MB Design is a boutique architectural design and construction company offering personalized design and construction services tailored to maximize your budget. We specialize in Architectural/Interior design and Full Home renovations.

"If you are deciding between contractors, stop thinking about it and hire Martins, I promise you will be happy with your decision. It is hard for me to put into words what an unbelievable job Martins did with our built ins and how much I enjoyed working with him. My wife and I were nervous because we had never done any sort work on our home and finding Martins was a godsend. In all honesty we are very picky and sometimes hard to work with (just ask our wedding vendors haha) but I cannot think of one thing we would have change in our experience working with Martins and how the built ins turned out. He is very good at what he does and just a very honest guy that you can trust with your project. He cared about how everything would look and function almost more than we did if you can believe that. His attention to detail was impeccable and is exactly what you want when you are making a big change to your living space. Every one of our friends that come over are in awe of our new built ins. Martins is a true artist!"

Structural Engineering questions, answered by experts

Yes, you can put a doorway in a structural wall; in fact, most exterior doors are set into structural walls. The project is a little more challenging than installing a door in a non-load-bearing wall because you need a structural engineer to assess the wall and make sure it’s safe to create a wall opening. Your engineer’s report will include instructions for your contractor on how and where to install additional supports, like steel headers above the door, to distribute the weight above to the wall on either side of the door.

Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.

You should pick steel for your new support beam for a few reasons. While steel is more expensive than other materials, such as laminated veneer lumber or glulam, it offers the following benefits:

  • Fire-resistant

  • Unaffected by pests

  • Longer-lasting

  • Stronger against water damage (when galvanized against rust)

A structural engineer’s report is almost always worth it, as it can help you avoid buying or overpaying for a home with structural issues. The most important thing the report does for you is provide peace of mind that you won’t have to pay thousands of dollars for structural repairs right after closing on a property.

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.
