About
Marshallton Heights is a detached single-family subdivision in the unincorporated Marshallton area of New Castle County, approximately five miles west of downtown Wilmington on the Kirkwood Highway corridor. The subdivision sits within the broader Marshallton community — an area founded in 1836 along Red Clay Creek and named for mill owner John Marshall — and its residential build-out occurred primarily in the 1950s and 1960s, part of the mid-century suburban expansion documented across the Marshallton neighborhood where 90.1% of homes date to the 1940–1969 era. County parcel records formally identify individual properties under the subdivision name ‘MARSHALLTON HEIGHTS’ with NC5 zoning, and listed homes have ranged from approximately 622 to 1,925 sq ft of living space. The subdivision feeds into the Red Clay Consolidated School District, with Thomas McKean High School located at 301 McKennan’s Church Road within the same 19808 ZIP code.

What Makes This Distinct
