A PlotNua Discovery

The Outdoor Room

What if the space outside your back door became your favourite room?

Make more of the space between your house and your garden.

Illustrative AI-generated visualisation. Not an actual installation.

The possibility

A patio is used on the few days the weather allows. A room is used every day.

Most Irish homes already have the space: a terrace or a patio right outside the kitchen doors, used for a handful of warm evenings and left to the rain for the rest of the year.

Give it a roof, a side that closes, light and a little warmth, and the same few square metres become somewhere you sit through a shower, eat on a cool evening and cook when it drizzles. It isn’t a new building at the end of the garden. It’s the room between the house and the garden.

The possibilities

Five rooms you didn’t know you had.

Each starts from the same patio. What changes is how much of the weather it keeps out, how open it stays, and what you’ll use it for.

Five kinds of outdoor room

  • The Covered Patio: a glass lean-to roof on slim anthracite posts over a stone terrace behind a rendered house, with an outdoor sofa, lanterns, potted olive trees, hydrangeas and lavender.
    Illustrative AI-generated visualisation. Not an actual installation.

    The Covered Patio

    A fixed roof of glass or polycarbonate on slim posts, fixed to the back wall above the doors: a lean-to veranda.

    What it gives
    Shelter from rain over the doors and the furniture, while the sides stay open to the garden.
    Best for
    Sitting out in a shower, a dry route to the garden, furniture that stays out.
    Consider
    It keeps the rain off, not the wind. Glass is quieter in rain and stays clear; polycarbonate is lighter and usually costs less.
  • The Glass Room: the terrace closed in with full-height sliding glass walls on a slim anthracite frame, a sofa and a floor lamp inside and the lawn and borders beyond.
    Illustrative AI-generated visualisation. Not an actual installation.

    The Glass Room

    The covered patio closed in with sliding glass walls on one or more sides, which open right back when the day allows.

    What it gives
    A sheltered, bright room with the whole garden in view, for three seasons of the year.
    Best for
    Breakfast, reading, plants, children’s play on a windy day.
    Consider
    Sliding glass is weatherproof rather than fully watertight, and its rails need a dead-level base. Enclosed against the house, it is most likely treated as a house extension for planning (chapter 04). It isn’t an insulated, heated room: that is closer to a sunroom or conservatory (below).
  • The Outdoor Dining Room: a long timber table with woven chairs and lanterns under a flat roof with a timber ceiling and recessed lights, beside the house's glazed doors.
    Illustrative AI-generated visualisation. Not an actual installation.

    The Outdoor Dining Room

    A covered area sized around the table, with lighting under the roof and heat for the cooler evenings.

    What it gives
    A place to eat outside that doesn’t depend on the forecast, and a room for family gatherings.
    Best for
    Summer evenings that turn cold, birthdays, long lunches.
    Consider
    Size it for the table plus room to pull chairs out. Lighting and heaters need outdoor-rated electrics, fitted by a Registered Electrical Contractor.
  • The Flexible Pergola: an anthracite aluminium pergola with its roof louvres tilted open, sunlight striping the terrace and an outdoor lounge beneath.
    Illustrative AI-generated visualisation. Not an actual installation.

    The Flexible Pergola

    A pergola whose roof louvres tilt, or slide right open, often by remote, so the same space works in sun, shower and wind.

    What it gives
    Sun when it’s out, cover when it isn’t, and air either way.
    Best for
    Changeable days, south-facing terraces that get too hot, a room that can open to the sky.
    Consider
    Usually the most expensive roof. Ask how it drains with the louvres closed, what wind it is rated for, and what happens to the motor in winter. Free-standing, it falls under a different planning class (chapter 04).
  • The Outdoor Kitchen: a covered terrace with a built-in grill, a wood-fired oven and prep counters, recessed lighting and a dining table with woven chairs.
    Illustrative AI-generated visualisation. Not an actual installation.

    The Outdoor Kitchen

    A grill and a prep counter, or a self-contained cooking unit, under a roof right next to the back door.

    What it gives
    Cooking that survives a shower, and a host who stays with the guests.
    Best for
    People who barbecue all year, and terraces already used for dining.
    Consider
    Plan gas, power, water and ventilation from the start, and keep the grill clear of the roof and anything that burns. The roof and the kitchen are usually bought separately, often from different makers.
Glass room, sunroom or conservatory?

Different names for overlapping rooms

Makers use these names loosely, and the same room can be sold under any of them. Broadly, a glass room is a covered patio closed in with sliding glass: bright and sheltered, but not insulated or heated. A conservatory traditionally has a glazed roof and mostly glazed walls. A sunroom more often has a solid, insulated roof with large windows. A glazed extension is built like any other extension, with large areas of glass.

Planning

The name doesn’t decide the rules

Whatever it is called, a glazed room attached to the back of the house is most likely treated as a house extension, and shares that allowance (chapter 04). Whether a particular one is exempt depends on its size, position, height and what is already built. Extend the House sets out the house-extension rules in full.

Comparing offers

Ask what is built, not what it’s called

Is the roof glass, polycarbonate, or solid and insulated? Are the walls sliding single glazing, or sealed double or triple glazing? Does it stand on a foundation with an insulated floor? Will it be heated, and can a door close it off from the house?

Not a building at the end of the garden. The room between the house and the garden.

Built for Irish weather

Rain, wind and the long grey evenings.

An outdoor room in Ireland is judged on a wet Tuesday, not a sunny Saturday. These are the parts that decide whether it gets used.

How an outdoor room handles Irish weather

How a covered outdoor room deals with rain, wind and cold. Not to scale. A roof is fixed to the back wall of the house and carried at the front on a post. Rain runs off the roof into a gutter hidden in the front beam, then down a pipe inside the post to a drain. The post stands on a concrete footing. A sliding glass side closes the room against the wind. A heater on the house wall and a light strip under the roof beam make it usable on cool evenings. Inset: adjustable louvres closed for rain, angled for shade and air, and open for sun. 1 Roofglass, polycarbonate or louvres 2 Gutter in the beam 3 Downpipeinside the post,to a drain 4 Footing 5 Sliding glass side 6 Heater 7 Lighting under the beam Wind Louvres: closed for rain angled for shade and air open for sun NOT TO SCALE How a covered outdoor room deals with rain, wind and cold.

  1. RoofThe roof keeps the rain off. It should fall slightly away from the house so water runs to the front, and be sealed where it meets the wall.
  2. Gutter in the beamMany aluminium systems hide the gutter in the front beam, so the roof edge stays clean and nothing drips on the way in.
  3. Downpipe inside the postThe water runs down inside a post to ground level. It still has to go somewhere: to a drain or a soakaway, never onto the patio or a neighbour’s side.
  4. FootingPosts stand on concrete footings, not on loose slabs. A free-standing structure relies on them entirely, in the wind as well as under its own weight.
  5. Sliding glass sideWind, not rain, is what usually empties an Irish patio. One glazed or screened side facing the prevailing wind changes how often the room is used.
  6. HeaterInfrared heaters warm people and furniture rather than the open air, which is why they suit a space that is never fully closed.
  7. Lighting under the beamDimmable warm light built into the beam or the louvres turns an evening on the terrace into an evening in a room.
Roofing materials

What goes overhead.

Fixed

Glass

Laminated or toughened safety glass. Clear, quiet in rain and long-lasting. Heavier, so the frame and footings work harder. Clean it with a soft cloth and a pH-neutral cleaner.

Fixed

Polycarbonate

Lighter multiwall sheets, clear, opal or tinted. Usually the lower-cost roof, and lets light through without glare. Louder in heavy rain than glass.

Adjustable

Louvres

Aluminium blades that tilt, and on some systems slide back, usually by motor. Closed, they shed rain into the beam’s gutter; open, they let in sun and air. Moving parts need looking after.

Retractable

Fabric

A waterproof fabric roof that folds back on rails. Bright when open, sheltered when closed. Best where shade matters as much as rain, and on less exposed sites.

Upkeep

Looking after it

Powder-coated aluminium needs little more than a wash. Clear leaves from the gutter in the beam each autumn, check the seal along the house wall, keep the sliding rails clean so the panels run freely, and ask how motorised louvres and their sensors are serviced.

Weatherproof isn’t the same as watertight: in driving rain a glass room can let a little water in at the edges. Ask the maker what its system is designed to keep out.

Choosing

Which one suits your space?

Start with what stops you using the patio now: rain, wind, cold, or the dark. Then with how you’d use it.

Planning and building regulations

What can you build without planning permission?

Often quite a lot, if it stays within the limits. But an outdoor room shares those limits with other things you may already have built, or may want to build.

Changed on 27 July 2026

Two allowances, both shared.

New exempted-development regulations came into force on 27 July 2026. Two of the changes matter here: a bigger allowance for extending the house, and a bigger allowance for structures in the garden. Which one an outdoor room falls under depends on how it is built and where it stands.

Established

What the regulations say, as amended on 27 July 2026. Every limit applies together, and each comes with further conditions.

House extensions · Class 1 45 m2 to the rear of the house was 40 m²
  • Covers an extension, including a conservatory, to the rear of the house only.
  • The 45 m² includes every extension built since 1 October 1964, even those with planning permission.
  • At least 25 m² of private open space must remain.
  • Walls no higher than the rear wall of the house (its side walls where the rear has a gable); a flat roof no higher than the eaves or parapet.
  • Ground-floor windows at least 1 metre from the boundary they face; the roof can’t be used as a balcony or terrace.
  • Applies to the main house only.

Shared with: a kitchen or living-room extension, a conservatory, or a converted garage.

Structures in the garden · Class 3 30 m2 in total, for all of them was 25 m²
  • Covers tents, awnings, shades, greenhouses, garages, sheds and similar structures.
  • The 30 m² is for all such structures together, including any already there.
  • Never forward of the front wall of the house.
  • At least 25 m² of private open space must remain to the rear or side.
  • No higher than 3 metres, or 4 metres with a tiled or slated pitched roof.
  • Not for living in.

Shared with: a shed, a greenhouse, or a garden room built under the same class.

Confirm individually

How the classes apply to a particular outdoor room is a judgement about its design and position. These are PlotNua’s reading, not legal advice, and councils can reach different views.

Anything at the side or front of the houseOutside the house-extension exemptionClass 1 covers the rear only, and Class 3 never allows a structure forward of the front wallPlan for permission
When exemptions don’t apply

Some homes can’t use them

The exemptions can be lost for a protected structure, in an Architectural Conservation Area, or where a condition of the house’s original planning permission rules them out. Check before anything is ordered.

A formal answer

Ask for a Section 5 declaration

Any homeowner can ask the council whether a particular proposal is exempted development. The fee is €80, and the council is due to decide within four weeks, unless it asks for more information. Its decision can be referred to An Bord Pleanála.

Building regulations

A separate test

Planning and building regulations are different questions. A single-storey conservatory, porch, carport or covered area added to a house is exempt from the Building Regulations up to 23 m² and 3 metres high (4 metres with a pitched roof). Larger work, and electrics, gas and drainage in any case, must still be done properly by competent trades.

PlotNua can’t tell you whether a particular outdoor room at your home is exempt from planning permission, and no maker’s general statement can either: the tests are about its size, position, height and what is already built. Last checked 4 November 2026 against the regulations as amended on 27 July 2026.

Questions to ask

Start with how you’ll use it, not with the roof.

Whoever you talk to, these questions help you compare like with like.

  1. What stops us using the patio now: rain, wind, cold or the dark? Which side does the wind come from?
  2. Is it fixed to the house or free-standing, and which planning class does that put it in here?
  3. How much of our 45 m² extension allowance, or our 30 m² garden-structure allowance, is already used?
  4. What footings does it need on our ground, and who designs them?
  5. Where does the rainwater go, and can our drains take it?
  6. What wind is it designed for, open and closed?
  7. Which roof: glass, polycarbonate, louvres or fabric, and why for us?
  8. What do the heaters and lighting need, and who wires them?
  9. What does the price include: groundwork, electrics, VAT, removal of the old patio?
  10. What does the warranty cover, and who services the motors and seals?
