The main architectural rendering styles are photorealistic, sketch, marker, ink, watercolour, pastel, stipple, clay model, flat illustration and collage. Photorealistic renders sell a finished design. The hand-drawn and illustrative styles do a different job: they keep a proposal feeling open, put atmosphere ahead of accuracy, or give a practice a recognisable visual identity.

This guide shows all ten on real architectural imagery, with notes on when each style works and how to produce it. Every example here was made in Fenestra, either with a built-in style or a short prompt, starting from the same kind of image you already have: a render, a 3D model view or a sketch.

If you want the one-line version: match the style to the stage of the project. Loose styles early, when you want feedback. Resolved styles late, when you want sign-off.

1. Photorealistic

The default, and still the style clients ask for by name. Accurate materials, physically plausible lighting, believable context, with studios like Mir setting the benchmark for how atmospheric the style can get. A photorealistic render answers the question "what will it actually look like?", which makes it the right choice for planning submissions, marketing imagery and final client presentations.

Its weakness is that it closes conversations. Present a photoreal image of a half-decided scheme and clients respond to the sofa fabric, not the massing.

In Fenestra this is the core Generate workflow, from a sketch, a model view or an earlier render.

2. Loose pencil sketch

The opposite end of the spectrum. A pencil study reads as thinking-in-progress, which is exactly why it works in early client meetings: people feel invited to comment on a drawing in a way they never do with a polished render. We wrote about this effect in why not every image should look finished.

Loose Pencil is one of Fenestra's built-in drawing styles, so you can take an existing render backwards into a sketch. Going from render to pencil sounds backwards until you try it in a design review.

3. Marker

Bold linework with broad colour fills, straight out of the pre-digital presentation tradition. Marker renders feel confident and graphic, and they survive being printed small or viewed on a phone, which makes them a favourite for competition boards and social posts. For houses and small residential work, marker is often the friendliest style: warm enough for a homeowner, precise enough for a planner.

Marker is a built-in Fenestra style.

4. Ink

Line-driven images with strong contrast and visible gesture. Ink covers a range: light and exploratory at one end, high-energy and expressive at the other. It suits urban scenes, facade studies and anything where the geometry itself is the story.

Fenestra ships three ink variants as built-in styles: Loose Ink for quick exploratory drawings, Expressive Ink for contrast and movement, and Muted Ink for a calmer, more restrained read.

5. Watercolour

Soft washes, bleeding edges, plenty of white paper. Watercolour has been the language of architectural presentation for two centuries and it still signals craft. It flatters landscape and heritage projects especially, where a photoreal render can feel cold.

Watercolor is part of Fenestra's style library, or you can steer your own version with a prompt in Edit:

Convert this render into a loose architectural watercolour. Soft washes, bleeding edges, white paper background, light pencil linework showing through. Keep the composition and proportions exact.

6. Pastel and crayon

Texture and warmth. Pastel gives soft colour and atmosphere; crayon adds roughness and a playful quality that suits conceptual and community-facing work, the kind of imagery you would put in a public consultation rather than a boardroom. Of all the interior design rendering styles, pastel is the most forgiving: it flatters fabrics, soft furnishings and daylight in a way harder line styles can't.

Pastels and Crayon are both built-in styles.

7. Stipple

Images built from fine dots and texture, influenced by printmaking and traditional architectural illustration. Stipple is slower to read than line styles, which is part of its appeal: it rewards a closer look. Strong choice for monochrome portfolio pieces and editorial-feeling imagery.

Stipple is a built-in style.

8. Clay model

Everything rendered as if cast in white or grey material, with soft studio lighting. Clay renders strip out materials entirely so the conversation stays on form, massing and light. Architects use them mid-design for exactly that reason, and they have become a portfolio style in their own right.

Prompt for it in Edit (this pair was made with Flux 2 Pro):

Turn this into a white clay model render. All surfaces matte white, soft studio lighting, subtle ambient shadows, no materials or colour, plain light grey background.

9. Flat illustration

Simplified shapes, flat colour, minimal shading, the style you see in architectural journals and diagrams. Flat illustration is doing well on social media right now because it reads instantly at feed size. It also pairs naturally with diagrams and analytical drawings.

Illustration and Concept Sketch live in the style library, or prompt for a specific look:

Convert this image into a flat architectural illustration. Simplified geometry, flat colour fills, minimal shading, clean vector-like edges, limited palette of 5 colours.

The prompt applied to an interior photo, again with Flux 2 Pro:

Concept Sketch sits between illustration and ink. The same photo again:

We covered this territory in more depth in AI illustration for architecture and interiors.

10. Collage

The OMA-and-Fala-Atelier look: photographic textures and cut-out people layered over simple geometry, deliberately imperfect. Collage signals a design-led practice and gives you licence to be atmospheric rather than accurate. It divides clients more than any other style on this list, which is arguably the point.

Turn this render into an architectural collage. Flat photographic textures, cut-out style people and trees, slightly misaligned layers, muted colours, visible paper texture.

Choosing a style

A rough mapping that holds up in practice:

• First client meeting: pencil, loose ink, crayon
• Design development: clay, marker, muted ink
• Public consultation: watercolour, pastel, flat illustration
• Final presentation: photorealistic, collage
• Portfolio and social: stipple, flat illustration, collage

The bigger opportunity is consistency. Pick two or three styles and use them everywhere, and the style itself becomes part of how clients recognise your work. That was the thinking behind Fenestra's drawing styles collection: renders that represent you, not a house style borrowed from someone else's portfolio.

Rendering style questions, answered

What are the different types of rendering styles? They fall into three groups: photorealistic styles that simulate real materials and light, hand-drawn styles (pencil, ink, marker, watercolour, pastel, stipple) and graphic styles (clay, flat illustration, collage). The ten above cover the ones you'll actually see in practice.

Are 3D rendering styles a separate thing? No. Any of these styles can start from a 3D model view, a finished render or a sketch; the style describes the output, not the input. A raw SketchUp or Revit screenshot takes a marker or watercolour style just as well as a polished render does.

Can you change rendering styles in Enscape, Lumion or Twinmotion? Only within each engine's preset list: Enscape has a white-model and outline mode, Lumion and Twinmotion ship a handful of artistic effects. The presets are fixed per release. Prompt-based styling has no fixed list, and it works on screenshots exported from any of these tools.

Which rendering style is best for houses? For homeowners, photorealistic or watercolour; both read as "my actual house". For planning submissions, photorealistic with accurate context. For early residential concepts, loose pencil or marker keeps the conversation about the design rather than the finishes.

Trying them on your own project

Any of these styles can be applied to an image you already have. Upload a render, a model screenshot or a sketch, then either pick from the style library (Marker, Crayon, Loose Ink, Pastels, Expressive Ink, Muted Ink, Stipple, Loose Pencil, Watercolor, Illustration and more) or describe the style you want in Edit. The composition stays yours; the rendering style changes.
