Pilot Case Study — One Group · Saavira

From Drawings
to Decisions.

Propall takes the architectural drawings you already have and turns them into a complete, interactive, VR-ready experience a buyer can open on any device — long before the building exists.

SHT 01Why this matters

Homebuyers decide with their eyes. Yet most projects are still sold on 2D floor plans, static brochures and a show flat that may not even match the unit on offer.

Site visits are limited, NRI and out-of-city buyers cannot walk the home at all, and the gap between what a developer builds and what a buyer can picture slows the sale and invites cancellations. Propall closes that gap — we turn the drawings you already have into an experience buyers can explore before the first brick is laid.

SHT 03The inputs — drawing set received

The exact files One Group sent us. Nothing more.

Standard architectural drawings — two typical floor plans and two elevation sheets — became the raw material for the entire interactive experience.

SHT 04The output — live walkthrough

From flat drawings to a home you can walk.

A photorealistic exterior render and a fully interactive walkthrough — both produced from the same drawing set, in the same two days.

SHT 06VR-ready, on your own brand

Out of the box. Built into your website.

01

VR-compatible by default

The same link works on mobile, tablet, desktop and VR headsets — no app, no plugin, no download.

02

Embeds into your site

Every output drops straight into your project website or microsite. The experience lives on your brand, not a third-party app.

03

Analytics, your way

Measure dwell time, most-viewed units and drop-off through your own Google Analytics — or let us provide it.

SHT 07Going further

Interactive exteriors, every angle

Buyers orbit the building and study massing, facade, orientation and surroundings before they ever visit the site — the difference between handing over a photograph and handing over the building itself.

Let buyers customise their home

Inside the same walkthrough, buyers choose finishes and upgrades — flooring, kitchen, bathroom, wardrobes, smart-home — and see changes in real time. They submit digitally; the platform produces a cart summary, a branded PDF, and alerts your sales team automatically. A premium experience and a structured upsell engine in one.

SHT 08Why this matters for CREDAI members

Built for how you sell.

Faster sales cycles

Buyers who can see and feel the home commit faster, with fewer cancellations.

NRI and out-of-city buyers experience the full home from anywhere — same link.

Use what you have

We work from your existing drawings — no special inputs needed.
