Mika and Brian Kleinschmidt are the Olympic trainers of the HGTV family. On 100 Day Dream Home, the fleet-footed couple has perfected the art of designing and executing their clients’ personal visions while sticking to a schedule that would make fellow professionals blanch. She’s a realtor who envisions the finish line. He’s a developer with the skills to coach each home through its transformation — and the spaces they create together are unbeatable. This highlight reel of their very best is sure to put a spring in your step.

Contrast plays a starring role in this clever kitchen from 100 Day Dream Home’s second season, where the Kleinschmidts paired a tall, sleek bank of dark-stained cabinets with tone-on-tone contemporary hex tiles to create a dimensional backsplash. A pale, waterfall-edge island runs parallel to those cabinets, facilitating foot traffic in and around this gracious space. Variegated tones on the wood flooring contribute a note of organic warmth. Less-is-more pendants, in turn, spotlight the island without adding visual clutter.

This contemporary St. Petersburg, Florida, kitchen from Season 3 of 100 Day Dream Home combines sleek, minimalistic silhouettes and showstopping, natural grandeur. Get a load of the gorgeous waterfall edge on that extra-long island and the crisp contrast between the white upper cabinets above the range and the black, floor-to-ceiling installations framing them. The dramatically veined panda marble slabs they used for that island and backsplash add movement to the room and render accessories superfluous. Why embellish perfection?

The Kleinschmidts were crowned the winners of Rock the Block’s second season. Given the magnificence of the kitchen they designed as the heart of their Atlanta-area Southern Craftsman, it’s easy to see why. Crisp, custom cabinets offset the brilliant blue island, provide all the storage a lively family could need and conceal the doorway to a pantry that offers even more functionality. That stone-topped island boasts a pair of dishwashers that facilitate both weekday cleanup and hosting larger get-togethers, while vinyl plank flooring delivers style that can stand up to heavy use.
