creation of gothic architecture
A "building unit" is an arbitrary unit of work based on bulk billing techniques used by quantity surveyors. The unit is small enough to provide realistic figures in the small churches without becoming too huge in the large. Six units would pay for one small vaulted bay in an aisle about 3 metres square, or a small first-floor gallery. Such a bay would consist of an external wall with a small window, half of two columns about 3 meters tall, the floor and footings under them and the vault and roof overhead.
The building sequence that appears here is based on a preliminary analysis of the building on-site, and has not yet been confirmed through detailed analysis of the data. For our purposes, a "phase" is defined as the work done during any particular campaign of construction. These are then assigned to the relevant decade, so there may be more than one phase of work in any particular decade. While this is certainly imperfect, it will allow us to explore costing data across time more easily. Once the data has been fully analyzed, the chronology and costing analysis will be refined, and this synopsis may be adjusted accordingly. Clicking on any of the decade graphics will display all buildings that had work being done during that decade.
John began his survey of the Paris Basin churches (between 1050 and 1250) in 1969 to complete his monograph on Chartres. During the 1980s he undertook a survey of every Early Gothic church with anything from this period, and has since then revisited them all many times during over 30 journeys. His work included images of the capitals, measured drawings of elements and profiles, and detailed lists of the building characteristics, all of which will eventually become part of this project. From 2012 onwards he has been working closely with Chris Henige to revisit all these buildings to create panoramas and models of the construction process so that all this material may be accessed through the internet.
