Designing homes in Ireland is about much more than creating a beautiful plan or an attractive elevation. Our climate places very real demands on buildings. High rainfall, wind exposure, humidity, salt air in coastal areas and changeable temperatures all influence how a home should be positioned, detailed and built.
At HD McKay, good residential design starts with understanding the site. A well-designed home should feel comfortable in the middle of winter as well as on a bright summer evening. That comfort is not achieved by accident. It comes from decisions made early in the design process, from orientation and shelter to materials, construction detailing and long-term durability.
Orientation, Shelter & Site Conditions
Successful homes respond first to their site. Orientation affects daylight, heat gain, and comfort. Shelter from prevailing winds improves energy efficiency and reduces Every successful home begins with its site. Orientation affects daylight, solar gain, views and comfort. Shelter influences how the house feels in daily use, how exposed entrances and outdoor spaces are, and how hard the building fabric has to work over time.
In Donegal and across the west of Ireland, many homes are built on beautiful but exposed sites. Views are often a major part of the brief, but they need to be balanced carefully with wind, rain and the practicalities of everyday living.
As Emma-Louise Hannigan, Registered Architect & Architectural Lead at HD McKay, explains:
“Clients are often focused initially on the view, the floor area or the overall appearance of the house, which is completely understandable. Our role is to bring that together with how the house will actually feel and perform. A window can frame a beautiful view, but we also need to think about whether it opens into the prevailing wind, how exposed the seals and junctions are, and whether the room will remain comfortable in poor weather.”
This does not mean avoiding glazing or turning a house away from its setting. It means designing with care. Entrances, frequently used doors, openable windows, patios and sheltered outdoor spaces all need to be considered in relation to the weather patterns of the site.
Designing Homes with Materials that Last
In the Irish climate, detailing matters just as much as material choice. A product may be suitable in principle, but if junctions are poorly resolved, or if weathering, drainage and ventilation are not properly considered, problems can appear over time.
Moisture ingress, thermal bridging, staining, premature weathering and condensation risks are often not caused by one single issue. They usually arise where design, specification and workmanship have not been fully coordinated.
“Ireland’s climate is unforgiving when detailing is treated as an afterthought,” says Emma-Louise. “The areas around windows, doors, roof junctions, thresholds and changes in material are often where buildings are most vulnerable. Good design is not just about what you see on the drawings. It is about making sure those junctions can be built properly and will continue to perform in real weather.”
For domestic clients, this is where professional architectural input adds real value. Durable design is not always about choosing the most expensive material. It is about choosing the right material for the location, using it correctly and making sure the detail supports its long-term performance.
Energy Efficiency Without Compromise
A comfortable, energy-efficient home starts with the basics: good orientation, a well-insulated envelope, thermal continuity, airtight construction and appropriate ventilation. Renewable technologies can play an important role, but they should not be used to compensate for poor design decisions.
Airtightness is particularly important. In simple terms, it is about reducing unwanted draughts and uncontrolled heat loss. However, airtightness must always be considered alongside ventilation. A home needs to retain heat, but it also needs a healthy supply of fresh air and effective moisture control.
“The best-performing homes tend to be the ones where the simple things are done very well,” Emma-Louise explains. “If insulation, airtightness, structure, ventilation and buildability are considered together from the outset, you are far less likely to end up with expensive compromises later. The aim is not just to achieve a rating on paper. The aim is to create a home that feels warm, dry, healthy and comfortable to live in.”
Energy efficiency should support good design, not restrict it. With careful planning, clients can still achieve generous light, strong views and attractive spaces while improving comfort and reducing running costs.
Designing for the Long Term
A home is a long-term investment. It should be designed not only for how a family lives now, but for how their needs may change over time.
Future-proofing can include flexible rooms, provision for home working, accessible layouts, sensible structural spans, potential future extensions, or allowing for future energy upgrades. These decisions are easiest and most cost-effective when they are considered at design stage.
“People’s lives change, and homes should be capable of adapting,” says Emma-Louise. “A good design should not feel fixed to one moment in time. It should have enough flexibility to support changing family needs, future technologies and evolving standards without major disruption.”
Ultimately, homes in Ireland need to do more than look good on completion day. They need to perform through winter storms, wet summers, changing family life and decades of use. That is where thoughtful design, robust detailing and a proper understanding of climate make all the difference.
