Our Process

Initial Consultation

We start with a consultation with you to discuss your vision for your home and determine the scope of work. We’ll listen to your ideas and make suggestions based on our knowledge and years of experience. 

Design Work

Once we clearly understand your project, we will create a plan and design that includes materials, a budget, and a timeline. We will work with you to make any revisions until you are completely satisfied with the plan. 

Permitting & approvals

Depending on how big your project is, we might need to get building permits and other permissions from the local government. BMW will handle this process on your behalf to ensure everything is in order.


Once the plan is finalized and all approvals are in place, we will begin construction. Our skilled workers will get the job done quickly and well, so that it meets the highest standards. We use high-quality materials and the latest methods.

Final Inspection

Upon completion, we will conduct a final walk-through with you to ensure that everything meets your expectations. We also offer a warranty on our work to give you peace of mind.


We want to have a good time working together. Let's meet over coffee or in your home to discuss your vision, budget & timeline. Depending on the project, we can discuss what additional sub-contractors (painters, electricians, etc.) will be needed.


Ben will come to your home to further discuss your vision for your dream space! This will involve taking measurements, discussing flooring, fixtures & everything in between. If you want to work with us on a kitchen remodel, this stage of the process will also include meeting with our designer. From here, we will take everything we've discussed back to the office and come up with an estimate that will be sent to you via e-mail.


Once you've given us the okay, Ben will get to work and you can relax! You can count on seeing him everyday from start to finish; unless, you only enjoy your Cape home on the weekends, in which case you can count on regular communication and project updates. As we near project completion, Ben works hard to make sure your home is left spotless and that we've brought your vision to life.

Benjamin Welsh,
Owner + Founder

I started working in the carpentry industry at 15 years old, helping my grandfather, by picking up used nails and straightening them so they could be used again. My love of the craft has evolved over the years into what it is today.

After graduating from Harwich High School, I began working for the Local 40 Union in Cambridge, MA. While in the Union, I captivated my time learning from career tradesmen. After working in the Union, I found employment back on Cape Cod, where I was able to further my knowledge in roofing, siding, framing, high-end trim work, and many other areas of the field. While I enjoyed these seasons of life, I ultimately felt called to owning my own business. In 2005, B.M.W Builders was founded.

As we head into the future, my family is committed to always putting God first, and we are excited to see how our vision for the business continues to reveal itself, through His grace. It’s as important to us as ever before, that our customers continue to feel our services are honest, reliable, organized, clean, and of the highest quality. I take pride in maintaining a hands-on approach, where you are comforted by seeing me on the job from start to finish. It is our greatest pleasure to make your visions for your home a reality, all while sustaining the unique character of Cape Cod homes.
