We took a 4BHK floor plan from a developer’s brochure and built the flat four times over: a film, a walkthrough, a 360° VR tour and a VR flat you can walk around. One measured 3D model sits behind all four, so they can’t disagree.
Go on, drag the line and try to catch us out. Every wall in the render sits on its wall in the drawing, because both come from one set of measurements, checked room by room against the plan.

03 / What we do
A floor plan tells a buyer how big a room is. A walkthrough lets them stand in it. We build that from your drawing, check it against every dimension, and send it back as one link that opens on any phone.
Six kinds of client start from the same thing, a floor plan, and each wants something different out of it. Tell us which one is you, and we’ll set up the price calculator below to match.
For developers
Sell the tower before the first slab is poured.
A brochure shows a plan. A buyer wants to stand in the living room. We turn your approved drawings into homes people walk through on their own phone: one sample flat, every layout on a floor, a whole tower, or all the towers and the grounds between them.
Buyers walk the flat on their own phone, at true room sizes, months before possession.
from₹
Seat a family in the living room with a VR headset, or send the same tour as a link.

A short film for Instagram, WhatsApp and the launch screen, ready in days.

The plan rises into the building as the visitor scrolls. One link for the whole launch.

For interior designers
Let your client walk through the design before a single piece is bought.
A mood board asks your client to imagine. A walkthrough lets them see. Work with us and we bring your drawings and material choices to life, so the room you designed is the room they approve, sooner and with fewer changes on site.
Your client moves through the finished room on a phone or laptop and points at what they love.
from₹
Each room in 360° with true depth. Far easier to approve than a flat render.

Turn a finished design into a short film and reels for your own marketing.

For homeowners
Change your mind on screen, not on site.
We build your home on screen first, outside and in: the front from the street, every room, the light at each hour. Moving a wall in a render costs a message. Moving it after construction costs demolition, new material and weeks of delay. See it, change it, then build it.
Every room at its true size, with your finishes, on your own phone.

Look all around in true depth and judge the height, the light and the view.

For architects and builders
Present the building, not just the drawings.
Your client cannot read a section, and should not have to. Give them the building to walk through and the approval comes faster, with the changes made on screen, before the contractor is on site and every change has a bill attached.
Hand the client the building and let them walk it, room by room.

Ceiling heights and room sizes read at once in a 360° view with true depth.

The plan rises into the building as the visitor scrolls: your drawing, doing the selling.

For hosts
Make guests want to book before they finish scrolling.
Guests decide in seconds, from a phone. We make furnished images of rooms that are still empty, short reels cut for Instagram, and a page of your own where guests see the place and book on WhatsApp without a platform fee.
A short film of the place, cut for how guests actually find stays.

A 360° tour of each room, so there are no surprises at check-in.

For investors
Walk the flat from another country before you pay for it.
Buying off-plan or from abroad means deciding on a home you have never stood in. A walkthrough made from the approved floor plan shows you each room, its true size and its light, on your phone, wherever you are.
Look around every room in 360°, on a phone or in a VR headset.

the catalogue
It all happens online. No site visit, no hardware, nothing for your buyers to install. You don’t even have to make us chai.
A PDF, an image or a photo of the brochure page, on WhatsApp or by email, whichever is nearer your thumb. Add finishes or reference photos if you have them.
We model it from the plan and check every room against it. You’ll see previews as we build. On the Flexible plan, ask for changes as often as you like.
Your tour, film or page opens on any phone, laptop or VR headset. Send it on WhatsApp, show it in the sales office, or put it on your site.
For a 2BHK, from the day we have your plan and choices.
A floor plan with room sizes: a PDF, an image, or a clear photo of the brochure page. Tell us the flat type and the format you want. Finish schedules or reference photos help, but we can start without them.
Typically 3–5 working days for an AI film, 7–10 for a 360° tour or a real-time walkthrough, and 10–15 for a walkable VR flat or a scroll landing page, counted from the day we have your plan and choices. Larger flats add a few days. Every quote comes with a delivery date.
From ₹15,000 for an AI film of a 2BHK, up to ₹75,000 for a walkable VR flat or a landing page. A 3BHK adds 25%, a 4BHK 50% and a 5BHK 75%; a villa or house with its exterior is about double. All four flat formats together are ₹1,25,000. Prices exclude GST. The quote builder above gives you a number in seconds.
Yes. For apartments we work at four levels: one apartment, one floor of three or four apartments, one complete tower, or the whole project with every tower, every layout and the grounds between them. For villas and houses there are two: one home, inside and out, or the whole township. As a guide, a floor is about 2.5 times the price of one apartment and a tower about 5 times. A whole project is quoted from its master plan, from about 12 times one apartment; a township from about 8 times one home.
Choose between two plans. Fixed is the listed price: we build to your brief and the work is final on delivery. Flexible costs 40% more and includes unlimited small changes, such as a finish, a colour, a piece of furniture or one room, plus up to five full redesigns. On either plan, anything we got wrong against your plan or brief is corrected free.
We build from the dimensions on your plan and check every room against it by script. On our Sunshine sample the largest difference is 0.04 inch, which is rounding in the plan’s own labels. Anything the plan does not show, such as ceiling height, the view or finishes, is agreed with you and marked as illustrative.
No. Every tour opens from one link in the browser of a phone or laptop. A headset is optional: the same link opens in the browser of a Meta Quest for the full VR version. iPhones and iPads show the on-screen version.
Yes. Send your finish schedule, material photos or reference images and we match them. On the Flexible plan you can keep changing them until they are right. Pages and tours can carry your logo and colours, and designers and brokers can resell them under their own brand.
A hand sketch with measurements is enough to start. Yes, even one on the back of an envelope. For a home that already exists, send phone photos and the main dimensions. We work remotely, so there are no site visits.
You get one link for each tour or page. Send it on WhatsApp, print it as a QR code, or put it on your website. Hosting on our servers is ₹6,000 per tour per year, or we hand over the files for your own team to host. Films are delivered as files and are yours to keep.
Half to start and half on delivery. Prices exclude GST. Our first five clients get 30% off in return for letting us show their project here.
Yes. Everything is made and delivered online, so we work with clients across India and with buyers abroad. The floor plan does the travelling.
