“I can't say enough amazing things about the fine work by RRID and Roman Reiterer. He started with an incredible vision, maximized the space and really made an effort to learn about me and what would represent my lifestyle. He is professional, collaborative and inventive, especially when helping manage the budget. In the end, I have the house of my dreams. Every detail was thought out, and even things that I didn't think would have much impact, really contributed to the "feeling" of my house. I am proud to invite guests in to my warm, beautiful home.”

“My husband and I own a four unit apartment building in the Beverlywood area of Los Angeles that was constructed in the '40's. It was originally one of the "Co-op Style" buildings similar to the condos of today. Due to extenuating circumstances, it has been extremely difficult to update the building. HHDesign, with confidence and poise came to our rescue. Their professionalism and architectural expertise have turned a nightmare into a sweet dream. We were so impressed with their portfolio which is largely high-end and contemporary. This could have possibly been a stumbling block, however; you can imagine how pleased we were when, at their suggestion, they maintained the integrity of the building and style of the neighborhood. Even better yet, while honoring our budgetary constraints, they managed to give the building and grounds an incredibly needed facelift and artfully pulled the exterior facade into the 21st Century. We have had numerous complements from neighbors and friends and now have pride of ownership thanks to the tireless efforts and extraordinary service afforded by HHDesign. It is with the utmost sincerity that we recommend this highly efficient and talented team to the consumers of Houzz.”

“I commissioned Magdalena to design a piece of exhibition furniture that would serve as a display case would include areas where visitors could sit. The exhibition focused on Frank Lloyd Wright and the Japanese print. Wright, an avid collector of Japanese prints had curated several exhibitions in the early twentieth century at the Chicago Art Institute which included benches and pedestals that he had designed specifically for the shows. So, I was looking for an important element for our exhibition -- a work of art itself -- that would capture some of Wright's design aesthetic. I was thrilled with Magdalena's design. I also appreciated all the time she gave to convey her ideas to the cabinet builder who realized her ideas. I sought Magdalena's advice on another exhibition element in 2012. She gave crucial input regarding the design, structure, and placement of a viewing platform which allowed visitors to get a new perspective on a large-scale floor installation. Again, Magdalena's courtesy, creativity, and insights were incredibly appreciated. She has an amazing sensitivity to each project and gets to the core of it sometimes before I can even express it in words.”

“My experience with Audrey Sato was outstanding. She truly is a talented architect who has both great vision and is detail oriented; making the process of designing and constructing my fitness studio a fun and seamless one. I appreciated that she kept in constant contact with me, and was very hands on from design through construction. I felt comfortable asking questions and giving input, and am was very satisfied with the results. Pictures of the studio can be found on Facebook under 'The Dailey Method Calabasas'. Its a beautiful space. Clients of the studio rave about how beautiful, well lit, and comfortable the space is. And we owe it all to Audrey Sato Design Studio!”

“I hired Willis Daniels and Willisland Design to complete the redesign, expansion, and remodeling of 5 houses for re-sale. The results were extraordinary. I believe that the homes sold for significantly more than market and more than other projects in the area due to Willis' excellent ability to collaborate and his incredible design sensibility. I have hired him on many additional projects and have seen his work for others. HIRE WILLIS! He is passionate about his success, yes, but he is also passionate about yours. Willis is a great human and great designer.”

“Lisa Little worked wonders in our smallish Venice space. We had complicated needs and she found elegant solutions within a tight budget. We redid a kitchen from the walls out, extended it a bit, added a bar, added in a huge walk-in closet and staircase in the master bedroom, and reconfigured a guest loft. The latter involved enclosing a half-wall for privacy via rotating shutters that Lisa dreamed up and designed. The shutters rotate open when the loft is not in use and closed when we have company up there. This was a brilliant idea, brilliantly executed at not much cost. Lisa helped with fixture choice, color choice, and furniture choice, and worked closely with the general contractor and his subs. She exhibited great taste, a firm hand, and a keen eye on the budget. Recommended without reservation.”

“I'm scrolling thru Houzz and find pictures of our Bungalow that we own in La Quinta, California. It was designed by Sennikoff architects. We love this Bungalow it's beautifully done, we fell in love with the design of the home the first time we looked at it. It's magical inside of the home and outside of the home. Our family has grown and their visits are more frequent, we are in the process of building a new home in the same neighborhood, I so wish I had found Sennikoff Architects before we had started with someone else but I have a lot of his ideas saved which I am planning on using in the new home design.”

“Giovanni is creative, original, careful and considerate. I cannot imagine a better choice for your architecture needs. He did the plans for an apartment over our garage. When people open the door they literally gasp with surprise at the light, feeling of spaciousness (it's just over 450 sq ft), and unity of presentation. It's all down to him.”

“As a real estate broker, property manager and investment property owner for over 15 years I have worked with may designers, contractors and sub contractors (Good and bad) Mark at GCC Designs is at the top of my list of professionals I can trust to do the job right the first time. He shows up on time, articulates the scope of the job in a way that is easily understood and executes on time. The value he provides is right in line with the cost of the job. He is currently working on a major job in my personal home that is moving along just as planned.”

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 Los Angeles.

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.
