Featured Reviews for House Extension Professionals in Cambridge, MA

Alan Christ Architects LLC
House Extension Professionals in Cambridge, MA
Average rating: 5 out of 5 stars4 January 2018
“Alan designed a beautiful addition for me. Alan was amazing from beginning to end. Alan is very knowledgable about his field and carefully explained the parameters of what could and could not be done with my project. He listened patiently and was willing to do several re-dos of the design providing me with different and creative options. Alan went over and above of what is expected making several visits to the planning and building department to ensure we complied with the town and building regulations. He also made numerous site visits. He is utterly reliable, prompt and willing to be creative to stay within your budget. Alan isn't happy unless you are happy and works tirelessly until that is achieved. I would highly recommend him.”

“Joe Fournier did some great architectual design work on two large projects we did. A large remodel on one property and an almost complete rebuild on a second property. Joe acted as GC on the second job and did a wonderful job keeping things moving, helping us get good decisions made in a timely fashion and working closely with all the trades to ensure the work was coordinated and of high quality. The transformations to our properties were hugely successful and Joe was instrumental in helping us get to a place where the homes work so much better for our lifestyle. Highly recommend Joe's work (and already have several times).”

“It's been an absolute pleasure to work with SLS Architecture (former DaCruz Segal Architecture) on our extensive house renovation project. We were delighted with the vision and aesthetic they brought to the project. They are impressively creative, thoughtful, very professional and passionate about their projects. Their extreme attention to detail enabled us to achieve impeccable results. Looking forward to our next project with SLS Architecture (former DaCruz Segal Architecture).”

Average rating: 5 out of 5 stars3 April 2014
“We did a complete gut and remodel of almost our entire home, and Aimee did all of the design work, from conception to execution, including the kitchen and great room, two bathrooms, 3 bedrooms. We had the best experience, from start to finish. She got to know us and had an amazing understanding of our style, and was able to make suggestions and streamline the whole process. We couldn't be happier with how it came out. We get continuous compliments from everyone who sees our house, particularly on the kitchen, and have recommended Aimee and Jaz Design to everyone we talk to.”

Average rating: 5 out of 5 stars28 August 2023
“Michael was a joy to work with for our remodeling project. He was patient, responsive, and highly collaborative throughout the whole process. His creativity and design acumen helped us to solve some complex layout problems, and to connect the indoors and outdoors in an original and impressive way. In addition to the overall plan, he also designed smaller components that needed his knowledge and attention to detail, including a lighting scheme, shelving system, and custom outdoor furniture. He helped us to research unfamiliar building materials, and provided ample design ideas that we shared using an online file folder. The end result was a space that works beautifully for us and is superior in every way to what we had before. Michael's familiarity with the remodel process from soup to nuts made it possible for him to interface effectively with all the contractors, vendors, and specialists (such as the structural engineer that we needed). He made timely suggestions that improved their work and guided our choices as things unfolded. I highly recommend him for any significant remodel project like ours and smaller jobs that require smart, elegant, cost-effective ideas.”

“We worked with Foley Fiore Architects on a custom home in a suburb west of Boston. As the general contractor's site supervisor I worked very closely with them and can attest that their approach is collaborative, solutions oriented and client driven. Their staff is highly professional and pays tremendous attention to detail and client service. We look forward to working with them again.”

“We have worked with Carl Solander on several projects (large and small) on our 3 family in Brooklyn, NY. He helped us with a full basement reno, 2 bathrooms, and outdoor deck work. We were extremely impressed with his comprehensive knowledge of materials. His designs are modern and beautiful and a pleasure to live in. And lastly, he is awesome to work with- great listener, great work ethic. We have recommended him to several friends who have all been very happy. We are about to use him again on our biggest job yet and are so excited to see the results.”

“Glen is absolutely wonderful. I can't wait to hire him for my next project. He has such great new ideas”
Douglas Okun & Associates
House Extension Professionals in Cambridge, MA
Average rating: 5 out of 5 stars31 May 2020
““You can't turn a sow's ear into a silk purse” - Maybe not, but Doug Okun and Associates did succeed in turning what was once attic space in a Victorian house into a third floor modern suite. Indeed, by moving walls, and re-configuring space, he managed to create two bedrooms, a bathroom, a sizable closet and a gracefully curving staircase from the second floor. What had been dark, even claustrophobic, rooms became the bedroom level of a two story condo unit in a very desirable location in Somerville, Massachusetts. Doug worked closely with his contractor to see us through an at times arduous permitting process. In every respect he was indispensible.”

Average rating: 5 out of 5 stars6 May 2013
“Diane Lim brought fresh, creative, thoughtful design skills to a tricky remodeling project that involved joining two very different condos in a Back Bay building into one unit. We had worked with her once before on a kitchen remodeling project, which turned out great! She knew our style, which is why we went back to her for this most recent project. Throughout both projects, she was highly professional, knowledgeable, and on-time with her work. With an open and positive outlook, Diane listened to our ideas, and communicated well with our contractor. I have already recommended her to friends, and wholeheartedly recommend her now..”

Architect or Architectural Designer FAQs
A house extension is a construction process that involves expanding the footprint of your existing home. This could be extending outwards, either to the side or rear of the house, or upwards by adding another storey. House extensions provide extra living space and can significantly increase the value of your property.

House extensions can be categorised based on direction, structure and function. The main types include rear extensions, side return extensions, wrap-around extensions, and double or single-storey extensions. More specific ones could be kitchen extensions, loft conversions, basement conversions, garage conversions or conservatories. Select the type that best suits your property and meets your space needs, if you are unsure, speaking with a local home extension builder in Cambridge.

Generally, house extensions are worth the investment. They provide additional living space and can dramatically increase the resale value of your home, often covering the initial investment cost. However, plan carefully and choose a reputable house extension builder to ensure a high-quality build that will add value to your property.

The cost of a house extension can vary significantly based on several factors, such as the size, complexity of the design, quality of materials used, and geographical location. However, as a rough estimate, a single-storey extension can range from £1,000 to £2,000 per square metre, whereas a two-storey extension can start at around £1,500 per square metre.

Planning a house extension involves several stages, including idea generation, design, planning permission, and construction. Consult with a house extension architect to create a design based on your needs and budget. Ensure to check with your local council about planning permissions. Finally, choose a reputable house extension builder to bring your vision to life.
