Interior CGI and Visualisations for London Properties
Interior CGI London produces photoreal still images as the architectural representation layer for architects, residential developers, sales agents, interior designers, hospitality operators and private clients.
The service covers prime residential, show apartments, hospitality, workplace, retail showroom and heritage interiors. Day, dusk, night and material-swap variants are scoped from plans, sections, BIM models or finish schedules and delivered at print and digital resolution. Each image is scoped around a design decision or sales deadline, from RIBA design sign-off to off-plan marketing and investor review.
Interior CGI in London is commissioned by six distinct teams, each one bringing a different design or commercial question to the project and a different downstream reader for the final image.
Architects working RIBA stage 3 to 4 use interior CGI to test volume, daylight reach, joinery proportion and material junctions before construction drawings issue.
The handover usually arrives as a Revit or IFC model with reflected ceiling plans and a finish schedule. The final image goes to a planning case officer, the project architect on a coordination call, or the client signing off the design package.
Interior designers commission interior CGI when colour, texture, FF&E and lighting decisions need a spatial reference more honest than a flat moodboard. The image goes to the private client at sign-off, then enters supplier conversations with joinery and lighting workshops where the rendered material has to match the procurement specification.
Workspace lobby in a London developer scheme. Interior designers and developers commission this kind of CGI to test arrival sequence, reception joinery and finish before construction completes.
Residential developers launching off-plan in Canary Wharf, Nine Elms, Battersea Power Station, White City and Wembley Park use interior CGI to fill a marketing pipeline with no built interior to photograph.
Hero units, typical floorplans and amenity floors are visualised from the BIM model and finish standard pack, then deployed across Rightmove, the developer microsite and the on-site sales suite.
The three deliverables a developer brief usually opens with: hero unit, typical floorplan and amenity floor.
Sales agents handling prime and super-prime listings in Belgravia, Mayfair, Knightsbridge, Notting Hill and St John's Wood use interior CGI when an empty listing sits too long against neighbouring stock that is already staged or furnished. The deliverable is portal-ready stills sized for Rightmove, Zoopla, OnTheMarket and PrimeResi, calibrated to the listing's price tier.
Hoxton workspace interior. Hospitality lobbies, restaurant interiors and creative workplace floors share the same modelling logic, with day, dusk and night variants per camera.
Hospitality operators use day, dusk and night variants of lobby, suite, restaurant, bar and amenity interiors well before opening to feed three downstream audiences in parallel: hotel debt and equity raises, brand investor decks, and pre-opening trade press and travel media. The brand book and finish palette dictate the lighting and styling register.

Private clients in Belgravia, Mayfair, Kensington, Chelsea and Hampstead commission interior CGI to test finish, joinery, lighting and styling decisions before procurement spend commits. The image is normally reviewed with the interior designer in the room, then carried to joinery and lighting suppliers as the procurement reference for shop drawings and orders.

Interior CGI Project Types
Interior CGI for every London brief
London interior CGI briefs cover six project types. Each one asks a different visual question, so the camera language, finish detail and revision focus shift accordingly.
Prime and super-prime residential interior CGI
Belgravia, Mayfair and South Kensington interiors use CGI to lock joinery, stone, fabric and daylight decisions before client sign-off or listing launch.
Show apartment and sales-suite CGI
BTR, PRS, co-living and student schemes use show-apartment CGI to support portal listings, sales-suite walls and brochure image sets before the building is complete.
Hospitality interior CGI
Mayfair, Soho and West End hospitality teams use lobby, suite, restaurant and bar CGI for investor packs, brand approvals and pre-opening press material.
Workplace interior CGI
Canary Wharf, Clerkenwell and White City office briefs use CGI to test reception sequence, floor-plate density, breakout furniture and amenity-floor leasing imagery.
Retail and showroom interior CGI
Chelsea, Marylebone and Clerkenwell showroom CGI supports kitchen, bath, furniture and gallery decisions where product finish, lighting temperature and circulation drive the sale.
Heritage and period interior CGI
Camden, Islington, Westminster and Southwark period interiors use CGI to show retained cornicing, fireplaces, sash windows and new intervention details in the same camera.
Interior CGI Deliverables
What an interior CGI package delivers for sign-off and marketing
An interior CGI package resolves a set of decisions, not a fixed bundle. Viewpoint count, lighting variants, file formats and revision rounds are agreed at scoping stage and tied to the planning, sales or design-review job.
Photoreal stills for planning, sales, brochure, investor and design-review packs.
Day, dusk, night and golden-hour variants where the same camera needs different lighting registers.
360° panoramas for sales suites, stakeholder review or room-by-room digital tours.
Walkthrough animation for moving-image briefs, scoped through the 3D animations service.
VR tour scenes for immersive review when static viewpoints do not cover the decision.
Material-swap variants comparing option A against option B without rebuilding the room.
White-box and furnished versions so geometry can be approved before styling begins.
Aspect-ratio variants for Rightmove, OnTheMarket, brochures, social crops and presentation decks.
Delivery formats per use: JPEG sRGB for portal and brochure release, TIFF 16-bit for print and editorial reproduction, PNG alpha for compositing handover, EXR multi-pass for downstream colour grading and post-production.
CGI Production Stack
Interior CGI Production Stack: Render Engines, BIM Inputs and Real-Time
Production here runs Chaos V-Ray, Chaos Corona and Epic Unreal Engine in parallel, because a Hampstead townhouse interior, a Canary Wharf show apartment and a hotel lobby walkthrough are three different rendering problems, each suited to a different render path.
Photoreal render engines: V-Ray and Corona on Autodesk 3ds Max
Interior CGI for London projects renders primarily through Chaos V-Ray and Chaos Corona Renderer, both running through Autodesk 3ds Max as the modelling host.
Chaos Corona suits plug-and-play photorealism for residential and hospitality interior visualisation across Belgravia, Mayfair and Hampstead. Chaos V-Ray suits scene-specific control on Westminster prime residential and large Canary Wharf mixed-use interior CGI. Blender, Lumion and Otoy Octane sit alongside for interior workflows where they fit the project.
BIM and CAD inputs: Autodesk Revit, IFC and AutoCAD
Interior visualisation production accepts Autodesk Revit and IFC models, AutoCAD plans, sections and reflected ceiling plans, finish schedules, FF&E specifications, and Hilton, IHG, Marriott or independent brand and style guidelines where they exist.
A clean BIM handover compresses the white-box stage. Geometry is confirmed against the production model before the first viewpoint draft is approved, so review rounds with RIBA-chartered architects address lighting and finish rather than spatial corrections.
Real-time interior review with Epic Unreal Engine
Epic Unreal Engine supports interior CGI projects that need an interactive walkthrough, real-time material review or a live design-review session. Architects, BIM managers and interior designers navigate a shared scene rather than passing static images between consultants.
Unreal Engine sits alongside, not in place of, the static Chaos V-Ray or Chaos Corona photoreal interior visualisation deliverable, so the still-image evidence pack and the live review run on the same project. For longer-form animation, see 3D animations.
Rather than presenting buyers with cold, empty rooms, CGI virtual staging and digital furniture styling bring interior architectural layouts to life. We model and style vacant spaces to display highly styled, premium lifestyles that accelerate off-plan reservations.
Curating high-end digital furniture and realistic spatial layouts
Custom Furniture Staging: We populate empty rooms with curated 3D digital furniture matching the specific demographic of the target development. From contemporary Scandinavian minimalism to rich classic Belgravia luxury, every item is modeled to scale to respect the room's physical dimensions.
Spatial Flow & Scale: Empty rooms often appear smaller than they are. Digital staging establishes visual cues for scale, layout circulation, and room function. Observers immediately understand where the bed fits, how the lounge links to the balcony, and the overall spatial depth.
Simulating material textures: PBR fabrics, wood grains, and stone finishes
PBR Texture Shaders: Every stage element uses Physically-Based Rendering shaders to represent correct surface details. This ensures fabric weaves (such as boucle, linen, or velvet) scatter light naturally, while oak floorboards and marble worktops show realistic grain and specular reflections.
Atmospheric Lighting Cohesion: Curated staging elements are not simply copy-pasted; they are fully integrated into the room's daylight environment. Soft shadow casting, diffuse ambient bounces, and local light rays from staged floor lamps create a unified, warm, and highly realistic interior experience.
CGI vs AI for Interior Imagery
AI image tools for ideation, photometric interior CGI for sign-off
AI image tools generate pixels from text prompts and reference images, with no underlying 3D scene behind the picture. That output suffices for ideation moodboards. The same output fails the moment a planning officer asks for the same scheme from a different camera, or a client asks to see the room with the specified fabric on the specified chair.
A photometric interior CGI built in Chaos V-Ray or Chaos Corona on an Autodesk Revit-aligned 3ds Max scene behaves as a structured 3D model, not a pixel surface. Every camera, light, fixture, fabric and FF&E item is a named, versioned asset. Swap the sofa, and the scene reprocesses with the new sofa under the same camera, light and finish six months later.
RIBA stage 3 sign-off, planning consent imagery, off-plan brochure release, FF&E procurement and investor packs all need a deliverable that reprocesses on demand. AI image tools serve the ideation phase. Photometric CGI serves the sign-off.
Interior CGI by RIBA Stage

Interior CGI by London Borough
Interior CGI by London borough
Interior CGI briefs cluster around specific boroughs and typologies. These borough pages cover wider planning context for location-specific interior, facade and streetscape briefs.
Interior CGI scoping depends on the drawings, finishes and reference assets the project supplies. The more drawings, finishes and references arrive at scoping stage, the faster the white-box stage closes and the closer the first draft comes to the final image.
Plans, sections and elevations with the latest issue date.
Reflected ceiling plan and lighting plan with luminaire schedule where available.
FF&E specification with named suppliers, product references, fabric codes and furniture dimensions.
Mood board, reference imagery and target camera register for the intended buyer or reviewer.
BIM, Revit or IFC model if the project already has coordinated geometry.
Existing site photography for retrofit, refurbishment and period-property work.
Brand guidelines for hotel, restaurant, bar, workplace or developer-marketing briefs.
Output use, image count, required ratios, deadline and review milestones.
Interior CGI Process
From white-box to final interior CGI
Each stage produces a visible deliverable, so review rounds focus on geometry first, finish second and lighting third rather than mixing decisions across stages. For a broader view of how we manage CGI commissions, visit our process page.
Briefing and scoping define the decision the imagery must support.
White-box or volumetric modelling locks camera position, room proportion and sightline. A clay preview confirms massing and scale under neutral grey shading before finish work begins.
Material and texture pass checks floor, wall, ceiling, joinery and fixed elements against the finish schedule. Sample-board sign-off and material approval then close the step against the procurement specification.
Lighting pass tests daylight, sun direction and luminaire output against the room's intended use through staged test renders, so review focuses on measured brightness and colour temperature rather than impression.
FF&E and styling pass positions the specified furniture, fixtures and equipment alongside artwork, planting and dressed details.
Draft review and final delivery provide JPEG sRGB, TIFF 16-bit, PNG alpha and EXR multi-pass files at print and digital resolutions.
Interior CGI FAQ
Frequently asked questions about interior CGI in London
Six questions we answer at scoping stage on most London interior CGI briefs.
What drives the cost of an interior CGI in London?
Cost on a London interior CGI project tracks several variables: viewpoint count, room count, finish detail, lighting variants, revision rounds, brand-guideline alignment, and the required level of material accuracy. A single hospitality lobby with day, dusk and night variants takes more production time than three viewpoints of a residential living room. The quote is scoped against those variables for each commission.
Can interior CGI be produced before site or construction is finished?
Yes. Off-plan show apartments, sales suites and developer marketing imagery are produced from drawings, BIM models and finish schedules well before completion. The interior CGI behaves as the brochure, portal and design-review image set until built photography is available.
How accurate is material representation in interior CGI?
V-Ray and Corona Renderer use physically based materials and IES light profiles, so timber, stone, plaster, joinery, brass, fabric, glazing and paint can match a finish schedule rather than approximate it. Material accuracy depends on what the finish schedule supplies. Real swatches, supplier names or scanned textures produce closer alignment than generic references.
Do you accept Revit, BIM or AutoCAD inputs?
Yes. Revit and IFC models, AutoCAD plans, sections, reflected ceiling plans, finish schedules and FF&E specifications are all accepted as primary inputs. A coordinated BIM model means the white-box stage closes on the first iteration instead of running through repeated geometry corrections.
What viewpoint count is typical for a London interior CGI brief?
Viewpoint counts scale to the decision the imagery supports rather than a default number. Residential projects commonly span a handful of viewpoints per scene; hospitality and workplace projects commonly run wider sets across lobby, breakout, suite and restaurant interiors, agreed at scoping stage.
What is the difference between sign-off imagery and marketing imagery?
Sign-off imagery proves a design decision: stair headroom, joinery proportion, daylight reach, material junction. Marketing imagery sells the finished space: mood, lighting, styling, atmosphere. One model can produce both outputs, but the planning version and the marketing version need separate specification so neither overstates the other.
