The Utonium Residence (107 Pokey Oaks South, Townsville, USA) is the home of both Professor Utonium and the Powerpuff Girls. It is often referred to simply as "the House" throughout the series. Inside are many rooms, each with unique purposes. It is located in the Pokey Oaks neighborhood of the city of Townsville.

The Utonium residence is a striking example of stylized mid-century modern architecture, defined by its bold geometric simplicity and clean, minimalist design. The house is primarily a tall, rectangular white structure with a flat roof and smooth, untextured exterior walls. Its most recognizable feature is the trio of evenly spaced circular windows positioned high on the front façade, giving the building a distinctive, almost abstract expression. Below them sits a bright red front door centered on the structure, creating a strong visual contrast against the otherwise pale exterior.

The house appears to stand approximately two full stories tall, with an additional lower level housing Professor Utonium’s laboratory. Based on its proportions relative to the characters and surrounding yard, the structure can be estimated at roughly 30–35 feet tall, 40–45 feet wide, and 30–35 feet deep, though the interior layout often feels larger due to the show’s stylized perspective and occasional exaggerated scaling. The flat roofline and cubic massing give the home a slightly box-like silhouette, reinforcing its clean, almost futuristic aesthetic.

The front yard is modest and neatly maintained, bordered by simple landscaping. A straight concrete walkway leads from the sidewalk to the red front door, cutting through a small green lawn. Minimal shrubbery and rounded bushes sit near the base of the house, complementing the smooth geometry of the building without cluttering its façade. The driveway, positioned to one side, leads to an attached garage integrated seamlessly into the home’s rectangular form.

The color palette of the exterior is intentionally restrained: white walls, pale blue-tinted windows, muted greenery, and the single vibrant red door acting as the focal point. This simplicity allows the structure to feel both domestic and iconic—ordinary enough to blend into Townsville’s suburban setting, yet visually unique enough to be instantly recognizable.

From a distance, the house resembles a clean architectural model—almost toy-like in its symmetry and clarity. Its design reflects Professor Utonium’s personality: orderly, efficient, modern, and slightly unconventional. Though it appears modest from the outside, the home contains expansive interior spaces, including the large laboratory and hologram chamber beneath it, making it far more complex than its simple exterior suggests.

Overall, the Utonium house stands as one of Townsville’s most recognizable landmarks: a pristine white cube with three round windows and a red door—unassuming on the surface, yet home to science, family life, and the Powerpuff Girls.

Bathroom

The bathroom is all white, with a toilet, 3 sinks, and claw-foot bathtub big enough for all three girls plus many more. There are towels hanging on the wall: pink, blue, and green ones (reflecting the colors of the Girls themselves), and a plush purple rug in front of the door. Blossom and Bubbles love bath time, but Buttercup hates it.

Kitchen

The Powerpuff Girls’ kitchen is as modern and orderly as the rest of the Utonium household, rendered in a clean mid-century style that blends warmth with efficiency. Pale green walls, tiled floors, and wide picture windows flood the room with light, while dark cabinetry and stainless steel appliances give the space a sleek, contemporary feel. A compact cooking area lines one side of the room, complete with a range, countertop workspace, and overhead cabinets, all kept meticulously tidy. Hanging above the central dining area is a simple pendant lamp, anchoring the room visually and reinforcing the kitchen’s calm, domestic atmosphere. At the heart of the kitchen is a distinctive booth-style table with tall-backed chairs, where the Professor often serves meals and reads recipes while cooking.

This table is most famously associated with his frequent preparation of liver and onions—an earnest attempt at nutritious home cooking that the girls routinely greet with visible dismay. Whether the girls are seated expectantly with plates and milk or slouched in reluctant anticipation, the kitchen functions as a recurring stage for quiet family moments, gentle humor, and everyday life between battles. It is a space defined not by chaos or superpowers, but by routine, affection, and the Professor’s unwavering commitment to being both scientist and father.

The Girls' Bedroom

The Girls’ Bedroom is a bright, cheerful space that perfectly reflects the personalities of the Powerpuff Girls. Dominated by shades of pink, the room is filled with soft colors, rounded shapes, and playful décor. At the center is a large shared bed with a distinctive comforter divided into three sections—pink, blue, and green—representing Blossom, Bubbles, and Buttercup. The headboard is especially eye-catching, featuring a large pink heart emblazoned with the initials “PPG,” reinforcing both their sisterly bond and superhero identity. A heart-shaped rug lies on the floor beneath the bed, while a fluffy ceili A nightlight adds to the room’s cozy, almost dreamlike atmosphere. Surrounding the bed is an abundance of furniture and personal items, including dressers, shelves, and nightstands,

most of them pink and decorated with toys, figurines, and stuffed animals scattered throughout the room. Three circular windows line one wall, letting in natural light and giving the space an open, airy feel, while a door leading to a small balcony or exterior walkway is visible on the opposite side. One table holds the iconic hot phone connected directly to the Mayor of Townsville, which frequently rings at inconvenient times—often just as the girls are settling down for the night. Overall, the room balances sweetness and functionality, serving as both a comforting bedroom and a reminder that even here, the girls are never far from their superhero duties.

Professor Utonium's Bedroom

Professor Utonium’s Bedroom is a clean, minimalist space that reflects his orderly personality and scientific mindset. The room is centered around a neatly made bed with a solid wooden headboard and a simple blue bedspread. On either side of the bed are two matching nightstands, each topped with a lamp that provides warm, practical lighting for late-night reading or quiet moments of rest. The overall color palette is subdued, relying on soft neutrals and muted tones that give the room a calm, functional atmosphere rather than a decorative one. The bedroom also features three square windows set high along the wall, allowing natural light to filter in during the day while maintaining privacy. These windows help balance the room’s otherwise enclosed, almost box-like layout, giving it a slightly

airy feel. Additional furnishings are kept to a minimum, reinforcing Professor Utonium’s no-nonsense lifestyle; everything appears deliberately placed and free of clutter. The result is a modest, well-organized bedroom that serves purely as a place for rest, fitting for a devoted scientist and single father whose life largely revolves around his work and his daughters.

Living Room

The Utonium living room is a wide, open, double-height space built around a mid-century modern layout. A floating staircase sits on the left side with dark blue steps and railings, leading up to an overlooking balcony that wraps around the back and right sides of the room. Large sliding glass doors open onto the backyard beneath the upper landing. The tall stone-textured chimney stands slightly right of center, containing a modern corner fireplace and built-in display niches. The room’s décor features scientific artwork, including DNA prints, atomic diagrams, and abstract maps, reinforcing Professor Utonium’s blend of home and laboratory aesthetic.

The main floor is arranged with a blue mid-century sofa positioned near the chimney, framed by matching side tables and lamps, with a sleek white coffee table in front. Opposite it sits a vintage-style TV cabinet with books and décor on its low shelving. Soft blue carpeting covers the room, bringing warmth to the geometric architecture. A small pedestal table with a whimsical pink “brain lamp” stands at the base of the stairs, next to a planter full of large leafy plants. Altogether, the living room feels open, bright, functional, and distinctly stylized—perfect for the Utonium household and the Powerpuff Girls’ lively daily life.

Professor Utonium's Laboratory

Professor Utonium's laboratory is a sprawling, multi-level research space filled with the crisp glow of cool blues and whites, giving it an atmosphere of both precision and wonder. The upper platforms and long countertops are lined with an eclectic mix of scientific instruments—delicate glass beakers, Erlenmeyer flasks, test tubes suspended on metal racks, and bubbling chemical setups that hint at constant experimentation. Sleek machines with dials, gauges, and spinning reels hum quietly along the walls, while chalkboards filled with equations—some serious, some whimsically crossed out—reflect the professor’s blend of brilliance and absent-minded creativity. Sunlight from large overhead panels casts bright geometric patterns on the tiled floor, illuminating scattered papers, microscopes, and partially assembled inventions that give the space a feeling of perpetual scientific discovery.

Deeper inside the lab, long workbenches stretch into a central open area designed for movement between experiments, with rolling carts and three-dimensional models contributing to its organized chaos. Stairs lead down from the living area above, allowing the professor to descend directly into a world of research at any moment, while clusters of high-tech equipment—oscilloscopes, computers, mysterious consoles, and experimental power sources—fill the far end of the room. Though brimming with advanced technology, the laboratory retains a warm, almost handmade charm: beakers contain pastel liquids, strange devices sit mid-construction, and a single broken-in stool waits patiently at a terminal. More than just a workplace, Utonium’s lab is a sanctuary of imagination and science, the birthplace of the Powerpuff Girls and the heart of the professor’s tireless pursuit of innovation.

Hologram Room

The Hologram Room in the Utonium household is a high-tech, hard-light training chamber designed by the Professor to simulate real combat scenarios for the girls. From the outside, it appears as a stark white, cube-shaped room lined with pale blue grid lines, viewable only through a reinforced observation window connected to the adjacent control booth. When inactive, the chamber is completely empty and eerily silent, . The Professor operates the room from a complex console filled with buttons, switches, monitors, and a large microphone, allowing him to construct fully interactive monster encounters. Under his control, the room can project convincing hard-light environments—such as the giant slug battle Buttercup trains in—complete with tactile feedback, destructible elements, and immersive surroundings that dissolve back into the blank grid when the simulation ends.
