Frequently Asked Questions

Does accessible design look institutional?

Not at all. Modern universal design is seamless and attractive. Features like curbless showers and lever handles are stylish mainstream choices.

Can I add accessibility features later?

Yes, but at 10-20x the cost of including during construction. Plan basic infrastructure (wider doors, wall blocking, single-level) now and add features as needed.

Is single-story less economical?

For smaller homes under 100m², single-story is often more economical—simpler structure, no stairs. Larger homes may require two stories for compact footprint.

What about resale value?

Accessible homes appeal to larger buyer pool: aging buyers, families with elderly parents, anyone valuing convenience. Growing demographic advantage.

Do I need to follow specific standards?

Residential homes in Bulgaria don’t require accessibility standards, but following international guidelines (like ISO or ADA concepts) ensures practical functionality.
