4. Assembly Instructions
The BDYDT Architecture Harry Castle set features micro-sized blocks, which are significantly smaller than standard building blocks (as small as 4mm x 5mm). This design allows for greater detail and realism in the final model. Assembly requires patience, focus, and careful attention to detail.

4.1. Preparation
- Clear Workspace: Ensure you have a large, clean, and well-lit surface to work on. This is crucial to prevent losing the small blocks.
- Organize Blocks: Due to the high piece count and small size, it is highly recommended to sort the blocks by color, shape, or size into separate containers before beginning assembly. The blocks are not pre-sorted or numbered in bags.
- Review Manual: Carefully read through the entire instruction manual provided with the product before starting. Familiarize yourself with the building steps and block types.
4.2. Assembly Steps
Follow the detailed, step-by-step instructions provided in the physical manual included with your set. Each step illustrates the blocks required and their placement. Pay close attention to the orientation of each piece.
- Patience is Key: This is a complex model. Take your time and do not rush. Building in short sessions can be more effective than long, tiring ones.
- Secure Connections: Ensure each block is firmly pressed into place. The high-quality plastic blocks are designed for a tight fit to maintain structural integrity.
- Double-Check: Periodically review previous steps to ensure accuracy, as errors can be difficult to correct later.

5.2. Cleaning and Maintenance
To keep your model looking its best:
- Dusting: Use a soft brush, a can of compressed air, or a microfiber cloth to gently remove dust.
- Cleaning: For more thorough cleaning, lightly dampen a cloth with water and a mild soap solution. Gently wipe the surfaces, then dry immediately with a clean, dry cloth. Avoid harsh chemicals or abrasive materials.
- Storage: If disassembling or storing, keep blocks in sealed containers to prevent loss and protect from dust.
6. Troubleshooting
6.1. Missing Pieces
While quality control is in place, occasionally a small number of pieces may be missing from a set. If you encounter missing pieces:
- Thorough Search: Double-check your workspace and packaging. Due to their micro size, blocks can easily be overlooked or stick to packaging materials.
- Contact Support: If pieces are confirmed missing, please contact BDYDT customer support with details of the missing parts (as described in the instruction manual).
6.2. Difficulty with Assembly
This set is designed to be challenging. If you find assembly difficult:
- Re-read Instructions: Review the current and preceding steps in the manual carefully. Sometimes a small detail can be missed.
- Check Orientation: Ensure blocks are oriented correctly as shown in the diagrams.
- Take a Break: Step away from the build for a while and return with fresh eyes.
- Seek Assistance: Consider building with a friend or family member, as a second pair of eyes can often spot solutions.
