The infill plots that interests us around Porthmadog
Around Porthmadog, infill plots are often side gardens or gaps left between older houses; the street's character usually sets the design. Porthmadog lies about 16 miles south of Caernarfon in Gwynedd. We also cover Pwllheli, Caernarfon, Bangor and the villages between them.
- Corner plots within built-up areas
- Small yards or garages between houses
- Plots large enough for one or more homes with parking
- Land with or without an earlier planning history
Controls on turning homes into second homes or holiday lets have been introduced in parts of the area, reflecting pressure on local housing. Coastal flood risk under TAN 15, and the A55 corridor along the north coast to Holyhead, influence where larger schemes are most likely to be supported.

Character of the street
New homes need to suit the building line, height and spacing of the street.

A safe access and enough parking can decide small schemes.
Services
