Saikley Architects
Architects in Castro Valley, CA
Average rating: 5 out of 5 stars20 May 2015
“We worked with Alexandra for a rebuild of our home, upgrading it from a 3bd/1.5 bath to a 4bd/3.5bath while adding a second floor and changing the layout of the house dramatically. We chose Alexandra based on two critical expectations: that she would be good to work with (after all, you spend countless hours with your architect on a very expensive project), and that she would share our philosophy regarding the importance of combining form and function in house design. We were very lucky to have chosen her. Alexandra indeed spent countless hours with us. She paid careful attention to our wishes and needs. She worked patiently through every detail of the house, helping us maximize not only our living space but also important functional aspects of the house. From beautifully located and proportioned stairs to storage for kids backpacks under an entryway bench and built-in cabinets to roof segments and their slopes, everything was thoughtful, detailed, and practical. Alexandra also showed great professional and personal skill in navigating the permitting process, developing a good relationship with the city’s planning department that allowed us to enjoy all the benefits of the zoning code. She was always ready to help and mediate successfully when issues inevitably came up with our contractor. She followed through with everything she said she would in an even, friendly, and professional manner. We are delighted with our home and, truth be told, also take joy in the many compliments we get from anybody who visits our home or even passes by it. Alexandra was wonderful and we can’t recommend her highly enough.”

Molinar Home Designs, Inc.

Average rating: 5 out of 5 stars4 May 2016
“We worked with Mark to design our new home. He spent the time with us to understand what we wanted. He incorporated our needs and requirements into various plan options and provided us with information on costs, pros and cons, etc. We had a very complicated project - Mark took the initiative to lead us through the planning a design process, acting at times as a project manager and presenting the plan to the city, other engineers and representing us when needed. He was very easy to work with and very professional. Building a custom home has significant challenges - Mark's help was instrumental in getting the project completed on time.”

“Barry and Wynn are talented, visionary architects who create beautiful works that both blend with the surroundings but also stand on their own in terms of individual character and timeless beauty. They have completed two commercial projects for me, one having one the prestigious Gold Nugget Award.”
Koch Architects
Architects in Castro Valley, CA
Average rating: 5 out of 5 stars29 January 2014
“I just completed a complete remodel of my San Francisco Edwardian flat and build out my basement. Joanne and her staff did a fantastic job. It started out as a kitchen bath remodel, but once the design process started expanded to include every room as we discussed how different spaces would be used and what I didn't like about the current space after living with it for 20yrs. Might as well do it right! Joanne's attention to detail, listening, and high ethical standards are unmatched. She would listen in the meetings and ask questions then come back with some ideas and sketches to get my reaction. She knew what I wanted without me even knowing it. She was also sensitive to the project budget which was important. I was able to complete the project within my budget. She was also key to working with the general contractor. She brought with her experience in projects of my scope / scale and working with different contractors and even her own remodel. This helped immensely. I look forward to the opportunity to work with Koch Architects again.”
Dotter & Solfjeld Architecture + Design

Average rating: 5 out of 5 stars1 November 2012
“We worked with Dotter & Solfjeld most recently to design an Italian villa on a hillside in Saratoga, CA. This was actually our third project together as they worked on an expansion and remodel of our previous house in Palo Alto as well. As soon as we bought the lot in Saratoga Russ and Wencke, of D&S, began studying the landscape, spending significant time at different points in the day to intimately understand the light, the views and the flow of the hillside. Russ and Wencke are experts at both exterior and interior architecture and design, and they are an amazing team! Once they felt they knew the property, they spent time with us to understand what we liked and disliked and then began designing our house based largely on Italian building principles of thick walls and simple, yet elegant, construction. D&S involved us in every step of the process and ensured we were completely comfortable with each phase of the design before moving forward. They totally went above and beyond the call of duty by diligently working with our planning department and even one neighbor. They were our advocates with the City and were clearly extremely well respected by everybody they interfaced with. During the building process, D&S worked closely with our contractor and foreman to ensure that the project ran smoothly and stayed on budget. Often times, there is tension between architects and contractors, but our contractor loved working with D&S. Some of our friends have also used D&S to design ultra modern homes...D&S is super versatile and we unequivocally and enthusiastically recommend them.”

“Nick Lee and his team at houseplans.com took us from a blank canvas for a property we purchased to a wonderful and beautiful house, guest house, barn, driveway, landscaping, and all of the other numerous things that turned our 14 acre parcel into a spectacular property. When we started, we had no electricity, no water, no septic, no driveway, no fence, no gate - just a beautiful piece of property. We did not even know where we would place the buildings on the property. Nick and his team developed the site plan, designed the house and the guest house and and placed the pool, driveway, landscaping, barn and all of the other items into a plan that flows extremely well. They followed the project through to completion and we are extremely pleased with the result. We cannot recommend this team highly enough!”

“Andrea designed a complete backyard remodel for us that involved extensive grading, hardscape and landscaping. The job turned out even better than expected and we constantly get accolades on the design. She chose the plants beautifully and 5 years out the yard looks better than ever and the plants have maintained and grown in even with restricted water use. I would highly recommend her and we plan to use her services again!”

John Lum Architecture, Inc. AIA
Architects in Castro Valley, CA
Average rating: 5 out of 5 stars3 April 2011
“We used John Lum Architecture for the complete remodel of ~1000 sq ft in San Francisco. John and team were fantastic to work with. Very creative yet good at listening to our thoughts and integrating our ideas. They understand how to both design a gorgeous contemporary space while still keeping it comfortable and livable. We depended on them with a lot of design detail recommendations such as fixtures, paint, tiles and they always had great suggestions that made the process much simpler and easy to manage. They are very professional, extremely responsive and timely. There were no surprises during the entire process including on deadlines and budgets. I would strongly recommend them.”

Architect or Architectural Designer FAQs
An architect is a professional who designs and creates building plans, ensuring the building is functional, safe, and aesthetically pleasing. They collaborate with clients to understand their needs and create designs that meet their requirements. Architects also consider building codes, regulations, and sustainability principles in their designs. They may oversee the construction process to ensure it aligns with the design intent.
If you are looking at a house extension or building a new home from scratch, chances are you are going to need the help of a residential architect. They have extensive knowledge of architectural design, construction methods and building materials, not to mention a strong appreciation of ergonomics – warmth, light and flow within a property. Architects will also be far more capable of seeing the bigger picture – carefully balancing aesthetic appeal with structural safety. With their local knowledge, your Castro Valley architect will also often help to obtain planning permission and building regulations approval.

    After choosing a residential architect, you will usually start with a consultation to discuss the project. Preferably at your property or building site where the work will be done. Give as clear a picture as possible of the kind of home you are trying to create to your architects. Chat through your goals, projected budget, scope of work, schedule and feedback, together with any very specific requirements you might have. They will explain their process to you alongside any other on-site visits up to and including the build stage, depending on whether they will be involved at that stage. From there they will produce the designs and plans required for your project.
    The cost of hiring an architect in Castro Valley can vary depending on the scope and complexity of the project, experience, reputation, and location. Architectural fees are typically structured as a percentage of the project’s total construction cost, ranging from 8% to 15%. For example, if a project has a construction cost of £500,000 and the architect’s fee is 10%, the fee would be £50,000. It’s advisable to discuss fees and payment structures with architects in Castro Valley during initial consultations.
