"Competent and reliable team, solid schedule, very professional result. Neighbors see their results and often seek their help. Straightforward and knowledgeable. Comfortable interaction since 2015. They stand behind their work and take pride in it. We have a house built in 1838 which needed external repairs to deal with weather, recently becoming more severe. They reconstructed and restored an upper rear deck, dining room porch and far-back lower deck, repaired a front dormer, repaired an entire front & side façade and then recovered it with new clapboard, installed millwork around new Pella windows, installed real shutters, & a far-back canopy. They rebuilt an elaborate rear yard fence and built a privacy gate. It is our pleasure to write this review, we feel lucky to have them available."

Lightship Development LLC is committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty, and personal responsibility. Our distinction is the quality of service we bring to our customers. 28 years of accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests, and make their concerns the basis of our business.

"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."

We are a licensed and insured residential construction and remodeling company. Our goal is to exceed all of our clients expectations through exceptional customer service and quality craftsmanship. We work with some of the best tradesmen in the industry to deliver a quality finished product. From kitchen and bath remodels to carpentry and painting, we can do it all. Contact us for an estimate on your project today! Check out our instagram for photos and updates @coenconstruction

"I thought I'd provide a 6-month update on the work performed by Coen. In short, we selected them to do some minor renovations to the bedroom and living room - ceiling repair and electrical work - and then paint the entire interior of the unit. It was horrible. We settled a reduced fee and went our separate ways. Since then, we've had to remove the work they did and repaint the entire hallway, bathroom, and kitchen due to paint peeling. Based on the prior experience and having visited during the renovation, they didn't prep a single thing - the walls definitely needed that even prior to other work starting. The new contractors very clearly were able to show how the surfaces weren't prepared at all for paint related to dust under all of the layers from the drywall and other construction work they did. Not a single apology or visit from the owners to date. Don't waste your time, money, or effort on this company whatsoever."

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

Yes, you can add a bathroom on a concrete slab, but the crew will need to saw-cut the slab, trench in new supply and drain lines, and then patch the concrete without weakening the foundation. Working with an experienced plumber and concrete pro keeps the structure intact and helps the new bathroom pass inspections.

schedule covers planning, permits, framing, rough-ins, finishes, and punch-list items. 

Larger spaces or extensive plumbing and electrical upgrades can stretch the timeline, while a simple powder-room conversion may wrap up faster. Hiring licensed pros helps keep the schedule on track and the work up to code.

The best location depends on how your family uses the space. An upstairs bath keeps nighttime trips close to the bedrooms, while a first-floor powder room is handy for guests and everyday traffic. 

Think about where plumbing lines already run, how much square footage you can spare, and what layout changes fit your budget. A pro can map out the smartest spot and handle any code hurdles.

With the right planning, you can carve out a bathroom in almost any part of the house. A successful addition requires sufficient space, proper ventilation, and access to plumbing and electrical systems. Structural modifications and adherence to building codes are essential. 

This process demands careful planning and the coordination of specialized professionals who ensure that the new space meets all code requirements and functional needs.

Under specific conditions, adding an extra bedroom can boost home value more than adding a bathroom. Home value is driven by overall configuration, market demand, and functional balance. A new bedroom influences the property’s appeal in different ways, while an additional bathroom enhances living convenience. Evaluating the current layout and market trends determines the optimal choice for maximum value.
