"We added a great room, entryway, deck and second floor room to a ranch. Kip has a great design sensibility and we worked together without an architect to come up with a plan. We've been extraordinarily happy with the result; we love the house. The older section works seamlessly with the newer section. Kip pays attention to details. After the work was done, Modern Habitat has been responsive to whatever issues that arose. We are truly appreciative!"

"Dave and Kim came highly recommended by our architect and built a life changing in-law addition to our home and also took on some much needed renovations in our existing home. I'm writing this a year after the work was completed and could not be happier. The quality of the work was great and Dave and Kim kept every promise that was made. I also feel that the trustworthiness of any vendor or contractor can especially be measured when something goes wrong. While it was rare, we had a couple understandable miscommunications along the way. They were extremely fair with how these were handled. Construction costs are so high that it feels really good to still feel like it was money well spent. We also looked at other reputable contractors in the area and found their prices to be competitive. The contractors they worked !with also showed up when they said they would and were polite. Overall it was a really positive experience."

FAQs for addition to existing structure building service projects in Allston, MA

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.
