Your physical sales gallery opens for a few hours a day, in one city, to whoever can travel to it. Most of the people who will buy your project are not in that room. Some of them are in another country, and some of them are deciding at eleven at night.
An online property sales gallery is that same sales conversation without those limits: the development laid out as something a buyer can explore, down to a floor and a single unit, showing what is actually still available.
This guide covers how one gets built. What you supply, how the journey is structured, how availability connects, where it gets published, and what reaches you afterwards.
What an online property sales gallery is
Worth being precise, because the term gets used for very different things.
It is not a brochure site, a 360 tour, or a page of renders. It is a connected path with inventory behind it:
- The master plan as the entry point, zoomable to whatever detail your artwork holds
- Precincts, towers or clusters the buyer opens from that plan
- Floors, with units drawn on the floor plate
- A unit, with its layout, size, orientation, current status and an enquiry attached to it
The last point is the one that separates a sales gallery from a marketing asset. A brochure shows what was available the day it went to print. An online sales gallery connected to your inventory shows what is available now.
Step 1: Prepare your visual assets
The foundation of a digital sales experience is the visual assets you already produce for marketing:
- Site plan render — high-resolution PNG or JPEG of the master plan layout
- Building images — exterior views, orientation views, or 360° panoramas
- Floor plan drawings — per-floor unit layouts, separated by unit type rather than merged onto one sheet
- SVG overlays (optional) — architectural drawings with unit boundaries for precise interactive zones
- Marketing imagery — lifestyle renders, amenity visuals, and project photography
Most of these assets exist in your marketing pipeline. The key is to collect them in high resolution (at least 4000px wide for site plans).
Hand over the originals rather than the compressed copies that went to the website. The master plan becomes deep-zoom tiles, so its pixel width decides how far a buyer can zoom before the image softens.
Two non-visual items belong in the same handover:
- The unit list: unit code, type, bedrooms, size, floor, orientation, status, and price where you intend to show it.
- One agreed unit code. If the floor plan, the price list and the sales system each name the same unit differently, every one of those has to be reconciled before availability can connect to anything on screen.
Agree the unit code before you start and you remove the single most common cause of delay.
Step 2: Structure your view hierarchy
Before building the interactive experience, define the navigation structure:
- Site plan — the top-level entry point showing the full development
- Precincts or clusters — groups of buildings or zones within the master plan
- Buildings — individual tower, block, or villa cluster views
- Floors — per-level floor plans with unit layouts
- Units — individual unit detail with type, size, availability, and enquiry CTA
This hierarchy becomes the buyer's navigation path. Not every project needs all levels. A single tower might go directly from building view to floor to unit, and a land subdivision might go from the master plan straight to a plot.
Step 3: Build the interactive experience
Your files become the interactive surface directly. The master plan you paid for stays the master plan buyers see.
The development is mapped onto that artwork: zones drawn over the plan, buildings made selectable, floors connected to each building, units drawn on each floor plate. What was one flat image becomes a path a buyer can walk. Amenity markers, labels, 360 views and floor-plan PDFs attach where they belong.
Most projects are built in 2D, and that is not the lesser option. 2D is the mature surface, carrying unit filtering, the floor selector and floor stack, the labels layer, amenity markers, 360 views and attached PDFs. It handles very large sites and many phases comfortably, and it runs on any phone. Where a 3D model exists, a building can be explored as a model instead, turned so a buyer sees which units face which way. See 2D vs 3D for property sales for how that choice is usually made.
The project is built with you from the material you supply, rather than handed over as an editor and a manual.
Step 4: Connect live availability
This is the step that separates an online sales gallery from an expensive picture.
Your unit schedule drives what buyers see. Units carry five states:
| Status | What it means on screen |
|---|---|
available | Open for sale and enquiry |
reserved | Held against a booking |
sold | Closed |
held | Withheld from sale for your own reasons |
unreleased | Visible as part of the project, not yet on sale |
unreleased matters more than it sounds. It lets you publish a whole phase while still deciding what to put on the market, so buyers can explore the development in full before anything in it is sellable.
When your team marks a unit reserved, it shows as reserved on the plan, in the building, on the floor plate and in the filter, everywhere that project appears, without anyone republishing anything.
Buyers narrow the project themselves by status, bedrooms, tower, floor, type, orientation and price, and can put two units side by side to compare. Forty units become three, which is usually the moment a buyer stops considering and starts choosing.
Step 5: Configure lead capture
Every interaction point is a potential lead capture moment:
- Unit-level enquiry — buyer submits interest from a specific unit
- Callback request — buyer asks for a call while exploring a floor plan
- WhatsApp link — pre-filled with the unit and building context
- Brochure download — gated behind a lightweight contact form
What arrives is the part most developers underestimate. Each lead carries the unit, the project, the view the buyer was on, the action they took, and the journey across that visit: which zones they opened, which units they looked at, what they shared.
Your team opens the first call knowing the buyer was on level 18 of the east tower comparing two three-bedroom units, instead of opening with "how can I help". Why buyer context beats a basic contact form covers what that changes in follow-up.
Give each salesperson and each agency agent their own link to the project, and the enquiries arriving through it are credited to them automatically.
Step 6: Publish and place it
A built project is published once, then placed. Each placement is a way in rather than another copy to maintain:
- Its own link for campaigns, emails, WhatsApp, and QR codes on hoardings or brochures
- Embedded in your website, so buyers explore without leaving your domain
- Embedded in your agencies' websites, restricted to the domains you approve
- Full screen on the sales gallery display, running in a browser on the screen in the room
The website embed is a script tag carrying a placement ID, not an iframe, and each placement is tied to the domains you allow. An embed cannot be lifted onto a site you never agreed to, and each one carries its own identity, so an enquiry tells you which placement produced it.
One limit is worth planning around: the simplest script-tag embed does not carry 3D scenes or the geographic portfolio map. Those need the module-based embed or the project's own link. If a project leads with either, decide placement before launch rather than discovering it afterwards.
Availability, enquiry routing and configuration update without republishing the project. How placements work goes through the lifecycle in detail.
Step 7: Monitor and optimize
After launch, track buyer behavior:
- Which zones and buildings attract the most views
- Which floors and unit types generate the most interest
- Where buyers drop off in the navigation journey
- Which lead capture CTAs convert best
- Which marketing channels drive the most engaged visitors
That is a different question from which parts you promoted, and the answer is occasionally uncomfortable. A tower you treated as secondary drawing the most attention is information you can act on, in pricing, in release order, and in where the campaign budget goes next.
Timeline
The steps of a typical digital launch:
| Phase | What happens |
|---|---|
| Asset collection | Gather site plan, floor plans, building images, unit list |
| Unit code reconciliation | Agree one code across floor plans, price list and sales system |
| View building | Upload, configure hotspots, link views |
| Review and publish | Internal review, go live |
| Lead monitoring | Track engagement and follow up |
How long each step takes depends on the material and the size of the project.
The bottleneck is almost always asset collection and unit codes, not platform setup.
What an online sales gallery does not do
Stating the boundary is more useful than another benefit:
- There is no kiosk build and nothing to install. The gallery screen runs the same responsive web project as your website, which is precisely why it never drifts out of step with it. It does need a connection, so an unreliable gallery link is worth fixing before launch.
- Availability is only as current as your team makes it. The platform reflects your inventory immediately; it does not know a unit was reserved until someone records it.
- Unit filtering applies to 2D scenes. A 3D building carries selection, status and enquiry, not the full filter set.
- It does not calculate commission or push leads into a CRM. It records who brought an enquiry and holds that on the lead, which is the part that actually gets disputed. The commercial terms stay in your agreements.
Getting started
The starting point is what you already have: visual assets from your marketing and design teams, and a unit list from sales. A digital sales center platform turns these into interactive buyer experiences, without 3D models, custom development, or months of setup.
The first useful conversation is usually about your unit list, not your renders.
