Listing description

506 Trinity Place is a beautifully constructed 3 story stone home located on a quiet street in the Ambler section of Upper Dublin. This special block is comprised of 4 magnificent turn of the century homes built for the supervisors of Keasbey & Mattison Company. To own one is to own an important piece of local history. The home was built in 1900 & true to the era, it boasts spectacular details, including period trim & molding, beautiful turned staircase w/ original Chestnut balusters & newel posts, deep windowsills, hardwood flooring, 9’ ceilings, solid wood 5 panel doors, & more. These timeless details would cost a fortune today. Beautiful sycamore & magnolia trees welcome you, offering a lovely view from the stately wrap around porch. The original front door w/ transom above opens into a spacious parlor boasting a swoon worthy window seat & gorgeous staircase w/ stained glass window. Through a set of pocket doors you’ll find a spacious living room which is part of a 2 story canted bay design bringing in tons of natural light. This room also features a gas fireplace w/ Mercer tile surround. Through the living room, the dining room features corner built-ins & pass through to the kitchen. Next is the den, which originally served as the kitchen, but now offers a nice space to relax. The den allows access to the 2nd floor, via a rear staircase, & the kitchen. The kitchen is fully functional, but if one were to renovate, the amount of space in this house allows for fantastic options. There is access to the rear patio from the kitchen. The 2nd floor offers 3 bedrooms (plus) & full bath. The primary bedroom sits above the living room boasting the same semi-octagonal shape. The main bedroom is accessed through a large room, great as an office or sitting room. The 2 other bedrooms are nicely sized & the amount of space on this floor allows for many possibilities. The 3rd floor offers another bedroom, a large rec room/studio/office, a craft room, full bath & small bonus room/storage area. This floor would ideal for an in law, au pair, long term guest; it would also make a fabulous primary suite. Laundry could be added on the 2nd or 3rd floor. The basement offers tons of storage, full bath, workshop area & access to the rear yard. Outside, there is a patio off of the kitchen, perfect for grilling. The pool has not been opened in 2 years, but was enjoyed prior. The driveway offers parking for 2 cars & there is plenty of parking out front. While 506 Trinity offers incredible character & construction, the home needs work & updating, making it ideally suited for someone who has the ability to put in the time & money that she deserves. The location cannot be beat. Pickering Field is 1 block away w/ a playground, basketball courts, baseball/soccer fields & concession stand during baseball season! 3 blocks away is Knights Park w/ a larger playground, open space, skate park & Ambler Community Garden. 2 blocks beyond that, is access to the Green Ribbon Trail, a 12+ mile trail meandering through multiple municipalities along the Wissahickon Creek. If you are a nature lover, access to this treasure is invaluable. It gets better! Downtown Ambler is less than .5 mile away offering fabulous restaurants & breweries, great shops, movie theater & playhouse, seasonal farmers market, year-round festivals & the best community grocery store. The train is within walking distance & access to 309 & major routes of transportation are minutes away by car. This home affords sought after Upper Dublin Schools, located within the boundaries of Fort Washington Elementary. A home of this stature, on a picturesque street, within walking distance to all that your heart can desire does not come along very often. This is an incredible opportunity to own a piece of history, yet be able to put your own personal stamp on it. If you appreciate the detail & craftsmanship of the early 1900s & the VERY special town of Ambler, do not let this one slip away.

The default rate is the average 30-year rate as of July 2026; insurance is estimated at 0.35% of the price per year. Below 20% down, lenders usually add mortgage insurance, which this estimate doesn't include. Estimate only; verify before relying on it.
