John and his team did a wonderful job with building our shed and pergola. They are super communicative and easy to reach if you have questions or concerns. If you have concerns, John will address them right away. The building process was explained to us every step of the way. We had a weirdly shaped concrete slab and they still were able to make it work. They were able to finish the shed and pergola in about 10 working days without cutting any corners. Our shed turned out super clean and just what we wanted. We're very happy with their work and we love our new backyard oasis. I highly recommend John and his team if you are looking to build a backyard space. read more

I have nothing but the highest praise for Shed Mania. John and his whole team was a pleasure to work with. Not only was John great to work with, his whole team was so professional, hardworking, humble, and very respectful every day they are here. They built a loft shed and also restored our patio and decks as part of the project. Given the pandemic, I will be working remotely permanently, so having this office shed built is a dream come true! I now have a beautiful space to go to daily that's truly mine. And the loft is the best part! It's been turned into a reading nook for my daughter, and can be used as a guest bed when needed. The whole process including deck work was 2.5 weeks. I can't believe how fast and efficient they were. The pricing was reasonable and fair as well. If you are even remotely considering or curious about getting a shed, just give John a call and get that conversation started! He would be more than happy to answer any questions you may have without being pushy or agitated. He's someone you can trust, that's the most important thing you can ask for when looking to hire a contractor. read more

I had initially reached out to John after a bad experience with another local shed company here in the east bay. Upon my first call with John he was immediately understanding, knowledgeable and communicative. During the construction process John was involved every step of the way, and proactively kept me up to date, since I was out of town during the first phase of construction. He even looked after my cat! The end result was amazing, and the process seamless. John and his partner Song are true professionals and I would not hesitate to recommend them and their work to anybody. My only regret is Shed Mania was not my first call. read more

I looked at all the local as well as national shed businesses and decided to work with Shed Mania. The owner, John, is very responsive and worked collaboratively with me to help design and realize my office shed build-out, which had to be a bit custom due to a need to adhere to zoning rules. While Shed Mania wasn't the cheapest option I looked at, it also wasn't the most expensive, and with projects like this, the communication and accountability part is SO important. (That said, I still came in under my budget.) Lots of other companies will only go halfway - they'll do the exterior, but no electrical or interior finishing. Shed Mania will complete your project end-to-end and alleviate the headache of finding separate contractors to do the other work. I'm a real stickler for details, and John worked with me on everything, down to the fit and finishes. He estimated the amount of time it would take to complete construction, and still came in early despite a moderately sized hiccup with my pier foundation. His crew showed up on time every morning at 9am, and wrapped up promptly each day before 5pm, leaving the work site clean. They were a bunch of very friendly guys, and were respectful about sharing the space when we needed to be in the yard at the same time. John did a great job of anticipating the things I would be detail-oriented with, and checked in with me whenever there was a chance of mismatched expectations. I appreciate that he gave me the space to bring in my own ideas to this design. Highly recommend if you're looking for a finished shed structure! I've been using mine as an office for the past week and it's been perfect! read more

I'm very pleased with how John and Song handled the whole construction process. They are responsive, easy going and reliable. My music studio was built from scratch in less than 3 weeks.

The only regret I have is waiting for this long to finally create this she-shed! Oh how I wish I had this during early pandemic. I suffered a year of working at home with my kid zooming next to me in the living room. This was the best present I bought myself! John and his team at Shed Mania were all very professional and courteous. They came early in the morning Monday to Saturday and got it done in less than 2 wks. I inspected the place and they immediately addressed any concerns we had. They cleaned up every single thing before leaving too, including the branches they cut off our tree to make space. I highly recommend them to my friends. read more

We love Shed Mania and would recommend them to anyone interested in building a shed for their home. We needed more room and decided we wanted a new shed in our backyard. Living in San Francisco this meant some specific zoning issues. We talked to several contractors and their quotes were too high or did not allow us to customize the shed to what we wanted. We found Shed Mania on yelp and connected with John. John got back to us quickly, gave us a fair quote and allowed us to make modifications and customize to what we wanted, including installing solar. He was incredibly responsive (even while on vacation!) and provided incredibly helpful advice throughout the process. Our shed is 12' x 8' to stay within the legal zoning rules of San Francisco. The odd size meant some out-of-the-normal workflow for John and his crew, but everything was handled well and within a timely fashion. We also had a small issue of a neighbor calling the City on us. We met with a City Inspector and the issue was resolved quickly. John's crew were hard-working, courteous, and professional. Song, their lead contractor, was always super responsive by text and easy to work with. They completed our shed in roughly three weeks. They even worked weekends when our shed was put on hold for a few days due to the City being called. Overall, the experience was great, and we have a beautiful shed that we love! We strongly recommend John and Shed Mania. read more

Let me start off by saying that I typically do not write reviews. With that said, John and Song have been nothing short of amazing throughout the entire process from the first call through to helping me out with things months after the completion of the job. Literally everything that I asked about was answered and taken care of no matter how small the detail was. I can be a detail obsessed kind of guy, (to put it lightly), and I simply cannot praise them enough for their skill, customer service, attention to detail, and every aspect of the experience. I've made it a point to tell all of my neighbors and friends to check them out, going so far as to invite neighbors in to check out their work. Not to belabor a point, but I think that they are really on to something. Many of us working from home typically use a bedroom to convert into office space. This isn't the most practical if you have children, etc. Having a separate space means that I have a space that was designed for work. This is a major luxury, and I'm happy as can be with it! read more

I needed to build an office shed for remote working and researched a ton of options. The prefab choices were too expensive, not customized, and needed a separate crew for assembly while the HomeDepot sheds were not cutting it. Then I found Shedmania on Facebook. The owner worked with me to design the best studio option for our home with the right price. My new office was completed ahead of schedule. The quality of construction is top notch and it is a beautiful new addition to our property. I highly recommend Shedmania! read more

John and Song and team exceeded expectations. They were always easy to get ahold of, answered any questions we had, and got the project done ahead of the original schedule. The crew was always on time and hardworking, working 5-6 days a week, and returning promptly for the final follow up items. The quality of the shed is very nice!

The Shed Mania team is a very well run operation that excels at communicating with the client.

My wife and I needed an office shed as we were converting her current office into a nursery. We were so happy and delighted to have found Shed Mania. John, Song, and their entire team did an amazing and exceptional job. The entire process was quick, smooth, and they delivered quality work timely. John and Song were quick to respond via phone, email, and also set up a Zoom call to make sure all the details were exactly what we wanted. We can't thank them enough for getting the project done earlier than expected as we were expecting. We had looked at other options, however we didn't feel great about them until we found Shed Mania. We are extremely happy with the outcome. We highly recommend and will strongly consider them for projects in the future. read more

John and Shed Mania were fantastic. Communication was strong, pricing was fair and most of all, they delivered on everything they promised, including coming within the budgeted price and finishing right on schedule (only 3 weeks!). John was very flexible about timing when delays mounted because I was waiting on specific windows. I appreciated that he also allowed me to order myself when I had something particular in mind, but for everything else, he chose high quality materials and got the job done. No fuss, no muss. Once the work began, their team showed up right as planned. Their work is detail-oriented and I enjoyed all my interactions with the crew - they were super friendly and always considerate. John was great about ensuring that everything met his quality standards - to the extent of ensuring that we had a doorstop to prevent the French door from hitting a light fixture. I'm about as picky as they come, but I would recommend Shed Mania with no caveats to anyone who is looking for some additional space. I'm thrilled with our shed and have been enjoying it every chance I get. read more

John and company were excellent to work with. First off, they are very friendly, honest, and professional. Every time I asked a question, an immediate response was received. He made me feel very comfortable doing business with him and was not pushy at all. On build day, they delivered all the materials to the front of my house. They also helped me break down my old shed and dispose of it. There was a team of 3 building the shed and they did so in about 3 weeks time working 5-6 days a week. The guys building the shed were very friendly and were very receptive with my critiques. The shed itself came out great and looks like it will last for quite some time. It is well built and definitely impresses my guests. I basically got most options from solar, AC, deck, pillars, shingles, and a larger unit with higher ceilings. This will eventually be my golf simulation shed. I couldn't be happier with the build. Thanks for the excellent work! read more

During the pandemic, my husband and I realized that we needed some additional office space - working from our living room and our bedroom was no longer sustainable. We reached out to Shed Mania. John was extremely responsive and helpful throughout the process, making the sign-up process seamless. Due to the high demand, there was a wait time of a few months. Luckily, our project was able to start earlier than anticipated. The construction crew worked during the week, keeping the noise level at a minimum throughout the construction phase. They cleaned up at the end of each day which we really much appreciated. At various phases of the project, Song, John's partner, came by to check in on the progress and give the team direction. Song handled the electrical work as well as the finishing touches. We could not be more thrilled with the end result. Song and John were really flexible with our last-minute updates and open to suggestions as well. Overall, we had a great experience with Shed Mania and will definitely recommend them to anyone looking to add backyard space. Thank you, John, Song, and team, for the amazing job!!!

We highly recommend Shed Mania. We hired many contractors in the past for other projects, this experience with Shed Mania went above our expectations. The consultation with John was pleasant. He was not pushy but he listened to our vision and offered recommendations. The crews showed up early 6 days a week and cleaned up after themselves. They made adjustments based on our inputs throughout the project. John & Song we're dialed in the whole time. They checked in with us regularly and made sure we were happy with the progress. They're not your typical shed builders, if you have a vision, they will definitely bring it to life. For example, the custom rail that Song and his crew built from scratch (see picture). We're very impressed and will definitely call John when we're ready add another shed. read more

I haven't logged into my yelp account in probably a decade, but I feel I have to write a review. I cannot say enough good things about John, Song, and the entire Shed Mania crew! John ensures you feel like you're their only client at all times (though they are very busy!), and is very patient with ensuring your scope of work is exactly what you want. We had several scope changes during the course of the build, and each time they listened to our concerns and ensured they were addressed. We were particular about wiring locations for speaker wire, ethernet, tv and they ensured everything was exactly as we wanted. John made a great suggestion about the siding trim to match our house and it looks great! We couldn't be happier with the overall end result and it's truly the focal point of our yard. John and Song are both very genuine people, and when the crew was onsite they even helped us build a small structure in our garage (out of scope), and extended our porta potty rental due to the immediate yard remodel right after. Highly recommend the Shed Mania crew!!! read more

I would give Shed Mania more than 5 stars if I could. When I was looking for someone to build a studio shed, I first contacted another company that considers themselves "The Bay Area Shed Leader". They were unresponsive and ultimately very rude and entitled. Thankfully I did a bit more research and found John and Song. And there is a new Bay Area Shed Leader: Shed Mania. Throughout the process, Johns communication was clear and responsive. I went back and forth with the size and style I wanted, and John was always patient and helpful. Song is a master. He managed the build of the shed incredibly well and the whole team did a fantastic job. Excellent build quality. John & Song confidently stand by their craftsmanship and have been very helpful with my questions and inquiries even after the job was done. I cant recommend them enough. If I ever need more work to be done, They will be the first ones I call. Customer for life. read more

I first spoke to John about adding an office shed to my backyard. He was very knowledgeable and gave me advice on the design. The materials arrived while I was out of the country and originally I was worried about not being present, but John assured me everything would be taken care of and when I returned from my trip the shed was almost complete. So far I'm really happy with the quality of work and communication has been very smooth. Highly recommend! read more

My journey started with the desire to build some extra space for an office. It ended with a killer entertaining space and office! John is the ideas guy, and Song is the guy who brings those ideas to life. They make a great team. The process from start to finish was simple. John was extremely responsive when issues or additional requests (which I had lots) came up. There was a brief snafu with build and placement of the ladder for the loft but between John and Song, it was quickly resolved and the end result I think was even better than what we had originally planned. As with any construction project, issues will come up, however, how those issues are dealt with and resolved will make the experience just an okay experience or a great experience. This to me was a great experience. If you're looking for some extra space outside your home, I would highly recommend you talk to John. He'll give you some great ideas. read more

Hey Yelp. I typically don't leave reviews, but I wanted to provide feedback they may help someone looking around for a backyard office/studio Contractor. I reached out to Shed Mania and got in contact with John. He is super responsive which is one of the number one things I appreciate when working with a Contractor. I got several bids but ultimately went with Shed Mania due to 3 main reasons: 1. Responsiveness 2. Cost/Availability 3. Loft options I did a lot of online research with companies that did studio kits like studio-shed, kitHAUS, and modern-shed. But by the time I priced it out with shipping, upgraded windows and french doors, finding local contractor to built it, the price shot up from advertised $20K cost to upwards of $40K-$55K. And those kits did not even include a loft option. After I decided against going with online services, I opted to research the local Bay area contractors. There are several companies that build backyard studios in the Bay area now especially after the Pandemic started early last year. I reached out to several of them as stated earlier. I am extremely happy I went with Shed Mania. Working with John and Song was a great experience as they took care of everything as a turn-key contractor. They finished my project in 2 weeks. I woke up Saturday morning that 1st week and was surprised to seem them out there. Extremely professional and hard working. My Project Specs: -10'x12' Studio - Set on Piers - French Doors - Laminate wood floors below and in loft - One 36"x36" Window - Five black transform windows - Loft with Wall rungs instead of latter - Six Electrical outlets below, and two up in the loft - Two exterior lights - 8' wide porch deck and awning - Six recessed can lights - Mini split HVAC - 12' Retaining wall behind the studio I have been using the studio as my office for a few weeks now. I wish I had pulled the trigger and had them build it for me sooner. read more

Highly recommend John and his team. They were excellent at communicating and addressing our questions, understanding our vision for our backyard office and executing on it quickly and beautifully. We're so pleased with how the office turned out - it's so comfortable and well built and we always get compliments from friends and family who visit. It's small enough to still leave plenty of room in our backyard for outdoor space, but big enough to comfortably fit our desk and chair, sofa/pull out bed and tv stand for storage.

I am so glad we found John at Shed Mania to build our backyard studio shed! At least for the next couple of years, this will be a sewing studio and study space for my daughter. She's still working on furnishing and decorating, but so far, she is so happy to have a nice, quiet, air-conditioned space of her own to be creative.

I wanted to give props to John and his team for my beautiful new shed! During COVID, it seemed like everyone wanted more space and so the shed business was booming and it was difficult to find someone who was booked months out. Since my shed was more for storage than a complete ADU, he was able to squeeze my project in that weekend and completed it within 3 days. He was reasonably priced, worked with my specifications (he even installed a few shelves in the shed) and did it quickly and efficiently with minimal direction. John was also highly communicative via email and text. He runs a tight ship and I appreciate his transparency and ability to let me know how things were going throughout the process. Highly recommend to anyone needing a storage shed or something more robust! read more

I am extremely happy with how my shed turned out. Song, John and the crew were terrific from day one.

John and his crew built me the perfect shed for my Reiki practice! They were very professional, friendly, honest, and straightforward. The best part of Shed Mania is that when they finished my shed it was move-in ready. They are a one-stop shop--they do it all! My shed was painted inside and out, all light fixtures were in place, flooring done, doors and windows in, heating/AC unit installed, and the awning and deck were complete. Plus they finished the job early and on budget. I didn't pay a penny more than was estimated. It was an absolutely delightful experience and I would recommend them to everyone I know.

Shed Mania recently constructed a 10'x12' shed for us. We are using it as a spare room and just recently had an out-of-town guest stay with us in it. She reported it as very comfortable and cozy. John was accommodating during the design process and allowed us to have a slightly custom layout with an elevated loft in the back of the shed. There were some minor delays due to supply constraints but that is just the overall state of building materials these days. The project was still completed within a reasonable time frame and the crew was industrious, efficient, and clean. read more

I searched many shed options in the East Bay, and Shed Mania was the clear winner in terms of quality. Other options were either too low quality (think tool shed quality) or they were pre-fabbed and offered no customization.

They worked quickly and diligently, and it was cool to see my office shed built from scratch in a few weeks.
