Master suite addition (upscale)
Average cost: $271,470
Return on investment: 50.4%
The worst home renovation project for your money also is the most expensive. This upscale master suite addition costs more than double the midrange master suite we described.
Why so much? For one thing, adding square footage typically is an expensive proposition, and this project adds a 32-by-20-foot master bedroom, lounge area and large, adjacent master bath to the home’s footprint.
Also, the details are deluxe. The sleeping space has custom bookcases and built-in storage, a high-end gas fireplace with a stone hearth and custom mantel. The dedicated walk-in closet and dressing area have mirrors and linen storage.
A dream bathroom has a dual shower with stone floor and walls and in-floor heating and a 5-foot-long hospitality center with bar sink, under-counter fridge, custom cabinets, a microwave and stone countertop.
The estimated return upon resale: $136,820 — about half of what you’d have put into it.
