SoWa Power Station at 550 Harrison Avenue is a South End event venue created from a former power plant. The official site describes more than 30,000 square feet over two stories and lists weddings alongside corporate, nonprofit, and social events. It is a large architectural setting, so room selection and guest flow should lead the initial planning conversation.
Use the published capacities as configuration cues
The venue lists the mezzanine at 125 seated or 250 for a reception, while the main floor is listed at 1,050 seated or 1,500 for a reception. It also notes that events above those stated configurations may need permits and approvals. A wedding inquiry should therefore specify ceremony, dinner, dancing, and cocktail layouts instead of relying on one maximum number.
Know the food and bar model
SoWa says it holds the liquor license and manages bar service in-house. It works with a curated list of Boston-area caterers for food. Ask for the current approved catering roster, bar options, setup requirements, and any planning or production conditions that apply to the proposed configuration. The reviewed public sources do not state a universal wedding price or weather plan.
