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."

From concept to completion, Capizzi Home Improvement has the experience to handle any custom home renovation whether it is interior or exterior. We are a trusted full-service home improvement and remodeling company serving Cape Cod and the South Shore.

"After many years of Indecision we recently concluded it was time to put in a new kitchen. From cabinets, floors, walls, ceilings, appliances and finally painting - the works!!! We chose Capizzi Home Improvement Company. We had heard they were excellent and had a great reputation for customer satisfaction. We had no idea of the scope of the job and all the work they would have to accomplish. Needless to say this was a very smart choice on our part. From the start there was our designer Diana then to the Caroenters, Jimmy and Dave, the Electricians Dave and Andrew, the Painters Joshua, Jesus and Freddie and the Plumbers Bill and Charlie - all contracted through Capizzi. All were fantastic at their trades. Very professional and knew what they were doing. All of the above coordinated through Gary who managed it all! I would recommend this crew from top to bottom. What a great job they all did! Super, super, super. Kudos to all! P.S. Highly Recommended!!!"

"Pierre construction is Awesome!!! If you’re looking to have someone to do your next project, look no further. I spent quite a bit of time interviewing and getting quotes for a major 2 story deck project for my house which included some intense structural improvements to my house as well, since some of the existing columns where in tough shape. I’m so glad that I picked Dave Pierre and his great crew to do this for me! Dave’s price was very reasonable and he was very much on top of all details. He bent over backwards to make sure that I was happy with every step of the project. His crew of over 12 years was also very skilled and often had discussions about challenges to make sure the details where the best that they could be before proceeding on the the next phases. As you can see from the attached video of the 2nd floor, the results are fantastic and I’m enjoying my new space immensely. "

FAQs for addition to existing structure building service projects in Plymouth, 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.
