Kim Kardashian, Kendall Jenner, and Kris Jenner surprised their family friend with an HGTV backyard makeover

• Kim Kardashian West, Kendall Jenner, and Kris Jenner were on the season premiere of "Celebrity IOU."
• The trio gave Kris Jenner's longtime friend Lisa Stanley a yard makeover with the Property Brothers.
• The new space had an outdoor kitchen, outdoor fireplace, and large pool.

Season two of HGTV's "Celebrity IOU," starring Drew and Jonathan Scott, premiered on Monday with three very special guest stars - Kim Kardashian West, Kendall Jenner, and Kris Jenner.

The show, which premiered in 2020, allows celebrities to give back to their loved ones by teaming up with the "Property Brothers" hosts to create dream HGTV home renovations.

Celebrities like Brad Pitt, Jeremy Renner, and Zooey Deschanel guest-starred in season one, and the Kardashian-Jenner family continued the trend of the star-studded appearances in the season two premiere on Monday.

Kardashian West, Kendall, and Kris worked with the Scotts to give Kris' longtime friend Lisa Stanley the backyard of her dreams.

Kris Jenner turned her longtime friend's yard into an oasis

Kris and Stanley have been friends for 42 years, as they shared on the show.

"We're best friends," Stanley said of their friendship. "I'll be there for her forever."

Stanley acted as an aunt to the Kardashian-Jenner kids throughout their lives, so she's close with the entire family.

"I grew up idolizing her," Kendall also said of Stanley. "Lisa's just the best. She's the kindest person, the most genuine person I know."

Kendall, Kris, and Kardashian West wanted to transform the yard on the house Stanley had been renovating over the last year.

Her husband and mother passed away in 2020, and Stanley bought the house for a fresh start. She had transformed the interior, but she hadn't done any work on the outside of the 25,000-square-foot property.

The losses were traumatic for her, and the Kardashian-Jenner family wanted to help support her through that time.

"I love Lisa with all my heart, so this is the least that I can do for my beautiful friend to help her heal," Kris said.

The trio worked alongside Drew and Jonathan Scott to transform the backyard.

Kendall and Kris were hands-on during the demolition

Before the renovation, Stanley's large yard was mostly bare.

Even though it was big, the space wasn't being used to its full advantage.

The space did have a small pool, but it wasn't the right size for the backyard.

It also had not been taken care of, so it was full of debris before the renovation.

"This yard honestly needs so much love," Kardashian West said before the renovation. "She just hasn't done anything to it, and I don't know if she had any intention to do it."

Kris focused on making the space functional for Stanley's extended family, as she often hosts her children and grandchildren for parties. The Scotts had five weeks to complete the renovation, during which Stanley stayed at a rental home.

Kris and Kendall helped the Scotts with the demolition of the existing backyard, while Kardashian West opted out of the hands-on labor.

"I think I'm busy that day," she joked. "The labor part - Kendall's all yours."

Kendall drove an excavator during the renovation.

The Scotts said they were impressed by Kendall's efforts, particularly when she was using a sledgehammer.

"Not what I expected from a supermodel, but she's definitely got a super swing," Drew said.

Kris, meanwhile, used a jackhammer to help with the demolition.

The backyard looked completely different after the renovation

The team decided to create multiple areas for relaxation on the big property.

They filled in the existing pool, turning it into an outdoor fireplace.

The fireplace was framed by olive trees, which are Stanley's favorite trees.

The Scotts and Kardashian-Jenners staged the area with two couches, a coffee table, and two cushions so Stanley could entertain multiple people in the space at once.

Across from the fireplace, the Scotts built Stanley an expansive outdoor kitchen.

The outdoor kitchen, which is covered by a pagoda, has a grill, refrigerator, and built-in trash can.

The countertops are made with stone, so it will be easy for Stanley to maintain.

A large table sits near the island for additional seating.

And the added pool opened up the yard even more.

The pool was made of the same material as the walkway, so the whole area has a cohesive feel.

It also had a built-in jacuzzi, adding to its luxurious feel.

Drew and Jonathan also built an additional firepit next to the pool, giving the Stanley family plenty of options for entertaining.

Stanley was overwhelmed by the renovation

Kardashian West and Kris revealed the renovation to Stanley alongside the Scotts.

"This is so beyond anything I could have expected," Stanley said of the renovation.

Stanley said the renovation gave her a new energy for the next chapter of her life.

"To come back and see this oasis, I just know that this is the happiness I really need, and I'm looking so forward to it all," she said.

"I feel like I've been given a gift, because I was able to do this for Lisa," Kris said of the opportunity to give back to Stanley on "Celebrity IOU."

"She gets to start making new memories and have a fresh start," she said.
