The 1903 Renaissance Revival mansion at 1300 Mount Curve sits on nearly an acre at the highest point in Minneapolis.

The Charles J. Martin House, completed in 1903 in the Renaissance Revival style, is one of the best-preserved examples of an early-twentieth-century urban estate anywhere in the city. The mansion and its grounds occupy almost a full acre at 1300 Mount Curve Avenue, and the property is listed on the National Register of Historic Places.
The house is enormous by any measure, with roughly 14,300 square feet of floor space, ten bedrooms, eleven bathrooms and the kind of richly detailed living and dining rooms that the milling fortunes of the era could pay for. A gracious foyer and library anchor the main floor.
When the house came onto the market a few years ago for the first time in some thirty-five years, it carried an asking price in the millions, a reflection both of its scale and of its place at the literal high point of the neighborhood.
The Martin House occupies what is generally cited as the highest point in Minneapolis, a siting that was no accident. The families who built on Mount Curve wanted the view, the air and the prominence that came with the ridge.
Preservationists prize the house precisely because so little has been stripped from it. Where many estates of its era were carved into apartments or lost their outbuildings, the Martin House retains the integrity that earned it landmark status.
A well-preserved example of an early-20th-century urban estate, listed on the National Register since 1978.
The Charles J. Martin House at 1300 Mount Curve Avenue, designed by the prominent Minneapolis architect William Channing Whitney and built in 1903 in the Renaissance Revival style, was added to the National Register of Historic Places on April 26, 1978, and is a designated city landmark. At roughly 14,000 square feet on nearly an acre, it is the most-cited example of the early-1900s 'city estates' that gave the hill its character.
It was built for Charles J. Martin, an executive in the milling and insurance world whose fortune was typical of the families who claimed the ridge. The semicircular drive, the ornamental wrought-iron fence and the double set of gates that historians describe were as much a statement of arrival as the house itself.

The Martin House has changed hands rarely — it came to market only a handful of times in the past century, most recently listed in the multimillion-dollar range — and each sale has drawn citywide attention precisely because so few houses of its scale survive intact. Preservation groups such as the Healy Project have used open houses there to make the case that Lowry Hill's grand interiors are worth protecting, not just its facades.
For neighbors, the house functions as a kind of anchor. It sits at the hill's high ground, it is visible from the parkways below, and it sets the standard against which the rest of the avenue is measured.
Because so few estates of this scale survive, the Martin House functions as a public landmark even though it is a private home. Its rare appearances on the market draw citywide coverage, and preservation groups have used access to it to argue that Lowry Hill's interiors, not just its facades, are worth protecting.
City landmark status adds a layer of formal protection on top of the National Register listing, meaning significant exterior changes face review. For a house that has anchored the hill's high ground for more than a century, that oversight is the price and the point of its prominence.
More than a century on, the Martin House remains exactly what its builder intended: the most conspicuous address on the most conspicuous street of one of Minneapolis's grandest neighborhoods.
The Lowry Hill East Neighborhood Association reviews apartment and land-use proposals in the Wedge through its Community Development Committee, the volunteer-led forum where the neighborhood weighs in before projects reach the City Council.

Land use is the recurring flashpoint in Lowry Hill, a neighborhood of Victorian and Prairie-style homes where even a modest multi-unit proposal draws scrutiny under the city's built-form rules and the 2040 comprehensive plan.
