Walsh Custom Homes is a family owned business that has operated in Chicago, and the surrounding suburbs for over the past 20 years. We specialize in second floor and rear additions. Please contact us today for a consultation on your next home improvement project, at your beautiful home. Thank you!!

"Jim is a nice enough person to work with if you do not have a timeline. Some of his subcontractors are great like flooring. Others, particularly his plumber, are terrible. Multiple code violations and callbacks to fix issues. My advice if you decide to use Jim is to not use allowances and make him provide a fixed price contract. He likes to make up the difference in his cheap quote to get your business by having most allowances categories come in much higher."

"Bob and his crew are the best. This was a major renovation and complete re-do of a split level house that we converted to a more traditional house. 95% of our house was redone. Bob is meticulous and his subcontractors are fantastic at their crafts and very loyal to Bob for good reason. He was pretty instantaneous in his communication with me even on weekends, which we rarely bothered him in. This was a mid 6 figure job that Bob said would take 4 1/2 to 6 months. They finished in 5 1/2 months which is pretty amazing during a pandemic with major supply chain issues. Bobs bid wasnâ t the lowest, but it wasnâ t the highest of the 5 bids we received. They were pretty much on budget except for material price increases, especially lumber which was not his or the lumber yards fault. If youâ re thinking of hiring MZ Development you will not go wrong if you hire them to do whatever size project you are thinking about."

"The team at Quintessential Renovations Inc. did a fantastic job replacing the cabinets in my kitchen! I could not be happier! Highly recommend them! They had the best customer service, all of their workers were friendly, clean, on time, and highly respectful. They did all of the correct prep work on the job and they really respected my home and belongings. They used great drop cloths and covered everything! They did almost all of the work in just two days and the entire project was completed in less than a week. Their estimate was right on the money and they worked so hard to keep things right where I needed them to be financially. They came up with creative solutions to my storage needs, designed some cool new corner cabinets, and gave me the greatest deal on the top of the line countertops that I just rave about!

His team worked tirelessly over the Thanksgiving week and into December to complete the project on time and delivered an exceptional work product. Ruffino and John were amazing and did excellent work, being flexible to changing needs and providing a beautiful end result. They went above and beyond and helped move furniture around the house and even a couch to another location. The best part is they were very affordable and came in on budget and exceeded expectation.

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
