Customers say: Super punctual

"Martin and Jake are the absolute best to work with. They were thorough, efficient, professional and so easy to work with for our basement structural work. They took time to explain what needed to be done, coordinated with different contractors (plumbing, electrical), and were able to complete our project on time while we were out of town for just a week(!!). I can't recommend Great Lakes Builders more - they were a pleasure to work with and we will absolutely be using them again for any future work we need. 5+ stars!"

"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."

Structural Engineering questions, answered by experts

You should avoid drilling or cutting into load-bearing beams because removing material will weaken it and increase the risk of structural damage or even collapse. If you do need to drill into a load-bearing beam, speak with a structural engineer first to discuss where it’s safest to drill and the width and depth of the bit that’s safe to use.

It's safe to assume that all exterior walls are load-bearing, or at least have load-bearing characteristics. Some older homes feature porches or bump-outs that don't rest on the home's foundation. However, they still must carry the weight of the roof section they support. Walls containing floor-to-ceiling glass or other non-structural elements must use post and beam configurations to meet load-bearing criteria.

A construction manager is particularly useful in the case of a large-scale build with custom design elements, so it’s usually worth it to hire one. They can help manage your budget, maintain quality control, oversee timelines, and navigate unexpected hurdles. While construction managers are pricey, they can actually save money in the long run by identifying cost-saving opportunities and ensuring the project stays within budget.

The standard thickness for an LVL beam is between 1.75 inches and 7 inches. However, you can order LVL beams in non-standard sizes as well. When you work with a contractor, they can source beams that are the appropriate size for your project for you after assessing your blueprints.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.
