Infill plots wanted in Gwynedd
Development Land Wanted buys infill plots in Gwynedd and right across England and Wales. Owners and agents are both welcome.
An infill plot is a gap in an otherwise built-up frontage, between existing houses or buildings, where one or more new homes could fit. These small sites are often in sought-after streets and can be well suited to planning.

Is your land in Gwynedd the kind we want?
Gwynedd, as used here, covers north-west Wales and Anglesey, including Bangor, Caernarfon, Holyhead, Llangefni, Porthmadog and Pwllheli. Eryri National Park and the Llŷn and Anglesey National Landscapes cover much of the land, and there is no green belt. Sites tend to be small: edge-of-village land, infill plots, farm buildings and brownfield land in the towns, with Welsh language impact and local housing need often central to decisions.
- Gaps in a street frontage between houses or other buildings
- Corner plots within built-up areas
- 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.
Before we make an offer in Gwynedd
Character of the street
New homes need to suit the building line, height and spacing of the street.
Neighbours' amenity
Overlooking, loss of light and outlook are the issues planners weigh most often.
Parking and access
A safe access and enough parking can decide small schemes.
The Planning (Wales) Act 2026 received Royal Assent on 27 April 2026 and is being brought into force in stages, consolidating Welsh planning law into a single Welsh framework.
In Wales a planning permission usually lasts five years before work must begin, and land purchases are subject to Land Transaction Tax rather than Stamp Duty Land Tax.

Your questions answered
Can I sell a plot next to my own house?
Often, yes. We make sure access, boundaries and services are set out so your own home is protected.
Do small infill sites need biodiversity net gain?
In England, from 6 August 2026 most non-major sites of 0.2 hectares or less are exempt from mandatory BNG, unless priority habitat is affected. Wales uses a different approach.
Can an agent introduce land in Gwynedd to you?
Yes. Estate agents, land agents and planning consultants can introduce sites with the owner's consent. Any fee is agreed in writing before details are shared, confirmed by the owner in writing and paid only on completion.
Do I need to pay anything to have land in Gwynedd assessed?
No. Our appraisal is free and there is no obligation to sell to us.
