Interior 3D Rendering

People buy a room by feeling it. Powerkh turns your BIM, CAD, or drawings into photorealistic interior CGI, with real lighting, materials, and furniture styling, so lobbies, offices, retail, and homes are understood and sold before the finishes are installed.

Interior 3D Rendering & CGI Services

Interior 3D rendering is the creation of photorealistic images of indoor spaces from a model or drawings. Lighting, materials, furniture, and styling are applied to rooms such as lobbies, offices, retail, and restaurants, then computed into stills, animations, or panoramas for design review and marketing.

An interior render sells the experience of a space in a way that finish schedules and plans cannot. By applying physically based materials, natural and artificial light, furniture, and styling to a model, we let clients and buyers judge a room on how it will actually feel to stand in. Since 2018 Powerkh has delivered 400+ BIM and VDC projects for clients across the US, UK, and Europe, and we bring that model discipline to interior CGI.

We produce photorealistic interiors for lobbies, offices, retail, restaurants, hospitality, and residential spaces, working directly from your Revit, ArchiCAD, SketchUp, or CAD models, or from 2D drawings when that is all you have. We set cameras, materials, lighting, and furnishings to your brief, using our own scene templates and QA to keep quality consistent. Interior rendering pairs with our exterior architectural rendering service, and we sign an NDA on request.

Why Choose Powerkh for Interior CGI

Rooms that feel real

Physically based materials, studied daylight, and warm artificial lighting produce interiors that read as photographs, not diagrams.

From model or drawings

We render from your Revit or CAD models, or build the interior from 2D drawings when a 3D model does not yet exist.

Styled and furnished

We add furniture, decor, and props tuned to your brand and audience so each space feels curated, occupied, and aspirational.

Hourly, pay after delivery

You get a free quote with honest hour estimates and pay only once the final interior images are delivered and approved.

Our Interior Rendering Process

  1. Brief and quote

    We review your model or drawings, references, and the interior views you need, agree resolution and deliverables, and give a free quote.

  2. Scene setup

    We import or build the interior, place cameras and furniture, and set materials and lighting to match the mood you want.

  3. Draft renders

    We share low-resolution drafts so you can direct camera, lighting, materials, and styling before final production.

  4. Final rendering

    We compute high-resolution interior stills or animations and post-process them for color, contrast, and atmosphere.

  5. Delivery and revisions

    You receive the final imagery in your required formats, with a round of revisions to fine-tune the interior results.

Software We Use

We render interiors with industry-standard visualization engines driven by geometry from your BIM and CAD models, finished with professional post-production.

FAQ

What do you need to start an interior rendering project?

A 3D model in Revit, ArchiCAD, SketchUp, 3ds Max, or a CAD format, plus references for materials, furniture, and mood, the camera views you want, and output resolution. If you only have 2D floor plans and elevations, we can build the interior model first as a separate step.

How is interior rendering different from exterior rendering?

Interior rendering focuses on rooms and enclosed spaces, where furniture, styling, and controlled artificial and natural light drive the image. Exterior rendering shows facades in context with landscaping and sky. We provide both; interior CGI pairs naturally with our exterior architectural rendering service.

Can you style and furnish the interiors?

Yes. We place furniture, decor, and props tuned to your brand, budget, and target audience so each space reads as curated and occupied. You can supply specific furniture and finishes, or we can propose styling that suits the room and the market you are selling to.

What formats do you deliver?

High-resolution still images in JPEG, PNG, or TIFF, walkthrough animations as MP4 video, and interactive 360-degree panoramas viewable in a browser or headset. We deliver at the resolution your design review or marketing needs and can supply layered files on request.

How much does interior rendering cost?

Powerkh uses hourly pricing. After reviewing your model or drawings, the number of views, and the level of styling and detail, we provide a free quote with accurate hour estimates, and you pay only after we deliver the final interior visuals.
