515 NEW CASTLE STREET EXTENSION, REHOBOTH BEACH, DE 19971

$1,850,000

This boutique, coastal-chic residence, affectionately named "Cedar House" is the crafted outcome of a 2017 complete architectural reinvention from its original bones to its beautifully finished form today. Positioned in a prized location just 5 blocks to the ocean and approximately 10 minute walk to Rehoboth Avenue in a quiet,… Read More residential tree lined neighborhood. Inside, the home's airy open floor plan lives spaciously within its 1,300 square feet, reflecting an unparalleled attention to authenticity and detail. Upon entering, you're greeted by the warmth of wide-plank heart-pine floors, tongue-and-groove wood walls, and reclaimed hand-hewn oak beams - materials that lend character and texture befitting a quintessential beach home. The living room features a coffered ceiling and a 19th-century fireplace mantle, creating a bespoke focal point. The custom kitchen was designed with no expense spared: Dramatic 3-inch profile Carrara marble countertops and full marble blackspash, custom cabinetry, and built-in Thermador stainless-steel appliances. A whimsical circular interior window provides a delightful connection to the sun-drenched sunroom along the home's western side. Two private primary bedrooms with en-suite baths complete the main level; one suite's bath also functions conveniently as a powder room. The exterior highlights old-world craftsmanship, including natural cedar shake siding and roofing, oversized copper gutters and downspouts, large Marvin casement windows, and custom wood doors. Mature and meticulously maintained landscaping frames the entire property - including formal boxwood hedging, hydrangeas, magnolia and a raised-bed garden - while an authentic Belgian block driveway winds back to a distinguished carriage house garage. (Professionally designed renderings for a carriage house conversion with pool & gas fire pit addition are available from the seller.) A perfect offering for the discerning, design-minded buyer, this residence stands apart from other homes available at this price point for its uncompromising craftsmanship, curated materials, refined coastal aesthetic, and highly coveted in-town Rehoboth Beach location. *NOTE: Property has dedicated well for lawn/ garden irrigation and electric car charger. *ALSO: Just over 1 block to the much loved local footbridge "Turtle Bridge" that traverses Silver Lake and short walk to the beach. (*Public designated pickleball & tennis courts just a block away, as well.) Read Less
