Leslie Davis and Lyndsay Lamb's 'Rock the Block' House Reveal

Twin sisters Leslie Davis and Lyndsay Lamb from Unsellable Houses were ready to kick off Season 3 of Rock the Block with a competitive spirit. As real estate agents, the pair knew exactly what would add value to their house.

Starting with a large but boring kitchen, the duo immediately pinpointed this space's purpose: entertaining — which meant a huge dining table and a sizable island was in order. The sisters also planned to remove the corner pantry to create extra cabinet space.

The sisters didn’t want to hold back on this blank canvas kitchen. With an estimated budget of $55,000, they planned to add a service bar and accordion glass doors that open to the outdoor patio to focus on making the kitchen perfect for hosting.

Lyndsay and Leslie's final kitchen boasts dark blue cabinets, quartz countertops and a large vintage-style stove. They combined Lyndsay’s taste for wood and color with Leslie’s simple and clean designs to create a classic and eclectic kitchen with earthy tones.

Since this season is located in South Carolina, Lyndsay and Leslie wanted to add some southern charm a la sweet tea. With hosting in mind, they installed a service bar complete with a sweet tea station.

New Kids on the Block singer and Farmhouse Fixer star Jonathan Knight arrived alongside his brother and former bandmate Jordan Knight to judge the twins' kitchen. The brothers were wowed by the accordion style doors, unique stove and sweet tea station. Jonathan and Jordan critiqued the cabinets, reasoning their dark blue color might not fit everyone’s taste.

The large, open-concept space begged the twins' eclectic designs. They planned to extend the countertops throughout the dining area for even more work space.

Dark hardwood floors and a glistening light fixture illuminate a family-style dining table where lots of people can gather. The twins grounded the entire space with plants and earthy tones for an inviting environment.

During week two, Lyndsay and Leslie stepped up to the plate even more determined (especially after Jonathan called them basic). They decided to expand their eclectic theme into the living room and allocated $17,000 of their $167,000 remaining budget on the space.

The twins added several beams on the ceiling to draw the eye up and give the room a cozy feel. They carried the hardwood floors from the kitchen into the living room, then dressed the space with unique light fixtures and layered rugs.

Hoping for a twin win this week, Lyndsay and Leslie pulled out all the stops for this vintage 1813 mantel. The pair found the historic piece at an estate sale and put in some extra elbow grease to repaint the mantel and bring it up to fire code.

With hosting in mind, Lyndsay and Leslie installed a wet bar (complete with built-in cabinets!) to the left of the fireplace. In total, they spent $7,170 of their budget on the very-grand fireplace area.

The twins knew they had to make a great first impression in the entryway: A focal wall of maps, sconces and a dramatic light fixture accomplished just that.

Instead of breaking the bank on wallpaper, Lyndsay and Leslie used vintage maps as the subject of their focal wall. According to Charleston history and folklore, the maps are meant to “stop potential intruders” in the entryway by distracting them with something to read.

Then Jasmine Roth, host of Hidden Potential and Help! I Wrecked My House, showed up to judge the constestants' living rooms and entryways. Jasmine loved the vintage mantel, but said she would have painted it a different color. She thought the wet bar “checked the box” on the appraisal value and appreciated the use of the beams on the ceiling.

Week three was all about the main bedroom and bathroom, and Lyndsay and Leslie set aside a hefty budget of $35,000 of their remaining $150,000 for the space. Their goal for the bedroom and ensuite was to create high-end amenities that add value to the house.

A four-poster king bed, a grand floor-to-ceiling mirror and warm tones accented throughout the space created the luxury main bedroom buyers look for.

The team also added French doors for private access out into the patio space. All of the windows brightened up the room and added value to the property.

By expanding the closet out into the hall and stealing some real estate from the outdoor patio, Lyndsay and Leslie were able to add 50 square feet into their closet of dreams. They dropped $2,775 on luxury built-ins and even found room for a private washer and dryer in the closet.

Contestants were faced with their first design challenge: to incorporate a Charleston-inspired material into their spaces. There were four different materials (one for each team). Egypt Sherrod and Mike Jackson, winners of week two, chose first. Lyndsay and Leslie got second pick and went with reclaimed hardwood pine, which they installed into the walls of their closet.

In the ensuite, the duo decided to remove the extra closet to make room for a double shower and bath, creating one of the largest showers the show has seen. They knew the bathroom wouldn’t be complete without a double vanity, finished with intricate wallpaper and brass sconces.

Lyndsay and Leslie had a hiccup when about a third of their $10,895, top-notch tile arrived cracked. But they saved it by switching up the design and installing only a single stripe of the dark green tile.

Rock the Block veteran and host of Windy City Rehab, Alison Victoria, and real estate broker and host of Fix My Flip, Page Turner, brought their expertise to judge the block on week three. The judges loved Lyndsay and Leslie’s extra closet space — especially the washer and dryer, which added lots of appraisal value. Topping it off with the large shower and high-end tile in the ensuite, Alison and Page crowned the twins the winner of the main bedroom and bathroom.

In week 4, the designers took on the F.R.O.G. (finished room over garage) space and the second floor loft. Lyndsay and Leslie had already spent $115,000 of their budget, but after their win in week 3, they earned an extra $3,000 to put into this blank yet versatile room.

The twins decided the best way to add value to their house was by transforming the F.R.O.G. into a separate, rentable apartment. They completed the space with a kitchenette, full bathroom and living space with a daybed.

Lyndsay and Leslie allocated about $18,000 of their budget to the F.R.O.G., spending some of their extra prize money on a full-sized stove and a tumble brick backsplash in the kitchenette. They left the space above the floating shelves open to let in more natural light through the wall.

Looking to add appraisal value, the duo designed a fully functional bathroom in the F.R.O.G. They kept the colors light and fresh to contrast with the matte black hardware.

The first thing homeowners see when they come up the stairs to the second floor was this blank loft space. Lyndsay and Leslie planned to turn the loft into a study space without breaking the bank.

Together, the two custom wooden desks and the pegboard cost $865 of Lyndsay and Leslie’s budget. They gave the room a playful feel with spotted wallpaper and pops of yellow and blue.

To create an interactive wall that can be versatile for children of all ages, the team built a floor-to-ceiling wooden pegboard. The coolest part? Inserting wooden dowels into any of the holes makes for the perfect spot to display artwork, crafts, school supplies and more.

This week, power duo Jeremiah Brent and Nate Berkus, Season 2 contestants and co-hosts of The Nate and Jeremiah Home Project, judged the F.R.O.G. and loft spaces. They loved Lyndsay and Leslie’s layout in the loft, and Nate said his jaw dropped when he entered the loft. However, Nate worried that the pegboard feature might be too specific for most homebuyers.

In week five, the teams focused on the exteriors of their houses, as well as landscaping in the front and back yards. As real estate agents, Lyndsay and Leslie know the importance of curb appeal, so they set aside $75,000 of their remaining $90,000 budget for this section of the renovation.

The twins decided to dress the garage in dark tumble brick and side the rest of the house with blue-green painted shake shingles and gray-blue painted board and batten.

To turn this mudpit into a masterpiece, Lyndsay and Leslie focused on amenities and landscaping.

In addition to fresh sod, mulch and lots of greenery, the duo constructed a private stone patio off of the owner’s suite and built a fence for privacy.

For the ultimate getaway, Lyndsay and Leslie added a pergola with outdoor string lights over the owner’s suite patio to make it feel sectioned off from the rest of the backyard. They completed the setup with two wood dining chairs.

As a nod to the Charleston tradition of hosting oyster roasts, the twins dropped $14,000 to install an oyster oven on the back patio. The igloo-shaped oven is also great for making homemade pizzas. They also added an outdoor grill and kitchen on the opposite side of the patio.

Ty threw a new challenge at the teams this week: create a dog-friendly feature in the yard using an extra $1,000. Lyndsay and Leslie made a dual-purpose shower station for rinsing off muddy boots or giving dog baths.

Mother-daughter duo Mina Starsiak Hawk and Karen E. Laine of HGTV’s Good Bones judged week five of the competition. They loved Lynsday and Leslie’s outdoor kitchen and oyster oven. Their only critique was they would have spruced up the dog washing station with brass fixtures.

Week six marked the Season 3 finale of Rock the Block, and the teams were ready to put their all into the last final on their houses.

Lyndsay and Leslie geared up to take on the third floor bonus room. They had four days to complete the challenge and get their house ready for the final walkthroughs.

With only $8,000 remaining in their budget, the twins decided to spend $7,750 on a media room with an additional full bathroom. They hoped to add to the appraisal value of the house while incorporating a fun entertainment element.

The bonus room was transformed into a theater with dark grey-blue walls, a $200 movie projector and a comfortable sectional. The media room also doubles as a spare bedroom for guests.

Lyndsay and Leslie spent $7,000 renovating one of the bonus room’s closets into a full bathroom with a shower.

In true finale fashion, HGTV host and Property Brother Drew Scott and 100 Day Dream Home duo (and Season 2 winners!) Brian and Mika Kleinschmidt stepped onto the block to judge the houses in their entirety. Lynsday and Leslie proudly presented their historic-eclectic style home.

In the living room, Drew, Mika and Brian appreciated the custom built-ins on either side of the fireplace and were drawn the character and color in the twins' designs.

The risk Lyndsay and Leslie took in week one to paint the kitchen cabinets a bold color paid off with these judges. Drew said he loved their choice of the dark blue cabinets. The judges also loved the accordion door they installed off the kitchen to open up the outdoor space.

Lyndsy and Leslie got bonus points for taking all of Charletson’s rich history into consideration while renovation. Drew, Brian and Mika thought the oyster oven on the back patio was a smart investment.

Before the Season 3 Rock the Block champions were announced, the judges complimented Lyndsay and Leslie, saying they “captured that Charleston charm the absolute best” in their home.
