They designed the plans for a beautiful family room and bedroom addition, expanded our laundry room, and even incorporated a stylish coffee bar—all with thoughtful detail and creativity. > > From start to finish, the owner and her team were consummate professionals: responsive, attentive, and truly committed to bringing our vision to life. The entire process was smooth, and their expertise gave us complete confidence every step of the way. > > I was so impressed with their work that I immediately recommended them to friends, who have also had equally positive experiences. I wouldn’t hesitate to work with them again on future projects. Highly recommended! **★★★★★ — tarabv, May 2024** > We came to Denise with a bare bones idea for our dream house and she turned it into reality! We had no previous experience with home building or design, but when we had the opportunity to build a new house from the ground up, we chose Xag Designs and we are so glad we did! Denise is talented, knowledgable, and has vision. Denise and her team worked patiently with us to design a home that fit our space and our lifestyle. Denise’s commitment to, and passion for, our project has reassured us when we faced challenges. Denise can get things done - we have just broken ground on our build and will be back with photos upon completion! **★★★★★ — kklevine, Oct. 2021** > We used XAG Designs for our full home remodel, addition, and casita. Denise is terrific at working within a designated time frame and getting questions answered quickly. While the project was planned, started, and executed during COVID, Denise went to the building department whenever an issue arose and worked with phone calls and emails when the city offices were closed. Our project was extremely tricky being in a fire zone and landslide area, and Denise really worked with us and the city to get our house as safe as possible - the city was happy we followed all their specific guidelines, and we felt comfortable that by following the engineering, siding and landscape rules we would be as protected as we possibly could. Denise is also a great collaborator. I wanted to help with the design decisions and we worked together to create floor plan layouts, etc. For me, this was especially valuable because she listened and provided ideas we could work from. I would definitely work with Denise again!! **★★★★★ — Shamim Wu, Oct. 2021** > XAG Designs was a lifesaver for us, and we are so grateful for Denise's work. She was instrumental in bringing our vision to life. She always makes herself available, and went above and beyond what our project required of her. **★★★★★ — letheridge, June 2021** > XAG Design's Denise Xagorarakis was the lead architect on our home remodel/2nd story addition. This project added over 800 SF to our home and required structural support and retrofitting (see the photo below of the steel beam being placed into the new 2nd story framing). We also remodeled our kitchen to add a window that ran the full length of the front wall. This required creative working for electrical, plumbing, venting, etc. Denise handled all of this with expertise. We found Denise to be very knowledgeable, professional and detailed. She had great ideas, worked within the rules of our city and HOA (no small task) and was a consummate problem solver. Our HOA, known to be difficult on architectural projects, seemed quite impressed by her presentation of our plans. We sailed through their approval processes, thanks to Denise, and we had no trouble with the city’s permitting department. Denise also made herself available to consult on questions and stepped in on any issues we had. I would gladly use her services again and would recommend her without reservation. **★★★★★ — Frank Heyming, Dec. 2020** > Our 100 year old barn burnt down in June 2019. XAG Designs was recommended to us by another architect. Denise listened to us and understood our desire to make the new structure look just like the old one. She assisted every step of the way. We can't say enough good things about XAG Designs. We know our new barn will last another 100 years! ## Selected projects - [SANTIAGO II](https://www.houzz.com/hznb/projects/santiago-ii-pj-vj~7286847) - Location: Newport Beach, CA - Photos: 14 - Description: Iconic 1957 Mid-century Modern home nestled in Newport Beach, California, has become synonymous with the majestic Brazilian peppertree adorning its front yard, a beloved landmark cherished by locals.

Used this photo as inspiration. Got the same wallpaper. Similar gray vanity, brushed bronze mirror, black water fixtures, light fixture mix of black and bronze. Original plan was to wallpaper just the wall behind the vanity and toilet A: For a small space, definitely all the walls in the bathroom. **Q: marble in kitchen but quartz in rest of home?** *(in Design Dilemma)* I have fallen hard for some honed calacatta caldia slabs. However, they are quite expensive at $9500 per slab. My budget allows for two, which is enough for the kitchen. I was thinking I could do a basic white quartz in the pantry, master bathroom and laundry. But my designer says I need to carry marble throughout the house. Am I building a Frankenstein home if I put marble in the kitchen and quartz everywhere else? A: Kitchens and Baths 100% do not need to coordinate counter material. However, the kitchen and pantry would depend on how the spaces relate to each other. Do what you LOVE! The kitchen is the perfect place to splurge. --- *Source: Houzz professional profile.
