Our Basement & Attic Conversion Services

Properly refinish your basement or attic with NEDC's expertise

Leverage the available square footage of your home without needing to increase its footprint

Refinishing your basement or attic is a fantastic way to leverage the already available footprint that your home offers. Many times homeowners find themselves in a situation where zoning codes won't allow the building of an addition. This is when using your basement or attic becomes a viable solution.

Attics are generally preferred due to natural light and general air quality, however with modern building materials and techniques basements can now also be brought up to desirable places to be. Attic conversions typically become the following spaces for our clients:

  • Primary bedroom with an en-suite bathroom
  • Extra bedrooms for a growing family
  • Quiet and pleasant work-from-home office space
  • Guest bedrooms and convertible flex-space
  • Accessible storage as well as recreational rooms
  • Partially open vaulted ceilings with mezzanine style rooms

Our Reviews

NEDC is a great choice for a busy working professional. They accommodated my schedule for design appointments and took the time to understand my goals. I felt very comfortable with the lead carpenter and subcontractors and appreciated their focus on minimizing disruption to my condo unit and building. Additionally, their focus on client satisfaction/feedback and continuous improvement is refreshing. Although renovating is not always fun, NEDC helps to make it worth the time, effort, and cost.

David and his team are professional and knowledgeable. David and his team did a great job renovating our kitchen. David communicated with us throughout the entire process – design, project planning, and renovation. He checked in frequently to make sure everything was meeting our expectations. NEDC came up with a design for our kitchen that matched our style and needs while staying within budget and completed on time. We are very satisfied with New England Design and Construction and highly recommend them to other homeowners.

Dustin Wade

Client

Overall, it was a great experience and we still get compliments about our beautiful new kitchen. We hired New England Design & Construction to completely redo our kitchen, and some of the cabinetry in our bathroom. Kara Wilson was our designer and she was excellent, steering us in the right direction again and again. Ryan did most of the construction and he was likewise excellent, a complete professional who did beautiful work, and strived to keep our space as clean as possible.

This is our second project with NEDC. I am impressed by the level of skill and experience of their carpenters. Their communication was very good. One of their greatest strengths is a can-do attitude when it comes to dealing with unexpected situations. The design was perfect and makes great usage of the limited square footage there was to work with. They are much more reliable and courteous than other companies I have worked with.

Ralph S.

Client

New England Design & Construction sets the standard for quality when it comes to remodeling. Their commitment to professionalism, creativity, and training and education is unparalleled. We are so fortunate to have NEDC involved in our association as industry leaders in our region.

Their designs are beautiful and they execute it well. This company is excellent, they stand by their work and guarantee it. Their designs are beautiful and they execute it well. We have had 2 bathrooms and a kitchen done by NEDC, both of them complete gut remodels.

We are so very happy with our new addition. We knew we wanted to hire a design-build company. It was important to us that the team work together to solve issues. It was also important to us to get this project done with the least amount of disruption to our family, specifically our children. Every time I step into the kitchen, I am thankful for New England Design and Construction for making my dream become reality. I highly recommend New England Design and Construction, and look forward to hiring them for my next dream project.

NEDC is simply the best at what they do. Without question this is a 5-star organization. Quality people, quality workmanship and outstanding customer service. Trust your home and the improvements you want to make to NEDC.

Bill Polcsa

Client

NEDC is by far the most professional, organized, honest, contractor I have worked with, and I have worked with quite a few. They were recommended to me by a friend, and I have since recommended them to another friend.

Chris Mill

Client

A great design-build company in an industry where it’s very hard to find honest and quality work. I've had the opportunity to work with Dave and his company on several projects. The quality of their work is superb. As a painting contractor, I'm wary of contractors who often cut corners, leave a messy job-site, and use subpar products. Every single project of NEDC has been very easy to work on. The workmanship and the quality of building products was great which made our job easier.

Bogomil Sabtchev

Painting Contractor

An extremely professional soup to nuts experience. The results look amazing and certainly increased the value and appeal of our home.

Slava Heretz

I give them an A+ in all areas! New England Design and Construction is a team of personable, expert professionals! It's been a pleasure to associate with their business. They have high ethical standards and really can get a job done on time and within budget. You've got a great team Dave!

Joseph Olmos

Subcontractor

Dave and his NEDC team executed our project in a highly professional manner. Extremely attentive to customer satisfaction, meeting timelines and presenting multiple options within established budgets. We absolutely love the finished product and would highly recommend NEDC to others especially if you're interested in having your project well managed from the design concept to completion!

Rico Williams

Client

I recommend them without hesitation. I've had the honor of photographing several projects for NEDC and was blown away by the creativity of their designs and the stellar execution and craftsmanship of their work.

We could not have asked for more. NEDC has a very friendly staff; they were patient and courteous. We have worked with other contractors which were nightmare experiences. NEDC guys were like clockwork. They were very considerate about the home and made it as painless an experience as possible. We have a dog which they even took care of when we left for a two-day vacation.

D. Foster

Client

They are a pleasure to work with and I would refer them to any of my clients. I have worked with the team at New England Design & Construction for several years now on many projects and am constantly impressed with the level of care they have for their clients. The three things that are evident: they truly care about are ensuring they get the project done within the budget agreed upon with their clients; their dedication to getting their projects done on or before the promised time; and of course they pride themselves on their high quality and aesthetic products which result in extremely pleased clients.

We enjoyed working with David and his Team. Very good communication. We are working with them again on another project.

Benson Chu

Client

The company was fantastic to work with. David Supple's designs are beautiful. He clearly has a "we can do anything" attitude and makes it work. During the whole process, New England Design & Construction showed extraordinary professionalism and responsiveness. Timelines were met when possible, and the choice of materials and workmanship was outstanding. The company showed the attention to detail we desired for our high-end property. Importantly, after completion of the work the company quickly and thoroughly responded to any warranty issues or other questions we had.

My home looks better than I would have ever imagined. Everything piece from the design stage through final carpentry details was professionally handled and with open communication. The construction staff are thoughtful, friendly, and a pleasure to have in one's home. The finish carpentry is excellent. My home looks better than I would have ever imagined. I recommend NEDC without hesitation.

Beverly Gillette

Client

Their workmanship is excellent and the process was enjoyable. We worked with NEDC on a complex addition/remodel project and couldn't be happier with the results. We lived in our home during the renovation and they were able to work around us (not always easy) - and were patient and reasonable about the changes we requested. Staff at every level of NEDC worked hard to make sure our finished product reflected our taste and looked like it was always meant to be part of the house. We couldn't be more pleased.

Joel Kor

Client

The people and staff of NEDC are the best. Because of these quality people the execution of the project and the needed communications are exemplary. This leaves no doubt there will be nothing but total satisfaction upon completion of any project.

If you’re looking for a top notch contractor then New England Design & Construction should be your pick. We do multiple mirror and shower installations for them so their showers have to be constructed properly. Every time we install a shower they come out perfect due to the craftsmanship and quality they put into every job they do. This makes my shower doors look beautiful and I'm glad we have paired up together. Both our companies shine bright together, thank you Dave Supple.

Richard Liardo

R&D Glass Company

Hands down my most desirable contractor to work for. I have been working with David for 5 years know and in my 20 years in this business have never dealt with a more professional group of people. They are extremely organized, detail oriented and top notch in every possible way.

Paul Trischitta

Subcontractor

Workmanship was excellent and extras were minimal. The work was done very much as we first agreed. We would recommend them to others.

Minako Henderson

Client

I have only been working with NEDC for less than a year but their entire staff is amazing. I love how they cater to their clients, giving them a custom experience built on great design! Because I work in Interior Design as well, mostly in soft goods, I refer them to all my clients who want to build and/or renovate with absolute confidence.

Kelli Webber

Interior Designer

From initial ideas through the completed project, we felt we were dealing with a professional and responsive company throughout. It was a great feature to include both design and build under one umbrella so that any issues that arose during the build phase could be dealt with quickly.

Joshua Pakstis

Client

We, at Mason & Mason have worked with Dave Supple, and New England Design for the past couple of years. We have known Dave and his crew through the local NARI Chapter for several years. New England Design is a contractor that we believe sets the bar for other contractors to try for.

Heather Clement

Real Estate Attorney

Great experience! We love our new kitchen created by NEDC! They were patient and very detail oriented. They held our hand when we needed it and we needed it often! We truly appreciated the professionalism of every member of the team and would call them again should we ever decide to undergo another renovation.

Charlene Sawyer

Client

Dave and the New England Design & Construction team were fantastic to work with. The company culture is the perfect mix of professionalism and approach-ability, and their communication was always open and honest. We worked through unforeseen challenges together, collaborated on ideas, and in the end we had successfully accomplished our mutual goals. I can say that New England Design & Construction cares passionately about their work and the well-being of their employees. This company is going places, and I'm looking forward to partnering with them again in the future!
