Building a garden home in Enfield: local planning notes

Enfield has no Architectural Conservation Area. The Meath County Development Plan 2021–2027 lists 17 protected structures and five zones of archaeological potential in the town. The section of the Royal Canal that runs through Enfield is part of the Royal Canal proposed Natural Heritage Area, and the plan says development must not harm its ecological or historic value, which matters if your garden backs onto the canal.

The plan describes a town that has grown compactly on both sides of the R148, the old N4, with the Enfield Outer Relief Road to the south, and it aims to keep new building within the relief road and the canal. It also encourages the redevelopment of backland sites, the land behind existing frontages, including for housing.

Enfield is on public sewer. The Enfield wastewater treatment plant, which also serves Johnstown Bridge in Co. Kildare, was upgraded and back in operation in March 2025, sized for a population equivalent of 6,200. The 2021 plan’s note of limited capacity predates that work; Uisce Éireann’s April 2026 register now shows it as green. Class 3A allows no separate connection, so a garden home links into the main house’s existing services.

Enfield was not a CFRAM Area for Further Assessment, unlike nearby Johnstown Bridge. Meath’s flood risk assessment records flooding that recurs after heavy rainfall but judges the risk generally low, and the plan asks new development to manage surface water. Enfield is in the Trim Municipal District, whose office is Mornington House on the Summerhill Road in Trim.

The national conditions, which apply in Enfield too

The national Class 3A exemption applies in Enfield as it does across Ireland. A garden home of 32–45 m² can go ahead without planning permission when all of these hold:

It is a detached home of 32–45 m², measured on the external footprint, in the rear garden of your main house — counted together with any earlier Class 3 garden structures.
At least 25 m² of private garden remains for the main house.
It sits at least 0.6 m from every boundary, and its windows are at least 0.6 m from the boundary they face.
It has its own pedestrian access within the garden, with no new entrance onto the road.
It is no higher than 3 m (4 m with a tiled or slated pitched roof).
You live in the main house as your sole or main residence, and the garden home is never sold separately or let short-term.
Meath County Council is notified at least 14 days before work starts, with the location and Eircode of the property.
Work starts and finishes by 31 December 2030.

We check your site against every condition at the free site visit. Sizes above 45 m² need standard planning permission from Meath County Council, which we apply for on your behalf.

Enfield FAQ

Garden homes in Enfield: your questions

Do I need planning permission for a granny flat in Enfield?+

In most cases, not for a garden home of 32–45 m². Enfield follows the same national rules as everywhere else: under S.I. No. 340/2026 (Class 3A), a detached home of 32–45 m² in the rear garden of your main house is exempt from planning permission if at least 25 m² of garden remains, it sits 0.6 m from every boundary, it has its own access within the garden, you live in the main house, and Meath County Council is notified 14 days before work starts. The 33 m² 1 Bed Granny Flat and the 45 m² 1 or 2 Bed Granny Flat fit the band; the 48 m² 2 Bed Granny Flat needs standard permission, which we handle. The exemption runs until 31 December 2030, and we check your site free of charge.

Which council do I notify for a garden home in Enfield?+

Enfield is in the Meath County Council area, so that is the planning authority you notify. The Class 3A notification must reach the council at least 14 days before work starts, giving the location and Eircode of your property. Email penquiries@meathcoco.ie (confirm the address by phone first). Meath County Council publishes its own notification form, linked on this page, and we prepare and file it for you as part of every exempt build. It is separate from the building control Commencement Notice, which goes on BCMS because a garden home is a new dwelling.

How much does a garden home cost in Enfield?+

Our prices are fixed nationwide, so a build in Enfield costs the same as anywhere else: €93,900 (€106,577 incl. 13.5% VAT) for the 33 m² 1 Bed Granny Flat, €126,500 (€143,578 incl. 13.5% VAT) for the 45 m² 1 or 2 Bed Granny Flat and €134,500 (€152,658 incl. 13.5% VAT) for the 48 m² 2 Bed Granny Flat (+ VAT @ 13.5%), including design, build and full project management. The 25 m² Garden Studio, a garden room rather than a home, is €69,000 + VAT @ 13.5% (€78,315 incl. 13.5% VAT). Prices exclude site works, connections and professional fees. We quote those after your free site visit in Enfield.

How long does a garden home build take in Enfield?+

Once your foundations are ready, the on-site structural build takes 5–10 days. Primestructures’ own crew builds every home, with 10 years of ICF construction behind them. Design, planning and connections come before that: for an exempt size, the 14-day notification to Meath County Council and the building control Commencement Notice have to go in before work starts, and a larger size needs planning permission first. We give you a full timeline at your free site visit.
