In this newsletter, I’ll show how developers and real estate professionals can use ChatGPT to accelerate the site research process. When I worked at Brookfield Properties, we spent significant time researching data about potential and acquired sites as part of our internal Development Option Analysis process.

Site analysis was a fundamental step that mapped out key information about a location for both internal and external communication. Fifteen years ago, this process was entirely manual (mostly done by me!). Research was the most time-consuming aspect, involving reviews of local planning regulations, heritage maps, key planning consents, and zoning plans. We then had to package this information so it could be easily communicated.

Now, with ChatGPT, the site research process can be fully automated with a GPT assistant. My goal in this article is to demonstrate how easy it is to create your own Custom GPT using site analysis as an example. Believe it or not, this Site Research Assistant can reduce hours of work to just five minutes.

This newsletter will answer the following questions:

1. What are the 3 key benefits of using a Custom GPT for site research?

2. How can you build your own Site Research GPT (step-by-step guide, no coding needed)?

3. What lessons have been learned from using a GPT, and what can be improved?

Let’s dive in.

1. What Are the 3 Key Benefits of Using a Custom GPT for Site Research?

Creating a Custom GPT for automating site research is particularly useful if this is a task you perform repeatedly. Mapping out key information about a site helps create a mental image of its potential. However, conducting research manually is time-consuming and takes away from time that could be spent brainstorming development ideas.

Based on my experience, here are the three main benefits of using ChatGPT for site analysis:

1. Speed – The GPT accelerates research, providing a complete set of key site data within minutes.

2. Preparation – It helps you get ready for site visits by offering deeper insights into a location, accessible via smartphone on the go.

3. Report Generation – The research is delivered in a ready-to-use report format, perfect for presentation decks or sharing with your team.

Using a Custom GPT allows you to analyse 10 times more sites in an hour compared to manual research.

Given its accessibility, prestigious surroundings, and skyline potential, a high-rise office, luxury hotel, or flagship retail space would be the best development options. Future design should prioritize sustainability, views, and seamless integration with the City’s evolving urban fabric.

2. How to Build Your Own Site Research GPT (Step-by-Step Guide, No Coding Needed)

Creating a Custom GPT is simple and takes just a few minutes. Think of Custom GPTs as “mini-applications” within your ChatGPT account. These GPTs retain a set of custom instructions that you can use repeatedly without having to rewrite long prompts.

My Objective When Creating a Site Research GPT:

1. The ability to upload a Google Earth image with a site markup.

2. A GPT-generated Site Analysis Report highlighting key location data.

Step-by-Step Process to Create a Custom GPT:

1. Access GPT Creation – Inside the GPT section of ChatGPT, select “Create a GPT.”

2. Define Your GPT’s Purpose – In the “Create” tab, describe what you need the GPT to do. For example:

Hey ChatGPT, I need help creating a GPT to research facts and information about locations marked on a Google Earth image.
I would like the GPT to output an analysis of the location in a report format including:

- Distances from transport connections.
- Distance to important landmarks.
- Sun path in relation to the site.
- Major roads.
- Key pedestrian routes.

1. Upload Background Information – If necessary, provide relevant documents in the “General Knowledge” section, such as:

   • Planning legislation

   • Building regulations

   • Climate/environmental data

   • Demographic reports

   • Any region-specific information

2. Test and Refine – Run tests to ensure the GPT delivers quality responses. Adjust prompts and inputs as needed.

3. Deploy and Use – Once satisfied, your GPT is ready for use. The more you use it, the better you’ll understand how to refine it further.

3. Lessons Learned from Using a Custom GPT and What Can Be Improved

After using ChatGPT intensively for the past 14 months and creating multiple Custom GPTs (including this one), here are some key takeaways:

Lessons Learned:

1. Treat the GPT as an assistant – It enhances efficiency but still requires human oversight.

2. Garbage in, garbage out – The quality of output depends on well-structured input.

3. Always verify responses – Cross-check results for accuracy.

4. Beware of AI “hallucinations” – The GPT may sound confident even when incorrect.

5. Geographic limitations exist – The same Site Analysis GPT may not perform well across all regions.

Areas for Improvement:

1. Create region-specific GPTs – Developing dedicated Site Analysis GPTs for different regions or cities will enhance accuracy.

2. Refine knowledge files – Uploading detailed regional data ensures the GPT delivers more precise results.

3. Improve report formatting – Adjust GPT instructions so the generated report is 90% presentation-ready.

Conclusion

Custom GPTs are a game changer when applied to micro-tasks that occur repeatedly in a workflow. They are flexible tools that can be continually refined for better performance.

Key Takeaways:

1. ChatGPT makes site research and analysis significantly faster – Time saved can be reinvested in brainstorming development ideas.

2. Custom GPTs automate site research – They function as reusable mini-apps.

3. You can generate a Site Analysis Report in minutes – Delivering a 90% presentation-ready draft.

4. Always review GPT outputs – AI-generated responses should not be blindly trusted.

Today, we used site analysis as an example. However, GPTs can be applied to many other repetitive micro-tasks, such as:

• Reviewing legal documents

• Drafting scopes of work

• Writing investment memos

• Summarising key actions from a video call

By leveraging Custom GPTs, you can automate repetitive tasks and focus your energy on high-value strategic decisions.
