Chicago North Shore area home addition costs in 2023 vary widely depending on the type and size of the addition you’re considering. Nevertheless, to give our clients a starting point for planning, we’ve assembled statistics on two of the most common types of addition projects: bathroom additions and primary suite additions.   ## **Bathroom Additions** Bathroom additions may be divided into two categories: midrange and upscale. Midrange additions, where a 6-by-8-foot bathroom is built over a crawlspace with poured concrete walls, cost an average of $58,586 and recoup $20,334, or 34.7%. This addition includes a cultured-marble vanity with a molded sink, chrome faucets, and a mirrored medicine cabinet; a 30-by-60-inch fiberglass bathtub/shower combination with ceramic tile surrounding it and a single-lever, temperature and pressure balanced faucet; a low-profile toilet; a linen storage closet or cabinet; ceramic tile flooring; general and spot lighting and electrical wiring to code; painted trim and vinyl wallpaper. Upscale bathroom additions, where a 100-square-foot primary bathroom is added onto an existing primary bedroom over a crawl space, cost an average of $107,477 and return $34,997, or 32.6%. Features include a 42-by-42-inch, neo-angle, frameless glass shower with ceramic tile walls, an accent strip, a recessed shower caddy, and body-spray fixtures; a freestanding soaker tub with high-end faucets; a compartmentalized commode with a toilet. The addition also includes a stone countertop with two sinks and two mirrored medicine cabinets with lighting; cabinetry with a custom drawer base; wall cabinets; large ceramic floor tiles; an extended HVAC system with in-floor heating; and general and spot lighting throughout.   ## **PRIMARY Suite Additions** Likewise, primary suite additions may be divided into the same categories: midrange and upscale. Midrange primary suites are considered as 24-by-16-foot spaces added over a crawlspace and are quoted at $164,649 with a cost recoup of $58,484, or 35.5%. They include a main bedroom area with carpeted flooring and painted walls, ceiling, and trim; a walk-in closet adjacent to the bedroom area; and a bathroom with a freestanding soaker tub with tile, a separate 3-by-4-foot ceramic tile shower, a double-bowl vanity with a solid-surface countertop, an exhaust fan, and general and spot lighting throughout. Upscale primary suite additions in Chicago, where a 32-by-20-foot extension is added over a crawlspace, cost an average of $339,513 and recoup $81,042, or 23.9%. The spacious sleeping area with a lounging/sitting area includes custom bookcases, built-in storage spaces with millwork details, and a high-end, gas fireplace with a stone hearth and custom mantle. Next to the bedroom is a walk-in closet/dressing area with natural light, mirrors, and linen storage. French doors are also included. The bathroom features a walk-in shower with a dual-shower system, stone walls and floor, and a custom frameless glass enclosure; a freestanding soaker bathtub; a partitioned area for a luxury, one-piece toilet; two sinks in separate custom vanities with stone countertops and large mirrors; and a 5-foot hospitality center with a bar sink, under-counter refrigerator, custom cabinetry, granite or marble countertop, and microwave.
