure, plus any available lease plans, services locations, and appliance specs before we start CAD. We also need a decision-maker for sign-off within 3 working days.

Prototype costs. Prototype materials and any outsourced processes are billed at cost with receipts. We’ll confirm the expected spend before we order anything, and we won’t proceed without your written approval.

Lead times

We’ll give a schedule after the brief and measure workshop. Dates move if approvals, supplier information, or site access move. We can’t hold installation dates until drawings are signed off.

Suppliers and builders. We can work with your joiner, a local shop, or our own workshop where it suits the job. We’ll name who is building what before prototype or production starts, so pricing and responsibility stay clear.

Factory liaison. Factory liaison and first-article sign-off mean we check the first unit against our drawings and finish spec, then issue a punch list. We don’t supervise every unit unless you ask us to.

Ownership. Once paid, you own the finished design outcome and can build from our production drawings for this project. We keep ownership of our CAD files and working methods unless we agree otherwise in writing.

Questions about this proposal template

What should a product design proposal include?

A product design proposal usually covers the scope and deliverables, the handover format, the price, payment terms, and what “sign-off” means. This one also spells out how prototyping, drawings, and finish decisions get documented so a builder can quote and repeat the build.

How do you describe production-ready deliverables for furniture?

Production-ready deliverables read like instructions a workshop can price and build from: drawings with dimensions and tolerances, joinery and hardware callouts, and a cut list and finish spec. This proposal also includes prototype and test findings, so the final detailing reflects what the prototype proved.

Do you need a prototype before releasing drawings?

A prototype helps confirm stability, racking, fasteners, and finish touch points before anyone commits to a batch run. This proposal treats prototyping as part of the package and records what changed as a result, so the drawings reflect what’s been tested.

Can a product design studio specify local timbers and wool upholstery?

A studio can specify local timbers and wool upholstery when those materials suit the use case and lead times. This proposal covers calling out moisture movement and finish systems alongside the material choice, so the spec stays buildable.

Who should build the furniture: the designer, a local joiner, or offshore?

Any of those can work, as long as responsibility and pricing stay clear before prototype or production starts. This proposal addresses that handoff and includes factory liaison and first-article sign-off language for checking the first unit against the drawings and finish spec.

How do you plan furniture design lead times around an opening date?

Lead times depend on complexity, piece count, and who’s building, so the opening date only becomes meaningful once those are known. This proposal covers planning backwards from a fixed date and notes that installation dates can’t be held until drawings are signed off.
