We love our clients!

We’re lucky to have tremendous clients. When we say they are "part of the Wellmade family" we mean it. If only we could have videos like this for every one of them.

It’s a sturdy, beautifully designed structure that adds both visual appeal and functionality to our backyard. We were especially impressed by the professionalism and hard-working spirit of the Wellmade installation crew.

This is a great company and product; the unit is far more impressive in person than we had expected.  The team was amazing to work with.  Nothing but a positive experience, and we're thrilled with our backyard office.  :)

I can’t recommend Wellmade enough. From first contact to finished product, the entire process took just 30 days (literally... 30 days ago I made my first inquiry via email) and the result is stunning.

What really sets Wellmade apart is not just the quality of their work, but how seamless and stress-free they made the entire experience. Everyone I dealt with was professional, courteous, and genuinely invested in bringing my vision to life. My new backyard home office is beautiful, functional, and I look forward to settling into my new space and enjoying it for years to come.

I'm blown away by how beautiful the Richmond is. The craftsmanship is superb and I wish I had more property so that we could get another from Wellmade. And, there's an incredible warranty that makes my purchase even more of a no-brainer. This was such an easy and satisfying process, they made everything from start to completion flawless, stress-free, and have provided me with a stunning piece of architecture that's the centerpiece of our soon-to-be backyard oasis.

Working with Wellmade has been a phenomenal experience. I checked out several companies and Wellmade was the only one that was truly transparent in their process and pricing.

What made this project even more special is how they integrated the shed with my existing outdoor deck. The crew came up with smart, creative solutions to make everything feel like one cohesive structure using the same composite decking and adding a clean step-up entrance that looks fantastic.

We got the Presidio Max shed and the Laurel sauna. We could not be more happy. They both look great and I was honestly shocked at how quick the whole process was.   The crew was incredibly hard working and considerate. The final product is very high quality.

This, along with really lovely looking buildings, is what sets Wellmade apart. They build the unit and they assemble the unit. The right hand talks to the left. The left hand talks to the right. And sales talks to project management who, in turn, talk to the guys onsite.

My wife and I are super-stoked with our Sunset shed from Wellmade. The entire experience was positive and we’re really pleased with the build quality and aesthetics of the shed.

The thing I want to emphasize most is the simplicity of the entire process. Most house projects we’ve done in the past have been friction filled. We’ve had to coordinate with various vendors, stress over myriad project details, and research materials without really having confidence in what we’re deciding. I can’t think of one house project that hasn’t had delays because of the difficulty in having the stars perfectly align for all the above (everyone is available, all materials are secured, all plan details are locked down).

Working with Wellmade on our shed was the complete opposite. My wife called it “instant gratification”. We had a couple simple video calls to walkthrough the space and discuss some details. I visited the WellMade office to look at the floor model. Once we decided to pull the trigger and schedule the date we filled out a simple spec sheet for things like wood color, window orientation, air conditioning, etc. When the start date came it was 5 and half days until the shed was done. The crew was amazing, hard working and not at all disruptive. When they finished there wasn’t a trace of construction debris which speaks volumes about their respect for a client’s property.

In the end, we have a quality home office / guest shed that aligns with our aesthetic sensibilities and we got it done with no stress or headaches. Thank you Masha, Andre and Sergey.

Absolutely in awe with our new backyard unit. We chose a Presidio to have a relaxing space where to listen to jazz records, read and enjoy a drink. It looks amazing and it was built in just 5 days! So impressed with the construction team - professional hard workers, respectful and considerate.The end to end experience has been absolutely amazing. Highly recommended!

We had a wonderful experience working with Wellmade. We went with the Presidio model to be used as a two person office and while we were initially concerned that it might feel tight for two workspaces it turned out to be quite comfortable. The project came out great and just as we had imagined. It looks exactly like it did in the pictures. We are also glad we went with some of the extra features like the heated floor and skylight.

We had the most wonderful experience with Wellmade. Everything was perfect, from start to finish. I am in love with my new studio office! The build crew (Sergey, Andre and Anthony) were so professional, hardworking and respectful. They worked so hard on the project and completed everything right on time. I highly recommend this company to anyone looking to add extra space to their home. It was such an easy process and they really took care of everything!

We are extremely happy with the Sunset shed and would definitely recommend Wellmade. The process went very smoothly. Our shed was finished in 6 business days. We were amazed at the quick progress each day. The crew started early and worked full days. They were very nice and communicated really well throughout the process. The shed is high quality and my wife and I are looking forward to working from home. It's nice to get a well designed product from a local Bay Area company.

We came across the website for Wellmade when searching for options of creating an outdoor office/gym for our house in the east bay. It was helpful that the company was from the area and we were able visit and preview some of the finished sheds nearby. were definitely impressed with the design and layout. It was a great experience working with team and we were impressed with how quickly it was built and assembled. Also, six months later after we noticed some issues with the skylights the team was very prompt and corrected the issue as covered by the warranty. Overall would highly recommend them
