Tucked away on a deep, dreamy lot in Montclair's sought-after estate section, this enchanting cottage looks like it was plucked straight from the pages of a storybook. One of the most beloved homes in town, it overflows with warmth, charm, and whimsical details. With three floors of living space, there's plenty of room to make yourself at home - 3 bedrooms, 2.5 baths, family room, elegant formal living and dining rooms, and a inviting kitchen that feels like it belongs in the European countryside. Just outside you're surrounded by lush, private gardens and two stunning bluestone terraces perfect for morning coffee, evening wine, or simply soaking in the tranquility. And the big stuff? Already done. In 2017, mechanicals were updated and a whole-house generator was added - because peace of mind! And in 2024, french drains, sump pumps and new lower level flooring. The slate roof got a glow-up too, complete with copper flashing and two custom French glass awnings that take the storybook feel to the next level. Best of all, you're a quick stroll to downtown Montclair's killer food scene, museum, indie shops, performing arts spaces and movie theater.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
