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

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
