How long does a 90-second architectural animation take to produce?

Standard residential 1080p from a complete brief: 3-4 weeks. Marketing-grade 4K: 5-8 weeks. Phases: brief review and model build (1-2 weeks), camera path and lighting (1 week), cloud farm render (1-2 weeks at complex 4K spec), post-production (1 week). Rush delivery: 25-50% premium, can compress Tier 1 to 2 weeks, but cannot reduce physical render time for complex 4K below a production floor.

Architectural Animation Services: What Your Project Costs Per Second

Q: How much does architectural animation services cost per second in 2026?

Four tiers in GBP: Standard residential walkthrough £120-£180/sec. Marketing-grade development animation (4K, exterior + interior, voiceover option) £300-£480/sec. Cinematic commercial film (broadcast grade, motion graphics) £600-£1,200/sec. Realtime interactive (Unreal Engine 5 / D5 Render) £150-£300/sec. Tier is determined by scene complexity, not duration. 90-second Tier 1: £10,800-£16,200. 90-second Tier 2: £27,000-£43,200.

Q: What makes one architectural animation more expensive per second than another?

Four variables: scene complexity (number of distinct environment types, each requires its own geometry build), render resolution (4K multiplies per-frame render time approximately 4x vs 1080p), post-production requirement (voiceover, colour grade, motion graphics, delivery formats), and frame rate (60fps = 2.4x more frames than 25fps for same duration). Two 90-second animations can have radically different per-second costs depending on these variables.

Q: What is the difference between offline-rendered and realtime architectural animation?

Offline-rendered (V-Ray 7, Corona 12): each frame rendered independently by CPU/GPU ray tracing, 2-4 min/frame (simple 1080p) to 45-90 min/frame (complex 4K). Higher quality ceiling. Realtime (Unreal Engine 5 Lumen, D5 Render): hardware-accelerated GI at near-real-time speeds. Enables client-navigable walkthroughs and VR experiences. Slightly lower quality ceiling than best offline work. Use offline for portal/sales suite videos; use realtime for interactive sales tools.

Q: What should I include in an architectural animation brief for an accurate quote?

Eight items: duration target, environment types and count (exterior / interior rooms / public realm / aerial, each counted separately), lighting scenarios (daylight / evening / day-night transition), resolution (1080p or 4K), frame rate (25fps standard or 60fps for interactive/VR), voiceover requirement, post-production grade, and delivery formats. Also: CAD files in DWG, DXF, FBX, or OBJ. These determine the production tier and cost per second before the studio sees the project.

Broad price ranges for architectural animation services, “£120 to £1,200 per finished second”, carry the same problem as every generic guide: they describe the market but do not tell a developer where their project sits in it. The per-second cost of any architectural animation is determined by four production variables that have nothing to do with duration: scene complexity, render resolution, the number of distinct environment types in the brief, and the post-production requirement. This post explains how those variables determine the cost per second, what the four production tiers look like in GBP for 2026, how duration brackets map to brief types, and the one technical specification that doubles render cost without adding a single second of finished video.

This is a £300-£480 per finished second production tier, driven by scene complexity, not duration.

The Cost-Per-Second Calculation

The cost per second of an architectural animation services project is not a fixed rate multiplied by duration. It is:

Total project fee ÷ Total finished seconds = Cost per second

The total project fee is the sum of: modelling time (building and environment geometry), animation time (camera path choreography, entourage animation, lighting transitions), render time (cloud farm cost at the resolution and quality spec), and post-production time (colour grade, titles, voiceover, music, delivery formats).

A 90-second animation that is an exterior fly-around of a simple residential building, one camera path, clear sky background, minimal entourage, 1080p, no interior scenes, sits at the lower end of cost per second. A 90-second animation that combines 30 seconds of exterior context, 30 seconds of interior sequences across four rooms, and 30 seconds of branded motion-graphics reveal sits at the upper end, because modelling, render time, and post-production are all materially higher. Both are 90 seconds. The cost per second is not the same.

Understanding which side of each variable your project sits on before briefing a studio is the difference between an accurate budget and a quote that requires revision.

Duration does not determine where a project lands, scene complexity does. A 90-second Tier 1 standard residential walkthrough costs £10,800-£16,200. A 90-second Tier 2 marketing-grade development animation costs £27,000-£43,200. Same duration, different scene complexity, different cost per second.

The Invisible Cost Driver: Frame Render Time

Every second of a finished architectural animation at 25 frames per second contains 25 individual frames. Every frame is a full photorealistic still render. The time to produce one frame determines the entire production economics of the project.

What Changes Frame Render Time

Factor	Simple Scene	Complex Scene
Scene geometry	Single building, clear site	Dense urban context, 200-400m surroundings
Materials	Flat facades, simple glass	Wet stone, layered glass reflection, metal, patterned tile
Lighting	Single daylight sun-sky	Multi-source interior: IES fixtures, bounce, ambient + exterior
Entourage	3 tree assets	40+ species, animated people, vehicles
Resolution	1080p	4K
Render time per frame	2-4 minutes	45-90 minutes

At 25fps, 1 second of finished video = 25 frames:

Simple 1080p scene: 25 x 3 min = 75 minutes per second on one workstation
Complex 4K scene: 25 x 60 min = 25 hours per second on one workstation
Complex 4K scene on cloud farm (100 nodes): approximately 15 minutes per second at additional cloud compute cost

Cloud render farm cost for a complex 4K 3-minute architectural animation services project on 100 nodes: typically £800-£3,000 depending on scene complexity and render quality settings. This cost is included in Tier 2 and Tier 3 project fees.

This is the scene complexity that produces 45-90 minute per-frame render times, the reason Tier 3 costs £600-£1,200 per finished second.

The Frame Rate Decision

Most architectural animation services studios produce at 25fps, the UK broadcast and web standard. Some produce at 30fps (North America standard, some social platforms). The shift from 25fps to 60fps multiplies the frame count by 2.4x for the same duration.

At a complex 4K specification:

25fps, 90 seconds: 2,250 frames at 60 minutes each = 5,625 hours of compute (farm-distributed)
60fps, 90 seconds: 5,400 frames at 60 minutes each = 13,500 hours of compute (farm-distributed)

60fps is the appropriate specification for interactive and VR deliverables built in Unreal Engine 5, where real-time rendering absorbs the frame rate increase. It is not the appropriate specification for offline-rendered V-Ray or Corona architectural animation services at Tier 1 or Tier 2 unless the budget explicitly accounts for the 2.4x render cost increase.

Specifying 60fps for a photorealistic offline-rendered architectural animation without a corresponding budget increase either reduces quality (through lower per-frame render settings) or increases cost substantially.

Duration Brackets and What Fits in Each

Short-Form (60-90 Seconds)

Primary space or building. One camera path, one lighting scenario. No voiceover or minimal title cards. For: Rightmove/Zoopla video listings, developer social media (LinkedIn, Instagram Reels), pre-launch teasers. Most Tier 1 residential projects sit in this bracket.

Mid-Form (2-3 Minutes)

Multiple environments or views. One or two lighting scenarios. Voiceover narration at 120 words per minute (a 3-minute video = 360-word script). Title cards, animated branding, licensed music. For: sales suite screens, development website hero films, investor day presentations. Tier 2 marketing-grade projects typically fall here.

Long-Form (4-6 Minutes)

Full site context including surroundings and public realm. Aerial views, exterior sequences, interior sequences, branded post-production. Narration, motion graphics, full sound design. For: planning authority submissions, landmark project documentations, commercial property investment pitches. Tier 3 cinematic projects sit here.

The cost multiplier from short-form to long-form is not proportional. A 3-minute animation does not cost double a 90-second animation at Tier 2. It costs more because longer films also include more environment types, more scene changes, and higher post-production complexity, not simply more of the same simple scene.

Brief Checklist for an Accurate Quote

Before briefing an architectural animation services studio:

Duration target: 60-90 seconds / 2-3 minutes / 4-6 minutes
Environment types: exterior only / exterior + interior / exterior + interior + public realm + aerial
Number of interior spaces: each room is a separate environment build
Lighting scenarios: daylight only / daylight + evening / full day-night transition
Resolution: 1080p / 4K (with awareness of render cost implications)
Frame rate: 25fps (standard) / 30fps / 60fps (interactive/VR only)
Voiceover: yes (provide script or word count) / no
Music: licensed track (included in studio fee) / bespoke composer commission (additional)
Post-production: standard grade / broadcast master / motion graphics
Delivery formats: MP4 web / ProRes master / social compressed versions
CAD files: DWG/DXF floor plans and elevations or model files in .FBX / .OBJ

At RenderInfinity, every architectural animation services brief is reviewed for environment count and scene complexity before quoting, because duration alone does not determine production cost.

Quick Reference

Architectural animation services in 2026 are priced by production tier, not duration alone. Four tiers in GBP: Standard residential (£120-£180/sec), Marketing-grade development (£300-£480/sec), Cinematic commercial (£600-£1,200/sec), Realtime/interactive UE5 (£150-£300/sec). A 90-second standard residential walkthrough: £10,800-£16,200. A 3-minute marketing-grade development animation: £54,000-£86,400.
The invisible cost driver is frame render time, not duration. At 25fps, 1 second = 25 frames. A simple 1080p scene: 2-4 minutes per frame. A complex 4K scene (urban context, IES lighting, dense entourage): 45-90 minutes per frame. On a 100-node cloud farm, a complex 4K second costs approximately 15 minutes of compute time. Cloud farm cost for a 3-minute complex 4K animation: £800-£3,000.
60fps is the single technical specification that most dramatically multiplies render cost without adding finished seconds. It requires 2.4x more frames than 25fps for the same duration. Appropriate for Unreal Engine 5 interactive and VR deliverables. Not the default specification for standard web or portal architectural animation services at Tier 1 or Tier 2.
Duration brackets map to brief complexity: short-form (60-90 seconds) for portals and social, mid-form (2-3 minutes) for sales suite and investor use, long-form (4-6 minutes) for planning and major commercial launches. The cost multiplier between brackets is not linear, longer animations are typically also more complex, not simply more of the same scene.
Eight brief items determine which tier a project sits in before production begins: duration target, environment types and count, interior space count, lighting scenarios, resolution, frame rate, voiceover requirement, and post-production grade. Providing these at brief stage produces an accurate quote. Omitting them produces a quote that changes after the brief review call.

Frequently Asked Questions

How much does architectural animation services cost per second in 2026?

Architectural animation services cost between £120 and £1,200 per finished second in 2026 depending on production tier. Standard residential walkthrough (exterior, 1080p, basic entourage, no voiceover): £120-£180/sec. Marketing-grade development animation (exterior + interior, 4K, professional colour grade, licensed music, voiceover option): £300-£480/sec. Cinematic commercial property film (complex CGI environments, motion graphics, broadcast grade): £600-£1,200/sec. Realtime interactive (Unreal Engine 5 or D5 Render): £150-£300/sec. The tier is determined by scene complexity, not duration.

What makes one architectural animation more expensive per second than another?

Four variables determine per-second production cost: scene complexity (how many distinct environment types, each requiring its own geometry build), render resolution (4K multiplies per-frame render time approximately 4x versus 1080p), post-production requirement (voiceover, colour grade, motion graphics, delivery formats), and frame rate (60fps requires 2.4x more frames than 25fps for the same duration). Two animations of the same length can have radically different per-second costs depending on where each of these variables lands.

How long does it take to produce a 90-second architectural animation?

A 90-second standard residential walkthrough at 1080p from a complete brief: approximately 3-4 weeks. A 90-second marketing-grade development animation at 4K: approximately 5-8 weeks. Production phases are: brief review and model build (1-2 weeks), camera path and lighting development (1 week), render distributed across cloud farm (1-2 weeks at complex 4K spec), and post-production (1 week). Rush delivery carries a 25-50% premium and can compress a standard residential timeline to 2 weeks, but cannot reduce the physical render time for complex 4K scenes below a production floor.

What is the difference between offline-rendered and realtime architectural animation services?

Offline-rendered animation (V-Ray 7, Corona 12) produces each frame independently using CPU or GPU ray tracing. Frame times range from 2-4 minutes (simple 1080p) to 45-90 minutes (complex 4K) per frame. The quality ceiling is higher. Realtime animation (Unreal Engine 5, D5 Render) generates frames at near-real-time speeds using hardware-accelerated global illumination (Lumen in UE5) and can produce interactive deliverables, client-navigable walkthroughs, VR headset experiences, that offline rendering cannot. For portal and sales suite videos, offline-rendered is the quality standard. For interactive sales tools, realtime is the right specification.

What should I include in an architectural animation brief to get an accurate quote?

Specify: duration target, environment types and count (exterior, interior rooms, public realm, aerial, each counted separately), lighting scenarios, resolution (1080p or 4K), frame rate (25fps standard or 60fps for interactive), voiceover requirement, post-production grade, delivery formats, and CAD files in DWG, DXF, FBX, or OBJ format. These eight brief items determine which production tier applies and what the cost per second will be, before a studio has seen the project. Omitting them results in a quote that changes after the brief review call.

Conclusion

Every architectural animation services quote that comes back higher than expected is a response to a brief where scene complexity is higher than the client assumed. Duration is the visible variable. Scene complexity, how many environments, which resolution, what post-production deliverables, is the one that moves the per-second cost.

At RenderInfinity, the brief review call identifies scene complexity before quoting, so the price per second is predictable before production begins. Visit our architectural animation services page to request a brief review or quote for your development.
