About
Riddlewood is a mid-century single-family subdivision in Middletown Township, Delaware County, built between approximately 1953 and the late 1950s on 218 acres purchased from the estate of racehorse owner Samuel D. Riddle — the man behind Man o’ War and Triple Crown winner War Admiral. Developer Arters Brothers, working with architect George Hay, planned 230 homes across a 190-acre portion of the tract; the community was recognized in 1954 by the National Association of Home Builders as one of the ten finest home developments in the United States, and was featured multiple times in Better Homes and Gardens magazine. Streets carry the names of Riddle’s most celebrated horses — Man O’ War Drive, War Admiral Lane, War Trophy Lane, Soldier Song Lane, and others — and the Riddlewood Swim Club, a non-profit member-owned pool at 56 War Trophy Lane, has operated continuously since 1957 alongside a ball field and basketball and volleyball facilities on community-retained land.

What Makes This Distinct

Worth Asking
Have you considered that Riddlewood’s lack of a mandatory HOA means no recorded covenants are uniformly enforced — so the condition of neighboring lots, fencing, additions, and outbuildings may vary significantly from street to street, and a buyer’s due diligence should include a direct review of any deed restrictions attached to the specific parcel rather than assuming community-wide rules apply?
Common Questions
What is the history behind Riddlewood’s street names?
The subdivision was built on land purchased from the estate of Samuel D. Riddle (1861–1951), a Delaware County textile businessman and racehorse owner whose most famous horses included Man o’ War and Triple Crown winner War Admiral. After Riddle’s death in 1951, Arters Brothers acquired 218 acres of the estate and, along with architect George Hay, developed the community in the 1950s. Each street was named after one of Riddle’s celebrated racehorses: Man O’ War Drive, War Admiral Lane, War Trophy Lane, Soldier Song Lane, Whirlaway Road, Rampart East, Rampart West, and Anamosa, among others. Riddle’s remaining estate funded Riddle Memorial Hospital, which opened in 1963 on Baltimore Pike adjacent to the subdivision.
Is there a community pool in Riddlewood, and is it open to non-residents?
Yes. Riddlewood Swim Club, located at 56 War Trophy Lane in Middletown Township, has operated as a non-profit, non-exclusive membership pool since 1957. Membership is not restricted to Riddlewood residents — households from Media, Lenni, Aston, and surrounding areas may join. The club operates on a bond-and-dues model; members hold part-ownership in the facility. Day-guest access is also available through member guest passes. The site also includes basketball, volleyball, and baseball facilities on community-retained land.

Based on public records for this ZIP code and address range, Riddlewood children most commonly attend Glenwood Elementary School (122 South Pennell Road, Media, PA 19063), which is located in Middletown Township and serves grades K–5 within the Rose Tree Media School District. Students then typically advance to Springton Lake Middle School (grades 6–8) and Penncrest High School (grades 9–12).

Items to Verify with Your Agent
A few specifics on this page are sourced from secondary aggregators or older filings. Confirm before relying:
- Hoa Name — No formal HOA has been identified in public records or public filings. The Riddlewood-Sunnybrae Community Association (RSCA) is a voluntary civic association, not a deed-based HOA with mandatory dues or recorded covenants. Buyers should confirm through a title search whether any deed restrictions run with specific parcels.
- Approx Homes — The RSCA history page states Arters Brothers originally planned 230 homes on 190 of the 218 acres. This figure reflects the original development plan, not a verified parcel count from Delaware County assessment records. Actual built count may differ due to lot splits, infill, or plan amendments. Tier set to ‘estimated’.
- Interior Sqft Range Text — Square footage figures are drawn from individual address records on Spokeo and PeopleFinders (public record aggregators) and one Homes.com listing, not from a uniform assessor dataset. The range (approx. 1,032–2,280 sq ft) is directionally consistent across sources but should be confirmed against Delaware County assessment data for any specific parcel.
