important geometry rule the two source images are not two separate building wings they are two perpendicular orthographic elevations of one single rectangular main house volume left image this is the short gable end facade of the same house right image this is the long side facade of the same house these two facades meet at one 90 degree corner do not create an l shaped house do not create a projecting side wing do not turn the left facade into a separate building volume do not create a cross gable or additional large roof mass the main building footprint must remain one simple rectangular volume roof use one continuous simple gable roof over the main rectangular house the roof ridge runs parallel to the long facade the ridge continues continuously from one gable end to the opposite gable end the short facade shown in the left image is simply the gable end of this same continuous roof do not create an additional perpendicular roof create a second large gable roof create an l shaped roof create a taller central roof add dormers or skylights change roof pitch change roof height change roof overhangs the small entrance roof detail visible on the long facade must remain only a small entrance feature it must not become a separate building wing or major roof volume preserve exactly long facade length short facade width building height all proportions all wall positions all window positions and sizes all door positions and sizes sill heights roof pitch ridge height roof overhangs facade composition materials and colors create one photorealistic 3 4 perspective view from pedestrian eye level showing the long facade and the short gable end facade together final rule reconstruct the same simple rectangular house shown in the two elevations change only the camera viewpoint do not change or invent any architecture
