Planning Permission in the Republic:
6 Issues You Need to Get Right First Time

Securing planning permission in the Republic can be straightforward—if you’re well-prepared. Whether you’re planning a one-off house, renovating a cottage, or building along the coast, understanding the planning landscape is the key to avoiding costly delays or refusals. As local architects working in Donegal and the northwest for over a decade, we’ve put together this practical guide to help you navigate the planning process and get it right

Exempted Development Extension to Rear of House

House extensions may not always require planning permission.

1. Know If You Need Permission at All

Not every project requires full planning permission. You might be exempt if you’re:

  • Building a small extension (under 40m², meeting certain conditions)
  • Converting an attic without altering the roofline
  • Installing solar panels within defined limits

But if you’re constructing a new dwelling, making external changes, or building in a protected or coastal area, you will likely need full planning permission from Donegal County Council.

2. Understand Local Context: Rural Policy & Scenic Areas

  • If you’re applying in an “Area Under Strong Urban Influence” or “Areas Under Strong Holiday Home Influence” you may need to prove a local housing need.
  • Sites in “Especially High Scenic Amenity” areas (EHSA), like parts of Inishowen or Glencolmcille, face extra design scrutiny. This doesn’t mean you can’t build—but your design must respect the landscape and local character.

3. Prepare a Strong, Locally-Sensitive Application

Here’s what Donegal planners want to see:

  • A design that fits the topography and landscape, especially on elevated or exposed sites.
  • Use of natural materials—stone, slate, render, timber—over generic suburban finishes.
  • A modest form and scale, with careful attention to height, roof shape, and orientation.

As architects, we often recommend narrow gable, storey and a half or farm yard-style homes that sit more quietly into Donegal’s terrain. Avoid off-the-shelf house plans—custom, site-specific design will increase your chances of approval.

4. What to Include in Your Planning Pack

A full application includes:

  • Planning application form and fee
  • Site layout and location maps (1:1000 and 1:2500) from a licensed source
  • Full set of architectural drawings: plans, sections, and elevations
  • Design statement, especially for sensitive or EHSA areas
  • Percolation test and site suitability report (if installing a septic tank)
  • Photographs of the site and surroundings
  • Land ownership or consent letters

In coastal areas or places near Natura 2000 protected habitats, you may also need a Natura Impact Statement (NIS) or flood risk assessment.

5. Watch for Common Pit falls

Even strong applications can be delayed or refused if:

  • The site has poor access or visibility splays are not proven
  • There’s a lack of local housing need (for rural one-off homes)
  • Septic tanks are proposed on unsuitable ground
  • The design ignores local form or is overly suburban

The best way to avoid costly planning issues is to engage Usonia Architects Ltd early. Our local knowledge of county planning policies, landscape and planning history helps identify potential obstacles before they delay your project..

6. Timeline and Next Steps

Once lodged, a decision normally takes 8 weeks, but delays can happen if:

  • The council requests Further Information (FI)
  • The application needs public notice corrections
  • Specialist reports (like NIS) are incomplete

After approval, you have 5 years to commence the build. For smooth sailing:

Ensure compliance with Building Control (BCAR) if relevant

Notify the council before starting
