4. Rooftop Hot Tub Modern House

Maximize vertical space by designing a two-story modern starter house with a rooftop hot tub. White and gray concrete for the house structure, along with floor-to-ceiling windows, make the space bright and airy. Add potted plants and small lounge chairs around the rooftop tub for that luxurious rooftop experience.

Design Tip: Use trapdoors and slabs to create a stylish pergola over the hot tub, offering shade and sophistication.
