Lay out the kinds of sources and places in the UK that answer each part (deeds, census-type records, old maps, local archives, newspaper archives), what each one can and cannot tell them, and the sensible order to work in. No URLs — the shape of the search, not links.", "output": "Tracing the history of a 1930s semi-detached house in Leicester is a brilliant project. The 1930s was a boom time for suburban expansion in the city, with ribbons of new housing stretching out along arterial roads and swallowing up old farmland. \n\nTo avoid getting overwhelmed, house history should be tackled like an archaeological dig: starting with what you have right now and digging backward in time. Here is the sensible order to work in, the sources to use, and what each will (and won’t) reveal.\n\n---\n\n### Phase 1: The House Itself (Start at Home)\n\n**1. Title Deeds and Land Registry Records**\n* **Where to look:** HM Land Registry (for the current title register) and your own files. If the house has a mortgage, the lender may hold the historical bundle of deeds, though many were returned to owners when property registration became digital.\n* **What it CAN tell you:** The Title Register will show the current boundaries and any restrictive covenants (e.g., \"no keeping of pigs,\" a common 1930s stipulation). An original bundle of deeds is the holy grail: it can contain the original conveyance document from the 1930s, naming the developer who bought the farmland, the builder, the first owner, and the original purchase price.\n* **What it CANNOT tell you:** Who actually *lived* there. Deeds record ownership, not occupancy. A landlord may have bought the house and rented it out.\n\n### Phase 2: The Land and the Build (Setting the Scene)\n\n**2. Historic Ordnance Survey (OS) Maps**\n* **Where to look:** The Record Office for Leicestershire, Leicester & Rutland (ROLLR), local reference libraries, or national map archives.\n* **What it CAN tell you:** What stood on the land before. By comparing the 1910s, 1920s, and 1930s OS maps of Leicester, you can watch your street appear. You might find your house was built on an old Victorian brickworks, a market garden, or a medieval ridge-and-furrow field. It also narrows down the date of construction (e.g., if the house isn't on the 1932 map but is on the 1938 map).\n* **What it CANNOT tell you:** The exact year the house was built, the name of the builder, or who lived inside.\n\n**3. Building Control and Planning Applications**\n* **Where to look:** The local archives (ROLLR) or Leicester City Council’s planning department archives.\n* **What it CAN tell you:** The exact date the house was approved for construction. You can often find the original architect’s blueprints, the drainage plans, the name of the building firm, and the developer. \n* **What it CANNOT tell you:** Whether the builder actually stuck to the plans (modifications were common during the build), or when the first resident unpacked their bags.\n\n### Phase 3: The People (Filling the House)\n\n**4. The 1939 Register**\n* **Where to look:** National Archives (accessible via major family history platforms). \n* **Context:** The 1931 census was destroyed by fire, and the 1941 census was cancelled due to WWII. Therefore, the 1939 Register—taken to issue ration cards—is the most vital document for a 1930s house.\n* **What it CAN tell you:** Exactly who was sleeping in your house on the eve of the Second World War. It lists full names, exact dates of birth, and occupations (e.g., \"hosiery worker,\" \"shoe machinist\"—classic Leicester trades). It will also show if they took in evacuees.\n* **What it CANNOT tell you:** Anyone born less than 100 years ago whose death hasn't been proven (their records will be blacked out for privacy). It also won't tell you where they moved from.\n\n**5. Street Directories (e.g., Kelly’s Directories)**\n* **Where to look:** Local reference libraries and local archives.\n* **What it CAN tell you:** Who the \"head of household\" was, year by year. Because directories were published annually, you can track exactly when the house first appears in print, and follow the turnover of residents through the decades. They often list the resident's occupation.\n* **What it CANNOT tell you:** The names of wives, children, or lodgers. Directories usually only listed the primary (usually male) householder.\n\n**6. Electoral Registers**\n* **Where to look:** Local archives (ROLLR) or the British Library.\n* **What it CAN tell you:** Every adult of voting age living in the house, year by year. This fills in the gaps left by the street directories, revealing spouses, adult children, and lodgers.\n* **What it CANNOT tell you:** Anyone under the age of 21 (or 18 in later years), their occupations, or how the people in the house were related to one another.\n\n### Phase 4: The Stories (Adding Color)\n\n**7. Local Newspaper Archives**\n* **Where to look:** Local libraries (on microfilm) or the British Newspaper Archive (which includes papers like the *Leicester Mercury*, *Leicester Chronicle*, and *Leicester Evening Mail*).\n* **What it CAN tell you:** The marketing of the house. You can often find the original 1930s advertisements for your housing estate, boasting about \"modern conveniences\" and listing the asking price. Later on, searching your exact address might yield birth, marriage, and death notices, or stories of local events, burglaries, or street parties involving previous residents.\n* **What it CANNOT tell you:** A complete history. Newspapers are entirely hit-or-miss; your house will only appear if it, or its residents, did something newsworthy or paid for an announcement.\n\n### Summary of the Sensible Order:\n1. **Check your own deeds/Title Register** to establish boundaries and trace ownership backward.\n2. **Look at OS Maps** to see what the land was before the 1930s and narrow down the build date.\n3. **Search Planning Records** to find the builder and original blueprints.\n4. **Check the 1939 Register** to find the first (or very early) occupants and their wartime jobs.\n5. **Use Directories and Electoral Registers** to create a timeline of who lived there from the 1940s to the present.\n6. **Search Newspapers** using the names you found in step 5 to uncover the personal stories of the people who called your house a home.", "latency_ms": 24592, "cost": 0.034198, "task_score": 8, "judges": [ { "judge": "anthropic/claude-sonnet-5", "score": 8, "violates": false, "reasoning": "Accurate, well-organized, follows no-URL constraint, covers deeds, maps, census-type records, archives, newspapers with capabilities/limits and sensible order.
