ST. LOUIS — Four homebuilders plan to construct 35 single-family homes and 12 condos on vacant lots scattered throughout the Gate District neighborhood just east of St. Louis University’s medical campus.

The plans came in response to an August request for proposals issued by the SLU-affiliated St. Louis Midtown Redevelopment Corp. and the Gate District West Neighborhood Association. SLU has owned the vacant lots in the neighborhood for years.

“The partnership with these residents to create something that honors this community is a blessing,” SLU President Fred P. Pestello said in a statement. “I want to thank our St. Louis community neighbors for sharing our vision for and commitment to growing stronger together.”

Construction could start this spring. The houses will be two stories with three to four bedrooms and priced in the $300,000 range. The two-bedroom, two-bathroom condos will be priced in the $200,000 range. Homes in the neighborhood had an average sales price of $205,000 last year, according to city data, up from $180,000 in 2014.
