Still CGI renders and walkthrough animations serve different purposes — and the right choice depends on your scheme size, marketing stage, and budget. Still renders, priced from around £450 per image, excel at planning submissions, property portals, and print brochures, where a single carefully composed viewpoint communicates design intent with maximum efficiency. Walkthrough animations, starting from approximately £2,500 per minute of finished footage, earn their cost when you need to convey spatial sequences, relationships between interconnected spaces, or the premium feel of a development at a launch event or investor presentation. The key cost difference is significant: a five-image package typically runs between £2,500 and £4,500, whereas a comparable two-minute animation can reach £4,500 to £9,000 with a production timeline of four to eight weeks. For most UK residential developers working on schemes of under 50 units, still renders deliver the strongest return on investment — especially at the planning and early sales stages. Animation becomes the more compelling investment once a scheme reaches launch phase or investor engagement.
It is one of the most common questions we receive at 3D Vistas: should the marketing budget go towards a suite of photorealistic still renders, or is a walkthrough animation the better investment? The honest answer is that both formats are created from the same underlying 3D model and both can be equally photorealistic — the difference lies in what each format communicates, and to whom. Getting this decision wrong costs money in one of two directions: either you commission animation you did not need, or you under-invest and fail to communicate your scheme effectively to investors or buyers who expect video content. This guide lays out the practical decision framework we use with developers, architects, and planning consultants across the UK.

The Core Difference: A Moment vs a Journey
At a technical level, still renders and walkthrough animations are produced from exactly the same ingredients: a 3D model of your building, applied material and texture maps, a configured lighting environment, and a rendering engine that simulates how light behaves in the real world. The output is photorealistic in both cases. The fundamental difference is temporal — a still render captures one perfectly composed moment in time, whereas animation moves the viewer through that same environment across a duration.
That distinction matters more than it might initially appear, because the two formats engage different cognitive processes in the viewer. A well-composed still render works like a photograph: the viewer’s eye is guided by the composition, and they can absorb the image at their own pace, returning to details and reading materials and finishes at leisure. This makes stills highly effective for analytical audiences — planners, architects, and investors studying a scheme’s design quality. Animation, by contrast, creates an experiential journey. The viewer is carried through the space; they feel the scale of a double-height lobby, understand how a courtyard connects to a communal roof terrace, or sense the quality of natural light in a living room as the camera pans across it. Animation appeals to emotion and spatial intuition rather than analytical study, which is why it performs particularly well with end buyers and in high-stakes presentations where you need your audience to feel connected to a development rather than simply informed about it.
When Still Renders Are the Right Choice
For the majority of UK residential development projects — particularly those under 50 units — still CGI renders deliver the best balance of impact and cost efficiency. Planning applications are perhaps the clearest case: local planning authorities across England and Wales assess schemes through submitted documentation, and the standard format for design and access statements is static imagery. Planning officers are not set up to review animation files, and many LPAs would not accept them as part of a formal application anyway. High-quality exterior stills showing the proposed elevation in context, alongside interior material boards, are exactly what a planning submission requires.
Beyond planning, stills work superbly for Rightmove and Zoopla listings, where a sequence of five or six photorealistic images — exterior street view, key interior rooms, kitchen, living space, and a garden or amenity area — gives prospective buyers everything they need to decide whether to enquire. Print brochures and investor summary decks are also natural homes for stills: the image holds on a page in a way that video cannot. Pricing for still renders in the UK typically runs from £450 to £900 per individual image, with five-image packages available from £2,500 to £4,500 depending on complexity, the number of bespoke material finishes required, and whether aerial or dusk variants are included. Turnaround times of one to two weeks make stills a practical choice at any stage of the development cycle, including when planning approval is imminent and marketing materials are needed quickly.
When Walkthrough Animation Is Worth the Investment
There are specific scenarios where walkthrough animation justifies its higher cost, and it is worth being precise about what those scenarios are. Large mixed-use developments — schemes combining residential with commercial ground-floor uses, amenity spaces, car parking, and public realm — often have spatial relationships that simply cannot be communicated by even a comprehensive set of stills. How do residents move from the car park to the lift core? What does the journey feel like from the entrance lobby to the communal roof terrace? Animation answers these questions in a way that no static image can.
Flagship residential schemes targeting premium buyers benefit substantially from animation, particularly when those buyers are purchasing off-plan. A two-minute walkthrough that moves through a show apartment, out onto a private terrace, and down to a residents’ gym creates an emotional connection to a space that does not yet exist — and for a buyer committing £800,000 or more off-plan in Manchester, Leeds, or London, that emotional connection can be the deciding factor. Developer presentations to institutional investors and fund managers are another strong use case: investors allocating capital to a scheme expect a professional video presentation, and animation significantly elevates the perceived credibility of a pitch. Post-pandemic, video content has become an expected default on development websites, and analytics consistently show that animation increases average dwell time on project pages — giving more opportunity to convert a visitor into a lead.
Costs Compared: A Realistic UK Price Guide
Understanding the true cost of each format requires looking beyond the headline fee to include revision costs, production time, and the downstream uses each asset can serve. Here is an honest comparison based on current UK market rates.
Still CGI renders: A single exterior or interior still render typically costs between £450 and £900. A five-image package — the most common starting point for residential marketing — runs from £2,500 to £4,500, with complexity, bespoke landscaping, and multiple lighting variants (daytime and dusk, for example) pushing towards the upper end. Turnaround time is one to two weeks from brief sign-off. Revision costs at the render stage are relatively modest, typically £150 to £300 per round of amendments.
Walkthrough animation: A sixty-second finished animation starts from around £2,500 and can reach £5,000 depending on the complexity of camera moves, the number of distinct spaces covered, and whether licensed music and professional colour grading are included. A two-minute animation — which is the most common format for a residential launch — typically costs between £4,500 and £9,000. Production time runs from four to eight weeks. This is the critical difference: unlike stills, where revisions after delivery are straightforward, changes to an animation after the final render stage are expensive — potentially £500 to £1,500 per sequence — because individual frames must be re-rendered and recomposited. This makes thorough sign-off at the animatic stage essential (see the production section below).
The Production Process: What to Expect
Understanding how each format is produced helps you plan your project timeline and avoid the most common source of cost overruns: late-stage change requests.
Still renders follow a relatively streamlined process: you provide a brief covering viewpoints, material preferences, landscaping direction, and lighting mood; the studio builds or adapts the 3D model; test renders at reduced resolution are issued for client review and feedback; once approved, the final high-resolution renders are produced and delivered, typically as 300 DPI TIFF or high-quality JPEG files suitable for both print and digital use. The iterative review stage at the test render point is where to make all significant changes — adjustments to materials, camera angle, soft landscaping, and lighting can be made efficiently at this stage.
Walkthrough animation involves a longer and more collaborative production commitment. After the initial brief, a storyboard is produced that sets out the camera path, key scenes, pacing, and narrative arc of the animation. This storyboard must be signed off before modelling begins. Once the 3D model and environments are built, an animatic is produced — a low-resolution preview that shows the camera moving through the space in real time, without final lighting, materials, or detail. The animatic stage is the critical checkpoint: this is where you approve the camera journey, the sequence of spaces, the timing of each shot, and the overall pacing. Changes after the animatic is approved become progressively more expensive because every amendment requires re-rendering individual frames. After the animatic is signed off, the studio proceeds to full rendering — which for a two-minute animation at HD resolution can mean tens of thousands of individual frames — followed by colour grading, music and audio layering, and final delivery in MP4 or MOV format for web, event, and social use.
The Hybrid Approach Most UK Developers Use
In practice, the most commercially effective strategy for UK residential developers is not a binary choice between stills and animation — it is a phased approach that uses each format at the stage where it delivers the most value. The pattern we see most often works as follows: still renders are commissioned first, at the planning and pre-sales stage, to support the planning application, populate the Rightmove listing, and give the sales team printed brochure material. These stills are typically delivered four to eight weeks before planning determination, giving the team marketing collateral from the earliest possible moment.
Then, at the point of main marketing launch — often coinciding with a launch event or the opening of a sales suite — animation is commissioned to create the centrepiece of the digital campaign. Critically, because the 3D model was already built for the still renders, the animation studio is not starting from scratch. The model, materials, and lighting environments are already established; the animation work builds on top of this existing asset, which meaningfully reduces the animation cost — sometimes by 20 to 30 per cent compared with commissioning animation without any prior CGI work on the scheme. This phased approach also manages cash flow: the still render investment is made when planning consent is being sought, and the larger animation investment is made when sales revenue is beginning to flow. Animation content then serves the development website homepage, launch event presentations, social media campaigns, and investor relations materials throughout the sales period.
How to Decide: Five Questions to Ask Yourself
If you are still weighing up which format is right for your current scheme, work through these five questions in order. They cover the factors that most reliably predict whether animation will deliver a return.
1. What is my total marketing budget for CGI? If your CGI budget is under £5,000, commission stills. A strong five-image package will give you planning-quality imagery and portal-ready assets. If your budget is over £10,000, a hybrid approach — stills for planning and early sales, animation for the launch campaign — becomes viable and is usually the recommended route.
2. Do I have a launch event or an investor presentation? If yes, animation almost always justifies itself. A two-minute walkthrough played on screen at a launch event, or embedded in an investor deck, elevates the professional quality of the presentation in a way that a printed still cannot replicate. The cost of the animation is modest relative to the value of the funding or sales it supports.
3. How many distinct spaces does my scheme need to communicate? If your scheme has more than eight or ten meaningfully different spaces — separate unit types, interconnected amenity areas, external courtyards, roof terraces, underground parking, and so on — animation conveys the spatial relationships between those areas far more effectively than a collection of stills, which viewers must mentally assemble into a coherent picture of the scheme.
4. What is my production timeline? If you need finished assets in under six weeks, animation may not be feasible given current studio capacity and the four-to-eight-week production schedule. Stills can be produced in one to two weeks, making them the only practical option when timelines are tight — for example, when a planning decision has come through unexpectedly quickly and the sales team needs to go live immediately.
5. Who is my primary audience? Institutional investors and fund managers expect video; stills in a funding presentation can signal under-investment in marketing. Premium buyers purchasing at the higher end of the market — properties above approximately £600,000 in regional cities, or above £1 million in London — increasingly expect an immersive visual experience. First-time buyers and mid-market owner-occupiers finding your scheme on Rightmove or Zoopla are well-served by strong photography-quality stills. Match the format to the audience, and the investment will pay for itself.
