A completely rebuilt one-level home with commercial potential, 900 S Irwin Avenue Ext offers a unique opportunity to live and work from the same property. The approximately 0.70-acre property may also offer the potential to be subdivided into two separate parcels in the future, with one parcel potentially pursued for commercial use. The kitchen is the centerpiece of the home, featuring custom cabinetry, stone countertops, an oversized island, stainless steel appliances, a gas range with a statement hood, extensive workspace, and a walk-in pantry. The kitchen opens into the dining and living areas, creating a bright and inviting space for everyday living and entertaining. The living room offers abundant natural light, recessed lighting, and a fireplace. The primary suite features a vaulted ceiling, large windows, private exterior access, a walk-in closet, and a spa-inspired bathroom with a freestanding soaking tub, separate glass-enclosed shower, custom cabinetry, and designer tile. The additional bedrooms are spacious and filled with natural light. A beautifully finished secondary bathroom includes a tiled tub and shower combination. Outside, the full front porch, mature trees, and level yard create a peaceful and private setting. One of the most distinctive features of this property is the detached flex building located only steps from the main residence. It provides excellent space for a home office, private studio, workshop, online business, creative space, or additional storage while allowing the work area to remain separate from the living space. An additional storage building provides even more usable space. The property is located next to an established commercial area, creating a unique opportunity to live and work in one convenient location. The surrounding commercial activity, easy access, and detached flex building make it easy to keep a business close to home while maintaining separation between work and everyday living. Municipal water and sewer, central heating and cooling, and convenient access to downtown Spartanburg, shopping, restaurants, and major roads complete the property. This is a rare opportunity to own a fully redesigned home with the space and flexibility to live and work from the same property. Any proposed business use, expansion, or conversion of the detached building is subject to applicable zoning, permitting, and licensing requirements. Buyers should independently verify their intended use with the City of Spartanburg.
