The Narrow Lane Company is a full service landscape company dedicated to creating and maintaining beautiful outdoor spaces you'll absolutely love! All work is done in a timely, professional manner and 100% guaranteed.

"Worst experience working with a contractor we have ever had. Lack of communication was astounding. Reached out to start the project on our tiny front lawn in June/July. Didn't start planting until mid October. Was told there were 5 jobs in front of ours. Ignored photos of exactly what we wanted. Finish product is passable at best. Would not recommend."

Marco Polo Home Builder has been building homes & doing renovations all over Massachusetts with a great combination of skills-building knowledge, craftsmanship, and professional project management. Over the years, we understood that construction is about wood, bricks, and family. We take our job thoughtfully because we know that a home is the most sanctified place for a person. We value our clients' needs and work with our crew and subcontractors to prioritize them. We aim to make your dream project a reality and hope to be on this journey with you.

"In addition to the kitchen, they also remodeled our bathroom. Marco was sensitive to the fact that we only had one bathroom and made sure we were out the facilities for the minimum time possible. Our bathroom remodel was completed with lightning speed which we really appreciated! The kitchen remodel was also speedy. They worked with our requirements for smaller than usual appliances, finding, and even building, cabinets to fit our small kitchen space. Everyone who worked on our projects were very professional, wearing masks and keeping windows open even in the winter months. We're very happy with our new kitchen and bathroom!"

Addition to existing structure building services FAQs

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.
