Interior Design Basics
What Is Modern Interior Design?
Modern interior design is an interior design style that applies early 20th century modernist principles, such as function before ornament and honest materials, to how a room is planned and furnished.
Its reference points are the Bauhaus school (1919 to 1933), Mies van der Rohe and Le Corbusier, and it differs from contemporary design, which shifts with current trends.
The style’s reputation for white, monochrome rooms holds for exteriors but not for Bauhaus interiors. Around 40 colors were found in the interior of Master House No. 3 in Dessau, behind a white exterior (Elle Decoration, 2019, citing the Bauhaus Dessau Foundation).
What Is Modern Interior Design?
Modern interior design is an interior design style that applies early 20th century modernist principles, such as function before ornament and honest materials, to how a room is planned and furnished.
The word “modern” names a historical movement, not whatever looks current. Design that follows present-day trends is called contemporary design, and it shifts every few years.
Among the recognized styles of interior design, modern is the one tied to a fixed set of rules and a specific period.
Three things get confused with it:
- Modernism, the wider movement that also covered art, literature and architecture
- Mid-century modern, a later offshoot
- Bauhaus, one school among several sources of the style
Publishers also disagree on the details. Decorilla’s guide describes block colors and primary hues, while MasterClass describes a monochromatic palette.
Tarkett lists wood, leather and stone as the materials. Bauhaus-focused guides list steel, glass and concrete. The sections below sort out which description fits which period.
Where Did Modern Interior Design Come From?
Modern interior design grew out of ideas argued between 1896 and 1910, then reached actual rooms through the Bauhaus school, which operated from 1919 to 1933 (UNESCO World Heritage Centre).
Published start dates run from the late 1800s (Decorilla) to the early and mid 20th century (AND Academy). Both hold up, because they measure different things.
The ideas date from the 1890s and the signature furniture from the 1920s. Use in ordinary homes came after World War II, according to Drew and Jonathan, which also produced the offshoot mid-century modern design.
Louis Sullivan wrote that “form ever follows function” in an 1896 essay on tall office buildings (Lippincott’s Magazine, March 1896). Adolf Loos attacked ornament in “Ornament and Crime”, which he later dated to 1908, though scholars trace the first lecture to January 1910 (ACSA Annual Meeting Proceedings).
Loos aimed at the ornamented interiors of earlier eras, a period the wider history of interior design covers.
Walter Gropius founded the Bauhaus in Weimar in 1919. The school moved to Dessau in 1925 and closed in 1933 under political pressure (UNESCO World Heritage Centre).
Its Dessau building, opened on 4 December 1926, wrapped a three-storey glass curtain wall around a reinforced concrete frame (Bauhaus Dessau Foundation).
Le Corbusier’s Five Points of Architecture carried the same logic into plans: pilotis, free plan, free facade, ribbon windows and a roof garden (Museum of Modern Art). Columns carry the load, so interior walls go wherever use calls for them.
After 1933, Mies van der Rohe, Gropius and Josef and Anni Albers moved to the United States, where they kept shaping design (History.com).
Key dates:
- 1896: Sullivan publishes “form ever follows function” (Lippincott’s Magazine)
- 1919 to 1933: the Bauhaus operates in Weimar, Dessau and Berlin (UNESCO World Heritage Centre)
- 1926: Gropius’s Bauhaus building opens in Dessau (Bauhaus Dessau Foundation)
- 1929: Mies van der Rohe completes the Barcelona Pavilion (Architectural Record)
- 1951: the glass-walled Farnsworth House is completed (National Trust for Historic Preservation)
Principles That Define Modern Interior Design
Modern interior design rests on 5 principles: form follows function, less is more, no applied ornament, honest materials, and asymmetrical geometry.
These sit on top of the general principles of interior design that apply to any style, and modern gives each one a specific meaning.
| Principle | Origin | Effect in a room |
|---|---|---|
| Form follows function | Louis Sullivan, 1896 | Shape follows use |
| Less is more | Mies van der Rohe | Fewer objects, clear surfaces |
| No applied ornament | Adolf Loos, Ornament and Crime | Structure and material replace decoration |
| Honest materials | Bauhaus workshops, 1919 onward | Steel, glass, wood and concrete stay visible |
| Asymmetrical geometry | De Stijl, founded 1917 | Straight lines, rectangles, balance by visual weight |
Sullivan’s line concerned skyscrapers. Designers later applied it to every object in a room, which is why modern furniture shows its frame and joints instead of hiding them.
Honest materials appear in the earliest pieces. Gerrit Rietveld built his Red Blue Chair from lumber in the standard sizes available at the time (Museum of Modern Art).
Asymmetry replaces mirrored pairs. In Mondrian’s compositions, pale yellow rectangles are paired with black to offset the heavier red and dark blue (Smarthistory).
A room applies the same trade with furniture: a large dark sofa offset by a small bright chair and a tall lamp. The mechanics of visual balance in a room explain why that arrangement reads as stable.
How Modern Interiors Use Space and Light
Modern interiors replace interior walls with open plans and depend on large glazing for daylight, with artificial fixtures filling in after dark.
Open plans and partitions
The Farnsworth House, completed in 1951, covers 1,586 square feet and has no interior walls except wood partitions around one service core (National Trust for Historic Preservation).
The structure allows it. In Le Corbusier’s free plan, columns carry the load, so walls can go wherever use calls for them (Museum of Modern Art). Mies van der Rohe aimed for continuous flow between inside and outside in the 1929 Barcelona Pavilion (ICON Magazine).
At home, the partition job passes to furniture. Sofa backs, rugs and shelving mark the zones that walls once did, which is ordinary space planning.
Daylight and fixtures
Glass does most of the lighting work in the canonical buildings.
- Bauhaus Dessau: a three-storey steel and glass facade drawn around the workshop wing like a curtain (Bauhaus Dessau Foundation)
- Villa Savoye: ribbon windows, long horizontal bands of glazing (Museum of Modern Art)
- Lamps: designed in the Dessau metal workshop, with over 100 of Marianne Brandt’s designs industrially produced (Bauhaus Dessau Foundation)
Pairing daylight with lamps follows the general rules of light in a room.
Glass costs comfort. The Bauhaus Dessau Foundation has monitored the workshop wing’s glass facade since 2020, logging climate data and cracks.
Edith Farnsworth told House Beautiful in 1953 that she felt like a “prowling animal” behind four glass walls, and she complained that the panes steamed up (National Trust for Historic Preservation).
Colors and Materials in Modern Interiors
Modern interiors pair a neutral base of white, grey and black with a few saturated accents, and they mix industrial materials (steel, glass, concrete) with natural ones (wood, leather, stone).
Color palette
The accent tradition comes from De Stijl. Gerrit Rietveld designed the Red Blue Chair in 1918, and its red, blue, yellow and black scheme was applied around 1923 (Museum of Modern Art).
De Stijl accepted only the three primary colors plus black, white and grey (Canon van Nederland). Bauhaus interiors used red, yellow or blue in focused ways, such as one red wall or one yellow chair (MasterClass).
A single saturated accent against a neutral field follows basic color theory.
Neutral base with one or two accents
- Pro: the accent gives the eye a single focal point
- Pro: swapping one object updates the room
- Con: a third accent breaks the scheme
Strict monochrome
- Pro: matches the palette most publishers describe
- Con: relies on texture and daylight to avoid looking flat
Materials
| Material | Example | Year |
|---|---|---|
| Tubular steel | Breuer’s Wassily armchair | 1925 |
| Steel and glass | Bauhaus Dessau workshop wing | 1926 |
| Travertine, marble and onyx | Barcelona Pavilion | 1929 |
| Molded plywood | Eames lounge chair (LCW) | 1946 |
Dates come from the Metropolitan Museum of Art, the Bauhaus Dessau Foundation, the Twentieth Century Society and the Eames Office.
Marcel Breuer took the tubular steel idea from his bicycle frame. He called the armchair his most extreme work, the most logical and the least cozy (Metropolitan Museum of Art).
Modern does not mean plain stone or cheap stock. The Barcelona Pavilion used white travertine, green Tinian marble and onyx with chrome-plated steel columns, and its richness came from the materials instead of ornament (Twentieth Century Society).
The Eames Office describes the 1946 plywood lounge chair as a classic case of honest materials.
With ornament gone, texture in a room does the work decoration used to do: wood grain, leather, canvas and polished chrome set against each other.
Where the sources disagree
The neutral-palette description and the steel-and-glass description each leave something out.
Palette: MasterClass describes a monochromatic palette, and Decorilla describes block primary colors. Bauhaus records show neither alone: around 40 colors were found in the interior of Master House No. 3 in Dessau, a scheme by Hinnerk Scheper’s wall-painting workshop, while the exterior was white (Elle Decoration, 2019, citing the Bauhaus Dessau Foundation).
After the 1933 closure, those interiors were quickly whitewashed (Elle Decoration).
Materials: Tarkett lists wood, leather and stone, and Bauhaus-focused guides list steel, glass and concrete. The table above explains the split by date: steel and glass belong to the 1920s Bauhaus workshops, plywood and wood to the Eameses’ work in the 1940s.
Both descriptions are accurate for some buildings and some years. For a home today, a neutral base with one saturated accent is the scheme every one of these sources supports.
Which Furniture and Designers Define Modern Interior Design?
Steel-framed seating by Mies van der Rohe and Marcel Breuer, bent-wood by Alvar Aalto, molded shells by the Eameses and Arne Jacobsen, and modular storage by Dieter Rams define the furniture of the style.
| Piece | Designer | Year | Maker |
|---|---|---|---|
| Barcelona chair | Mies van der Rohe and Lilly Reich | 1929 | Knoll |
| Stool 60 | Alvar Aalto | 1933 | Artek |
| Egg chair | Arne Jacobsen | 1958 | Fritz Hansen |
| 606 Universal Shelving System | Dieter Rams | 1960 | Vitsoe |
Makers and dates come from Artek, Fritz Hansen, Vitsoe and the Museum of Modern Art, with 1stDibs Introspective for the Barcelona chair.
Lilly Reich co-designed the Barcelona chair, though Mies left her out of his later account of it (1stDibs Introspective). Knoll’s authorized version still uses a chromed steel frame buffed by hand, with leather cut from a single cowhide.
Aalto chose birch for his earliest furniture at the Paimio sanatorium because he believed patients should never touch a cold surface (MoMA Design Store). Stool 60 has stayed in production since 1933, according to Artek.
A correction to the materials split: the earlier reading of steel by decade and wood by decade does not hold. PIN-UP notes that Aalto launched the stool in solid birch against the chromed steel of Le Corbusier, Mies, Eileen Gray and Breuer, so the split runs by school, not by date.
Jacobsen designed the Egg chair for the lobby and reception areas of Copenhagen’s SAS Royal Hotel (Fritz Hansen). In the 1960s the maker moved to molded foam with fiberglass reinforcement, Dezeen reports.
Rams conceived the 606 as interchangeable wall-mounted units, so storage grows one unit at a time instead of being built in (Vitsoe). Jacobsen and Rams belong to the postwar group profiled in mid-century furniture designers.
Who makes the originals: Herman Miller is the sole authorized Eames manufacturer everywhere except Europe and the Middle East, where Vitra holds that role (Eames Office).
Vitra’s own pages date its licence from Herman Miller to 1956 in one place and 1957 in another. The two companies split the rights in 1984, per Vitra.
How Does Modern Differ From Contemporary, Mid-Century Modern and Minimalism?
Modern is a defined historical style, contemporary follows current trends, mid-century modern is the postwar branch, and minimalism is a 1960s art movement whose name interiors borrowed.
| Style | Period | Materials | Ornament |
|---|---|---|---|
| Modern | Early to mid 20th century | Steel, glass, concrete, wood | None applied |
| Contemporary | Current, always shifting | Light wood, recycled glass and plastic | Softer edges, sculptural touches |
| Mid-century modern | About 1945 to 1970 | Wood, molded plywood, fiberglass | Organic forms, no embellishment |
| Minimalism | 1960s, New York art scene | Industrial, fabricated | Reduced forms, no narrative |
Mid-century modern: Britannica credits Cara Greenberg’s 1984 book Mid-Century Modern: Furniture of the 1950s with popularizing the term, which had been used sporadically before.
Dates vary by source. Britannica runs the style from the 1930s to the mid-1960s, while Wikipedia runs it from 1945 to 1970.
The branch has its own palette and furniture rules, laid out in a mid-century modern interiors guide.
Minimalism: Donald Judd’s 1964 essay “Specific Objects” defined it, and Judd himself rejected the label (Whitney Museum of American Art). The National Gallery of Art adds that Judd aimed at the illusionism of European modernism, so minimalism set itself against the movement modern interiors come from.
Minimalist interiors keep the reduction and drop the functional doctrine.
Scandinavian design reached North America through the 1954 exhibition Design in Scandinavia, which drew 660,000 viewers on tour (1stDibs Introspective). It presented simple, curvilinear wooden furniture as a foil to glass-and-steel skyscrapers, which is the practical difference from steel-framed modern, and the full profile sits under Scandinavian interior design.
Decision rule:
- Want a defined look and icon furniture: modern
- Want flexibility and current materials: contemporary
- Want wood, curves and postwar pieces: mid-century modern
- Want the least possible on show: minimalism
How to Apply Modern Interior Design at Home
Apply it in six steps: clear the layout and daylight, set a neutral base, add one accent color, choose two or three materials, buy one or two anchor pieces, and finish with lighting.
- Clear the layout and windows. Move furniture off the glass and open sight lines before buying anything.
- Set a neutral base. Paint walls and large surfaces white, grey, black or an earth tone.
- Add one accent color, limited to a single wall or object.
- Choose two or three materials and let steel, wood, glass or leather show as what they are.
- Buy one or two anchor pieces with exposed frames and low profiles.
- Light the room, then edit. Remove objects until each surface has one job.
Test accents on screen first. A color scheme generator for rooms shows a neutral base with one accent before any paint is bought.
Size the lighting before choosing fixtures. An LED lighting requirement calculator estimates how much light the floor area needs.
Le Corbusier’s gardener’s lodge at Villa Savoye shows the method at small scale: a 45 m2 mini-villa for a family of 3, with a sliding partition and built-in storage under the windows (Centre des monuments nationaux).
Common mistakes:
- Three or four accent colors instead of one
- Ornate pieces mixed in with modern ones
- Copying a showroom layout into a room with different windows
When Modern Interior Design Does Not Fit
Modern interior design fits poorly in 4 situations: households with many belongings, rooms that echo, buildings that lose heat through large glass, and streets where the architecture depends on ornament.
The Savoye family noticed water leaking through the skylights and along the ramp shortly after moving into Le Corbusier’s villa, and the house was hard to heat. They visited only on sunny days (Centre des monuments nationaux).
Adolf Loos built the Looshaus on Vienna’s Michaelerplatz in 1910. Its severe facade provoked such resentment that he was made to add flower boxes (National Gallery of Victoria).
Storage: the uncluttered rule assumes belongings have somewhere to go. Modern solved that with built-in units or modular systems, and a household with neither keeps everything on show.
Echo: glass, concrete and tile reflect sound, and open plans give the reflections room to build. BMC Audio Visual advises modeling reverberation time before ordering glass.
Soft layers absorb part of it, and window treatments do double duty on glass walls.
Partial screens help too when a room is too open for the household, as in dividing a large living room into zones.
Pros of modern interior design:
- Clear rules that speed up decisions
- Core furniture that stays in production, so pieces can be added later
- Daylight and open layouts in the right building
Cons:
- Hard surfaces echo in open rooms
- Storage has to be planned in advance
- Large glazing needs climate planning
- The rules clash with ornate or period architecture
Skip the strict version when the household owns many objects and the room has hard shells. A softened version with rugs, curtains and planned storage fits those homes better.
Modern Interior Design FAQ
What does a modern living room, kitchen or bedroom look like?
Each room applies the same rules: a neutral base, one accent color, visible materials and cleared surfaces.
A living room has low-profile seating and open sight lines. A kitchen relies on built-in storage and empty counters, and a bedroom keeps furniture and objects to a minimum.
Is modern interior design warm or cold?
It can be either. Steel, glass and concrete lean cold, while birch, leather and warm neutrals lean warm.
Publishers describe it both ways, so the materials you choose decide the mood, not the label.
Can modern interior design work in a small space?
Yes. Cleared surfaces and open sight lines make small rooms read larger.
Planned storage matters more there, because nothing can sit out without breaking the scheme.
Can modern and contemporary elements share a room?
Yes, and they blend easily because contemporary design borrows from modern. Let one style set the base, keep modern’s neutral palette, and add contemporary materials such as lighter woods as accents.
Which flooring suits a modern interior?
Polished concrete, wide-plank wood and stone fit best. Travertine paved the Barcelona Pavilion (Twentieth Century Society), and Mies van der Rohe used it again on the Farnsworth House terraces (National Trust for Historic Preservation).
Hard floors echo in open rooms, so a rug usually earns its place.
What is modern farmhouse style?
Modern farmhouse pairs farmhouse materials, such as reclaimed wood and shiplap, with clean modern lines.
It keeps rustic texture and warmth that strict modern design leaves out.
Is Bauhaus the same as minimalism?
No. Bauhaus is a German design school (1919 to 1933) built on function and geometry, while minimalism emphasizes reduction and visual calm, according to Reimagine Home.
Bauhaus also used color, so the two overlap without matching.
Where to Spend Money in a Modern Interior
Modern interior design rewards spending on one licensed anchor piece and a planned layout, not on a full set of originals. Plain, well-proportioned furniture carries the rest of the room.
The order saves money:
- Plan layout and storage
- Buy one licensed anchor
- Fill gaps with plain pieces
Authorized prices differ by channel. The Eames Office lists the LCW at $1,421.25 to $1,871.25, while Herman Miller’s store lists the unupholstered version at $2,575 (checked 30 September 2026).
Copies cost far less. 1stDibs Introspective counts more than 100 companies selling imitations of the Barcelona chair.
Upkeep follows the glass and stone. In 2020 the National Trust for Historic Preservation sought $10 million for Farnsworth House repairs, long-term maintenance and a flood lift.
The trade-off is fewer pieces, each priced above its copy. Price the whole room first with a renovation cost calculator for the room, then choose the anchor.
