Maps are key documentary sources for researching buildings and houses. This page highlights how the Library's map collections can shed light on a building’s history as well as the area that surrounds it. All the resources on this page are freely available on the National Library of Scotland’s website. Thoughout this page, we will relate back to a case study to illustrate the uses of the various maps and map series. The case study is a tenement building in Leith, on Constitution Street.


This page will take you through the most relevant maps for researching building and house history, arranged roughly chronologically:

To use our map collections, you can search for digitised maps on our website, watch help videos, contact us or ask a question. You can also visit us by making an appointment to visit our Maps Reading Room in Edinburgh.

County and Estate Maps

The earliest regional or county maps of Scotland, surveyed by Timothy Pont in the late 16th century, often illustrate larger castles and tower houses, churches, mills, and other significant buildings. Further information on Pont’s depiction of towns. Blaeu’s maps, published in 1654, mostly based on Pont’s work, cover nearly all of Scotland, and are useful for showing and naming significant buildings in the rural landscape.

County maps published in the 18th and 19th centuries often provide good detail of rural buildings, including country mansions, farms, and the general pattern of buildings in settlements. You can sometimes find quite detailed depictions of larger houses and estate houses. In 1832, John Thomson's Atlas of Scotland was published, which included 58 detailed county maps, of every county in Scotland.

Estate mapping similarly often provides the earliest detailed depictions of rural housing. The functions or occupants of buildings are sometimes named in estate plans, including the gardener’s house, barn, mill, and ‘Pigeon House’ or dovecote/doocot.

Estate maps were associated with landscape improvement, and were often funded by landowners to plan and implement agricultural change. Parts of the Lowlands and Borders have the earliest estate maps in the mid-18th century, whilst some parts of the Highlands or the Nothern and Western Isles have their earliest estate maps in the first half of the 19th century. Reorganisation and consolidation of rural housing was a key part of the agricultural transformation, as was the development of planned villages and crofts. Estate maps often show the earliest houses in these settlements.

Town Plans

Alexander Wood's Plan of the Town of Leith (1777)
Alexander Wood's Plan of the Town of Leith (1777) is the earliest map clearly showing Constitution Road in Leith, before it was renamed as Constitution Street in the 1780s, and extended to meet with Kirkgate and the foot of Leith Walk.

Town plans include some of the earliest and some of the most detailed maps in our collections. The size of the maps and the level of detail on town plans made it increasingly possible for these maps to show individual buildings and document their changes over time. Several even include the names of building and property owners, in addition to portraying the layout of streets and gardens. Before the Ordnance Survey mapping of the mid-19th century, these plans were usually the most detailed maps published of towns showing buildings. From the 1840s, Ordnance Survey maps may provide more detail, but other town plans by private individuals or companies were often published more regularly (for example, Post Office Directories) and show different features, so are also useful to consult.

Kirkwood's plan of the City of Edinburgh and its environs (1817)
Robert Kirkwood's Plan of the City of Edinburgh and its environs (1817) shows planned developments for Leith in pink, north of the river, as well as proposed routes for the Union Canal. In fact, the Union Canal never reached Leith, and only some of these roads were built.

Town plans, as for other maps, are never a simple facsimile of the townscape. Often, mapmakers chose to only include buildings above a certain size, and ignore those that were small or considered "temporary". Many town plans were not based on an original survey, but copied from earlier maps, and their creators may not have included updated building details to reflect what was there on the ground. In other cases, map-makers may have shown anticipated or planned developments, but did not always clearly distinguish these planned developments from buildings already there. It is always useful to consider who made the town plan, their sources of information, their purpose and their intended audiences, as well as other written sources (if available), to assess how far to trust details shown on the plans.

John Wood's Town Plans

Lothian's Plan of the Town of Leith and its vicinity (1822)
Lothian's Plan of the Town of Leith and its vicinity (1822) is one of the earliest maps which clearly shows our case study building.

John Wood's Town Plans are clear, large-scale plans of over fifty towns in Scotland, most of them surveyed between 1818 and 1826. For several smaller towns, these are the earliest detailed town plans. These are useful if your property is central in one of the towns that was mapped. Wood's Descriptive account of the principal towns in Scotland (1828), accompanied his Town Atlas of Scotland published in the same year, and contains informative descriptions of the 48 Scottish towns included in the Town Atlas.

John Wood (c.1780–1847) was the most significant surveyor of British towns in the early nineteenth century, drawing maps of at least 148 towns in Britain between 1818 and 1846. In a few cases, Wood's plans are based on the work of earlier map makers, who are usually clearly credited in the map title, but more often he undertook his own original survey. In some cases too, Wood's maps also include the names of proprietors of houses - for example, John Wood's Plan of Dalkeith (1822).

Great Reform Act, 1832 - plans and reports

Detailed maps and reports of 75 towns in Scotland were created for the purposes of implementing the Great Reform Act (Scotland), 1832. These are not as detailed as Wood’s plans in terms of individual houses/buildings, but they have valuable accompanying written textual reports on each town. The reports include information such as number of houses in the town, population, and qualitative information about the town.

Goad Fire Insurance Plans

The Charles Goad Fire Insurance Plans of Scottish Towns were surveyed from the 1880s-1940s. They provide detailed information used to assess the fire risk of urban buildings. They are particularly useful for showing the function of each building, and often the names of particular companies or institutions there. They are very detailed, and are most useful for building history of commercial buildings. Unfortunately these plans only cover Edinburgh, Leith, Glasgow, Dundee, Paisley, Greenock, and Campbeltown.

Unlike Ordnance Survey maps, Goad plans are useful for including underground features such as basements and cellars in buildings. They also include the number of windows in rooms, distinguish wooden walls (in yellow) from those built of brick or stone (in red), and at the top of the building show detail such as skylights or glass roofs.

Post Office Directory maps

Post Office Directories and their maps are uniquely useful urban history sources from the late 18th through to the mid 20th centuries. Over time, particularly from the 1830s, Post Office Directories included an alphabetical list of personal names and addresses; a list by ordered street and house number; and a commercial trade listing, often with useful supplementary information and advertisements. Edinburgh and Glasgow's Directories were first published from the late 18th century; those for Aberdeen, Dundee, and Perth from the 1820s-1840s. Directories for many smaller towns were first published in the later 19th century.

Street maps were increasingly regarded as an essential component in the Directories as time went by. These maps were often at a scale of Six-Inches to the Mile (1:10,560), a scale that allowed streets and building blocks to be seen, but not individual buildings. However, as the Directory companies funded the compilation of revised new maps on an annual basis, Post Office Directory maps can show specific road and building updates between years, in contrast to Ordnance Survey maps, which were only revised at intervals of 10 to 30 years or longer.

Military Maps

Roy Military Survey, focused on Leith
Roy Military Survey, focused on Leith (1752-55). You can observe how built up Leith was in the mid-18th century.

These are maps and plans that were created for military purposes, such as troop movements, battle layouts, or military infrastructure. More information on military mapping (18th-19th centuries).

The Roy Military Survey (1747-1755) covered all of mainland Scotland, clearly showing built structures such as houses in red. While the numbers of red dots do not accurately show the number of real buildings on the ground, their overall patterns and arrangements often do usefully reflect the mid-18th century landscape. Although William Roy described the map as a 'magnificent military sketch, [rather] than a very accurate map of the country', features of interest to an army commander, including farms, villages and hamlets, are often remarkably accurate.

The Roy Military Survey, and other military mapping, can sometimes be the earliest mapping we have of more rural areas showing buildings.

The earliest detailed maps of several towns in Scotland, including Fort William, Inverness, Perth, Stirling were made for military purposes. Sometimes plans made to assist with the construction of military roads (1720s-1760s) show houses, farms and related buildings along the route of the road.

Ordnance Survey Maps

Timeline of OS mapping:

Ordnance Survey had a specific responsibility to show public buildings distinctively and/or name them. In 1888, "public buildings" were definted as: almshouse, assembly room, asylum, athenaeum, auction mart, aquarium, bank, barrack, bath, bridewell, cathedral, church, chapel, club, college, coastguard station, court of law, custom house, dispensary, dock building, drill hall, exchange, fire station, gymnasium, hall, hospital, infirmary, library, literary and scientific institute, local government board office, market house, monument, municipal building / office, museum, palace, police station, post office, prison, public office, railway station, reading room, school, skating rink, theatre, wash house, water work, workhouse. You can view some of these on our Map of Public Buildings in Great Britain 1900s demonstration viewer.

Ordnance Survey Large Scale Town Plans

Detail from Sheet 17, Edinburgh 1876 . 149 Constitution Street is shown as 'P.H.', which stands for Public House (it was a pub!).

Ordnance Survey town plans are at a scale of either 1:500 (10 Feet to the Mile) or 1:1056 (Five Feet to the Mile); they are the most detailed maps ever surveyed by Ordnance Survey. These very detailed urban town plans cover all settlements with more than 4,000 inhabitants. They were surveyed from 1847-1895, and some more populous towns were surveyed more than once during this time.

The large scale town plans show walls and other divisions between all buildings, including tenements. The maps also show the ground floor layout of public buildings, such as cathedrals, churches, schools, poorhouses, prisons, and town halls. Due to the interest in public sanitation that provided the rationale for the maps, buildings of sanitary interest such as privies, taps, cow houses, cess pits, brew and bake houses, cart sheds and stables, as well as beer houses are shown.

Many of the 1:500 town plans were hand coloured, showing different types of building construction. Brick or stone buildings were coloured in red whilst metal or wooden buildings were coloured grey. Other colours and symbols indicated glass, roofed alleyways, interior building features and types of wall.

OS 25 inch to the mile maps

An extract from a 25 inch to the mile map showing our tenement in Leith, from 1896.
Detail from OS 25 Inch Edinburghshire III.4 (published 1896).

The Ordnance Survey 25 inch to the mile series (1:2,500 scale) is the most detailed OS mapping for all the inhabited areas of Britain from 1855 to the Second World War. There are two editions of these maps for all areas that were mapped (1850s-1880s and 1890s-1900s). After these editions, urban areas or places undergoing more rapid change were surveyed again. The maps cover all towns, villages and cultivated rural areas, which for Scotland comprises over a third of the total land area.

The 25 inch scale is an excellent scale for exploring buildings as they are shown clearly, with the division between each building clearly demarcated. Divisions are also shown between buildings of a different character (for example, between a residential house and an outbuilding). The maps also provide detail of features like glass roofs and closes. The immediate surroundings, including roads, gardens, trees, railways or industrial premises are also clearly shown.

On the first edition of the 25 inch maps (1850s-1880s), brick or stone buildings were coloured in carmine / red whilst metal or wooden buildings were coloured in grey. Sometimes glass buildings like greenhouses or skylights were coloured in blue.

OS Six-inch to the mile maps

The Ordnance Survey Six-inch maps (1{10,560 scale) cover the whole of Britain including rural and uninhabited areas, dating from the 1840s to the Second World War. The OS six-inch maps record practically all man-made and natural features in the landscape, including nearly all buildings. These maps are useful for rural buildings in less inhabited areas, such as farms, hamlets, or cottages. However, in more settled areas, more detailed maps at 25 inch to the mile or the OS Town plans are more useful for buildings.

Ordnance Survey National Grid maps - 1:1,250 and 1:2,500

The OS 1:1,250 mapping is the most detailed Ordnance Survey series after the Second World War for urban areas with more than about 20,000 inhabitants, from the 1940s to the present. These maps are the earliest maps to show house numbers comprehensively. Whilst not every building has a number (to avoid overcrowding on the map), enough house numbers are always shown so that a house number for every building can always be inferred. The maps also show excellent detail of related features such as railways, pavements, streets and street names, parkland and trees, paths, spot heights, and all administrative urban boundaries to scale.

The OS 1:2,500 mapping is the most detailed OS series for all inhabited areas and cultivated areas after the Second World War. It is excellent for smaller towns, villages, and rural areas without 1:1,250 coverage.

These OS National Grid maps were placed under continuous revision from their inception in the 1940s. What this means is that new editions of each map were published when there had been sufficient change on the ground to warrant a new edition for that sheet. For many urban areas undergoing more change, there are therefore successive editions of the same sheet over time, which are extremely useful for documenting changes on the ground over the decades.

We have scanned and put online all our out-of-copyright OS National Grid maps at 1:1,250, 1:2,500 and 1:10,560 scales for all of England, Scotland and Wales.

Digital Gallery - Scottish Places

The Library's Digital Gallery has images from a selection of resources, including books, views, films, photographs, and postcards relating to places in Scotland, and many of these contain information or show images about houses / buildings.


A Gazetteer is a geographical encyclopaedia. They provide information on  towns, villages, geological features, and more. On the Library's digital gallery, we have Scottish gazetteers from 1803 – 1901. These descriptive gazetteers are useful for contextual information on places. They often include lengthy descriptions about towns and cities, with details of their physical and human geography, as well as economic, administrative and statistical data. As such, they form a written complement to detailed maps and atlases, and some of these gazetteers were specifically intended to complement cartographic works.

Post Office Directories

With their alphabetical list of a location's inhabitants and information on their profession and address, the Scottish Post Office directories enable you easily to find out where people lived at a certain time and how they earned their living. All of the Post Office Directory maps are searchable in our Town Plans listings and map interface.
