Thank you for using ActiveReports. Yes, this is possible, but we need more information about your report and your data structure to recommend a solution. Please contact our support team at www.grapecity.com and include as much detail about your report design and the datasource and the team will be able to help you.
If I understood your case correctly, you can either group the data by Building and the group header would contain Building information and the detail would have building details. Or you can place a List bound to Building and within the List you can have a Table for the Building details. Again, not exactly sure, it depends on your layout and data.
Also, feel free to reach to our forums or submit a ticket if you would like assistance from the GrapeCity Support team.
