Architectural Context in Nepal

1

This section covers the materials, technology, and architectural elements characteristic of the Licchavi, Malla, Shah, and Rana periods of Nepalese history, along with the traditional timber construction system and its key elements.

2

Overview of Historical Periods Period Approx.

3

Era Key Architectural Characteristics Licchavi c.

4

4th–9th century CE Earliest datable stone and brick architecture in the Kathmandu Valley; stone sculptures, water conduits (hiti/dhunge dhara), early temple forms; foundation of later Nepalese architectural vocabulary Malla c.

5

12th–18th century CE Golden age of Newar architecture: tiered pagoda temples, palace complexes (Durbar Squares), courtyards (chowks), extensive brick-and-timber construction with elaborate wood carving; urban form of Kathmandu, Patan, Bhaktapur consolidated Shah 1768 CE onward (unification) Continuation and adaptation of Malla-era typologies; introduction of some European- influenced elements in select palace works; expansion of settlements beyond the Valley Rana 1846–1951 CE Strong Neo-Classical/European (particularly British colonial and Baroque-influenced) palace architecture (e.g. grand Rana palaces); use of lime plaster, classical orders, symmetrical facades, imported materials alongside local craftsmanship Traditional Building Materials Material Types & Application Brick Sun-dried (adobe) and burnt (traditional “dachi apa” face bricks); used for structural walls and decorative facades; laid in mud or lime mortar Stone Used for plinths, foundations, water spouts (dhunge dhara), paving, and stone sculpture/idols; locally sourced Timber Sal and other hardwoods; used structurally (posts, beams, struts) and decoratively (carved windows, doors, tympanums) Metal Copper and its alloys (gilded/gajur finials, repousse work), iron (fittings), bronze (ritual/sculptural elements) Traditional Timber Construction & Elements Doors (Kachapot/Sano Dhoka): low, carved timber frames with lintels bearing decorative tympanums (torans); ornamentation reflecting the significance of the structure.

6

Windows: distinct typologies including the tiki jhya (lattice/net window), sano jhya (small window), and the ornately carved bou jhya (bride's/central projecting window) used on principal facades.

7

Posts and beams (thams and darts): timber posts supporting horizontal beams; often carved with deities, floral, and geometric motifs, especially at temples and palaces.

8

Struts (tunala/pau): diagonal carved timber brackets supporting projecting eaves and roof loads, frequently the most elaborately carved structural-decorative element.

9

Roofs: multi-tiered sloping roofs finished with fired clay tiles (jhingati); tiered temple roofs diminish in size upward, each supported by struts.

10

Carving: deep relief wood carving on struts, tympanums, window frames and cornices depicting deities, mythical creatures, and geometric/floral patterns — a defining feature of Newar craftsmanship.

1

This section covers the major typologies of traditional Nepalese architecture — residential, religious, monastic, palatial, and urban public typologies — with reference to their geometric forms, elemental details, materials, and scale/proportion.

2

Residential and Palace Typologies Residential (traditional Newar house): typically 3–4 storeys, narrow street frontage, load-bearing brick masonry with timber floors, ground floor for shop/storage/livestock, upper floors for living, top floor (chhen) traditionally used as kitchen/attic.

3

Palaces (Durbars): large multi-courtyard complexes combining royal residence, administrative, and ceremonial functions; principal facades richly ornamented with carved windows (e.g. the 'Golden Window'), surrounding a hierarchy of chowks.

4

Religious Typologies Typology Description Tiered temples (pagoda-style) Multi-roofed temples with successively diminishing tiers (usually 2, 3, or 5), each roof supported by carved struts; sanctum (garbhagriha) at the core; e.g.

5

Nyatapola, Pashupatinath Shikhara temples Temples with a tall, curvilinear or stepped tower-form superstructure (shikhara) over the sanctum, of North Indian derivation; typically masonry construction Stupas and Chaityas Hemispherical/dome-form Buddhist monuments enshrining relics or symbolizing the enlightened mind; chaityas are smaller votive stone/masonry monuments, often with the four-Buddha/eye motif (e.g.

6

Swayambhu, Boudha) Dyo Chen (god- houses) Small shrine buildings within courtyards housing a deity, often integrated into residential or monastic courtyard complexes Maths (monastic residences) Residential-institutional buildings historically housing religious teachers/ascetics, combining residential and ceremonial functions Urban and Public Typologies Typology Description Bahals / Bahils Buddhist monastic courtyard complexes (viharas);

7

Bahals are typically larger, formal quadrangles with a shrine on the main axis, Bahils are smaller/simpler variants Patis / Sattals Open, pillared rest shelters (pati — smaller, roadside; sattal — larger, often multi-purpose) for travelers, community gatherings, and ceremonies Dabalis Open public platforms/squares, often used for festivals, chariot processions, and public gatherings Lachi / Nani / Chowks Lachi: a neighbourhood/street cluster unit;

8

Nani: a small enclosed residential courtyard cluster;

9

Chowk: a courtyard, the basic spatial unit organizing traditional Newar settlements Dhunge dharas Traditional stone spout water conduits, often within sunken courtyards (hitis), fed by a traditional gravity-based conduit/canal system Mandaps Open pavilion structures, typically used for ceremonial or ritual gatherings Geometric form, elemental detail (carved struts/windows/torans), material palette (brick-timber-stone), and human-scaled proportion are common threads unifying these typologies despite their functional diversity.

This section covers the general architectural typologies and functional, technological, and aesthetic dimensions of ethnic/vernacular houses across Nepal's major physiographic regions — Himalayan/mountain, hill, and Terai.

2

Physiographic Regions and Vernacular Typologies Region Typical Vernacular Typology Key Characteristics Himalayan/mountain (high altitude) Sherpa, Dolpo, Mustang/trans- Himalayan houses Flat or low-slope roofs (low precipitation as snow more than rain), stone/rammed-earth walls (thick, for insulation), small window openings, compact plan, cattle sheltered on ground floor for warmth transfer Mid-hill (hill region) Newar, Gurung, Magar, Tamang, Rai/Limbu houses Sloped roofs (thatch or slate/stone shingles) for higher rainfall, stone or mud-brick/timber walls, verandahs, courtyard clusters (in Newar settlements), livestock at ground floor Terai (plains) Tharu, Madhesi vernacular houses Bamboo/timber frame with mud/wattle-and-daub infill walls, thatched roofs, raised plinths (flood protection), open verandahs for hot-humid climate ventilation, often decorated exterior wall art (Tharu houses) Functional, Technological & Aesthetic Dimensions Functional: vernacular forms respond directly to livelihood (agro-pastoral vs. farming), climate (insulation vs. ventilation needs), and available construction skill/labour.

3

Technological: use of locally available materials (stone, mud, bamboo, thatch, timber) and construction techniques passed through community/craft tradition rather than formal engineering design.

4

Aesthetic: vernacular decoration (e.g.

5

Tharu wall paintings, Newar wood carving, Mustang-style whitewashed walls with maroon/ochre bands) expresses cultural/ethnic identity and is typically integrated with functional elements rather than applied independently.

6

Vernacular houses across all regions commonly integrate livestock shelter, storage, and living space within a single compact building footprint, reflecting agrarian livelihoods.

This section covers the criteria and procedure for World Heritage Site nomination/enlisting, the byelaws and building control norms applicable to such sites in Nepal, and the principles and process of architectural conservation.

2

World Heritage Site Nomination & Enlisting A site is nominated by the State Party (Nepal, via the Department of Archaeology) to UNESCO's World Heritage Committee, based on meeting one or more of the ten selection criteria (cultural criteria i–vi and/or natural criteria vii–x).

3

The site must demonstrate Outstanding Universal Value (OUV), along with authenticity (for cultural sites) and/or integrity, and have an adequate legal/management protection system in place.

4

The Kathmandu Valley World Heritage Site comprises seven monument zones:

5

Kathmandu Durbar Square, Patan Durbar Square, Bhaktapur Durbar Square, Swayambhunath, Boudhanath, Pashupatinath, and Changu Narayan.

6

Lumbini (birthplace of Lord Buddha) is Nepal's other major inscribed cultural World Heritage Site.

7

Byelaws and Building Control Norms Special heritage/monument-zone byelaws restrict building height, material, and form within designated core and buffer zones to protect the visual and physical integrity of the heritage site.

8

Building control norms in these zones typically mandate traditional material use (brick, timber) and restrict modern materials (RCC frames, large glass facades) visible from heritage precincts.

9

Principles & Process of Conservation Aspect Description International principles Charters such as the Venice Charter (1964) and Nara Document on Authenticity (1994) provide internationally recognized principles guiding conservation philosophy and practice Conservation philosophy Minimum intervention, reversibility of interventions, respect for original material/fabric/authenticity, and distinguishability of new work from original fabric Materials/techniques used Traditional (lime mortar, traditional brick/timber repair, traditional carving/joinery techniques) and modern (compatible modern consolidants, structural reinforcement where necessary) used judiciously Process — Inventory Systematic listing/documentation of heritage assets and their significance Process — Inspection Condition assessment/survey identifying decay, damage, and structural issues Process — Documentation Detailed recording (measured drawings, photographs) of the existing fabric prior to intervention Process — Degrees of intervention Ranges from preventive maintenance and consolidation to restoration, rehabilitation, and (least preferred) reconstruction, applied according to necessity and conservation philosophy

This section covers the prevailing zoning ordinances and building regulations in the Nepalese context, including Floor Area Ratio (FAR), ground coverage, setback, right of way (ROW), light plane, and prevailing area measurement systems and units.

2

Key Zoning & Building Control Parameters Parameter Description Floor Area Ratio (FAR) Ratio of total permissible built-up floor area to the total plot (land) area; governs overall building bulk/density permitted on a plot Ground coverage Percentage of the plot area that may be covered by the building footprint at ground level; the remainder must be left open (for light, ventilation, setback, parking, greenery) Setback Minimum open distance required between the building line and the plot boundary/road, ensuring light, ventilation, privacy, and space for future road widening Right of Way (ROW) The width of a road/access reserved for public passage, including carriageway and any footpath/utility strips; building setback requirements are often linked to ROW width Light plane (skyline/daylight plane) An imaginary inclined plane from a reference line (often the opposite plot boundary or road centre-line) restricting building height/massing to ensure adequate daylight/ventilation reaches neighbouring plots and streets Prevailing Area Measurement Systems and Units System/Unit Description Ropani–Aana– Paisa–Daam Traditional land measurement system used in the hill regions of Nepal (1 ropani = 16 aana = 64 paisa = 256 daam;

3

1 ropani ≈ 508.72 m²) Bigha–Kattha–Dhur Traditional land measurement system used in the Terai region (1 bigha = 20 kattha = 400 dhur;

4

1 bigha ≈ 6772.63 m²) Metric system (m², hectare) The standardized SI-derived system increasingly used in official records, drawings, and cadastral/survey documentation alongside traditional units FAR, ground coverage, setback, ROW, and light-plane provisions are typically specified in municipal building byelaws and vary by land-use zone (residential, commercial, mixed-use, industrial) and road width.

5

Building permit approval requires drawings and calculations demonstrating compliance with all applicable zoning/building control parameters before construction can proceed.

This section covers Nepalese building typologies — residential, apartment, group housing, commercial, mixed- use, institutional, and industrial — along with associated concepts of ownership, legal rights, and tenure.

2

Building Typologies Typology Description Residential Single-family or multi-family dwellings; ranges from individual detached houses to row housing Apartment Multi-unit residential building where individual units are independently owned/occupied, sharing common facilities/structure (a form of condominium ownership) Group housing Planned residential development of multiple dwelling units (often row houses or low-rise blocks) on a single larger plot, typically under unified layout/design control Commercial Buildings for trade/business use: shops, offices, markets, malls, hotels Mixed-use Buildings combining two or more use types (e.g. ground-floor commercial with upper-floor residential/office) within a single structure Institutional Buildings serving public/community institutional functions: schools, hospitals, government offices, religious institutions Industrial Buildings for manufacturing, processing, warehousing, or industrial production activities Ownership, Legal Rights & Tenure Freehold/individual ownership: outright ownership of land and building by an individual or entity, the most common tenure for independent residential/commercial buildings.

3

Condominium/apartment ownership: individual ownership of a specific unit combined with shared (undivided) ownership of common areas/facilities and land, governed by an apartment owners' association/by-laws.

4

Leasehold tenure: right to use/occupy land or building for a defined period under a lease agreement, without owning the underlying freehold title.

5

Guthi land tenure: a traditional Nepalese land tenure system where land/property is dedicated to a religious, charitable, or community trust (guthi), with proceeds supporting associated religious/cultural functions.

6

Tenancy rights: rights of a tenant occupying rented property, distinct from ownership, typically governed by a tenancy/rental agreement and relevant tenancy law.

7

Legal registration of ownership/tenure (land ownership certificate, registration at the relevant Land Revenue/Survey Office) is essential for establishing enforceable property rights in the Nepalese context.
