Experiments with AI - 02 - Prompt sample to render/edit images

 This is a continuation of the post: <<previous>>

Prompt to Chatgpt: 

I want you to refine the prompt below so that copilot can create a view of a residential tower: I want you to render a residential tower. The tower has 5 podium levels of parking, 1 level of fully glazed clubhouse level and 26 levels of residential units above. The footprint of the building is like a rectangle of dimension 100m by 80m. The floor to floor height of the is 3.3m. The total height of the building is 106m. The podium paking levels should have partial glass and openings with interesting patterns. The clubhouse level should be fully glazed and should act as a break between residential floors and the podium floors. The residential units should have partial curtain wall, partial jaisalmer stone cladding, balconies need to be arranged interestingly. The building should have plants sparingly to create interest. The ambience of the view should be dusk with lights in some of the residential units turned on. If you need any other info to create the view, please ask one by one. 



Prompt given by Chatgpt:

This is already a strong prompt. However, it reads more like an architectural specification than a prompt for an image generation model. Firefly (and Gemini) generally produce better results when the prompt is prioritized, descriptive, and less constrained by numbers. The most important visual features should appear first, while technical details should support the description.

Here's how I would rewrite it:


Create a photorealistic architectural visualization of an iconic 110-metre luxury residential tower in a refined tropical-modern architectural style. The design should be elegant, timeless, and premium, comparable to award-winning residential towers by WOHA, Kerry Hill Architects, DP Architects, and SCDA. The architecture should emphasize clean geometry, refined proportions, rich materiality, and sophisticated façade articulation rather than futuristic forms.

Overall Composition

The tower should be expressed as three clearly identifiable architectural zones:

  • Five-level luxury parking podium

  • One double-height, fully glazed clubhouse sky lobby

  • Twenty-six residential levels above

The total height is approximately 110 metres. The residential floor-to-floor height is 3.3 metres, while the clubhouse is 6.6 metres high, creating a dramatic architectural transition between the podium and tower.

The building has a broad rectangular footprint of approximately 100 × 80 metres, giving it a confident, elegant presence.


Podium

Design the podium as a luxury architectural feature rather than a parking garage.

Include:

  • Sculptural perforated façade screens

  • Large geometric openings with varied patterns

  • Deep reveals creating dramatic shadows

  • Partial glazing revealing glimpses of parking behind elegant screening

  • Integrated warm architectural lighting

  • Bronze-toned metal fins and textured panels

  • A premium residential arrival experience

The podium should appear solid, sophisticated and beautifully crafted.


Clubhouse Sky Lobby

Create a striking double-height glazed clubhouse that acts as a luminous architectural break between the podium and residential tower.

Features include:

  • Floor-to-ceiling curtain wall glazing

  • Warm interior lighting

  • Visible luxury amenities

  • Floating lantern appearance

  • Transparent and elegant expression

  • Strong horizontal emphasis

This level should become the visual highlight of the building.


Residential Tower

The residential tower should feel luxurious, calm and highly livable.

Primary materials include:

  • Warm golden Jaisalmer sandstone cladding

  • High-performance low-E curtain wall glazing

  • Champagne bronze aluminium framing

  • Dark metallic architectural accents

The façade should use alternating stone and glass surfaces to create warmth and refinement.

Balconies

Avoid repetitive stacked balconies.

Instead create:

  • Staggered balcony compositions

  • Alternating projections and recesses

  • Deep shadows

  • Elegant rhythm

  • Strong façade depth

  • Carefully balanced asymmetry

The façade should feel dynamic without appearing chaotic.


Landscaping

Use restrained tropical landscaping.

Include only:

  • Selected balcony planters

  • Podium-level planting

  • Small rooftop gardens

  • Elegant entrance landscape

Avoid a "vertical forest" appearance.

Architecture should remain the dominant visual element.


Lighting

Time of day: Blue-hour dusk

Create a warm, luxurious atmosphere with:

  • Approximately one-third of apartments illuminated

  • Brightly glowing clubhouse

  • Warm façade lighting integrated into the podium

  • Soft reflections on glass

  • Warm street lighting

  • Rich contrast between interior and exterior lighting

The building should feel inhabited, welcoming and exclusive.


Camera

  • Dramatic three-quarter corner view

  • Camera approximately 25 metres above ground

  • Entire building visible

  • Slight upward perspective

  • Two façades clearly visible

  • Strong composition suitable for the cover of an international architecture magazine


Context

Place the tower within a premium urban residential district.

Include:

  • Wide tree-lined boulevard

  • Luxury drop-off court

  • High-quality paving

  • Contemporary street lighting

  • A few luxury cars

  • Small groups of residents

  • Clean public realm

Keep surrounding buildings low and understated so the tower remains the focal point.


Rendering Style

Ultra-photorealistic architectural visualization

  • International architectural competition quality

  • Luxury real-estate marketing image

  • Physically based rendering (PBR)

  • Natural colours

  • Accurate materials

  • Crisp detailing

  • Cinematic lighting

  • Realistic reflections

  • Soft atmospheric depth

  • 8K quality

  • Highly refined architectural photography aesthetic


Keywords

Luxury residential tower, tropical modern architecture, Singapore condominium, Jaisalmer sandstone, curtain wall glazing, staggered balconies, architectural visualization, premium materials, blue hour, cinematic lighting, elegant façade, timeless architecture, sophisticated detailing, contemporary high-rise, luxury real estate.


Negative Prompt

Cartoon, anime, futuristic sci-fi, parametric architecture, twisting tower, excessive greenery, vertical forest, repetitive balconies, exposed parking decks, cluttered façade, heavy ornamentation, low-resolution textures, flat lighting, exaggerated HDR, oversaturated colours, distorted proportions, unrealistic reflections, fog, rain, construction site, cranes, text, logos, watermark.

Using AI to produce rendered Views - My experiments with AI - 01

 Our trials with AI rendering are outlined below. There must be better ways of doing this 

  1. Created a descriptive para of the building:

    1. footprint dimension, no of podium, clubhouse floor, no of residential floors, etc.; floor to floor height

    2. A note about the building massing - glazing proportion, stone cladding and balcony arrangement; greenery/plants on the elevation

    3. Ambience of the view/lights

    4. Instruct the AI to ask for any needed additional details.  

  2. Post this in chatgpt and ask it to create a proper prompt for Co-pilot

    1. ChatGPT details the prompt - including the type of architectural style to follow, etc. 

  3. Post the prompt back in Co-pilot

First Trial: 

This is the rendering we got in Gemini AI without any plans, but with only descriptions. We prompted podium floors + infinity pool + landscape. However, Gemini AI didnt create the requested number of floors for some reason. After the production of the first rendering, Gemini could not understand our prompts to increase the number of floors. Apparently, as of today, Gemini AI is not image aware. 

Since then the architects changed the footprint of the proposed building to a proper rectangle (instead of the L shape)

*****Please note that Gemini AI is not allowed to be used with BEPL data per our IT policy -  for privacy + copyright + intellectual property reasons. ****

Second Trial: 

The view was dark. Again, Gemini AI could not add 10 more floors. We could not use the image. Gemini AI didnt work out. 


Third try: 

By this time the architects had shared the following rendered image: 

We didn't like the view. The sky was not good and there wasnt much sciography effects. 

We uploaded this rendering into copilot (Approved AI to be used within BEPL). It cleaned up the sky and the lighting and produced the image below. 





Copilot was also able to add floors and cleanup the Gemini AI produced image: 

Copilot also gave us options, as below:

Points to note: 

  1. Co-pilot adds and reduces the number of floors without any issues. 

  2. If we already have a rendering from the architect, we can upload it and ask it to tweak it. 

  3. Copilot takes around 5 mins to create the first image. 

  4. Free version of the Copilot allows only 4 tweaks per day. (This is a big impediment.)

  5. AI is a fast changing field and new softwares that work better may be launched any time.

I will share the actual prompt and the prompt created by chatgpt in the next post.

AI - Band wagon - Prompts

Most of us use ChatGPT, Copilot, Gemini, etc. with simple (vanilla) questions and prompts. However, the quality of the output depends heavily on how we ask the question. A well-crafted prompt can often produce results that are significantly better, more detailed, and more useful.
