She helped me configure my new art studio and she has really helped me get the Fun back into Functional! Without her expertise I would have had no idea how to design all my fixtures and properly store supplies and necessary but not always attractive art "stuff". > > This beautuful creative space is my new business home, combining workspace and gallery so I can proudly invite clients to visit. Ursula's spatial prowess and exquisite taste are phenomenal and I give her super duper top marks! **★★★★★ — joenaworski, Feb. 2014** > Ursula at Square One came into my life over a decade ago and I am so glad she did. She is the ultimate professional and a wonderful spirit. I have moved several times over the years and her wisdom and creativity always made the houses into homes. Her ability to listen to what you want and then translate that into something totally unexpected and terrific is her greatest attribute. > > Work done of the years: > > Complete remodel of my Kitchen, Master Bathroom, and Dinning room. ( I don't know what I would have done if she was not the project manager on these. She was phenomenal when dealing with all the contractors and suppliers. She kept the project on time and within the budget. How many people can say that about a major renovation?) > > Interior design on 4 houses including all furnishings, window coverings and rugs (her taste is impeccable and she really set my homes apart from any I have ever seen). > > Art Acquisition (This can be a tough area to match up your taste with you hers but she does it beautifully. Again, she always seems to find something special that you never knew that you just had to have). > > I promise you that should you choose to do business with the awesome lady you will be in for a great experience!! I know that I will turn to Ursula for many years to come. **★★★★★ — mbouchet, Jan. 2014** > I've worked with Ursula a number of times and can't imagine starting any project without consulting her. Working with her has saved me time, money and the agony of making horrible design decisions that I'd be forced to live with forever. > We had a tight budget for our kitchen remodel and she came up with a design that was not only within the budget, but looked much more expensive. > As a Realtor, I've seen enough design work to know Ursula is one of the best. If you think hiring a designer is a waste of money, please think again. Remodeling is expensive and a good designer will save you money and huge headaches. > I would recommend Square One Interiors without hesitation. **★★★★★ — Khrome Studios, Jan. 2013** > I have known Ursula for many years, as an associate, designer, and client. > Her architectural education is obvious in her kitchen and home interior and exterior designs. She is a perfectionist in all that she does, her attention to detail is something that I find lacking in many designers. Her work stands the test of time. The kitchen she helped me with in 1996, put our home into a bidding war in 2004. (not the best time to buy). Her interiors are perfection. ## Selected projects - [wignall](https://www.houzz.com/hznb/projects/wignall-pj-vj~6329581) - Location: Not specified - Photos: 2 - [piper](https://www.houzz.com/hznb/projects/piper-pj-vj~6329583) - Location: Not specified - Photos: 4 - [baird](https://www.houzz.com/hznb/projects/baird-pj-vj~6329584) - Location: Not specified - Photos: 3 - [givens](https://www.houzz.com/hznb/projects/givens-pj-vj~13921) - Location: Not specified - Photos: 3 - Description: Remodeling three bathrooms and a powder room was our task after furnishing the majority of this San Francisco home. In the master bathroom we worked around already existing marble tile on the floor and walls - challenging at best. We designed a new Asian inspired vanity to fit the footprint of the old vanity. New lighting was installed as well as new mirrors and a shoji style wall mirror. The concrete counter and splash features two integrated oval sinks and wall mounted faucets. - [chang](https://www.houzz.com/hznb/projects/chang-pj-vj~13916) - Location: Not specified - Photos: 7 - Description: This condo on the 17th floor on top of Russian Hill had a spectacular 290 degree view of San Francisco. Since the interior was rather dated we opted for an extensive remodel and new furnishings through out. We relocated the kitchen into a former guest room and now one can enjoy the SF view from the kitchen sink. The formal dining area and living room were expanded since the old galley kitchen is now gone. Both bathrooms got a complete over haul. By "stealing" a closet we were able to create a wa… - [field](https://www.houzz.com/hznb/projects/field-pj-vj~14202) - Location: Not specified - Photos: 2 - Description: Nob Hill condo getting prepared for sale. We edited the existing antique furnishings using them in various areas through out this top floor condo. In the bedroom we added the romantic four poster bed and bedding. The living room was upgraded with new drapes, seat covers and paint. - [worth](https://www.houzz.com/hznb/projects/worth-pj-vj~14197) - Location: Not specified - Photos: 3 - Description: This young couples upcoming wedding made this a very fast paced project for us. We furnished this San Francisco condo through out in a comfortable contemporary style. The dining room features an elegant Italian chandelier over the round dining table. Barbara Barry lounge chairs and custom bedding make for a romantic bedroom. - [scripps](https://www.houzz.com/hznb/projects/scripps-pj-vj~14195) - Location: Not specified - Photos: 4 - Description: Marina District condo with an eclectic flair. We used a whimsical mix of furnishings and accessories to create this home. A comfortable corner in an alcove is a favorite reading nook for this client. The bedroom and den have a feminine touch. - [ireland ca](https://www.houzz.com/hznb/projects/ireland-ca-pj-vj~14192) - Location: Not specified - Photos: 10 - Description: While my client spent 4 months in Honolulu we remodeled and furnished most of their extensive home in Atherton. Two new bath rooms, a master bedroom, guest bedroom, studio and a large walk-in closet were build from the ground up. We designed and selected all materials, lighting and furnishings through out the new addition. The fireplace in the living room was upgraded with new tile and furnished newly. The powder room also got new lighting and a vessel sink. - [ireland hi](https://www.houzz.com/hznb/projects/ireland-hi-pj-vj~14191) - Location: Not specified - Photos: 5 - Description: My client brought this Hawaii vacation condo in order to have a fun place to be for four months while we renovated their large home in Atherton. I was called in to spruce up the place that was a bit run down and dated. A fresh carpet, paint and a few new furniture pieces turned this condo into a stylish home for this professional couple. Of course the outdoor seating on the ocean view deck steals the show. - [huibonhua](https://www.houzz.com/hznb/projects/huibonhua-pj-vj~14190) - Location: Not specified - Photos: 1 - Description: Sometimes very little can have a big effect. We upgrades this kitchen with a colorful splash, added some under cabinet lighting and a few tucks here and there. Voila ... a completely new feel at very little cost. - [huen](https://www.houzz.com/hznb/projects/huen-pj-vj~14188) - Location: Not specified - Photos: 2 - Description: This young couple bought a condo in the Marina district of San Francisco. We furnished it through out. For the dining room I designed a whimsical drapery treatment with three scrim panels that shield the view into a light shaft. Modern art by Takeshi Nagayoshi creates a focal point on the wall. - [hansen](https://www.houzz.com/hznb/projects/hansen-pj-vj~14187) - Location: Not specified - Photos: 4 - Description: Master bath and guest bath remodel in Pacific Heights. While we kept the master bath rather traditional with subway tile and a mosaic woven band the guest bath was done in a very interesting tile from Ann Sacks. With slightly bowed edges the contrasting grout creates a star pattern. A dark wood sink stand makes for a transitional feel in this bath. - [gunn sf](https://www.houzz.com/hznb/projects/gunn-sf-pj-vj~14186) - Location: Not specified - Photos: 10 - Description: Another loyal repeat client. We started out with their home in the Castro District where we remodeled the kitchen and furnished the home throughout. We eliminated a very dated looking wet bar and replaced it with a modern art display and floating cabinet. For my second project with them we edited and re-used the best of their existing furnishings and added new pieces to fit the new space. My third project involved selecting all interior finishes, build-in cabinetry, floors, railings, lighting et… - [daugherty](https://www.houzz.com/hznb/projects/daugherty-pj-vj~14185) - Location: Not specified - Photos: 6 - [cooper](https://www.houzz.com/hznb/projects/cooper-pj-vj~14184) - Location: Not specified - Photos: 8 - Description: I love my clients that have a strong sense of color and "guts". This world traveled couple bought this North Beach condo to accommodate their bi-coastal lifestyle. I furnished the condo with comfort and relaxation in mind. I designed the accent wall in the dining area with a faux-finish and white lacquer and wood cabinets. Two art pieces are by local artist Jonah Burlingame. The bedroom was wall papered with a turquoise lightly sparkling wall paper on one wall. Upside down shade shield the view… - [shamiryan](https://www.houzz.com/hznb/projects/shamiryan-pj-vj~14183) - Location: Not specified - Photos: 9 - Description: This San Rafael home needed a new updated look. The family room / kitchen with breakfast area was too dark and needed a spark of color desperately. We took a rather "green" approach (to my clients surprise) by suggesting to paint the kitchen cabinets, media cabinet and book shelf units rather that replacing them. I think the result speaks for itself. The fireplace was updated with a new facing of textured strip tile. The living room was wallpapered with bark paper to give it interest and a warm… - [spencer](https://www.houzz.com/hznb/projects/spencer-pj-vj~14180) - Location: Not specified - Photos: 10 - Description: This three story residence on Twin Peaks needed a full fledged remodel. Extensive space planing revealed that we could create a large master suite with a newly added master bathroom with freestanding tub a large open shower and a toilet room separated by frosted glass. The entire project was very focused on using green materials. Most apparent in the kitchen with it's FSC wood cabinets and recycled glass counters. The stairway got a new cable railing system that updated the home greatly. Guest b… - [esmurdoc](https://www.houzz.com/hznb/projects/esmurdoc-pj-vj~14176) - Location: Not specified - Photos: 3 - Description: Full Redwood City town house remodel. A maple kitchen with glass mosaic splash was created. Two bath rooms got a major face lift. - [wilson sm condo](https://www.houzz.com/hznb/projects/wilson-sm-condo-pj-vj~14175) - Location: Not specified - Photos: 7 - Description: Project number five with my most loyal client and now friend. Ocean side condo in Santa Monica. We edited some of the furnishings the client already had and added just what was needed. Two bold flower patterned chairs brought a focus to the living room.

Thank you A: Wish I could help you, but this lamp used to be from crate and barrel and I have not seen it in their catalog for years. **Q: What's the tile? Hard to see close up.... but I think I love it** *(in Photo Questions)* A: This is a simple flat 12 x 12 gray tile from Daltile and a mosaic strip as an accent. **Q: headboard...where is it from?** *(in Photo Questions)* A: This is not just a headboard, but a complete bed that used to be in the potterybarn catalog. Doubt that it is still there though. **Q: What material and size of the kitchen tile?** *(in Photo Questions)* A: They are ceramic tiles. Since I did this project quite a while ago I do not remember the manufacturer and I think they are random sizes 6 x 24 and 6 x 30 long. --- *Source: Houzz professional profile.
