House Extension Tallaght
House Extension Tallaght
If your home in Tallaght is running out of room, an extension adds the space where you actually need it, without the cost and upheaval of moving. A bigger kitchen, a dining space, a family room or a downstairs bedroom.
Tallaght housing is mostly 1970s and 1980s, and the gardens are generally deep. Where modern estate houses are constrained by the space left behind them, Tallaght houses usually are not, so the conversation is more about what you want than what the site permits.
House Extensions in Tallaght
Tallaght housing is mostly 1970s and 1980s, and one feature of that era works strongly in your favour: the gardens are generally deep. Where modern estate houses are constrained by the space left behind them, Tallaght houses usually are not.
That means the conversation here is more often about what you want than about what the site will permit.
Deep Gardens Mean Real Scope
A ground-floor rear extension can often be built as exempted development in Ireland, subject to conditions on floor area and on the private open space that must remain behind the house.
On a typical Tallaght garden the open space condition rarely bites first, so the floor area limit becomes the practical ceiling, and for many families that is enough to get the kitchen and dining space they actually want without any application at all.
Anything a previous owner added counts towards the allowance, so we check the history of the house as well as measuring it.
Extending a 1970s or 1980s House
Housing of this era was generally built with cavity walls and conventional foundations, which makes tying a new extension into the existing structure reasonably predictable.
What we check is the condition of the original rear wall where it is coming out, the position of drainage, and whether the existing roof is trussed, which matters if you are thinking about going up rather than just out. Thermal performance is usually the weak point in houses of this age, and if the rear is open anyway it is the right moment to improve it.
If your extension is part of a wider home upgrade, we also provide bathroom renovations in Tallaght. Discuss the bathroom scope at the same survey so it can be included in the overall budget and programme.
Planning Permission in Tallaght
Tallaght is in the South Dublin County Council area, and we deal with them on your behalf where an application is needed.
Because Tallaght gardens tend to be generous, more of our work here stays within the exemption than in the denser parts of Dublin. Where a design goes beyond it, that is straightforward to handle, but it should be a decision made at the start rather than a discovery made later.
Building regulations apply either way, and the compliance paperwork matters at resale.
Open-Plan Kitchens in Tallaght
The most common Tallaght project is a rear extension that opens into the kitchen to create a single kitchen and dining space. Removing that rear wall is structural work needing a steel beam sized by an engineer, with the existing foundations checked before the design is fixed.
Because the gardens allow it, Tallaght extensions are often wider than the equivalent job elsewhere in Dublin, which usually means more steel rather than less. That is priced in from the start.

House Extension Tallaght FAQs
Do Tallaght houses have room to extend?
Usually yes, and more than most. The 1970s and 1980s housing here generally sits on deep gardens, so the private open space condition that constrains modern estate houses rarely bites first. For many families the floor area limit alone is enough to get the kitchen and dining space they want without any planning application.
Do I need planning permission in Tallaght?
Tallaght is under South Dublin County Council. More of our work here stays within the exemption than in denser parts of Dublin, because of the garden sizes. Where a design goes beyond it that is straightforward to handle, but it should be decided at the start rather than discovered later.
Does a previous extension count against what I can build?
Yes. The allowance applies to the house rather than to the owner, so anything added by a previous owner reduces what you can add now. We check the history of the house as well as measuring it.
Can I open the kitchen into the new extension?
Usually, and it is the most common project we build here. It is structural work needing a steel beam sized by an engineer. Because Tallaght gardens allow wider extensions than elsewhere in Dublin, that often means more steel rather than less, and we price it from the start.
