“The staff at Ohashi Design Studio helped me design my kitchen/living space. I wanted to open up our galley kitchen to be able to see our incredible view from the kitchen. They came up with a design I never imagined could work so well. Rather than just remove a wall, they moved the kitchen, changed it to a more functional shape and not only opened up the view, but made the living space feel like we were outside. I have been especially impressed with their level of service. They listened to my dreams and goals and turned it into a reality beyond what I'd hoped for. They were available anytime I needed guidance during construction and made sure the project was built down to the finest details. They helped me find a contractor and oversaw the bidding process. They helped pick out all the materials and finishes, even the paint color. I can't say enough about their level of expertise and professionalism. I worked with Dave and Alan.”

“This team was contracted to do the architectural work on an addition to my home. I sketched out the overall design. Nong listened and offered his suggestions. At the conclusion, his overall design and improvements when far beyond what I had envisioned. He walk through all the paperwork and time needed to get all the permits which allowed me time to take care of the family and talk about the new look. The project is still under construction, but I know my family and I will be happy with what we both (myself and Nong) envisioned.”

“Joe was exactly what we needed for our home remodel/addition project. We came in with lots of ideas but couldn't figure out how to pull it together and make it work. Joe was a great listener and quick to pick up on our style and needs, and in no time he was bringing solutions that we would never have come up with. In addition to being a real pro, Joe is very personable and a pleasure to work with. Highly recommended.”

“Tiffany is an exception architect. Her impeccable design sense, phenomenal attention to detail, and her ability to work magic with contractors and craftsmen is impressive. If you want a strong creative visionary with unmatched executional ability, Tiffany is the right architect. Very strong modern sensibility and has the capacity to lead projects across the architectural spectrum — she can do massive renovations and ground up work, to lighting and interior design, to landscape design. Highly recommended.”

“Christie was our architect for a very transformative remodel of our entire house. From a very dated 1970's styled house, that was built originally in the 1920's. She was everything we needed in an architect. Creative, responsive, and very professional. We would highly recommend her services.”
Lincoln Lighthill Architect

“We were in a unique situation - an opportunity to do some remodeling after a house fire. With the insurance budget parameters, we were still hopeful we could make some beautiful improvements to our home. Lincoln was the perfect person to partner with. He helped us envision simple, creative and impactful changes to our home that included opening our dining room up so that the best view in the house (from a kitchen window) was visible from the living and dining rooms. He listened to our wish to host larger dinner parties and created a movable ceiling light, so it can always be centrally positioned regardless of how long our dining room table might be. He worked with our more conservative contractor and helped advocate for our ideas, finding modern, sleek textiles and cabinetry that immediately increased the value of our home. A back hallway became a pantry; a small closet in the bedroom was expanded to become a little walk-in closet. We built in a post-modern ladder to the attic, an interior wall window to bring more light into the bedroom and many other details we wouldn't have thought about. Lincoln's vision and experience elevated our home and it turned a disaster (fire) into a huge opportunity! I highly recommend collaborating with Lincoln on your next project, big or small.”

“Jeff Potts at SDG designed us an incredible, award winning guest house! What I particularly like about Jeff is his open and approachable style. We've worked with many architects over the years and many simply don't want to listen to the client. Jeff listens and then delivers a design beyond your expectations. I would highly recommend working with them.”

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 Saint Helena.

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.
