"Marc did a great job on our garage expansion project! He was friendly and professional, taking all of our ideas and criteria and combining them into a great layout. The drawings themselves look great. We are still shopping the plans around to contractors, and Marc is always helpful with advice or ways to reduce cost. Would definitely recommend him to anyone looking for an architect."

"Architect Kristin Kollias has provided me with professional and responsive help in the renovation of a vacant single family bungalow in Chicago that required extensive repair for compliance with the City of Chicago codes. She assisted in guiding me in obtaining required site plan for the residence; addressed the structural, electrical and plumbing details required; drafted and created the architectural floor plans that fit my vison of interior space; and facilitated in obtaining the necessary city permits from City of Chicago. Clearly she is a true professional and her services are greatly appreciated."

"I am having a full master bath and kitchen remodel done with new layouts in both rooms and knocking out a wall. Evolution worked with me to quickly get a drawing done of the new layouts so that the contractor could get started on the project. They made sure to include me in the process so that the design would be done exactly as my wife and I envisioned. They communicated effectively throughout the process and were always courteous and professional. I recommend them to anyone with drafting needs."

Structural Engineering questions, answered by experts

Their expertise in identifying potential problems early and implementing durable solutions safeguards your home’s integrity.

Costs depend on desk size, labor, included features like drawers or motorized height adjustments, and required wall anchoring.

Costs depend on material choices, labor, and the extent of structural modifications.

Yes, an LVL beam is more affordable than the cost of a steel I-beam, totaling between $50 and $200 per linear foot as opposed to the $100 to $400 per linear foot you’d pay for a steel I-beam. Not only is the wood material more affordable than steel, but it’s also more similar to traditional wooden beams and doesn’t require as much retrofitting to connect joists.

Structural engineers draw structural plans, which include detailed drawings of the structural components of a home only. Complete house plans will require additional work from an architect or draftsperson, whose drawings will take the structural drawings into account. They’ll also include more details about the finishing materials and layout of a home, including everything from roofing and flooring materials to the position of furniture, light fixtures, switches, and plumbing fixtures.
