Clear Cut Design, LLC
House Extension Professionals in Portsmouth, NH
Average rating: 5 out of 5 stars21 February 2024
“I used Clear Cut Design for a wet bar in our dining room and built in cabinets in our powder room. They both came out beautiful. His work is amazing quality and excellent craftsmanship. I appreciate his attention to detail and helpful feedback when I had questions while designing the built ins. He was extremely professional and personable throughout the entire experience. I would absolutely hire him again for my own home or my interior design clients.”

Average rating: 5 out of 5 stars4 September 2015
“George Trojan is a gifted and talented professional. He excels in both general contracting of large building jobs as well as being a detailed perfectionist in finish carpentry projects. His work ethic and good humor along with his desire to please the customer make him a delight to work with. Working as the project manager in the rebuilding of my home after a fire, I found him easily accessible and available and immediately responsive to my questions, requests, and suggestions. The advice he provided on design was superb and his ability to grasp and handle a large number of challenges and problems made the job go quickly and smoothly. His practice of working through and completing one job before taking on another made me, as the customer, feel like I was his first and only priority. I would say that his character and integrity make him a contractor you can depend on and put your trust in. I recommend him without reservation.”

“I've personally hired Haven Hill Builders several times over the past 8 years and they have always done an amazing job. They are insightful, personable, timely and diligent. I'm very particular and every project has been completed to the utmost of quality.

Powell Builders, LLC
House Extension Professionals in Portsmouth, NH
Average rating: 5 out of 5 stars21 March 2017
“To build my retirement home, I was looking for a builder that I could trust. After interviewing several, I knew immediately that I found what I wanted when I met Paul and Luke Powell, and that I could trust them to do the right thing to build my house while I continued living and working several states away. Professional and knowledgeable only begin to describe the Powells in the way that they conduct their business -- I came to view them as I would family, and I could trust them as if they were. The quality of their work is unsurpassed, and they will do all that they can to keep your project on time and within budget; and when issues occur along the way, you can depend on them to let you know, and to provide to you options to continue forward with your vision of the finished product. I could not have made a better choice in hiring Paul and Luke Powell to build my retirement home. I give them my highest recommendation.”

Average rating: 5 out of 5 stars24 March 2014
“We chose Maine Coast Builders, a company with many years of experience in constructing coastal homes. From the rough construction to the detailed finish work, we found the MCB craftsmen to be highly skilled and able to handle the complex design work flawlessly. Their talent is evident in the details of both the exterior and interior, showcasing expansive cathedral ceilings with inverted recesses. A hand-constructed staircase, built in cabinetry, window seats and mantles, all were fabricated with care & precision. Jeff Jones supervised the construction, coordinating the various craftsmen and kept within the planned timeline. He was always available to explain the process of each phase. - Rich & Linda Torossian”

“Nobleport was extremely thorough in their work. They took us through each step of the process and explained our options. They helped us find the most cost effective, long term solutions to the repair work we needed done. They showed us what they were going to do before they did it.

Builder 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 Portsmouth.

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.
