Keery Design
House Extension Professionals in Portsmouth, NH
Average rating: 5 out of 5 stars23 August 2015
“Keery Design planned my retirement home in Scituate, MA on the same lot of land owned by my daughter and son-in-law. Because of zoning regulations the house was limited to 750 square feet. If anyone had told me prior to David's design for my home that I would be happy in 750 square feet I would not have believed it. But I am thrilled with the design and the livability of my home. Every square inch is usable space. There is a loft built in over the kitchen for my grandchildren's visits. The house is open and airy with gorgeous window views of the blueberry bushes and the woods at the edge of the property The angles in the home and the high ceilings create a feeling of space.. The house was designed to coordinate with my daughter's home and it does that beautifully. David worked throughout the process with the builder and offered many wonderful suggestions about material and accessories and that helped me to stay within my budget. The result is a home which I love and visitors rave about when they come. Beautiful space creates a feeling of contentment and peace. This space does that for me. I couldn't be happier with the design and building of my home.”

House Extension Professionals in Portsmouth, NH
Average rating: 5 out of 5 stars29 April 2018
“AECm has been a pleasure to work with. I hired them to design a new home with enough space to accommodate our family and growing home-based businesses. They made the entire process very easy. We provided our “must haves” and “wants” and in a relatively short period of time, they provided us with a unique concept that we would have never come up with on our own. The outside of the house is amazing and not your average cookie cutter house. From there, the floor plan was developed to not only accommodate our needs but to make the most efficient use of space. To get everything we wanted and have an energy efficient home is a dream come true. Every aspect of the house is perfect and I can’t thank Tim Nichols enough for making it happen. It’s absolutely beautiful!”

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 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.
