Own a documented piece of State College's architectural history. Known as the Mateer House & featured in Penn State University Libraries' Central Pennsylvania Architecture Collection, this distinctive mid-century residence was designed by noted architect & longtime Penn State professor Philip F. Hallock. Signature elements of Hallock's design remain beautifully evident throughout, from the projecting gables & contrasting brickwork to geometric detailing & thoughtfully placed windows that create privacy while giving the residence its unmistakable architectural rhythm. Set on a .55-acre corner lot within the Borough, this is a home with a story to tell, one that has remained part of the local landscape for generations. An attached 2-car garage, natural gas forced-air heat, central air, a new roof in 2025 & new downspouts in 2026 bring everyday comfort & convenience while preserving the distinctive character of its mid-century design. Step inside & the warmth of its mid-century roots immediately takes over. Parquet wood flooring flows through the main living areas, where rich wood tones, brick accents & expansive windows showcase the home's original architectural character. The spacious living room is anchored by a striking brick fireplace framed by warm wood detailing, creating a natural gathering place for quiet evenings, lively conversations or cozy fall weekends after a day in Happy Valley. The adjoining dining room continues the easy flow, while the 12' x 12' butler's pantry adds an unexpected layer of storage & functionality. Nearby, the kitchen stays true to its mid-century character with warm wood cabinetry, parquet flooring, breakfast bar & included appliances. The primary bedroom features oak hardwood flooring, a walk-in closet & a beautifully remodeled private full bathroom where sleek modern finishes complement the home's warm wood tones. Tile flooring, oversized granite-topped vanity & an impressive glass-enclosed walk-in tile shower with rainfall showerhead create a standout retreat. The additional bedroom also features oak hardwood flooring & offers wonderful flexibility as a comfortable space for visiting guests or a dedicated home office. A second remodeled full bathroom with ceramic tile flooring & a tub with custom tile surround completes the main level. Downstairs, the finished 23' x 11' family room provides even more space to gather, relax, watch the game or simply spread out, while the unfinished portion of the lower level houses the laundry area & offers additional storage. Outside, the architecture makes just as much of an impression. Brick walls, geometric detailing & projecting rooflines give the Mateer House its distinctive mid-century profile, while mature trees & established landscaping surround the property with a wonderfully tucked-away feel. A spacious stone patio provides an inviting outdoor living area, while the screened porch offers another place to slow down & enjoy the surroundings. This combination of space, convenience & architectural character is becoming increasingly difficult to find within State College. Adding another layer of opportunity, the property includes an active rental permit. The appliances, washer, dryer & most personal property will convey with the sale (excluding items displayed on the basement walls & the living-room rug), making this an especially intriguing possibility for a furnished Happy Valley weekend retreat, investment property or full-time residence. For those drawn to distinctive architecture, local history & authentic mid-century design, the Mateer House presents a rare opportunity to own a home that is truly unlike anything else. Now imagine making it the backdrop for your own traditions, Penn State weekends, family gatherings & memories still waiting to be made.
