"Fine Design did a great job on our bathroom from the gutting to the finish. Dave and Lenny were easy to work with and the workers were great! Cleaned everything up each day and were very polite. The quality of the work is outstanding. Everyone was very professional and was a much more pleasant experience compared to other contractors I have used. Thanks again-I highly recommend Fine Design."

"Anthony and his crew were friendly and professional throughout the whole project. Anthony gave us a clearly broken down estimate prior to starting the work and we were very confident in his work from start to finish. He and his crew did an excellent job and we would absolutely use him again for future projects. His prices were reasonable and comparable to other quotes we received-he provided us with a clear payment schedule over the course of the project, communicated with us every step of the way and went above and beyond to give us tips and additional info that was helpful to us as new-ish homeowners. Would absolutely recommend."

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"Norman helped us to make our Master Bathroom modern and usable. The process was easy, straightforward and relatively quick! Norman's showroom was a great meeting spot to review and talk about design, choose materials and go over any details. He was communicative and helpful in answering any and all questions throughout the process. We are thrilled with our new Master Bath that feels like we are at a hotel or spa. Thank you Norman and team. Highly recommend Homecraft!"

"We live in a prewar coop building in Manhattan and were in need of a kitchen, living and dining room/den renovation. Because of the limitations in our building, we were not optimistic that many changes could be made that would dramatically alter the feel/function of the space. Inson Wood proved us completely wrong. With his architectural eye and his impeccable design aesthetic we (and everyone who has been here before and after) experiences our apartment as an entirely different living space. Even family members are shocked at the transformation. I think that what Inson accomplished was the product of a few significant factors. First, Inson asks you what you want and seriously considers how you live. If Inson thinks that different approaches should be considered for what you want, he provides renderings of each option so that you can easily visualize and imagine them. Ultimately, Inson respects your preferences and works with them, elevating them to a level far above what you had imagined. Inson uses the highest quality vendors (whom we NEVER would have found) and expertly guides you through choices (note: follow his recommendations!!!)- our walls would never have had dimension and our kitchen backsplash never have been so unique (two examples) if not for the artisans that Inson uses. Inson is also willing to have you be as much or as little involved in the process as you want to be. I did go with Inson to choose many pieces of furniture but realized after a certain point that his taste point made me confident in him choosing much finishing work (ex: window treatments, decorative cushions, which I love) without me. As with all design work, there are always glitches and Inson was extremely responsive and responsible for taking care of those as they came up. We are nothing less than thrilled to come home each evening and enjoy our space, which feels like a luxurious retreat perfectly tailored to us."

"Working with Sun Lux & Ace was a remarkable experience. We had originally met Ace at an Open House for one of his other Builds. From there, we realized we had to work with him from seeing his quality of work and expertise. Ace handled everything from assisting us in designing the home with his Architect, to submitting the plans and all amendments, to expediting the permits, to delivering an end product that we are extremely happy with. He was kind enough to guide us in upgrades that weren’t originally part of our original scope of work that made sense and told us to stay away from certain products/design choices that were a waste. On top of that, he was extremely respectful and understanding throughout the entire process. We always felt we were in safe hands with Ace and his team. Looking forward to building another one with him within the next year."

FAQs for addition to existing structure building service projects in Jericho, NY

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
