Before & After transformation in St. Louis’ Shaw neighborhood.

This four-unit building renovation brings new life to a classic St. Louis building type, retaining its historic details while making the interiors feel more open. Kitchens and bathrooms were updated with modern fixtures and layouts, creating functional living spaces within the original footprint.

The project utilized historic tax credits, which guided the drawing process and informed exterior material selections, including replacement windows designed to match historic profiles and standards.

Projects like this are a reminder that preservation is also about adapting existing buildings for contemporary living and providing homes for a new generation of residents in the Shaw neighborhood.

Killeen Studio Architects worked with Killeen Counseling to adapt this existing Webster Groves residence into a welcoming counseling practice. The renovation includes interior updates throughout the building, including the conversion of an existing second-floor bedroom into two private offices.

The design preserves the floor plan of original building while creating comfortable, functional spaces suited to its new use. Original wood floors, traditional trim, existing windows, and the scale of spaces work to create an environment that feels rich and intimate. A restrained material palette: warm wood, muted earth tones, painted millwork, and simple furnishings, carries that character into the renovated spaces.

From refreshed interiors to carefully integrated office spaces, the project demonstrates how existing buildings can be successfully reimagined for contemporary needs. Own an existing building ready for its next chapter?

Completed near Cliff Cave County Park, this multi-level garage and artist studio makes use of the site’s natural grade, with vehicle storage at the main level and a light-filled artist studio above.

A gabled roof, exposed structure, stone accents, and painted siding give the building a character that feels at home within its wooded setting.

KSA is proud to be part of the team reimagining the Westborough Country Club campus—rethinking access and circulation while helping coordinate improvements to tennis, pickleball and bocce courts, landscaping, and other major site elements.

The result is a more cohesive and connected campus that strengthens the relationship between the clubhouse, recreation, and surrounding grounds.

After a devastating fire in 2011, this Maplewood Craftsman was carefully reconstructed with a focus on retaining the character and details of the original home.

Historic photographs, sketches, and floor plans helped guide the reconstruction, from the cedar shake siding and trim details to the proportions and Craftsman character throughout.

41 Penn — completed in 2007.

This five-story mixed-use condo building sits in the heart of Westport in Kansas City. A little piece of project history: the St. Louis Cardinals won the 2006 World Series while the building was under construction.

Nearly 20 years later, 41 Penn remains part of the fabric of one of Kansas City’s most vibrant neighborhoods.

A quiet retreat in the woods.

This screened porch addition in Des Peres extends the home into its wooded surroundings, with warm timber framing, and expansive screened openings framing the landscape beyond. The natural color palette and filtered light give the space a warm, calming quality.

Completed in Benton Park, this 4,300-square-foot custom home was designed for a local couple who purchased a vacant lot to build their dream home.

Drawing inspiration from the neighborhood’s iconic 1880s factory buildings, the home blends industrial chic with contemporary living. Tall ceilings, exposed beams, expansive windows, and an open floor plan create bright, flexible spaces.

The home features three bedrooms, two full bathrooms, one half-bath, a full basement, and an Energy Star-qualified, super-insulated envelope paired with high-efficiency mechanical systems and appliances. Aluminum windows, hardwood flooring, and a brick veneer exterior complete the design, balancing durability, energy performance, and warm character.

We’re grateful to our clients for the opportunity to help bring their vision to life and create a home that reflects both their story and Benton Park’s architectural legacy.

Killeen Studio Architects is proud to announce the design of a new 165-unit multifamily community at the corner of Missouri and Chouteau Avenues. Rising five stories above a parking and amenity podium, the development introduces contemporary urban living to St. Louis' iconic, architecturally rich Lafayette Square neighborhood.

The building will transform what is currently a parking lot and is part of a broader neighborhood initiative to restore and strengthen this northwestern edge of Lafayette Square, creating a more connected transition between the neighborhood and Downtown St. Louis.

Working closely with the City of St. Louis' Cultural Resources Office and Preservation Board, the design reflects elements and materials of Lafayette Square's built environment while establishing a distinct identity at this prominent corner.

Upon completion, residents will enjoy extensive amenities, including:

• 5,000-square-foot fitness center
• Golf simulator
• Resident market, public café and bistro
• Coworking spaces and meeting rooms
• Top-floor club room
• Dog spa
• 2,000-square-foot resort-style pool
• Nearly 19,000-square-foot pool deck designed for gathering, recreation, and relaxation

As the companion building to the successful 2200 LaSalle—currently 98% leased—the project draws inspiration from neighboring 2300 LaSalle while establishing its own architectural presence within the district.

We're grateful to our client, Graddy Investments of St. Louis, the Lafayette Square neighborhood, and the many collaborators whose partnership helped shape this vision.

A special thank you to Carlos Goldberg for his leadership throughout the design process. We look forward to sharing construction progress as this exciting addition to Lafayette Square takes shape.
