"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."

"I hired Platinum Touch Industries LLC in the summer of 2018 for my first Fix and Flip remodel project and was impressed with their work. Vince and his team did a fantastic job from demo to cleanup to the finish touches per schedule. Vince was honest at front and very professional. Based on the Scope of Work I presented to him, we were all in the same page. Once milestones were completed within the Project Timeline, payment was made to him in a timely manner. Platinum is honest, reliable, and work ethic is impeccable. I was impressed with their work and demeanor, I hired them again the winter of 2018 for a minor remodel on one of my rental properties and in the Spring/Summer of 2019 for a Major Rehab on a Fix and Flip project in the Lombard area. I would recommend Platinum Touch Industries in all aspects for your Construction Project, whether it is a minor remodel to a major rehab. Thanks Vince and Bob for all you do. Keep up the Great Work!!!"

"We now have a beautiful kitchen. This price tag was on the high end, but that may have been due to either the high price of lumber at the time (Canadian wildfires) or the customer cabinetry that we needed or both. There were a few instances where I was glad we were on sight as I don’t know if the errors we saw would have been caught prior to them being installed. The upfront design and visualization is top notch, as is the quality of the material. The labor used to install was three star at best."

Addition to existing structure building services FAQs

Converting an existing space into a laundry room is more affordable than building a new addition. While new additions start at $5,000, renovating an existing space for laundry use can begin at $1,300. 

Your specific costs will depend on whether plumbing and electrical connections exist nearby, the quality of finishes you select, and whether any structural modifications are needed. Always budget extra for unexpected issues, particularly in older homes where hidden problems might surface during renovation.

The smallest practical size for a new laundry room addition is 35 square feet, which provides enough space for basic appliances and minimal storage. For renovations utilizing existing space, smaller footprints might work with space-saving solutions like stacked appliances. 

A standard-sized laundry room of 60 square feet offers more comfort and functionality, allowing for counter space and storage cabinets. The optimal size depends on your household needs and available space.

Yes, adding a laundry room requires several permits, particularly for new additions. You'll need building permits, plus specific permits for electrical work, plumbing installations, and possibly HVAC modifications. 

Requirements vary significantly by municipality, so consulting with your local building department before starting work is essential. Proceeding without proper permits can result in fines, mandatory removal of completed work, and complications when selling your property.

The timeline for completing a laundry room addition varies based on project complexity, contractor availability, and permit processing times. Factors that can extend the schedule include material delivery delays, weather conditions, and unforeseen structural issues discovered during construction. 

Renovating an existing space often requires less time than building a completely new addition. Working with an experienced contractor who can coordinate various tradespeople efficiently helps keep your project on schedule.
