While so many of us yearn for a sea view, the reality is more often somewhat more mundane that we expect.
Depicted in the estate agent's brochure photo, the typical sea view too often consists of three horizonal lines - the land, the sea, the sky - laid out in a sort of grey/blue grey/grey sideways tricolour. A bare modernist tableau.
Because too often the reality is that the expanse of sea outside your window can be, well… boring after a bit.
Unless there's plenty going on out there that is.
The advantage of a rooftop sea view which overlooks Dun Laoghaire harbour is that there's always plenty of interesting sea-going traffic. From giant ferries, to container ships criss-crossing the skyline. From power boats to pleasure-trip vessels, to fishing boats, wind-surfers and flotillas of brightly coloured elegant yachts and dinghies.
Because Dun Laoghaire harbour and the expanses of water outside it to the horizon is quite possibly Ireland's very busiest and most colourful sea view. The town has a clutch of top yacht and sailing clubs and it's a daytrip and summer festival town. The water is continuously filled with sails.
The best rooms in the rooftop penthouse apartment located at The Pierre apartment scheme in Dun Laoghaire, look across the Victorian rooftops of the old resort town and back and forth across this busy and colourful sea vista.
You'll never get bored sitting around up here.
Until a few years ago The Pierre was a long-serving resort hotel that dated from the golden age of 19th-century seaside tourism and one of Dun Laoghaire's best-known institutions. During the Celtic Tiger years the last owners and operators, a family based in the west of Ireland, sold it on to developers for conversion to luxury apartments.
The old Pierre is still remembered fondly by locals as one of those unique institutions - a family run hotel business with a penchant for looking after its guests to the highest degree.
So much so, that like the seaside resort hotels of old, the Pierre became a permanent residence for many retired people who fell in love with it, the views, the town and the friendly service provided within the hotel's bar, dining and function facilities.
Not surprisingly the permanent residents tended to room upstairs in the top suites.
The Hotel Pierre's ground-floor bar was attended by a rugged alternative-minded yachting set, English, Welsh and Scottish rugby tourists and locals who flooded in to be entertained and regaled by the wit of a particularly well-known and dapper bar man.
Thankfully the imposing main building was not demolished for the redevelopment and today the Pierre of old is once again a permanent home - for the residents of just 18 apartments.
These apartments come with underground parking and a "car elevator" to take the vehicles down to a secure environment.
But as expected, the best views are in the penthouse - currently on offer for sale through Douglas Newman Good's Dun Laoghaire office.
From number 17 you can scan across over the rooftops from Killiney Hill on one side, to the 40ft at Sandycove on the other.
Measuring almost 1,000 sq ft, the size of a three-bed semi, it has an entrance hall with oak timber floor and a skylight overhead. There's a living room/kitchen with hardwood oak flooring which comes with contemporary designer units as well as a built-in fridge/freezer, dishwasher, overn, hob, coffee machine and microwave.
Sliding doors lead out to a balcony which is perfect for entertaining and maximising the vista.
There's a storage room which could double as a pantry for holding food or as a cloakroom and there are two bedrooms, one of which has an ensuite and a walk-in wardrobe.
The main bathroom is kitted out in Villeroy and Boch and there's underfloor heating and LED lighting.
Situated on Victoria Terrace, the Pierre complex is right opposite the East pier from which the old hotel would take its lunch diners and bar sippers.
So you can walk out your front door and straight down the pier.
It's also located just off the main thoroughfare of Dun Laoghaire which has every amenity on your doorstep including cafes, shops, restaurants and famous pubs. There are schools and churches of all denominations and Dun Laoghaire is connected to Dublin via the the DART & QBC within five-minute walking distance. The Rock Road, N11, M11 and M50 are also close by.
In recent years Dun Laoghaire has become home to a number of lively music and arts events festivals including a world cultures event and the annual Ukulele Hooley which brings players of the tiny instrument here from all over the world. At weekends the people's park becomes a popular food market.
