What to send a rendering studio so the first draft is close

Most render projects that run late did not run late because of the rendering. They ran late because the brief was thin, the first draft missed, and two rounds were spent discovering what the client actually wanted.

Here is what to send so that does not happen.

The minimum to get started

This is what studios mean by a rendering brief: the files and decisions a studio needs before it can quote and model. You can begin with less than people assume:

• Elevations — all four
• A floor plan — at least the level being shown
• One sentence on what the image is for

That last one is doing more work than the drawings. “For our DA” and “for the sales campaign launching in March” produce completely different images at completely different prices, and a studio that does not ask which one you need is not paying attention.

Missing some drawings? That is normal — here is what a studio has to assume without them, and how to keep those assumptions out of the final image.

What makes the first draft genuinely close

A site plan with a north point. Without it, sun angles are guesswork. With it, the light in your render is the light your building will actually get — which matters when a client asks whether the courtyard gets afternoon sun.

A finishes schedule. Named products, not “dark brick”. Studios who hold scanned material libraries can match a specified range exactly; nobody can match a description.

Site photography. Four phone photos from the street corners. It tells the studio what is actually around the building — the neighbour’s ugly carport, the mature tree worth keeping in frame, the slope nobody drew.

Two or three reference images. Not of buildings you like — of images you like. “This mood, this time of day, this level of styling.” Thirty seconds of effort that removes an entire revision round.

In NSW, add the BASIX certificate

A new home in New South Wales, or a renovation of $50,000 or more, needs a BASIX certificate, lodged with the development application or complying development certificate. The certificate lists the design’s sustainability commitments, and the assessment behind it uses details such as the size, location and type of the windows.

That makes it a useful cross-check on the drawings. If a render shows windows that differ from the ones the BASIX assessment used, one of the two is out of date, so send the certificate with the brief and say which is current.

The single most valuable thing you can provide

Say where the image will be used and at what size.

A hoarding at three metres wide, an A4 brochure, an Instagram post and a planning PDF are four different jobs with four different resolutions, crops and levels of detail. Studios quote for the one they assume, and assumptions are where budgets go wrong. Our guide to render resolution has the sizes for each.

What slows a project down

Drip-fed information. Sending elevations now and the finishes schedule after the grey-box is approved means the materials pass starts late and the deadline moves.

Unconsolidated feedback. Four emails from four people across three days, sometimes contradicting each other. Collect internal comments, resolve the disagreements internally, then send one list. Every studio prices for consolidated feedback and absorbs the cost of the other kind — until it happens twice.

Design changes after grey-box approval. Fine, and normal — just expect a re-quote. If you know a change is coming, say so before the materials pass rather than after.

For typical turnarounds once the brief is complete, see how long 3D rendering takes.

A 3D rendering brief template you can paste into an email

□ Elevations (all four)
□ Floor plan(s) for the levels shown
□ Site plan with north point
□ Finishes schedule — named products
□ 3–4 site photographs
□ 2–3 reference images for mood and styling
□ What the image is for, and at what size
□ Deadline, and whether it is real or aspirational
□ Who gives final approval

That last line prevents more delay than all the others combined.

Prefer paper? The printable briefing checklist is the same list as a one-page form, with room for the project details.

What you should get back

Within two business hours: a fixed price, a written scope, and a delivery date. If what comes back is a range, an hourly rate, or a request for a call before any numbers, you are at the beginning of a sales process rather than a project.
