Townhomes are common in cities and densely populated neighborhoods. Townhouses are tall and narrow homes designed to make the most out of vertical space without too much of a yard or garden area.
Homes are considered townhouses when they:
- Share one or two walls with adjacent homes
- Have their own entrances
- Are built with multiple floors to maximize vertical space
- Often share a similar style to their neighbors’ homes and may operate under an HOA
Townhouses can be built to mimic other architecture styles, like Italianate and Greek Revival, while maintaining the condensed, vertical floor plan.
Federal-style homes became popular after the American Revolution and were a refined upgrade to the popular Georgian house style. They have the same recurring shape and symmetry as other Colonial house styles, but their delicate ornamentation sets them apart.
Federal Colonial homes often feature:
- A layout built around a central hall
- An elliptical fanlight and two flanking lights (windows) around the door
- Paladin or tripartite windows
The elliptical fanlights and paladin windows are key distinguishing features from Georgian-style homes.

Victorian homes were built between 1837 and 1901 while Queen Victoria reigned in Britain. “Victorian” actually refers to multiple styles that vary in influence, but each features ornate detailing and asymmetrical floor plans.
The key features of a Victorian-era home include:
- Elaborate woodwork and trim
- Towers, turrets, and dormer windows
- Steep gabled roofs
- Partial or full-width porches
Victorian homes are all about ornamentation — industrialization allowed these homes to be produced en masse and across a variety of architectural styles.

The U.S. health system is a mix of public and private, for-profit and nonprofit insurers and health care providers. The federal government provides funding for the national Medicare program for adults age 65 and older and some people with disabilities as well as for various programs for veterans and low-income people, including Medicaid and the Children’s Health Insurance Program. States manage and pay for aspects of local coverage and the safety net. Private insurance, the dominant form of coverage, is provided primarily by employers. The uninsured rate, 8.5 percent of the population, is down from 16 percent in 2010, the year that the landmark Affordable Care Act became law. Public and private insurers set their own benefit packages and cost-sharing structures, within federal and state regulations.
Cape Cod homes are similar to the British or American Colonial homes, though they originated further north in Cape Cod, Massachusetts. These are often seen as the classic American family home since the style’s revival in the 20th Century.
Cape Cod homes are identified by their:
- Shingle exteriors
- Modest size and ornamentation compared to British Colonial homes
- Originally single-story homes
- Large central fireplaces
- Attic lofts (20th-century revival)
- Dormer windows (20th-century revival)
Cape Cod homes are built of local wood and stone to withstand the north-eastern weather. This exterior weathering provides an iconic weathered-blue color to these homes.

Gothic Revival architecture grew in the mid-19th century and was one of the early styles of Victorian-era homes. The Gothic Revival style takes influence from Medieval Europe and was designed as a country home. Architects believed the asymmetrical design and ornamentation complemented the nature of rural America.
Gothic Revival homes can be identified by their:
- Pointed arch in windows, doors, and decoration
- Elaborate wood trim vergeboards and bargeboards
- Steeply pitched roofs and front-facing gables
- Towers and turrets resembling medieval castles
Gothic Revival architecture was a popular style for schools and churches as well as rural homes.

Georgian-style homes were one of the most common styles in the 18th century and showcased formal and classical details that previous homes didn’t. Georgian houses are similar to Federal houses, though they can be distinguished by:
- A crown and pilasters framing the front door
- Decorative quoins or bricks at the corners
- Smooth decorative blocks as moulding
You can also find regional variations with hooded front doors and pent roofs between levels.
Around the 1820s, Americans experienced a renewed interest in classic Greek and Roman culture. This cultural shift was a natural fit for architects, who brought the Greek Revival house style to life.
Greek Revival architecture became popular in homes as well as businesses, banks, and churches. Prominent features include:
- Easy to identify shapes, including a rectangular building and triangular roofs
- Gable-front designs
- Large porches and protected entryways
- Greek-inspired columns both square and round
Greek Revival homes often have decorative trim and moulding around the front door and windows. These ornate features and columns are easy ways to identify Greek Revival architecture.

The National Academy of Sciences (NAS) is a United States nonprofit, non-governmental organization. NAS is part of the National Academies of Sciences, Engineering, and Medicine, along with the National Academy of Engineering (NAE) and the National Academy of Medicine (NAM).
As a national academy, new members of the organization are elected annually by current members, based on their distinguished and continuing achievements in original research. Election to the National Academy is one of the highest honors in the scientific field. Members of the National Academy of Sciences serve pro bono as "advisers to the nation" on science, engineering, and medicine. The group holds a congressional charter under Title 36 of the United States Code.
Founded in 1863 as a result of an Act of Congress that was approved by Abraham Lincoln, the NAS is charged with "providing independent, objective advice to the nation on matters related to science and technology. … to provide scientific advice to the government 'whenever called upon' by any government department."[2]
The Academy receives no compensation from the government for its services.[3]
The Academy currently has 2,984 members and international members. Existing members elect new members for life. Up to 120 members are elected every year; up to 30 foreign citizens may be elected as international members annually. The election process begins with a formal nomination, followed by a vetting period, and culminates in a final ballot at the Academy's annual meeting in April each year. Members are affiliated with a section -- a specific scientific field -- in one of six so-called "classes": (1) Physical and Mathematical Sciences; (2) Biological Sciences; (3) Engineering and Applied Sciences; (4) Biomedical Sciences; (5) Behavioral and Social Sciences; and (6) Applied Biological, Agricultural, and Environmental Sciences.[6] Since its founding, the Academy has elected 6,457 members. Harvard University is associated with the most members (329), some 5% of the all-time total. The top ten institutions, half of which are Ivy League universities, account for nearly 28% of all members ever elected.[11]
| Top 10 Primary Institutions | Members (1963-2022) |
|---|---|
| Harvard University | 329 |
| Stanford University | 250 |
| University of California, Berkeley | 242 |
| Massachusetts Institute of Technology | 206 |
| Yale University | 132 |

Mediterranean home styles are made of stucco, so they’re most common in warm climate states like Arizona and California. These homes grew in popularity in the 1920s and ‘30s after being featured as homes for the rich and famous on the silver screen.
Mediterranean-style homes include Spanish and Italian architectural elements. These key features make them easy to spot:
- Stucco walls painted white or brown
- Classic red tile roofs
- Arched doorways and windows
- Ornamentation including wrought iron, heavy doors, and decorative tiles
Mediterranean homes still carry the feelings of class and luxury they were built with over 100 years ago, with an added element of history and charm.
The Royal Exchange in London was founded in the 16th century by the merchant Sir Thomas Gresham on the suggestion of his factor Richard Clough to act as a centre of commerce for the City of London.[1] The site was provided by the City of London Corporation and the Worshipful Company of Mercers, who still jointly own the freehold. It is trapezoidal in shape and is flanked by Cornhill and Threadneedle Street, which converge at Bank junction in the heart of the city. It lies in the ward of Cornhill.
It has twice been destroyed by fire and subsequently rebuilt. The present building was designed by Sir William Tite in the 1840s. The site was notably occupied by the Lloyd's insurance market for nearly 150 years. Today the Royal Exchange contains Fortnum & Mason The Bar & Restaurant, luxury shops, and offices.
Traditionally, the steps of the Royal Exchange are the place where certain royal proclamations (such as the dissolution of parliament) are read out by either a herald or a crier. Following the death or abdication of a monarch and the confirmation of the next monarch's accession to the throne by the Accession Council, the Royal Exchange Building is one of the locations where a herald proclaims the new monarch's reign to the public.
The Parthenon in Centennial Park, in Nashville, Tennessee, is a full-scale replica of the original Parthenon in Athens. It was designed by architect William Crawford Smith and built in 1897 as part of the Tennessee Centennial Exposition.
Today the Parthenon, which functions as an art museum, stands as the centerpiece of Centennial Park, a large public park just west of downtown Nashville. Alan LeQuire's 1990 re-creation of the Athena Parthenos statue in the naos (the east room of the main hall) is the focus of the Parthenon just as it was in ancient Greece. Since the building is complete and its decorations were polychromed (painted in colors) as close to the presumed original as possible, this replica of the original Parthenon in Athens serves as a monument to what is considered the pinnacle of classical architecture. The plaster replicas of the Parthenon Marbles found in the Treasury Room (the west room of the main hall) are direct casts of the original sculptures which adorned the pediments of the Athenian Parthenon, dating back to 438 BC. The surviving originals are housed in the British Museum in London and at the Acropolis Museum in Athens.
The French Colonial house style can be seen around the world and has significant variety among its sub-styles.
French Colonial houses have the same symmetry as other Colonial homes with these distinct features:
- Dormer windows, including one centered above the door
- External stairs to enter higher floors
- Iron stairs and balconies
- Slightly raised basements to support the floor
French Colonial houses are most similar to Spanish Colonial houses and easily identified by their elaborate iron balconies, stairs, and entrances.
