1. Why use this guide?

Use this guide for an overview of The National Archives’ collection of architectural drawings and related records and for advice on how to find them among our vast holdings.

The guide does not cover building contracts, accounts or correspondence.

We do not hold any architectural models.

Copies of all of the architectural drawings illustrated in this guide are available to buy through our Image Library.

2. What kinds of architectural drawings do we hold?

The National Archives holds many thousands of architectural drawings and related records, covering a very wide range of buildings and other structures, most of which date from the 18th, 19th and 20th centuries. These include plans, elevations, sections, perspective drawings and various other depictions and details of architectural works, including some iconic British landmarks and major engineering projects. We also hold site plans, which range from elaborate depictions of houses and grounds to simple outline block plans.

Before the 20th century the British government’s interest in architecture was largely confined to public and Crown buildings and schemes, and works by local authorities under various acts of Parliament. The records we hold very rarely represent the full range of drawings produced for any building project; we usually hold only a handful for a particular structure or scheme, although in a few cases a large number have survived (notably for the Houses of Parliament and the Royal Courts of Justice). Many older plans and drawings have not survived, and large numbers are held by other institutions (see section 7).

Because of the Crown’s landholdings, and litigation relating to privately-owned land, we hold some records of buildings and structures on landed estates; but except in the case of the Crown Estate we are seldom the best place to start a search for such material.

2.1 Crown Estate buildings

The majority of our architectural drawings relate to buildings which form part of the Crown Estate or have been the responsibility of the Office of Works and its successor departments and agencies. Among these are:

  • royal palaces
  • the Houses of Parliament
  • government buildings
  • buildings constructed for or used by the armed services
  • ancient monuments
  • works for ceremonial events such as coronations and state funerals

Many drawings are held among the records of the Crown Estate Commissioners, and the Office of Land Revenue Records and Enrolments and its predecessors and associated departments.

2.2 Municipal buildings and public works

A ground floor plan of Wandsworth County Court in 1858, held among the records of the Office of Works and its successors (catalogue reference WORK 30/758).

We hold a range of drawings and plans relating to local municipal buildings, including schools, hospitals, poor law buildings, Metropolitan Police stations and other civic structures. The majority among the records of the Ministry of Housing and Local Government and successor and related bodies.

We also hold various plans relating to substantial complexes, such as housing estates, naval dockyards, or the Festival of Britain site, as well as a range of other sites and buildings.

2.3 Public transport constructions

Many plans and drawings of railway stations and hotels are among the records of pre-nationalisation railway, canal and related companies in the British Transport Historical Collection and those created or inherited by the British Transport Commission, British Railways Board and successors.

2.4 Buildings and constructions overseas

We also hold drawings of buildings and structures outside the British Isles, which were created or collected in the course of British government business abroad and in the work of the armed services, both in foreign countries and, during the years of the British Empire, colonies. Drawings of fortifications are particularly well-represented.

Plans and drawings from overseas are held among, though are not exclusive to, the records of the following departments:

The place to start a search is our online catalogue (see 3.1). However, many drawings are not listed in our catalogue, often because they belong to larger documents (‘parent’ files) whose catalogue descriptions are limited to broad details. Drawings are often filed or bound up with correspondence and other records generated in the course of the government business of which they formed a part. Some government departments created discrete series of maps and plans but even with these departments there are likely to be at least as many drawings among their respective text-based records.

The most detailed listings of drawings are those that appear in the published and unpublished catalogues, available in The National Archives library and reading rooms in Kew. If your online catalogue searches are unsuccessful you should turn to these paper catalogues (see 3.2 and 3.3), though you will need to visit us to do so.

As a last resort you can return to the online catalogue and try speculative searches of the records by searching for ‘parent’ files. For example, to find architectural drawings of a hospital you could try a search within Ministry of Health files for the area where the hospital is located, or for ‘hospital building programmes’ or any other description that may match your research topic.

3.1 Using our online catalogue

You can find some architectural drawings (usually described as ‘plans’) by using keywords to search for the short descriptions of them in our online catalogue. Some drawings and plans are individually described, others are only described as forming part of a file or a whole series in a wider description.

Start a search with the name of the building or structure; you can narrow searches by combining the name with terms such as:

  • Plan/s
  • Survey plans
  • Diagram
  • Drawings
  • Cross-section
  • Layout
  • Elevation
  • an architectural feature such as ‘foundations’, ‘towers’ and so on

Bear in mind that searching with ‘plan’ will find references to ‘plans’ and ‘planning’ which have nothing to do with architecture.

To target the records of a specific department, use the advanced search of our catalogue or the key series described in section 5 of this guide.

3.2. Using published catalogues available at our library and libraries elsewhere

Four volumes of Maps and Plans in the Public Record Office describe architectural plans and drawings, as well as maps, held at The National Archives (formerly the Public Record Office). Contents are arranged topographically under country names in use at the date of publication, and then chronologically within each region, country or place. They contain indexes of draughtsmen, surveyors, architects and cartographers, but not of subjects. The four volumes are:

3.3. Using unpublished catalogues available only at our building in Kew

The following resources, created by the Public Record Office, the forerunner of The National Archives, are held in the Map and Large Document Room at our building in Kew.

Searching by person: card catalogue

A card with handwritten script briefly describing three sites, from the 'Mapmakers' card catalogue indicating the document references for architectural drawings by Marc Isambard Brunel, an engineer, father of Isambard Kingdom Brunel.

A card from the ‘Mapmakers’ card catalogue indicating the document references for architectural drawings by Marc Isambard Brunel, an engineer, father of Isambard Kingdom Brunel.

A set of drawers, labelled ‘Mapmakers’, contains a card catalogue of maps, plans and architectural drawings of various kinds. Indexed by the names of draughtsmen, surveyors, engineers, architects and cartographers, each entry provides very brief details of what is depicted in the document and the accompanying catalogue reference.

Searching by place: card catalogue

This card catalogue contains information about drawings that have come to light since the publication of the catalogues described in section 3.2 and includes places that they do not cover. It is arranged topographically, by names of countries as they were at the date of cataloguing.

Searching by place or subject: maps and plans summary catalogues

Part of the Summary Catalogue in our reading rooms at Kew.

Part of the Summary Catalogue and the draft catalogue for maps and plans from Japan in our reading rooms at Kew.

For a few years in the late 1980s and early 1990s, maps, plans and drawings found with documents in series not consisting wholly of graphic material were recorded in a summary catalogue.

The catalogues are arranged topographically across a dozen or so files and there are three separate files providing subject indexes. The topographical and subject indexes both provide full document references.

Draft catalogue for maps and plans from Japan

A draft, manuscript catalogue of ‘Maps and plans’ for locations and constructions in Japan. It is arranged topographically.

4. How to search for the plans and drawings of specific architects

Not all the plans and drawings in our collection can be attributed to a specific architect but in some cases they are signed or otherwise identified as the work of a particular individual.

You can search by architects’ names in the following ways, though none of these methods offers a comprehensive search of the records:

  • Search our catalogue using an architect’s name as your search term
  • Consult the indexes of architects, draughtsmen and surveyors in the published and unpublished catalogues (see sections 3.2 and 3.3)
  • Use the subject heading for architects and surveyors which forms part of the ‘Maps and plans summary catalogue’ (see section 3.3)
  • Use the typescript index of signed drawings among the records of the Office of Works and successors (this index is not wholly reliable)

5. Key records series

The three tables in this section highlight those record series containing significant quantities of maps, plans and drawings relating to architecture and the built environment. These series were inherited from various government departments, notably the former Office of Works, which accumulated series of records consisting wholly or largely of plans and drawings of buildings, or maps illustrating aspects of the built environment, usually in relation to planning and development. Many architectural plans and drawings were filed in series which consisted principally of maps.

Click on the series references below to search within the respective series but keep in mind the following limitations:

  • Catalogue descriptions seldom indicate the drawing material or medium.
  • Catalogue descriptions seldom record the stage in the building project at which a particular drawing or set of drawings was produced (for example, presentation drawings, contract drawings, working drawings, record/as built drawings). In some cases, this can be determined from the drawings themselves, but it is not always easy to establish.

The tables overlap in places, and you can expect to find some types of drawings and plans in series appearing in more than one of these tables.

5.1. Drawings and plans of specific buildings, sites and schemes

A drawing from 1739 showing William Kent's Italianate design for the Houses of Parliament (catalogue reference WORK 29/3358). The plan did not make it past the drawing board.

Copies of a card index created by the Office of Works contains information on the drawings in the various Office of Works series (department reference WORK) listed below, and is available in the Map and Large Document Reading Room at Kew. The card index provides a useful way to find records in the absence of detail in catalogue descriptions.
