The Building Act 1774 (formally known as the Fires Prevention (Metropolis) Act 1774) was an
The 1774 Act standardised the quality and construction of buildings and made the exterior of a building as fire-proof as possible, by restricting any superfluous exterior timber ornamentation except for door frames and shop fronts. The Act placed buildings into classes or "rates" defined by size and value, with a code of structural requirements for the
Professor Sir John Summerson, one of the leading British architectural historians of the 20th century, described it as "the great Building Act of 1774, a milestone in the history of London 'improvement'".[1] It was the leading reason for the appearance of the many Georgian houses, terraces and squares which remain important features of some parts of London and other cities and towns within the United Kingdom, the Republic of Ireland and elsewhere.[2]
Background
After the Great Fire of London of 1666, it was realised how much the traditional construction of buildings had aided the spread of the fire, with the close proximity of buildings and the incendiary nature of building material such as timber and thatch fuelling the fire.[3] Several Acts of Parliament over the next century attempted to improve building regulations:
- 18 & 19 Cha. 2. c. 8), also known as the London Building Act, determined that street widths, as well as the heights of houses, were regulated and brick construction was prescribed. Timber-framed buildings were forbidden. There could be no projections or jetties over the streets, because they allowed fire to leap from house to house. The intention was to make the street into an effective firebreak
- Mischiefs by Fire Act 1707 (6 Ann.c. 31) stipulated that wooden roofs had to be surrounded by a stone parapet
- Mischiefs by Fire Act 1708 (7 Ann.c. 17), also known as the London Building Act 1708, stipulated that window wooden frames should no longer be flush with the walls, but recessed
- Mischiefs by Fire Act 1724 (11 Geo. 1. c. 28)
- London Streets, City Act 1759 (33 Geo. 2. c. 30)
- Better Regulating of Buildings etc. Act 1764 (4 Geo. 3. c. 14)
- London Widening of Passages, etc. Act 1766 (6 Geo. 3. c. 27)
- Metropolitan Buildings Act 1772 (12 Geo. 3. c. 73), relating to party wall construction
These previous Acts had mostly failed due to the lack of enforcement.[4] The Building Act 1774 replaced, consolidated, improved and enforced these previous Acts.[5]
The new Act was drafted by the architects Robert Taylor and George Dance the Younger, who was then Clerk of the City Works.[Note 1] Its aims included:[1]
- Making the exterior of ordinary houses as nearly incombustible as possible
- Preventing slipshod construction of party walls
- Preventing disputes between adjoining owners of party walls
The Bill was submitted to the House of Commons in February 1774 by Robert Taylor and James Adam as "Joint Architects to H. M. Works", "on behalf of the Builders of London and Westminster", who found the existing legislation confusing and out of date.[6]
Title, short title and popular names
Acts passed by the Parliament of Great Britain did not originally have
"An act for the further and better regulation of buildings and party-walls; and for the more effectually preventing mischiefs by fire within the cities of London and Westminster, and the liberties thereof, and other the parishes, precincts, and places, within the weekly bills of mortality, the parishes of Saint Mary-le-bon, Paddington, Saint Pancras, and Saint Luke at Chelsea, in the county of Middlesex; and for indemnifying, under certain conditions, builders and other persons against the penalties to which they are or may be liable for erecting buildings within the limits aforesaid contrary to law."
The
Main provisions
Building rates
In order to lay down hard and fast, standardised rules of construction it was necessary to categorise London buildings into separate classes or "rates". Each rate had to conform to its own structural code for foundations, thicknesses of external and party walls, and the positions of windows in outside walls. For all rates, the 1774 Act stipulated that all external window joinery was hidden behind the outer skin of masonry, as a precaution against fire. It also regulated the construction of hearths and chimneys.
The Act determined seven types of building construction graded by ground area occupied and value.[Note 2][11][12] The four rates applicable to houses predicted the likely social class of their occupants.[13]
- A 'First Rate' house was valued at over £850, and occupied an area on the ground plan of more than nine "squares of building" (900 square feet (84 m2)). These houses were typically for the "nobility" or "gentry". The occupants would frequently not own the house, but would rent and use it as their townhouse[14] as a temporary alternative to their larger country house.
- A 'Second Rate' house was valued at between £300 and £850, and occupied an area on the ground plan of between five and nine "squares of building" (500–900 square feet (46–84 m2)). These houses were typically for "merchants", and might face notable streets or the River Thames.
- A 'Third Rate' house was smaller and valued at between £150 and £300, and occupied an area on the ground plan of between three and a half and five "squares of building" (350–500 square feet (33–46 m2)). These houses were typically for "clerks", and faced principal streets.
- A “Fourth Rate” House was valued at less than £150, and occupied an area on the ground plan of less than three-and-a-half "squares of building" (350 square feet (33 m2)). These houses were typically for "artisans", and would be found in minor streets.
All external woodwork, including ornament, was banished, except where it was necessary for shopfronts and doorcases. Bowed shop windows were made to draw in to a 10 inches (250 mm) or less projection. Window joinery which previous legislation had already pushed back from the wall face was now concealed in recesses to avoid the spread of fire.

Disputes
The Act regulated the responsibilities of the owners of party walls, and defined how disputes would be resolved.
Responsibilities of Surveyors
To address the past difficulties with enforcement, the Act created a statutory role for the surveyor. He had to survey any new building or wall being built, and was paid a fee by the master workman constructing the work. The surveyor had to swear an oath that he would ensure the rules and regulations of the Act were observed.[7] This led in 1844 to the role of "district surveyor".[15]
Parish Duties

The Act stated that every
Insurance and accident
Before 1774 liability for fires in England was strict without exception. No excuse was permitted when an owner allowed a fire to spread to neighbouring properties, due to the danger of fire in crowded and largely wooden mediaeval towns and villages. The Act relaxed this liability by stipulating that no action should be taken against someone who caused a fire by accident. The Act also included measures to prevent deliberate fire setting in order to claim insurance
Adoption of the Act, and demand for the Third Rate House

During the half-century or so after the 1774 Act came into force, building in brick or stone became standard in cities and towns, and houses of the second, third and fourth rate became standardised throughout the country.[18]
The rising population in London generated demand for housing, encouraging land owners to develop large tracts of land. The great majority of these developments were built speculatively: land owners improved their land by laying out roads and services, and then granted building leases on this land. Housing developers (landlords) would build "spec" houses on the improved land and generate an income from leaseholders by collecting rent.[19] A builder-speculator bought the leasehold of a site from the ground landlord and built the shell and roofed and floored it, usually with the bare internal walls roughly plastered out. This would be in accordance with the stipulations laid down by the 1774 Act and with the guidance of pattern books such as Peter Nicholson's The New Practical Builder (1823).[20] The first true occupiers of the house would then have the carcass finished to their own taste. Builders' guides were published, simplifying the statutory requirements.[21][22]
In 1821 the population of London had been 1.38 million. In the next fifty years it grew by a further million and the resultant need for housing, coming mainly from lower-middle and middle-class families – clerks, shopkeepers and other such tradespeople – was best met through the provision of terraced houses of medium size.[23] By far the greatest number of speculative houses built were of the third rate, whose exact dimensions were arrived at as a result of the areas defined in the Act. Also, J.C. Loudon suggested in The Suburban Gardener and Villa Companion (1838), "this technical classification of houses has been made by the British legislature, chiefly with a view to facilitate their assessment for taxes",[24] referring to taxes on windows,[Note 3] glass[Note 4] and brick,[Note 5] and houses were built to suit. Demand for the third rate house placed it at the forefront of the housing market; intended to offer the speculative builder the greatest economy, and the middle-class house buyer the greatest value, the terraced third rate house became, according to Loudon, the most numerous house type in early nineteenth-century London.[25]
Outside of London
Many of the regulations of the Act were subsequently applied outside of London in other cities and towns of
Criticism of the Act

In Georgian London (1945), Summerson described how "the Act contributed largely to what the later Georgians and early Victorians conceived to be the inexpressible monotony of the typical London street, a monotony which certainly must, at one time, have been overpowering."[31] Whole streets and even neighbourhoods consisted of the same size of house. Ornament was discouraged, most woodwork was forbidden other than doors; window joinery was concealed behind recesses in the wallface. Summerson himself referred to a Georgian terrace, built in Dublin under the standards of the Act, as "simply one damned house after another".[32]
Victorians found the resulting houses and streets monotonous and the dimensional restraints tyrannical, and christened the Act "The Black Act of 1774",[33] although it was more likely the increasingly efficient capitalisation of building, not legislation, that was the main cause of this.[34] Benjamin Disraeli blamed the Act for "all those flat, dull spiritless streets all resembling each other, like a large family of plain children."[35] He also observed in his novel Tancred; or, the New Crusade (1847)[36] that:
"Though London is vast, it is very monotonous. All those new districts that have sprung up within the last half-century, the creatures of our commercial and colonial wealth, it is impossible to conceive anything more tame, more insipid, more uniform. Pancras is like Mary-le-bone, Mary-le-bone is like Paddington; all the streets resemble each other, you must read the names of the squares before you venture to knock at a door."
Gower Street in Bloomsbury, for example, was described by The Builder journal in 1887 as "one of the dullest, gloomiest thoroughfares in town [with its] monotonous elevations wholly unbroken or unrelieved",[37] and was referred to a decade later by historian Sir Laurence Gomme, in his commentary on London in the Reign of Victoria, as a "hideous monstrosity".[38]
The Victorians often did their best to destroy the scale and symmetry which were the hallmark of the Act, by breaking up the line of Georgian frontages and adorning their immaculate façades with terracotta and composition dressings.[39]
Apart from the rigid building prescriptions, the Act made no controls which related to matters of health. There were no controls on the amount of open space related to a dwelling, on the width of streets, on the height of buildings or on the height of rooms – even though these last two matters had had some tentative control under the earlier Rebuilding of London Act 1666. The 1774 Act did not legislate any limit on occupancy. Smaller houses which yielded low rents were increasingly shoddily built, and the combination of overcrowding and poor-quality housing led to a severe decline in general living conditions. The provisions were lacking in detail, especially in the areas of drainage and sanitary facilities, ventilation and damp proofing.[40]
Partial repeal
The 1774 Act was largely replaced by the
Importance of the Act

As well as facilitating the enforcement of a structural code, the importance of the Building Act 1774 as explained by Summerson[44] was that:
"it confirmed a degree of standardisation in speculative building. This was inevitable; for the limitation of size and value set out in the rating tended to create optimum types from which there was no escape and within which very little variation was possible. Especially did the second, third and fourth rates of houses tend to become stereotyped. This was, in many ways, an excellent thing: it gave some degree of order and dignity to the later suburbs and incidentally laid down minimum standards for working-class urban housing which would have been decent if they had been accompanied by legislation against overcrowding."
The Act moved London away from its earlier chaotic and often mediaeval conditions, and ensured that whole city would be decent, handsome and orderly. It meant that, in an era when almost all construction was undertaken on speculative building leases, the landowner, the tenant and the community at large had a real guarantee of quality.[45]
Despite the later criticisms, it had a greater effect upon London than any other previous legislative measure, and had major influence in other cities and towns. It has been suggested that, by imposing a uniform image and a means to identify and control London before its subsequent immense expansion, the Act prepared the capital for its next imperial phase.[46]
The Act established over its long career a machinery for control which was well tried and tested. It established the origins of the role of District Surveyor[Note 6] and above all it acted as a model for subsequent regulations. It showed how a town or city council could obtain and administer legislation that would control the construction of buildings within a city in the interests of public safety and health.[40] The Building Acts in Bristol[Note 7][Note 8] were closely modelled on it and there were certain similarities in the Acts[Note 9] in Liverpool.[47] It established the principle that every parish had a duty to maintain equipment for fire fighting and rescue.
The new rating system led to the development of what are today perceived as grand and gorgeous terraces and squares in London and other cities and towns, creating simple and elegant uniformity which is much admired and reflected in the premiums paid when purchasing a Georgian property.[48] Most are now protected with listed building status.

Notes
- ^ Some works describe fellow architect and "improver" John Gwynn as a key figure in the introduction of the 1774 Act, but the source of this claim is elusive.
- ^ The Act simply specifies an undefined house "value". The Bank of England's Inflation Calculator gives the equivalence in prices between 1774 and 2020 as: £850 equivalent to £131,059; £300 equivalent to £46,256; £150 equivalent to £23,128. The landowner would normally grant a building licence to a builder and make an annual charge according to the location and the length of the frontage. According to the London County Council's Survey of London description of Ground Rent (referenced below), the cost per foot typically varied between a few shillings and a few guineas. The cost per foot was then multiplied by the total square footage of the footprint of the dwelling to set the ground rent and the house “rate”.
