3D models, architectural visualisation and virtual tours for property.
For architects, developers and sales teams we build a project website with an interactive 3D model of the complex and virtual tours of the apartments. In the browser a buyer picks a building and a floor, opens a single unit, sees the floor plan, areas and availability, and walks through the space in real time - on a phone, tablet or desktop, with nothing to install.
The whole solution runs on our own infrastructure and carries a written performance guarantee: 99.9% availability measured annually and a target load time under 2 seconds on a stable 4G connection on tested devices.
What we build
- a project website built for the project, not a template
- an interactive 3D model of the complex with clickable units
- architectural visualisation and photorealistic renders of the building and its surroundings
- a page for each apartment with the floor plan and areas
- a 360° virtual tour with labelled rooms
- a real-time 3D walkthrough of the apartment
- day and night rendering and several viewing angles
- live status: available, reserved and sold
- filtering, comparison and saved favourites
- an admin interface for the sales team
- enquiry forms and viewing reservations
- hosting, security, backups and monitoring
A project website is not a brochure, it is a sales tool
When selling a new development, the website is often the buyer's first real contact with the property and the location. That is where they decide whether to look further, send an enquiry, book a viewing or keep searching elsewhere.
During a sale the unit data changes almost every week: a unit is reserved, a price is adjusted, a storage unit is added. When the site has to be edited by hand for every change, it falls out of date fast - and the buyer is reading information that is no longer true.
- the buyer explores the project in detail before the first call
- the sales team receives better-informed enquiries
- less time goes into repeating basic information
- the developer sees which units attract interest
360° virtual tour and real-time 3D walkthrough
The buyer enters the apartment straight from the website. In the 360° tour they move between panoramic points and look around in every direction. In the real-time 3D walkthrough they move through the apartment freely - with keyboard or mouse on a computer, by touch on a phone.
- labelled rooms: living room, kitchen, dining area, bedroom, bathroom, terrace
- a mini floor plan showing position and viewing direction
- full-screen mode
- free movement through the space in the real-time walkthrough
- a better sense of room sizes, layout and how the spaces connect
What the platform is for: selling faster
A new development often sells over one, two or three years. For all that time the developer's capital is tied up in the project while financing costs keep running. So we do not treat the system as a website to be built and handed over, but as a sales tool for the entire selling period.
The platform shortens the path from first look to reservation. The buyer explores the project and the individual apartment in detail before the first contact with a salesperson, so the sales team receives much better-prepared enquiries and spends less time repeating basic information.
- apartments sell faster
- a better presentation of the project
- fewer routine questions for the sales team
- more high-quality enquiries
- a clearer picture of which units buyers are interested in
- a professional first impression of the project
The arithmetic is simple: if the solution helps sell even one apartment sooner, its value is far greater than the cost of building it. How many apartments sell, and how quickly, depends on location, price and the market - nobody who knows the business promises that. What we do promise is a tool that does not get in the buyer's way, and a written guarantee that it works.
Who we build this for
Architects and design practices
Architectural visualisation, photorealistic renders and spatial views of a project for the client, a competition or the public - produced from your design documentation.
Developers and construction companies
A complete sales platform for a residential complex: website, interactive model, apartment tours and an admin interface for the sales team.
Estate agencies
Virtual tours and availability views for the projects you market, connected to the way you work and to your existing systems.
The page for each apartment
Every apartment has its own page. In one place the buyer sees everything they need to decide whether it is worth a viewing.
- the apartment floor plan and, where useful, plans of every floor
- the area of each room and the total area
- balcony, loggia, terrace, garden, storage and parking
- a gallery of renders and a button for the virtual tour
- status and availability, updated live
- an enquiry form and a viewing reservation
- a PDF summary of the unit for the buyer
Interactive 3D model of the complex
The core of the platform is a visual view of the whole project. On the model of the complex the visitor picks a building, a floor and an individual apartment directly - with no spreadsheets or PDFs to dig through.
- clickable units marked available, reserved or sold
- choosing a building and a floor directly on the model
- several viewing angles and 360° rotation of the complex
- day and night rendering of the project
- key unit data on click: floor, rooms, area, floor plan, status
- a link through to the individual apartment page
Colour-coded availability
Every unit on the model is coloured according to its status, so a buyer sees at a glance what is still available. Instead of searching a spreadsheet or a PDF they click the apartment they are interested in and its page opens.
- green, amber and red marking on every unit
- views by building, by floor and by unit type
- unit data on hover or tap: floor, rooms, area
- a click opens the apartment page with the plan and the tour
- a filter that shows only available apartments
- a status change is visible immediately on every device
The colours are read from the sales records. When the sales team changes a status in the admin interface, the view updates at once - with no new render and no developer involved. It also puts an end to out-of-date lists circulating among buyers.
Works on every device, including older ones
Large renders, 360° panoramas and 3D models are demanding for a mobile device. A poorly prepared 3D view loads slowly, stutters, overheats the phone and burns through data - and the buyer leaves before it finishes loading.
The system therefore adapts the quality of the content to the device and the connection. Capable devices get the richer view; on older ones the demanding 3D walkthrough is automatically replaced by an optimised 360° tour. The buyer never has to think about technical requirements.
- iPhone, Samsung, Xiaomi and Google Pixel phones
- iPad and Android tablets
- Windows and macOS computers
- the Safari, Chrome, Edge and Firefox browsers
- progressive loading of large 3D content and panoramas
- a report on the testing carried out, delivered with the project
An AI sales agent on the project website
Most enquiries about apartments arrive in the evening, at night and at weekends - exactly when the sales team is unavailable. We can add an AI sales agent to the platform that answers immediately, using the live data of that project rather than generic phrases.
The agent sees live status and prices, so it never offers a unit that is already sold. If the visitor says what they are looking for, it suggests the closest matches and links them to the presentation or the 3D tour. Interested buyers are recorded and handed to the sales team.
- answers about apartments, areas, room counts, floor, parking and storage
- answers about the location, expected timelines and availability
- a shortlist of the most suitable apartments for what the visitor wants
- booking a viewing directly into the seller's calendar
- recording an interested buyer and handing them to the sales team
- a link to the client's CRM where one is in use
The agent has limits built in: it does not offer discounts, does not enter into contracts, gives no legal or financial commitments and promises no timelines that are not confirmed. When it does not know an answer, it hands the conversation to a salesperson. The client approves the tone and manner of communication before launch.
Admin interface for the sales team
The developer or the sales team gets their own access and updates the data that changes most often during a sale, with no developer involved. The changes appear immediately on the website and in the interactive model.
- unit status: available, reserved, sold
- prices and availability
- descriptions, parking spaces and storage units
- specific data for an individual unit
- an overview of enquiries and interest per unit
Our own infrastructure: that is why it does not stutter
The whole solution runs on server infrastructure we manage ourselves - the website, the database, the 3D model and the virtual tours. Among property sales platforms that is unusual: most suppliers put the website on third-party hosting and buy the virtual tours as an external service with a monthly licence.
The difference shows exactly where it matters most for selling. When a third-party platform runs the 3D model and the tours, nobody controls how fast they load or how they behave on an older phone. On projects with large renders, 360° panoramas and 3D models the infrastructure is decisive.
What a poorly optimised 3D view causes
Slow loading, stuttering, an overheating phone, excessive data use and a poor experience - the buyer leaves before ever seeing the apartment.
- optimised hosting, database and a global network for fast content delivery
- optimisation of images, 3D content and 360° panoramas
- automatic adjustment of content quality to the visitor's device and connection
- security, access control, backups and monitoring
- technical and security updates, plus compatibility with new devices and browsers
- one point of contact for the website, the 3D view, the database, hosting and support
Because it all runs with us, we tune the delivery as we go. If the speed measurements slip, we fix the content or the server settings straight away - with no waiting for an outside supplier and no argument over whose problem it is.
A written performance guarantee
We guarantee the solution in writing, not verbally. The guarantee is part of the offer and covers platform availability, loading speed and how the 3D system behaves on real devices.
- iPhones from the last four generations, plus mid-range and higher Samsung, Xiaomi and Google Pixel devices
- iPad and Android tablets
- Windows and macOS computers
- current versions of the Safari, Chrome, Edge and Firefox browsers
- on handover the client receives a report on speed and the testing carried out
Availability
99.9% availability of the web platform, measured annually.
Speed
The target load time for the core interface is under 2 seconds on a stable 4G connection on tested devices. Large 3D content and panoramas load progressively, in optimised form.
3D system behaviour
We test the 3D model and the tours on a range of devices and screen sizes. Where a device cannot handle the real-time walkthrough, the system switches automatically to the optimised 360° version.
Built for the project, not from a template
The website and the 3D system are made for the specific project. We do not use bought templates, generic plugins or third-party virtual tour platforms with extra monthly licences.
With generic tools the project has to fit the system. Here the system fits the project: the user experience, the way information is presented, the filters, the 3D model, the tours and the sales process follow how the developer actually sells property.

FAQ
What is the difference between a 3D visualisation and a virtual tour?
A visualisation is a picture: one view of a building or a room, rendered from a 3D model. A virtual tour is a space the visitor moves through - in a 360° tour they turn on the spot, in a real-time walkthrough they walk through the apartment. Visualisation suits the home page, advertising and print; tours help the buyer decide whether they want to see the apartment in person. Most projects use both.
What determines the scope of the visualisation and tour work?
It depends on the number of buildings and unit types, on how many exterior views and interior rooms are to be rendered, on whether a real-time walkthrough is needed alongside the 360° tour, and on how detailed the design documentation we receive is. We agree the scope after reviewing the documentation, before any work starts.
Can a buyer see which apartments are still available on the model?
Yes. Every unit is coloured by status: green for available, amber for reserved, red for sold. The buyer can show only the available apartments, and a click opens the page for the chosen unit with its plan, areas and tour. The colours are read from the sales records, so what is shown always matches what the sales team maintains.
Why does it matter that the platform runs on your own infrastructure?
Because with large renders, 360° panoramas and 3D models the buyer's experience is decided by loading speed. When a third-party platform runs the tours, nobody controls how they behave on an older phone. We optimise the content ourselves, adapt it automatically to the device and the connection, and guarantee the performance in writing.
Does the platform make apartments sell faster?
It is built to shorten the path from first look to reservation: the buyer explores the apartment in detail before the first call, and the sales team receives better-prepared enquiries and loses less time on basic questions. How many apartments sell, and how fast, depends on location, price and the market; that we do not promise.
Can you add an AI agent that answers buyers on the site?
Yes. The AI sales agent answers questions about apartments, areas, the location and availability using the project's live data, suggests suitable units, books viewings and hands interested buyers to the sales team. It offers no discounts, enters into no contracts and promises no unconfirmed timelines.
Do you produce architectural visualisation without a website?
Yes. From the design documentation we build the 3D model, renders of the building and its surroundings and spatial views for a client presentation, a competition or publication. The web platform is a separate service, added when the project goes on sale.
How does the virtual apartment tour work?
The buyer enters straight from the website, with nothing to install. In the 360° tour they move between panoramic points and look in every direction; in the real-time walkthrough they move through the apartment freely. Rooms are labelled, and a mini floor plan and full-screen mode are available.
Does the 3D walkthrough work on a phone?
Yes. The system adapts the quality to the device and the connection. On capable phones the real-time walkthrough runs; on older ones it is replaced by an optimised 360° tour, so the page does not stutter or consume excessive data.
Can the sales team change statuses and prices themselves?
Yes. The sales team gets an admin interface for unit status, price, availability, description, parking and storage. Changes appear immediately on the website and in the interactive model, with no developer involved.
What do you need from us to start?
The design documentation and floor plans, a unit schedule with areas, material about the location, and which unit types should be prepared for tours. If something is missing, send what you have; we agree the scope after reviewing the documentation.
Do you maintain the platform while the project is selling?
Yes. A development sells over a long period, so we look after hosting, security, backups, monitoring and updates, and compatibility with new devices and browsers. The client has one point of contact for the whole solution.
