Built Heritage and Conservation Revision Notes for Leaving Cert Construction Studies

Vernacular and Georgian Architecture

Vernacular architecture, also called local or native architecture, is an informal style of building that responds to the needs of local people.
It uses materials available in the local area and follows traditional construction methods.
The design is influenced by climate, terrain, culture, and the skills of the builder.
Styles vary from place to place and even within the same country.

Local needs – Buildings are designed to suit the lifestyle and requirements of the community.
Local materials – Structures are made using resources available in the area (e.g. stone, mud, turf, timber, reeds, straw, ice, animal skins).
Local traditions – Construction methods follow established regional techniques.

Usually modest in scale, enough to house occupants.
Simple design and limited range of materials.
Not standardised – design depends on available materials, local climate, terrain, and builder's skill.
Environmentally sustainable – materials do not need long-distance transport and are often waste products or naturally abundant.
Harmonise with the local landscape.

Tipi – Timber frame covered with animal skins. Mobile structure for nomadic Native Americans of the Great Plains.
Igloo – Ice-block structure for Inuit people, providing insulation in freezing conditions.
Irish thatched cottage – Built from clay, mud, stone, or turf. Roof thatched with reeds, sedges, or straw from crops. Symbol of Irish rural heritage.

Traditional west coast dwellings were modest and simple.
Most had one main room, used by the family for cooking, eating, and sleeping.
In bad weather, animals were often brought inside, with the lower part of the house used for shelter.
Houses were often built on a slope. Wealthier families sometimes had a separate byre attached to the house.
Walls were built using stone with lime mortar, or sometimes mud or peat. Exteriors were usually limewashed white.
Interiors were sparsely furnished, with storage often provided by recesses built into the walls.
Many had a loft for extra sleeping space.
Roofs were usually thatched, but slate was sometimes used in wealthier homes, especially along the coast.
The gable end of the house was built facing the prevailing wind for protection.
These dwellings were most common in Munster and Connacht, with some examples in Ulster.

East coast homes were generally more elaborate because of the milder climate, better farmland, and greater wealth in the region.
Houses had more rooms, and some had full lofts above the ground floor.
Wealthier homes were lime-rendered both inside and out.
Walls were built from stone and coated with lime render to allow moisture to evaporate, preventing condensation and mould.
Roofs were often half-hipped or hipped.
East coast dwellings often had separate living and sleeping spaces, unlike the single-room layouts of the west.
The living space was usually arranged around a central hearth.
These houses were most common in Leinster and parts of Ulster.
Interiors were better furnished, reflecting the greater wealth of the owners.

Lime render has been used for over 10,000 years as a protective and breathable wall finish.
It is made from a mix of lime, sand, and water.
The traditional ratio is one part lime to 2.5–3 parts sand.
Coarse sand is preferred to reduce cracking.
Lime render allows moisture to pass through walls, controlling humidity and preventing condensation and mould.

Over time, many cottages were extended or given a second storey, often with the help of grants.
These improved homes were sometimes called "thatch mansions."
Thatch was sometimes replaced with slate on the main dwelling.
Corrugated iron was often used for the roofs of surrounding outbuildings.

Time Period: Arrived in Ireland around the turn of the 18th century.
Who Built Them: Rich landlords who extended their homes or built new dwellings to add to their estates.
Design:
- Simple, usually two storeys high.
- Visitors entered into a hallway, with all rooms accessible from it (unlike the standard cottage where entry was into the kitchen).
Features:
- Wooden panelled doors with fanlights above.
- Sliding sash windows, three bays across.
- Rendered walls, sometimes painted.
- Roofs were slated and sometimes hipped.
Key Principle:
- Proportion was essential.
- All elements - windows, doors, heights - were built to set ratios for aesthetic balance.
Influence:
- Inspired by Palladian architecture, based on the work of Italian architect Andrea Palladio.
- Followed symmetry, perspective, and principles of ancient Roman architecture.
Irish Examples:
- Bessborough House, Co. Kilkenny.
- Leinster House, Dublin.

Where Found:
- Common in cities like Dublin (Merrion Square), Limerick (Pery Square), and other urban areas.
- Houses were often arranged around squares or in terraces.
Design:
- Four storeys high over a basement.
- Reception rooms located on the first floor.
- In midlands and east, façades often clad in brick.
Windows:
- Sash windows with multiple glass panels, giving height and proportion to the façade.
- Upper storey windows were shorter to maintain proportion when viewed from the street.
Doors:
- Doors were focal points, often with pillars or windows beside them.
- Half-circular fanlights were common above doors.
- Decorative steps and iron railings often led up to the entrance.
Materials:
- In Dublin, brick was often surplus ship ballast from England.
- In other regions, buildings followed the Georgian style but used local materials instead of brick.
Overall Look:
- Elegant, symmetrical façades.
- Simple front elevation with windows and doors as the main decorative features.
