“Tony and his team did an excellent job . They expanded my master bedroom including the bathroom and a walk in closet. I am not the easiest customer. I had so many questions, and Tony was patient with me every step of the way. They were very thorough and competitive. They were constantly updating me and going over the process . The entire experience was great!! Always on time with a great attitude. I want to say that I worked with a few general contractors over the years and it is difficult to find a good one that actually keeps you updated. If you are looking for a good contractor, look no further! I am very satisfied!!! Thank you Tony and Nuhome! -Clement”

“Tom & James, our project managers, did general contract work for me in the kitchen and bathroom. They did a superb job managing the project. I was very pleased. His team worked on the floors, counters, painting and plumbing. 
My favorite is the shower, and bathroom/kitchen cabinets.”

Average rating: 5 out of 5 stars5 October 2016
“We were referred to Ori at LU construction by our family that hired them to remodel their kitchen a while back. Ori outlined the project steps for our kitchen remodel and presented a competitive quote for the job. The entire crew was professional, resourceful and efficient. During the entire remodeling, Ori was responsive and communicative to any of our concerns and he was always available to meet with us as needed. He demonstrated professionalism in executing any changes to the plan. Overall, we could not be happier with the new kitchen that he remodel for us. We lived at the house through the construction and it was honestly much better than we thought it would be. We trusted Ori and it was worth the trust. Many Thanks for all the hard work and to the people that did the actual work at our house! We've already recommended them to others looking for a dependable contractor who delivers quality work and timely execution.”

“After getting several estimates from different companies, I was fortunate to find ON Design & Remodeling. I had no idea what I wanted to do but ON Design & Remodeling came in, took a look at my kitchen, created a 3D Design that was mind-boggling to say the least. The reality of it is, they came in, completely demo’d my boring, old kitchen and gave me the kitchen of my dreams! And the hood itself is just a work of art. They exceeded my expectations at every turn. Literally impeccable workmanship! My kitchen turned out so amazing, we begin demo on my master-bath, master bedroom & closets in 10 days. I can only imagine what they will do there!”

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 San Martin.

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.
