"An Outstanding Renovation Experience with White Maple Construction From outdated to ultramodern, White Maple Construction led by the brilliant Ryan Brining has executed an awe-inspiring transformation of my kitchen. They catapulted my cooking space from a â That 70s Showâ backdrop into a sleek and sexy entertaining space reminiscent of the opulence seen in â Successionâ . The transformation started with the meticulous removal of the decades-old vinyl flooring, layers upon layers of it, an endeavor that revealed the teamâ s dedication to detail and quality. What followed was a thoughtful renovation plan that involved knocking down unnecessary walls, instantly opening up the space, and infusing it with modern chic design elements that I could only dream of before. A particular highlight of working with White Maple Construction was the teamâ s exceptional responsiveness. Ryan and his team promptly answered every call, making us feel heard and valued at every step of the project. They even went above and beyond, coming over late in the evening to address a concern about our heating system after a dayâ s work, demonstrating their genuine care for our comfort and satisfaction. Beyond their aesthetic expertise, what set White Maple Construction apart was their seamless collaboration with skilled plumbers and electricians. Their collective attention to detail and mastery of their respective crafts was evident in the precision and quality of their work, instilling confidence in us throughout the process. Despite their luxurious execution, White Maple Construction operated with budget-conscious efficiency. They made it possible for us to achieve our dream kitchen without breaking the bank. They turned a dated, enclosed space into an open, modern, and functional masterpiece, making us feel rich in style without feeling poor in pocket. Iâ ve included some before and after photos to give a hint of the transformational magic conjured by Briningâ s team. However, no picture can fully encapsulate the astounding depth of change made possible by these skilled professionals. To sum it up, if youâ re looking for a construction team that delivers on promises, exceeds expectations, and takes your design dreams to the next level, White Maple Construction should be your go-to choice. Their fusion of outstanding workmanship, efficient collaboration, budget-conscious planning, and exceptional customer service results in a renovation experience that is nothing short of remarkable."

Our mission starts with how we propose your custom new home building construction project. We want and prefer you see the phase-by-phase costs we incur from permit to clean up. When you receive our proposal, you will notice that we proposed a cost plus a fee pricing, usually referred to as just “cost plus,” or “open book”. This is defined by adding two components together: Costs the builder incurs to deliver the scope of work + Builder’s fee for delivering the scope of work at builder’s cost. Open book provides the transparency missing from a lump sum price. It allows you as the client, to share in the benefits that come from 0% markup on material and subcontractors. Every two weeks you receive and budget vs actual spreadsheet allowing you to apply savings to other scopes that may have been cost prohibitive. We as builders pass project savings to you, our fee is transparent. See the video for more...https://www.youtube.com/watch?v=XnuIc3GrBWA

FAQs for addition to existing structure building service projects in Ho Ho Kus, NJ

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.
