Property type dummies Terr/Detach/Apt (reference semi-detached); construction-period dummies Pre1919/Early Modern/Inter War (reference post-war/new build) are mapped to 'age' with x_transform dummy. 'No Garage' is reverse-coded garage dummy. EPC score = SAP energy-efficiency points (continuous); EPC bands (Model 2) are dummies with band D as reference. Tables 6-8: 'Spatial and temporal dummies available upon request' (not printed). Table 7 and Table 8 'x EPC' interaction rows (e.g. Terr x EPC = -0.405, identical to the Terr main effect) are implausible as interaction terms and are NOT extracted; Table 8 Models 6-8 and 10 therefore only contribute Floor Area and Gas Heat main effects. X*Y, Y*Y, X*X coordinate polynomials not extracted. Table 11 spatial lag models use the 961-observation subsample; W*P (spatial lag of price) not extracted.
