We recently had the pleasure of working with Michael Monahan and his team at Monahan Design Build, along with Ingruids Designs, for the construction and interior design of our new home. From the very beginning, Michael and his wife demonstrated an unparalleled commitment to craftsmanship, creativity, and customer satisfaction that truly set them apart.
The process began with Michael's keen understanding of our vision. He listened intently, offering insights that not only met but exceeded our expectations. His expertise in design-build was evident as he seamlessly blended architectural innovation with functional design, ensuring that every detail was both aesthetically pleasing and practical for our daily living.
The construction phase was a testament to Michael's leadership and the skill of his team. The work was executed with precision, and the attention to detail was remarkable. Michael was always on-site, overseeing operations, which gave us confidence in the quality of the build. His hands-on approach meant that any concerns or changes were addressed promptly and thoughtfully.
Ingruids Designs, led by Michael's wife, brought an artistic flair to our home's interior. The design choices were both sophisticated and warm, creating spaces that felt uniquely ours. The collaboration between Monahan Design Build and Ingruids Designs was fluid, resulting in a cohesive look that flowed from the exterior architecture to the last piece of furniture placed inside.
Throughout the project, communication was clear and consistent. Michael made sure we were informed at every stage, which alleviated any stress and kept us excited about the progress. His professionalism was matched only by his passion for his work, which was infectious and made the entire experience enjoyable.
The final product is a home that not only meets our needs but also reflects our personality and lifestyle. It's a space where we feel both proud and comfortable, thanks to the dedication and talent of Michael Monahan and his team.
We highly recommend Monahan Design Build and Ingruids Designs to anyone looking for a home that is not just built, but crafted with love and expertise. Michael and his wife have not just built us a house; they've created a home where memories will be made for generations. Thank you for turning our dream into reality with such grace and excellence.

We had the pleasure of working with Michael Monahan from Monahan Design Build and his wife Ingrid from Ingrids Designs to build my dream home in Devon, Pennsylvania. They are a talented and professional team who delivered exceptional results on time and on budget.
From the initial consultation to the final walkthrough, they were attentive, responsive, and creative. They listened to my vision and preferences, and offered valuable guidance and advice along the way. They also communicated with me regularly and kept me updated on the progress of the project.
The quality of their work is outstanding. They used high-quality materials and craftsmanship, and paid attention to every detail. They also incorporated some unique and stylish features that made my home stand out from the rest. The design and layout of my home are functional and beautiful, and reflect my personality and lifestyle.
I am very happy with the outcome of my custom home project. I would highly recommend Michael Monahan and Ingrid Monahan to anyone looking for a custom design build contractor and interior designer. They are the best in the business .

I highly recommend Monahan Building to anyone looking for a custom home builder. You will appreciate Michael Monahan's craftsmanship and integrity. He was a pleasure to work with from the very beginning. Michael helped us work through many challenges we faced with approvals before we could build our custom home on our own land. We also had a condensed timeline for building due to a nature conservation requirement and they worked hard to ensure we could meet the aggressive timeline. He was patient and understanding with many design changes that we made along the way to ensure we got it right. Michael and his team worked with us to build the home that was perfect for our family. We love every aspect of our new home thanks to their attention to detail. Even after their work was complete, they have continued to provide support to us ensuring that we are fully satisfied and helping to resolve any questions or concerns along the way. Michael Monahan and his team has been excellent to work with throughout the entire process. Our family enjoyed the design and building phases immensely thanks to their team of qualified, knowledgeable and caring employees.

By Ginger C.December 30, 20152500 sq ft addition and renovated our entire home$600,000225 daysBEST BUILDER EVER
We had a renovation and addition done on our used to be quaint 2400 sq.ft. home. We looked in to moving or building new and between the real estate taxes and the problems of possibly changing schools and neighborhoods that would effected the children aided in our division to stay and renovate/ add on. We pretty much doubled the size of our home and renovated the sq.ft. of the existing home. We are very happy with the end result. The process wasn't as difficult as I though it would have been. I definitely think that us hiring Monahan Buildes was the best thing we could have done. They weren't the cheapest bid and they weren't the highest bid. But at the end of the day you get what you pay for. My most favorite rooms in our home I would have to say is our kitchen and master bath and suite. I love my closet as well! I finally have somewhere to put my shoes :)
We are very happy with Monahan and his people. I couldn't recommend them highly enough. -

Mike Monahan and his company recently completed a addition and extensive renovation to our home. Mike had done work on other homes in our neighborhood, that's how we found out about him and his company. I am righting this to help other folks looking for a great contractor that might not know one. The most important thing about our job was that it was done on budget, time and it was 100 percent complete and we were completely satisfied. If you are looking for a contractor and don't know one, Monahan builders would be the company myself and my neighbors would recommend.

My husband and I recently finished a project with Monahan and his team. We were extremely satisfied with the quality of the work and the length of time it took to do the project. If we were to ever do another project we would certainly use them again. There is somethings in life that aren't dependable. If there is a company you can trust and count on it would be Mike Monahan. Thanks again mike for the job well done.

A THIEF.
You MUST avoid Michael Monahan, aka Michael Monaghan, like the plague. The positive reviews are stale and DO NOT reflect the deceitful and criminal manner in which he conducts "business" today. We paid in excess of $100k (just under 50%) of the estimated cost for an addition to our house before he left us high and dry with only about 10% of the work completed. Bounced checks to our Township for permits, didn't pay subcontractors, barely met with us during the short time he acted like he was going to have our addition built instead of simply RIPPING us off. Do your homework and look deeply into the background of this thief. Including us, there's at least three other clients suing him in civil court and two of those clients are out a total of approximately $1million dollars. Don't be fooled by my rating. It's less than ZERO.
