Glossary. Architecture, BIM, planning and interior design — in plain terms.

A single wall within a room finished or coloured differently from the others, used to add visual interest or highlight a focal point without committing the whole space to a bold choice. Effective when it supports the room's existing material palette; arbitrary when picked in isolation from everything else in the space.

Materials and design choices — soft furnishings, acoustic panels, ceiling treatments — used to control sound reflection and reverberation within a space, distinct from soundproofing between spaces. It matters more than most clients expect in double-height or hard-surfaced rooms, where an otherwise beautiful space can be genuinely unpleasant to talk in.

Incorporating natural elements — daylight, plants, natural materials, views to outdoors — into interior design to improve occupant wellbeing, grounded in real, measurable effects on mood and productivity rather than decorative greenery for its own sake. It works best planned alongside the lighting plan and fenestration, not added as an afterthought.

The route people actually walk through a space to get from one point to another, planned with real width and clearance rather than assumed to fit around whatever furniture ends up placed. Poor circulation is one of the most common reasons a well-finished interior still feels cramped or awkward to live in.

The specific set of colours chosen for a space and how they're distributed — dominant, secondary, accent — coordinated with material palette and lighting rather than picked as isolated paint chips. The same colour reads differently under the lighting plan's actual fixtures than it does on a swatch under daylight.

Designing furniture and layout dimensions around how the human body actually sits, reaches and moves — counter heights, seating depth, clearance for a wheelchair or a child — rather than standard catalogue sizes alone. It matters most in kitchens, workspaces and bathrooms, where a few centimetres wrong makes a space genuinely uncomfortable to use daily.

The arrangement, size and proportion of windows and openings in a building's facade, considered for daylight, view and ventilation together rather than window placement decided purely on the exterior elevation's appearance. Interior design and architecture genuinely share this term, since fenestration decided at Design Development directly shapes what the lighting plan has to work with later.

The document listing every material, finish and product specified for every surface and room — flooring, paint, tile, hardware — cross-referenced so a contractor knows exactly what to install where without guessing from a mood board alone. It's what turns a design intention into something actually procurable and installable.

The element a room is deliberately designed to draw the eye toward first — a fireplace, a feature wall, a piece of art — used to anchor the rest of the layout and material choices around it. A room without one usually reads as visually flat, regardless of how good its individual elements are.

The specific arrangement of furniture pieces within a planned space, tested against real clearances — walking paths, door swings, seating distances — not just how it looks in a rendering. A layout that looks balanced on a flat plan can still fail in the room if a drawer can't actually open.

Combining multiple elements at different depths and heights — rugs over flooring, lighting at several levels, textiles over furniture — to give a space visual and tactile depth rather than a flat, single-layer look. A room with a good material palette can still feel unfinished without enough layering to hold it together.

The drawing specifying every light fixture's location, type and switching, layered with ambient, task and accent lighting rather than a single ceiling fixture per room. It has to be coordinated with the reflected ceiling plan and structural grid early, since retrofitting a missed switch point after the ceiling is closed means opening it back up.

The finalised, coordinated set of materials and finishes chosen for a project — a handful of textures, tones and surfaces that work together across every room rather than each space picked in isolation. It's the mood board's ideas made specific and buildable, tied directly into the finish schedule.

Custom-built wood joinery — cabinetry, wardrobes, panelling, built-in shelving — fabricated specifically for a project rather than bought off the shelf. It's usually where an interior's budget and craftsmanship show most clearly, and where dimensional accuracy from the space plan matters most, since a built-in doesn't forgive a measurement error the way loose furniture does.

A curated collection of images, materials and colours communicating a design direction's overall feel before final specifications are locked — a conversation tool with a client, not a construction document. It has to translate into an actual, procurable material palette and finish schedule, or it stays a nice idea nobody can build from.

A drawing showing the ceiling as if reflected onto the floor plan below it — light fixtures, ceiling levels, HVAC diffusers, beams — the coordination drawing that catches conflicts between lighting, structure and services before the ceiling is actually built, not after.

A repeated pattern of elements — evenly spaced windows, a repeating tile motif, alternating materials — that creates visual movement and continuity through a space. It ties an interior back to the building's own facade rhythm and structural grid rather than treating the inside as unrelated to the outside.

How the size of furniture, fixtures and architectural elements relates to each other and to the human body within a space — an oversized sofa in a small room, or fixtures too delicate for a double-height volume, both break this even when individually well-chosen. It's judged in the room, not on a rendering.

Textile-based interior elements — curtains, cushions, rugs, upholstery — as distinct from fixed millwork or hard finishes, usually the last layer specified since they're easiest to adjust and most directly carry a space's colour palette and texture. They're also the cheapest way to meaningfully update a space without touching anything structural.

Arranging rooms and furniture layout to match how a space will actually be used — circulation paths, furniture clearances, sightlines — worked out before finishes or material palette are chosen. Get this wrong and no amount of finish quality afterward fixes a room that simply doesn't work for how people move through it.

A single furniture item or fixture — an oversized light, a sculptural chair — chosen deliberately to anchor a room and carry more visual weight than everything around it. It only works if the rest of the room is designed to support it rather than compete with it for attention.

A physical sample of a material or finish — fabric, paint, stone, laminate — used to confirm colour and texture in person before it's specified in the finish schedule, since screen and print colour rarely match reality precisely. A swatch approved under showroom lighting still needs checking against the room's actual light.

Arranging elements so visual weight is distributed evenly across a space — either mirrored exactly (symmetry) or balanced through different but equivalent elements (asymmetrical balance). Both are deliberate compositional choices in a furniture layout, not something that happens automatically once furniture is placed in a room.

The tactile and visual surface quality of a material — rough stone against smooth plaster, matte against gloss — used deliberately to add depth to a space that a single flat colour palette can't provide on its own. Overlooking texture is a common reason a technically well-planned room still feels visually thin.

Design that helps people orient themselves and navigate a space intuitively — signage, but also lighting, material changes and sightlines used as implicit cues — most relevant in larger or public interiors like offices, schools and hospitality, where a visitor has no existing mental map of the building.
