William Adams Process

Effortless steps for exceptional outcomes

Initial Assessment
Our design starts with an assessment of your space, measurement verification, and a lifestyle questionnaire. We then create initial designs, including sketches, CAD drawings, and material selections.
Design Detailing & Collaboration
Following layout approval, we detail millwork, calculate quantities, estimate costs, and create a material schedule. We gather samples, initiate pre-construction plans, and coordinate with third parties.
Design Refinement & Coordination
We adjust material schedules to fit your budget, refine designs, and prep construction sets. We also submit & manage permits and assist with contractor, engineer, and vendor selection.
Design Approval
We check and track every project item, sharing a comprehensive finish guide with contractors. Each item is inspected, and we swiftly handle any on-site surprises, from returns or replacements to quantity adjustments.
Construction Kick-off
Demolition and construction kick off 2-4 weeks before the most extended lead time items arrive. WAD visits the site during framing, electrical, and plumbing, and periodically during finishing and installation to ensure the design is executed per our planning.
Final Walkthrough
We team up with your general contractor for a thorough walkthrough to check installations, finishing materials, and fixtures.


Does my project have to be of a certain size or budget to work with you?

No, your project whether it be paint & pillows or an entire home remodel is of great interest to William Adams Design.  We work with a variety of budgets and project sizes, from the furniture layout of a room, to a single bathroom remodel and as large as a complete home renovation.

When is the best time to engage with you on my project?

Now!  We recommend getting involved with us during the early stages of your project. Our goal is to provide a complete design package to be presented to your or our recommended General Contractor to receive an accurate quote for the scope of work to be completed.

Do I need to hire an architect for my project?

This is really dependent on the overall scope of the project.  For remodels such as kitchens, bathrooms and interior renovations, an architect is often not necessary. We can provide the necessary drawings that both the General Contractor and the City may require.  If necessary, we will help engage with a structural engineer.  William Adams Design functions as your interior architect and does not have the capability to execute drawings for additions, new builds or major exterior changes.  However, we will help you engage with the appropriate architect if one is necessary.

Do you have a specific style or aesthetic that I need to adhere to?

William Adams believes that collaboration with you is the key to a successful project. It's important that both you (the client) and William realize a shared vision. We will work as your both your guide and your collaborator, to achieve a space that embraces your aesthetic and lifestyle.  William Adams is known for designing spaces that are 'fresh traditional' and also warm mid-century modern.

How do I find out what your services cost?

As each project is uniquely special, it's best to contact us directly.  We are looking forward to discussing your project with you!

What is your company’s response & protocols in response to COVID-19?

We all know that this year has been a challenge, especially during a pandemic. William Adams Design is doing its part to keep our staff & clients safe. We are following the guidelines established by the CDC, the State of California and each county that we are working in, per the county’s health official regulations.

— Rodrigo F.

Will designed three different plans for a complete home remodel. After choosing a plan, Will made sure the project went as planned. The results were beautiful. We are very pleased with our updated and stylish home. The kitchen and bathrooms are gorgeous and timeless . He also followed up on any concerns we had and communicated with our contractor. I would recommend Will Adams Design.

— Karen L.

Will is amazing! We have done 2 projects with Will (a bed, bath and closet remodel and kitchen/yard renovation that's yet to be executed) but we have been SO happy with the partnership with Will on both. He listens, is collaborative and has an incredible ability to visualize what you're looking for. Will takes feedback and will tailor his design to your budget while providing incredible finish options that honor the original design of your home in an area where homes are so architecturally varied.

I'd highly recommend Will for any and all design needs for your home and/or yard.

— Jordan L.

Will is incredibly talented and help us achieve the kitchen of our dreams. He was incredibly responsive, and had incredible solutions when we discovered a few hidden surprises. Can't wait to have him help us redo our bathrooms.

— Mark T.

Will did an AMAZING job on our recently remodeled bathroom. The first time I met Will was virtually, while he was showing us a mock up of what the bathroom was going to look like. I INSTANTLY felt like I was on an episode of Fixer Upper with the renderings. However, he out shined Joanna Gaines.

From start to finish, Will was professional, congenial and timely. We had an issue with a mirror being delivered broken (which we didn't know upon delivery as it sat in its box until we needed to put it up). Will instantly started looking up replacement mirrors that would fit with the design and aesthetic of the space. He was able to get us a FULL refund on the damaged mirror as well as get the new mirror ordered in time so that our project could finish in a timely manner.

All in all we had a great experience with Will and plan to use him for future home renovation projects and you should as well.

Headline: Budget-conscious home-owner, first time hiring Design Firm

I've never hired an Architectural Designer before and have been morally opposed to it ever since I became a home-owner in 2006. It seemed pretentious and unnecessary, in my opinion, since my father and I had successfully renovated three houses previously (nothing fancy.. paint, re-flooring, roofing, landscaping, curb appeal type stuff for resale). I've begrudgingly hired a General Contractor 2-3 times for permitting and city compliance for previous projects but felt taken advantage of since fees were so unpredictable and open-ended. After meeting some of Will's clients, several of which are repeat customers (which is a rarity in this industry, I learned), he was able to help me with a variety of vital investment decisions with my properties:

1. First at a home I own in San Luis Obispo around permitting and zoning an ADU, and significantly improving the livability and design of my home's kitchen using his tradesman discounts to forecast a budget I was comfortable with.

2. Second, redesigning my current San Francisco apartment's living and dining room; paint + wallpaper selection, furniture upcycling/reuse so I didn't have to spend unnecessary $, and because he had some extra time in between site visits, he personally educated me on installing a new chandelier fixture, so I didn't have to hire an electrician. (My building was built in early 1940, so the wiring is super old/complicated.. I never expected an Architectural Designer to handle something like this.. GC/electricians quoted several hundred dollars previously).

If you want your home to be beautiful, functional to you and your family's needs, up to code - or if you are simply trying to increase your home's appraisal value drastically, call Will. The ~20 years of experience focused specifically on property renovation shows, and the value versus the cost is far greater than I anticipated after researching many other firms.

— Brandon S.

Will was a pleasure to work with on my kitchen ….

He was sensitive to the sense of architecture and having the kitchen feel as if it “belongs” as well as the functionality of the design … I highly recommend Will - he is extremely talented and professional.

— Jennifer W.

Will helped transform our dated kitchen into such a beautiful useable space. He was so easy to work with and incorporated our lifestyle needs into the design.

— Michelle Van R.

Will came highly recommended by multiple neighbors on our street. He didn't disappoint. He came up with an awesome solution for our downstairs floor plan as well as a kitchen we'd never thought would work with our former space. He has great taste!

— Eric K.

I have been a client of William Adams Design for 10+ years and have completed multiple projects with Will and his team of professionals. The process is unique and client-focused - collaborative, no surprises, and enjoyable. Will believes that design should combine beautiful design with function and be customized to the way the clients live. The process Will and his team use delivers construction-ready designs with sourcing (materials, appliances, etc. with pricing). I was able to complete the process with Will and have time to plan, procure materials, cabinetry, and appliances so that I was ready to go when it suited by timing and budget. The designs also gave me bid-ready plans for potential contractor bids and supported negotiating with contractors for fixed fee. I also did not fall into the trap of waiting on materials (or relying on contractors to source) and prolonging construction. I highly recommend William Adams Design for creating a beautiful and liveable home.

— Amy A.

My husband and I used Will to redesign our master bath which was hideous, small and non functional. Will exceeded our expectations with the design. From start to finish he was professional, communicative about the process and quickly responded to my questions. He and his team were punctual and easy to work with. We can’t wait to work with Will again on our other projects.

— Erin S.

Every day we get to enjoy the work of William Adams Design. Spending so much time at home during the pandemic meant that our home space effectively became our life space. The design work on our kitchen allowed it to be the functional kitchen we needed for the umpteen loaves of bread we baked...but the light-filled nook also served as an office, therapy space and meditation room. :)

Our Master Bath, also redesigned by William Adams Design is like a resort spa and many days these past two years we've really needed a staycation - this atmosphere made that possible.

If you want to remake your spaces into the home/office/sanctuary that you need for your next stage of life, look no further than William Adams Design.

— Rosemary J.

Will is like a breath of fresh air. He sincerely is design-minded, however also able to problem solve. I get the honor to call him my client - and he's my company's go-to designer. I have referred numerous clients to his firm and will continue to do so.

— Melody H.

Will was fantastic. He was creative with the design, always responsive, and delivered a great finished product. He transformed the space and we couldn't be happier!

— Bobby W.
