    MC zoning introduces versatility and long-term value in this beautifully updated, move-in-ready character home set in the heart of Marda Loop. Investors appreciate the redevelopment potential on an increasingly sought-after corridor, business owners gain a rare chance to live and operate in a walkable commercial hub and families enjoy the charm, comfort and function of a single-family home with a remarkable outdoor living space. Character from the original 1914 build adds warmth through wide profile windows, preserved wood elements, exposed brick and thoughtful architectural details that pair seamlessly with extensive modern upgrades. A welcoming entry sets the tone with shiplap and wide luxury vinyl plank flooring that flows into a relaxing living room framed by an exposed wood beam and elegant wainscotting. The dining area sits beneath striking designer lighting and blends easily into a renovated kitchen finished with quartz counters, full-height tile, stainless steel appliances, fridge with a French door, a gas stove and updated white shaker cabinetry for everyday ease. An adjacent family room enhances daily comfort with an electric fireplace and tranquil views of the backyard from oversized windows, creating a natural spot for unwinding. This level includes a Main Floor bedroom and a 4-piece bathroom for flexible main-floor living. Two additional bedrooms rest on the upper level along with a stylish, recently renovated 3-piece bathroom with modern black hardware. The basement provides valuable bonus space for a gym, play area and storage with easy access to mechanical systems and exterior storage beneath the rear addition. Recent improvements introduce durability and peace of mind, including a high efficiency furnace (2022), hail resistant asphalt shingles (2022), acrylic stucco (2022), vinyl plank flooring, new paint, updated PEX piping and a fully refreshed kitchen completed in 2023. Outdoor living is unmatched with an extra deep fenced yard designed for hosting, complete with ornamental grasses, a deck for barbecuing and an incredible covered entertainment pavilion with lighting and lounge space that extends the seasons. Privacy and security come through with the newly built fence fully encompassing the yard and thoughtful landscaping that frames the yard beautifully. This location places you within minutes of the shops, cafes and amenities of Marda Loop, close to schools, parks, transit and quick routes into downtown, Altadore, South Calgary and the river pathway system. A rare combination of historic character, modern comfort and multi-use flexibility (great holding property) creates meaningful opportunities for a wide range of buyers!

    Why Choose Inner City Homes in Calgary?

    #1 - Convenient Location

    Location plays a huge role in the high demand and desirability of inner city real estate in Calgary. Close proximity to amenities, services, parks, playgrounds, schools, recreation, and of course, the downtown business core, are just a few benefits of the inner city lifestyle.

    Properties in Calgary's inner city are found in prestigious enclaves on quiet streets with mature vegetation. Paved pathways along the nearby river serve to interconnect residents with amenities and other parts of the city centre with ease.

    Check out Calgaryism's list of the best inner city parks our city has to offer. Chances are a few of them will be near your future property!

    #2 - Modern Living

    Calgary inner city homes often are customized with high-end features that cater to the needs of buyers and their families. New infills are especially desirable, with luxurious characteristics that sometime exceed all expectations. These properties showcase the work of some of the best custom builders in the city, offering sophisticated living in a high-density urban setting.

    What is an infill home anyway, you might ask? Basically there are two different types you can buy in today's residential market:

    #3 - Family-Oriented Communities

    Calgary's inner city neighbourhoods are family-oriented because of their higher density settings. These "tight-knit" communities afford families and friends the opportunity to grow with one another and create lasting memories at nearby parks and amenities.

    Neighbours are usually friendly and will look out for each other's common security and well-being. Schools are also found in abundance near any inner city home in Calgary; most areas have their very own in-community public elementary school with junior and senior highs often within walking distance for mature students. Dropping the kids off at school when they are younger sometimes means just walking down the street a few blocks.

    Parents often save so much time from the conveniences of inner city living that they have another hour or two to spend on more important things in life. Work, study, cooking, or perhaps taking care of your family; less time spent in traffic means more time enjoying the inner city real estate you've worked so hard for to buy and maintain!
