Guard Rail
Guard rails, guardrails, railings or protective guarding, in general, are a boundary feature and may be a means to prevent or deter access to dangerous or off-limits areas while allowing light and visibility in a greater way than a fence. Common shapes are flat, rounded edge, and tubular in horizontal railings, whereas tetraform spear-headed or ball-finialled are most common in vertical railings around homes. Park and garden railings commonly in metalworking feature swirls, leaves, plate metal areas and/or Motif (visual arts), motifs particularly on and beside gates. High security railings (particularly if in flat metal then a type of palisade) may instead feature jagged points and most metals are well-suited to anti-climb paint. A handrail is less restrictive on its own than a guard rail and provides support. Public safety Many public spaces are fitted with guard rails as a means of protection against accidental falls.

Building
A building or edifice is an enclosed Structure#Load-bearing, structure with a roof, walls and window, windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, monument, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the :Human habitats, human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much architecture, artistic expression. ...

Observation Tower
An observation tower is a tower used to view events from a long distance and to create a full 360 degree range of vision to conduct long distance observations. Observation towers are usually at least tall and are made from stone, iron, and wood. Many modern towers are also used as TV towers, restaurants, or churches. The towers first appeared in the ancient world, as long ago as the Babylonian Empire. Observation towers that are used as guard posts or observation posts over an extended period to overlook an area are commonly called watchtowers instead. Similar instances of observation towers are recognised as Crow's nest, crow's nests, Observatory, observatories, Viewing platform, viewing platforms, etc. Construction and usage Observation towers are an easily visible sight on the countryside, as they must rise over trees and other obstacles to ensure clear vision. Older control rooms have often been likened to medieval chambers. The heavy use of stone, iron, and wood in their ...

Alvar Aalto
Hugo Alvar Henrik Aalto (; 3 February 1898 – 11 May 1976) was a Finnish architect and designer. His work includes architecture, furniture, textiles and glassware, as well as sculptures and paintings. He never regarded himself as an artist, seeing painting and sculpture as "branches of the tree whose trunk is architecture." Aalto's early career ran in parallel with the rapid economic growth and industrialization of Finland during the first half of the 20th century. Many of his clients were industrialists, among them the Ahlström-Gullichsen family, who became his patrons. The span of his career, from the 1920s to the 1970s, is reflected in the styles of his work, ranging from Nordic Classicism of the early work, to a rational International Style (architecture), International Style Modernism during the 1930s to a more organic modernist style from the 1940s onwards. His architectural work, throughout his entire career, is characterized by a concern for design as Gesamtkunstwerk— ...

International Building Code
The International Code Council (ICC), also known as the Code Council, is an American nonprofit standards organization sponsored by the building trades, which was founded in 1994 through the merger of three regional model code organizations in the American construction industry. Since 2023, ICC's headquarters has been based at Capitol Crossing in Washington, D.C. The organization creates the International Building Code (IBC) and International Residential Code (IRC), two model building codes, which have been adopted for use as a base code standard by most jurisdictions in the United States. The ICC's model codes have been criticized for inflating housing costs and reducing housing supply in the United States through arbitrary and stringent standards that do little for safety and are out of sync with best practices in other countries. The IBC has contributed to the spread of 5-over-1 type of buildings across the US and contributed to a lack of medium-density housing (so-called ...

Ironwork
Ironwork is any weapon, artwork, utensil, or architectural feature made of iron, especially one used for decoration. There are two main types of ironwork: wrought iron and cast iron. While the use of iron dates as far back as 4000 BC, it was the Hittites who first knew how to extract it (see iron ore) and develop weapons. Use of iron was mainly utilitarian until the Middle Ages; it became widely used for decoration in the period between the 16th and 19th century. Wrought iron Wrought ironwork is forged by a blacksmith using an anvil. The earliest known ironwork are beads from Jirzah in Egypt dating from 3500 BC and made from meteoric iron with the earliest use of smelted iron dates back to Mesopotamia. However, the first use of conventional smelting and purification techniques that modern society labels as true iron-working dates back to the Hittites in around 2000 BC. Knowledge about the use of iron spread from the Middle East to Greece and the Aegean region by 1000 BC and ...

Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.05%) in contrast to that of cast iron (2.1% to 4.5%), or 0.25 for low carbon "mild" steel. Wrought iron is manufactured by heating and melting high carbon cast iron in an open charcoal or coke hearth or furnace in a process known as puddling. The high temperatures cause the excess carbon to oxidise, the iron being stirred or puddled during the process in order to achieve this. As the carbon content reduces, the melting point of the iron increases, ultimately to a level which is higher than can be achieved by the hearth, hence the wrought iron is never fully molten and many impurities remain. The primary advantage of wrought iron over cast iron is its malleability - where cast iron is too brittle to bend or shape without breaking, wrought iron is highly malleable, and much easier to bend. Wrought iron is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it ...

Balcony
A balcony (from , "scaffold") is a platform projecting from the wall of a building, supported by columns or console brackets, and enclosed with a balustrade, usually above the ground floor. They are commonly found on multi-level houses, apartments and cruise ships. Types The traditional Maltese balcony is a wooden, closed balcony projecting from a wall. In contrast, a Juliet balcony does not protrude out of the building. It is usually part of an upper floor, with a balustrade only at the front, resembling a small loggia. A modern Juliet balcony often involves a metal barrier placed in front of a high window that can be opened. In the UK, the technical name for one of these was officially changed in August 2020 to a ''Juliet guarding''. Juliet balconies are named after William Shakespeare's Juliet who, in traditional staging of the play ''Romeo and Juliet'', is courted by Romeo while she is on her balcony—although the play itself, as written, makes no mention of a balcony, ...
