Mosby Tour: A University City Master Suite Addition

by | Bathrooms, Design & Remodeling, Mosby Tour, Room Additions


A University City, MO home built in 1957 has responded brilliantly to constant transformation. Both inside and out, our homeowner has remodeled most every square inch of her house, and we’ve been there to help. After each project, we think there’s nothing left to do to such a beautiful home. Ah, but there was…

The only way to get the perfect master suite she longed for was to add it on to the back of her home. And could that addition also create a way to have a deck off her bedroom? So Mosby Building Arts designer Jill Worobec conjured some magic to make it happen. See the before and after floor plans above.


Here is the before and after of the exterior of her home. The two room additions are of white vinyl siding abutting the painted grey brick. Both bedrooms now have glass doors that lead out to the new wood deck that joins the two spaces.


Above we see Mosby Consultant Rich Oris in the home’s original hallway. Behind him is the door to what was then her master bedroom, and which has now become an enlarged guest suite. The door across from Rich remains a spare bedroom in the original location. But the door at the end of the hall – and the end of the hall itself – was completely rejiggered.


This is the new hall configuration. You get a peek at the new master suite at the end of the hall, but first, let’s take a left into the new guest suite.


This used to be the tiny master bedroom. We added 4 feet to the rear wall, and doors leading out to the new deck.  A coffered ceiling, new flooring and paint add personality. The drum light chandelier is from George Kovacs.


The original full bathroom (the door on the right, above) remains in place, but vastly improved. We updated all the finishes and fixtures, and installed a walk-in shower where a tub and shower used to be.  When you exit this cheery and spacious guest suite, hang a left to make your way to the new master suite.


Here is the generous new master bedroom, which is 18 x 18 feet of brand new construction.

PAINT  Sherwin-Williams Silverplate
FLOORING  Red Oak plank
FRENCH DOORS Provia Legacy in a Snow Mist White finish


You can step out onto the deck, or walk through the sliding barn door to the new bathroom.


This bathroom now occupies the space that used to be a third bedroom. It was tiny for a bedroom, but it’s just right for a bathroom with twin sinks, a curbless walk-in shower and a neatly organized closet. Another good feature is the solar tube in the ceiling, which provides natural light all day long so the room is never dark.

There are two sinks separated by a sit-down makeup counter with a fun feature – an 8” mirror from Simple Human with touchless sensor light. The homeowner sits down in front of it, and on it comes!

WALL TILE  Daltile Evening Veil
COUNTER TOP  Delicattus granite
SINKS  American Standard Studio Undermount in White
FAUCETS  Brizo Siderna single-handle in Chrome
VANITIES  Showplace cabinets, Santa Fe style in cherry with a Brandy finish


One of the favorite views of both the homeowner and our remodeling team is this one, above. When you stand in the walk-in closet and look out, you get a true sense of how expansive and gorgeous the master suite addition really is.
