Local Housing Profiles

Homes in Donnybrook and how we insulate them

Donnybrook is a historic south Dublin urban village located along the River Dodder, featuring an impressive blend of architectural styles. The built landscape includes Georgian terraces along Morehampton Road, Victorian red-brick villas, Edwardian family residences around Belmont Avenue and Marlborough Road, post-war apartment complexes, and discrete 1970s mews dwellings [CONFIRM housing stock].

Many solid brick period homes in Donnybrook have substantial uninsulated exterior walls that conduct heat away rapidly during winter. Because 9-inch solid brickwork has poor thermal resistance (typical U-values around 2.1 W/m²K), heating these properties requires excessive energy consumption, while perimeter walls and returns remain uncomfortably cold.

Because the streetscapes of Donnybrook are strictly protected, front facades must generally be preserved in their original brick or stone finish. Our specialized retrofit approach focuses on externally wrapping the substantial two-storey and three-storey rear elevations and garden returns in high-density Baumit EPS insulation board. This eliminates massive heat loss from the rear while leaving front facades pristine. On non-protected mid-century homes and townhouses, we install full exterior wraps across all elevations.

Planning & Compliance

Conservation areas and planning in Donnybrook

Planning governance in Donnybrook is administered by Dublin City Council. The suburb encompasses several designated conservation areas, including the Morehampton Road Architectural Conservation Area (ACA) and Marlborough Road environs. Furthermore, numerous historic properties are catalogued on the Dublin City Record of Protected Structures (RPS).

Under Dublin City Council regulations, altering front-facing brick, stone, or decorative plasterwork on Protected Structures or within ACAs requires formal planning permission. However, insulating rear elevations and side returns frequently qualifies under exempted development provisions if the works are not visible from the public road and do not compromise historic building elements.

Isotherm assesses every Donnybrook property against Dublin City Council planning registers during our pre-contract survey. We assist homeowners with Section 5 exemption filings and coordinate with conservation professionals where required. Learn more in our detailed guide on planning permission for external insulation.

Common Questions

Frequently asked questions in Donnybrook

Can period red-brick houses in Donnybrook be externally insulated?

Yes, using an engineered rear-wrap strategy. We preserve the protected front red brick facade while wrapping the large rear brick return and back elevations in Baumit external insulation, where the vast majority of heat loss occurs.

How do you handle services and downpipes on Donnybrook period homes?

Our direct crews unclip soil vent pipes, rainwater downpipes, and electrical cables, mounting them onto certified thermal break standoffs to prevent cold bridging across the new insulation layer.

Will external insulation stop condensation on cold bedroom walls in Donnybrook?

Yes. By placing the insulation on the exterior of the solid brick walls, the masonry core stays warm, raising internal surface temperatures above the dew point and stopping condensation permanently.
