MMLP are housing architects in Illinois, assisting clients to spend their shrinking maintenance dollars to the greatest effect. MMLP are commercial architects in Illinois, providing Interior Design services to create healthful and productive workspaces. MMLP are historic architects in Illinois, using our experience in the products and building techniques of the past to move historic buildings into the future. The Analytical Design Group (ADG) division specializes in environmental issues in buildings: mold, asbestos, lead-containing paint and indoor air quality. MMLP and ADG emphasize close and continuing communications with clients on each unique project whether remodeling, new construction, historic renovation or green and sustainable design. All projects receive personal management by a MMLP principal architect to assure a responsive and well-managed project from start to finish. We will take the time to understand you and your design needs. Instead of imposing an aesthetic on you, we start by listening and incorporate your style and tastes into the design concept to enhance the functionality of the space. MMLP’s architectural services are comprehensive and cost effective.

Ralls Melotte


Principal (Retired 2019)

Mr. Melotte was sent off in style to a well-deserved retirement November 15, 2019.  Hailing originally from Fort Atkinson, WI, he returned to his roots when he purchased a home in Kewaunee, WI.  Ralls has a bright future as he embarks on a new writing career from his Wisconsin residence.

His 50+ years of experience included a full range of services for institutional, historic, residential and governmental clients.  Much of his work was in existing buildings and with non-profits requiring creative solutions both architecturally and financially.  He had started a stained glass studio which helped satisfy his more artistic side when he partnered with Richard R. Morse to create Melotte Morse, Ltd. Architects in 1978.  As a part of dealing with older structures, Ralls became a licensed Asbestos Designer & Lead-Based Paint Inspector/Risk Assessor, and was quickly acknowledged an expert in correcting and preventing moisture damage and mold remediation.   Ralls directed MMLP’s environmental services division, Analytical Design Group (ADG) for the last 25 years.

We at MMLP have all learned an incredible body of knowledge from this tireless individual.  Not least of that knowledge is how to work with people and resolve conflicts.  His care for people, his conviction in doing the right thing even when it was uncomfortable and his dedication to understanding complex regulations is and will continue to be an inspiration to us at MMLP.  He leaves a legacy of professionalism and community involvement that we at MMLP fully intend to build on.
