Residential renovation projects that treat color and graphics as primary design tools produce interiors that feel distinctive and intentional. The refurbishment of an Edwardian house in Hackney, London demonstrates how graphic designers applied their professional visual language to their own living space. Color zones, geometric shapes, and strategic light manipulation transformed a period home into a gallery of interconnected spatial experiences. This approach to architectural design and building envelope strategies shows how interior interventions can redefine how occupants move through and perceive their home without altering the external structure.
Color as an Architectural Tool for Defining Space
Color in interior architecture does more than decorate surfaces. It defines zones, directs movement, and communicates function. In this renovation, minty green marks all new-built elements on the ground floor, wrapping through the toilet, kitchen, and extending to the rear garden wall. This consistent color coding helps occupants read which parts of the building are original and which were added during renovation, creating a legible architectural narrative without requiring written explanation.

Color Spill and Threshold Effects
When painted interior surfaces are visible through doorways, the color spills into adjacent spaces and creates anticipation. The peach-colored toilet interior becomes partly visible when the door is ajar, introducing a warm accent into the minty green hallway without needing to paint the hallway itself. This technique delivers visual interest at a low material cost and can be reversed easily if the homeowner’s tastes change. Showcase home design strategies often use similar color reveal techniques to create surprise moments within open floor plans.
Painting Sequence and Surface Preparation
Painting over existing plaster requires cleaning the surface to remove grease and dust, filling cracks with flexible filler, and applying a mist coat of diluted emulsion as a primer. Unpainted pink plaster left exposed on restored walls must be sealed with a clear matte sealer to prevent dusting and make the surface wipeable. The minty green walls received two coats of premium emulsion with a satin finish that reflects light differently than matte, adding subtle variation as the sun moves across the room during the day.
Light and Transparency Through Circular Openings
Circular shapes puncture walls throughout the house to control light transmission and create framed views between rooms. Some circles are transparent, allowing direct light through, while others use mirrored surfaces that reflect daylight deeper into the plan. The kitchen window, described by the designers as an oculus, acts as a time marker by casting a moving patch of sunlight across the room that shifts position throughout the day. This design borrows from the concept of the Pantheon dome in Rome, where a single opening tracks solar movement across the interior.

Circular openings also frame views between spaces. A round window punched through a wall between a hallway and a dining area creates a framed picture of the room beyond, drawing people into and through the house as the view changes with their position. The size of circular openings should relate to the room dimensions: an 18-inch diameter circle provides a porthole effect, while 36-inch circles create more generous connections suitable for passing plates or casual conversation through the opening.
Borrowed Light Strategies for Dark Corridors
Edwardian terraced houses typically have long, narrow floor plans with limited natural light penetration beyond the front and rear rooms. Puncturing the walls between the front and middle rooms with circular openings allows daylight from the larger windows to reach the darker central zone. A home office in a small space benefits from this borrowed light arrangement because the work area receives daylight without needing its own window. Interior glazing with clear glass transmits the most light, while frosted or textured glass provides privacy for rooms like bathrooms while still admitting 70 to 80 percent of available daylight.
Material Choices That Honor Building History
Leaving original pink plaster exposed on restored walls communicates the age and history of the Edwardian structure while avoiding the waste and cost of re-plastering. Exposed plaster requires assessment for structural soundness and lead content before being left as a finished surface. Loose or friable sections are stabilized with a consolidant, and cracks wider than 1/8 inch are filled with lime-based filler that matches the original material’s vapor permeability. Passive house design lessons emphasize the importance of vapor-permeable assemblies in older buildings, which applies directly to this approach of working with existing materials rather than sealing them behind vapor-impermeable paint or drywall.
The contrast between exposed old plaster and smooth new painted surfaces creates a dialogue between old and new. The rough texture of original lime plaster catches light differently than modern gypsum board, adding visual depth. Maintaining these historical surfaces reduces renovation waste and preserves the embodied carbon already invested in the original construction. A typical renovation generates 25 to 40 pounds of waste per square foot; retaining existing wall finishes cuts that figure substantially while keeping original craftsmanship visible.
Graphic Shapes and Staircase Design
The staircase becomes a vertical canvas for graphic intervention. An over-scaled painted stair on the wall draws the eye upward, while reflective circular shapes connect the different levels by capturing sunlight from the rooflight and bringing it down through the building. This treatment makes the stairwell feel like a continuous vertical gallery rather than a purely functional circulation space. V-shaped house designs and passive house principles often treat stairwells as light wells, using similar strategies of reflective surfaces and vertical sight lines to distribute daylight between floors.
Staircase Dimensions and Safety Considerations
Building codes for residential staircases require a minimum tread depth of 10 inches and a maximum riser height of 7.75 inches. The painted graphic on the wall must not create visual confusion that makes individual steps harder to read, particularly for older residents or visitors. Contrast between the stair treads and risers should be maintained even when bold colors are applied nearby. The circular mirrors in this stairwell are positioned at least 36 inches above each tread to avoid headroom conflicts and positioned to catch direct or reflected light from the rooflight above.
Handrail placement follows code requirements for both sides of stairs wider than 44 inches and a minimum 36 inches of continuous handrail on at least one side. The graphic elements on the wall should not interfere with the handrail mounting or create glare that distracts users when descending. Paint finishes used on stairwell walls benefit from scrubbable matte or eggshell sheens that accept cleaning without showing marks from hand contact.
Small Space Strategies for Bathrooms and Kitchens
Compact bathrooms in period home renovations require every surface to serve multiple purposes. Painting the entire room in a strong color like vivid peach creates an immersive experience that makes the small space feel intentional rather than cramped. The color envelops the occupant so the walls seem to recede, reducing the perceived confinement of a tight footprint. A typical Edwardian house toilet measures 4 by 5 feet, which benefits from full-room color treatment that eliminates the visual breaks that draw attention to limited dimensions.
Coat Cupboard as Color Moment
Utility spaces like coat cupboards rarely receive design attention, but painting their interiors in dramatic color turns them into miniature experiences. The peach interior of the coat cupboard in this project spills color into the hallway each time the door opens, creating a recurring surprise throughout the day. Mediterranean-style home designs with spa bathrooms similarly use unexpected color moments in transitional spaces to elevate the sensory quality of the home. This technique costs a single quart of paint and can be completed in an afternoon, making it one of the highest-impact, lowest-cost interventions available in any renovation project.

The kitchen’s curved red extractor hood projects from the wall like a nose, marking the cooking zone with a sculptural element that doubles as functional ventilation. Custom-fabricated metal hoods of this type cost $800 to $2,500 depending on the complexity of the curve and the finish. The red color ties into the graphic language of the house while serving the practical function of identifying the cooking area within an open-plan kitchen layout.
Designing a renovation around a clear visual concept reduces decision fatigue during construction and ensures the finished home feels cohesive rather than accumulated. The graphic designers’ approach of using color to code new versus old construction, circular openings to control light and views, and bold moments in small utility spaces demonstrates how creative direction can transform a standard Edwardian terrace into a spatially rich environment. House-within-a-house design strategies for maximizing site potential share this principle of using architectural intervention to reshape how occupants experience volume and light within an existing structure, proving that impactful design depends less on budget than on clear conceptual thinking applied consistently throughout a project.
