Build Me builds extensions, conversions and full renovations in Malahide and across north County Dublin. A period home by the village, a 1980s estate towards the estuary or a high-spec build on Sea Road, we'll come out, look at yours and give you a straight quote.
In the estates, families want more room without moving. Near the village, they want an older house brought up to date. These are the jobs we're asked for most. Prices are starting points.
From €40,000
From the family semis in Seabury and Chalfont to the larger detached homes near the village, a well-planned extension changes how a home works day to day. We pay close attention to materials so the new work sits well with the house.

In estates like Gainsborough, Seabury and Robswall, where the footprint is fixed but the family has grown, the attic is often the most practical place for a bedroom or office. We check the roof structure and headroom before you commit.

From €18,000
Many 1980s and 90s homes in Malahide's larger estates have integral garages used for storage, not cars. A bedroom, home office or utility room there is one of the more cost-effective ways to add a room.

From €25,000
Many homes near the village were built to last but haven't been touched inside in decades. Whether it's a 1930s detached or a 1980s semi taken back to the walls, we rewire, replumb and finish it to a high standard.

Built from the 1920s to the 1960s, solid but often with layouts that don't suit family life now. A rear extension or a full internal reconfiguration opens them up without changing their character from the street.
On roads like Yellow Walls Road and Sea Road the standard of finish expected is higher and the detail work matters more. Near the estuary or on a road with mature trees, there can be extra planning considerations too.
Family semis and detached homes with integral garages and roofs that often suit a conversion. A rear kitchen extension, an attic bedroom or a garage conversion are the usual ways to add room without moving.
Malahide is in the Fingal County Council area. Fingal is fairly straightforward for standard rear extensions under exempted development. Full applications are refused more often here: Fingal refused 23 of 152 extension applications, an 85% grant rate, against 96% in Dún Laoghaire-Rathdown.

Where we look more closely before any money goes on architects or drawings.
A rear extension is exempt up to 45 m² in total, counting every extension since 1964, with at least 25 m² of garden left and no higher than the house. If an earlier owner added 20 m², you have 25 m² left. A Section 5 declaration (€80) from Fingal confirms it in writing.
Planning permission rules 2026A single-storey rear extension takes about 12 to 16 weeks on site, and most can start without a planning application.

Yes. We work throughout Malahide and the wider north Dublin area, including Kinsealy, Portmarnock, Swords and Donabate. We're based in Stillorgan but travel north regularly and have worked on a number of projects in Malahide and the surrounding villages. The site visit and quote are free.
Malahide falls under Fingal County Council rather than Dublin City Council, and the exempted development rules are the national ones. A single-storey rear extension of up to 45 m² in total, leaving at least 25 m² of garden and no higher than the house, usually doesn't need a planning application. If your home is close to the castle demesne, near the estuary, a protected structure or in an area with landscape or heritage designations, different considerations can apply. We go through the planning position with you at the quoting stage.
House extensions start from about €40,000. As a guide from our extension calculator, a 20 m² single-storey rear extension in Dublin costs €54,000 to €69,000. Attic conversions start from about €22,000, garage conversions from €18,000 and home renovations from €25,000.

Yes, and it's work we do regularly. The older homes on roads like Yellow Walls Road, Sea Road and around the castle are well built but often have layouts that don't suit how families live now. A rear extension or a full internal reconfiguration can change how the house works without changing its character from the outside. We take care with materials and detailing, because the finish expected here is high.
For the 1980s and 90s semis and detached homes in estates like Seabury, Gainsborough and Chalfont, the most common project is a rear extension that opens up the kitchen into a proper kitchen, dining and living space. Attic conversions to add a fourth bedroom or a home office are also very popular with families who don't want to move but have outgrown the space they have.
Usually, yes. Many 1980s and 90s homes in Malahide's estates have integral garages used for storage. Converting one into a bedroom, home office or utility room is one of the more cost-effective ways to add a room, usually without planning permission, and it causes little disruption to the rest of the house. Garage conversions start from about €18,000 and take 6 to 8 weeks on site for an office or bedroom.
A single-storey rear extension typically takes 12 to 16 weeks on site, and a two-storey extension 16 to 20 weeks. A full home renovation varies with the scope, but most run 10 to 20 weeks. We give you a clear timeline before work starts and send daily photo updates so you always know what's happening on site.
