**★★★★★ — Marlene Schumm, Dec. 2018**

> Jill was very attentive and determined to create what we had in mind. We had a lot of personal disruptions and she oversaw things while we dealt with other things. Always provided information before things were done. She exhibited extra effort in the details.   When something was not done in a manner fitting to her it was redone.

**★★★★★ — Leah, Aug. 2017**

> Jill is fantastic! She has a wonderful knack for learning about her clients' style preferences and then designing a masterpiece that reflects her clients' tastes and her expertise and impeccable taste and design sense. She genuinely enjoys getting to know her clients. She is easy to work with, highly responsive and communicative, patient and flexible, and very knowledgeable. She has great relationships with vendors/suppliers and good knowledge of a variety of fixture and appliance product lines. We would love to work with Jill again. (We worked with her on a kitchen remodel in 2015 and a master bath remodel in 2017.

**★★★★★ — Linda Finerty, Dec. 2016**

> Jill was wonderful to work with.  She had great ideas and was very patient with me.  We went to granite showrooms multiple times!  Our kitchen is exactly what we wanted, even better!
> I highly recommend Jill!

**★★★★★ — kvuitel, May 2016**

> Working with Jill was wonderful!  She designed a master suite addition for me that included expanding a guest bedroom into a 'mini suite' and creating a deck to connect the two spaces.  She was a pleasure to work with as we went through all phases of the project.  She understood what I wanted and helped guide me there from both a design and cost perspective.

**★★★★★ — pcsimp, Oct. 2015**

> Jill was the designer for my condo remodel. She worked seamlessly with the production team, had thoughtful and insightful advice about space planning and selections, and was extremely professional. I'd recommend her work for any size project.

**★★★★★ — pickle53, Aug. 2015**

> We have used Mosby Building Arts for 2 remodels, the first was a pet friendly laundry room and new deck and rail.  The second was a major kitchen remodel and  sun room.  Both times Jill was our Project Planner and Designer and we couldn't have been happier with her work. She is a very talented designer with great people skills.   Jill was great to work with, listening to our wants, needs and concerns and incorporating them into our plans.   Even when we weren't sure what we wanted Jill was quick to learn "who we were" and make suggestions accordingly.   She walked me through all the choices that had to be made recognizing that I don't really like making decisions.   We liked that Jill was flexible and honest in her assessment of the design, making changes as needed.  She communicated promptly throughout the remodels by phone, email, and visits.   We highly recommend Jill and will be using her for all our future remodels with Mosby.

**★★★★★ — Kristi Van Luven, Oct. 2014**

> Jill was great to work with!  She listened to what we wanted & guided us through ALL of the decisions so that our vision would be realized!  Our kitchen is absolutely perfect for our family. She was available for everything including the tiniest of details!  Hands down, this remodeling project was a success!

## Selected projects

- [St. Charles, MO Pet-Friendly Laundry Room](https://www.houzz.com/hznb/projects/st-charles-mo-pet-friendly-laundry-room-pj-vj~330943)
  - Location: Saint Charles, MO
  - Photos: 10
  - Description: A laundry room remodel designed to accommodate the pets just as much as the humans. It was time to step up the function of the utility room between the garage and kitchen in this St. Charles, MO home. The owners now have a highly organized laundry room that multi-tasks as a home office, pantry and pet-feeding area. One customized design highlight is the cat's private bathroom, so Bubba can get in and out while the dogs stay out.
- [Frontenac, MO Library & Billiards Room](https://www.houzz.com/hznb/projects/frontenac-mo-library-and-billiards-room-pj-vj~589939)
  - Location: Frontenac, MO
  - Photos: 10
  - Description: With the children grown, it was time to personalize the basement for the parents. A small game room and an unfinished area were combined to become an Old World, African mahogany wood paneled library with a stone fireplace and built-in desk. A 161-gallon saltwater fish tank is the dividing wall between the library and the updated billiard room with a handsome two-tone wood floor.
- [Ladue, MO Home Office Suite](https://www.houzz.com/hznb/projects/ladue-mo-home-office-suite-pj-vj~2250826)
  - Location: St. Louis, MO
  - Photos: 9
  - Description: Now that the man of the house is retired and spends more time in his Ladue, MO home office, he noticed the need for an updated bathroom, a better-organized closet, and he really wanted to open the shutters and let the light in, but he needed to protect the artwork from sun damage. It was time to refresh. After relocating the entry between the office and closet to gain more space in the bathroom, the original wood floors were uncovered and refinished. A seagrass cloth wallpaper (also used in the…

  - Location: Clayton, MO
  - Photos: 12
  - Description: A home built in 1914 had an oddly divided kitchen with a hard to reach butler's pantry. By removing walls and creating new entry points, a modern kitchen with an era-appropriate look enlivens a family with natural light and plenty of work and gathering places. The kitchen includes a laundry room, dining area, chalkboard column and a swivel-mount TV above the refrigerator.

  - Description: The new owner of a 12 year-old condo in Kirkwood, MO needed to make some changes. Leveling the floors, installing more efficient windows and removing the hot tub from the master bathroom were the starting point. While working with the Mosby team on these items, she decided to make further changes to tailor the home to her tastes and lifestyle. The open-plan main living area has a breezy, contemporary feel because decorative columns were removed, the entrance to the home office was reconfigured (…
- [University City, MO Master Suite Room Addition](https://www.houzz.com/hznb/projects/university-city-mo-master-suite-room-addition-pj-vj~2251938)
  - Location: University City, MO
  - Photos: 11
  - Description: A University City, MO ranch home has to room additions built on the rear of the home to create expanded bedrooms connected by a new deck. The original master bedroom is converted into an expanded guest suite by adding 4 feet to the rear and updating the bathroom. By reconfiguring the hallway, you now walk down to a light-filled 18x18 foot addition that is the new master bedroom. What was a small guest bedroom becomes the new master bathroom.

## Community Q&A

**Q: Size of cat cabinet** *(in Photo Questions)*

Clever! What size is the cabinet?

A: Glad I could help and good luck!

**Q: What type of countertops are these? Thanks!** *(in Photo Questions)*

A: The countertops are Honed Absolute Black Granite.  Thanks for asking!

**Q: need help choosing bathroom counters!!** *(in Design Dilemma)*

I am remodelling & am trying to decide whether to use marble or granite on the bath countertops. Does anyone know much about the difference? Thanks so much!

A: Perhaps look for a remnant.

**Q: decorative painting** *(in Design Dilemma)*

Just wondering what others think about this kind of decorative painting / "faux finish"? I'm considering having one wall in my LR done like this. not so much concerned with coordinating the specific colour as I am the technique in general. I like it but worried it might be considered a dated look. Thoughts?

A: I love it. It looks like beautiful Venetian plaster.
