The built environment in and around Ivybridge is mainly characterised by its suburban streets plans and houses, although in the centre of Ivybridge it's mainly characterised by Victorian buildings. From the centre of the town most buildings are terraced and now many of these buildings have been converted into retail outlets along Fore Street – the town's central business district. In the middle layer of the town most buildings are semi-detached and built on quite steep roads. More detached houses are found on the outer layers of the city on the east and on the west of the town. Over the past decades the town has been shaped by its two most essential pieces of infrastructure: the railway line to the north and the A38 dual carriageway to the south. No large scaling housing has been built on either side of these boundaries. Due to this Ivybridge has been forced to grow east and west rather than north and south; it stretches approximately from east to west and from north to south.
