What size shed can I build in Ireland without planning permission?

Irish planning regulations include a size exemption for garden sheds that often surprises first-time buyers. Under the Exempted Development rules, a garden shed up to 25 square metres (roughly a 3m × 8m structure) can be built without planning permission, provided it sits at least 2 metres from any boundary and isn’t used for human habitation. The 7-year boundary rule — which allows structures on shared boundaries if they’ve existed for 7 years without objection — adds another layer worth understanding before you commit to a location.

Garden Shed Planning Permission Ireland: Size Exemption Guide [2024]

• Garden sheds up to 25 m² = exempt from planning permission in most residential settings
• Minimum 2m setback from all boundaries required for exemption to apply
• Sheds cannot be used as sleeping quarters or permanent living spaces
• structures near scheduled monuments or protected sites face additional restrictions

Do garden sheds need foundations?

The short answer is yes, every garden shed needs some form of base — but the type depends on your soil conditions and shed material. Without a proper foundation, even the most expensive steel shed will eventually sag, warp, or rust where it contacts damp ground. The common mistake buyers make is assuming a “flat enough” patch of grass is sufficient.

Do you really need a foundation for a shed?

• Concrete slab: most durable option, ideal for heavy timber and metal sheds, costs €200-500 depending on size
• Raised timber frame: suitable for plastic and light metal sheds on uneven ground
• Gravel base with grid: budget-friendly drainage-friendly option for temporary or lightweight structures
• Plastic grid bases (e.g., Keter): interlocking panels filled with gravel, designed specifically for plastic sheds

Do I need to put anything under a plastic shed?

Yes — plastic sheds benefit just as much from a solid base as timber or metal variants. Without one, the plastic panels can bow under concentrated loads (from stored tools or pressure from shelving) and moisture can seep up through the floor. A simple gravel-filled plastic grid base costs around €80-120 and provides both drainage and level support without the expense of a full concrete pour.

Is it better to get a metal or plastic shed?

The metal versus plastic debate hinges largely on your priorities: if security and longevity are paramount, steel wins; if ease of assembly and upfront cost matter more, plastic holds its own. Both materials have genuine drawbacks that the sales copy tends to gloss over.

What are the problems with plastic sheds?

• UV degradation: plastic sheds can become brittle and discoloured within 5-7 years of continuous sun exposure
• Limited security: thin plastic panels are easier to cut through than steel
• Wind resistance: lighter plastic sheds may require anchoring in exposed Irish gardens
• Temperature sensitivity: plastic expands and contracts more than metal, potentially causing warping in poorly fitted doors

Plastic shed vs metal shed vs timber shed: which is best for you?

Four data points from current DoneDeal listings illustrate the price-performance trade-off across materials:

The €150 difference between the basic 6×4 and the Deluxe Timber Bike Shed reflects the material premium — timber adds visual appeal and insulation but requires more maintenance than steel or plastic.

What type of shed lasts the longest?

Long-term durability data consistently points to treated timber and powder-coated steel as the longest-lasting materials, with properly maintained timber structures surviving 15-20 years and steel sheds reaching 20+ years without significant corrosion if the coating remains intact.

Resin vs. Wood vs. Vinyl vs. Metal Sheds

• Metal (powder-coated steel): 20-25 years average lifespan; requires checking coating integrity annually
• Treated timber: 15-20 years with regular sealing; vulnerable to rot if drainage is poor
• Vinyl: 10-15 years; relatively low maintenance but limited customisation options
• Resin/Plastic: 7-12 years; cheapest upfront but highest replacement rate

What is the cheapest time of year to buy a shed?

Seasonal demand patterns on DoneDeal reveal a clear pattern: listings spike in March through June as Irish homeowners tackle spring garden projects, then ease through September to November. This means buyers who shop in late autumn and early winter typically face less competition and more motivated sellers willing to negotiate.

When is the Best Time to Buy & Save on Shed

• Best deals: October through February — seller urgency increases as spring buying rush fades
• Peak pricing: March through May — highest demand drives listings up and reduces negotiating room
• DoneDeal specifically: searching “garden sheds for less” returns 1,186 ads currently, with a subset of winter-listed items at reduced prices
• Clearance sales: Shed Factory Ireland showrooms in Belfast and Dublin occasionally run winter clearance events

Material Comparison

Six shed types currently listed across DoneDeal illustrate the material trade-offs buyers face.

The jump from €550 basic models to the €900 steel Alpine represents a €350 premium — but one that translates to roughly 8-13 additional years of maintenance-free use.

Shed Specifications by Type

Eight verified price points from DoneDeal and Irish suppliers show how size and material combine to determine cost.

Pricing clusters into three tiers — entry-level (€550-700), mid-range steel and timber (€700-900), and premium composite garden rooms (€1,870-3,699). Buyers with tighter budgets should focus on entry-level models in spring when new stock is most available.

Steps: How to Buy a Garden Shed in Ireland

1. Determine your size and planning exemption status

• Measure your available garden space, remembering the 2m boundary rule
• Calculate whether your intended shed (under 25 m²) qualifies for exemption
• Check with your local authority if your property is near a protected site or scheduled monument

2. Set your budget and material preference

• Entry-level buyers: €550-700 covers basic new or timber options
• Long-term investment: €900+ for powder-coated steel or composite
• Consider annual maintenance costs — timber requires re-sealing every 2-3 years

3. Search DoneDeal with specific queries

• Start with DoneDeal Ireland (garden sheds all sections) — 724 ads currently available
• Filter by your region (Dublin, Kildare, Cork, Kilkenny) to reduce collection distances
• Check DoneDeal’s used garden sheds category if budget is primary constraint — 240 ads currently listed

4. Verify condition before purchase

• Request photos of interior floor and wall panels if listing lacks detail
• Ask about storage history — sheds kept damp before sale may have hidden mould
• For metal sheds: check coating integrity and look for rust at panel joins

5. Arrange foundation and delivery

• Source gravel or concrete base materials before shed delivery arrives
• Confirm delivery costs with seller — many DoneDeal listings specify “collection only”
• Alpine steel sheds offer 3-day delivery in Naas, Kildare — use this as a delivery benchmark

For Irish buyers willing to invest the time, DoneDeal’s 1,696 shed and glasshouse listings offer genuine variety — from €550 entry-level 6×4 models in Dublin 18 to €3,699 composite garden rooms in Kilkenny. The trick is matching your material choice to your actual timeline: a shed you plan to replace in 5 years doesn’t justify the steel premium, but homeowners in their forever home should count the cost-per-year rather than the upfront price alone.
