Designing an apartment building for disabled or persons with special needs can be a challenging task, but it is important to ensure that the building is accessible and comfortable for all residents. Here are some tips to keep in mind when designing an apartment building for disabled or persons with special needs:

1. Wide doorways and hallways: Make sure doorways and hallways are wide enough to accommodate wheelchairs, walkers, and other mobility devices. This will make it easier for residents to move around the building.
2. Elevators and ramps: Include an elevator and ramps to make it easy for residents who use wheelchairs or other mobility devices to access all floors of the building.
3. Grab bars and handrails: Install grab bars and handrails in bathrooms and near stairways to provide added support and stability for residents with mobility issues.
4. Accessible appliances and fixtures: Choose appliances and fixtures that are easy to use for residents with mobility or dexterity issues. For example, lever-style faucets are easier to use than knobs.
5. Lighting: Good lighting is essential for residents with visual impairments. Make sure to include ample lighting in common areas, hallways, and apartments.
6. Soundproofing: It is important to consider soundproofing in the design of the building in order to minimize noise levels and ensure a comfortable living environment for all residents, especially those with hearing impairments.
7. Supportive Community: Building a sense of community among the residents with special needs is important. This can be achieved through common areas, organized events, and shared spaces.

By keeping these tips in mind, you can design an apartment building that is accessible and comfortable for all residents, including those with special needs.
