Two detached modern houses in one of the southside's most sought-after suburbs come with a high spec and are in walk-in condition

Marlborough Park/€2.8m: A detached double-fronted house at 7 Marlborough Park, Glenageary, Co Dublin, has been completely rebuilt and extended with an emphasis on flowing spaces and light both by day and by night. Called Colimor, it is for auction through Lisney on March 14th with an AMV of €2.8 million.

Designed by architect Colie O'Donoghue (after whom it is named), the house is a perfect party place as well as a family home with soaring double height atriums, underfloor heating, programmable lighting and sound throughout. It has a nice mix of marble and walnut flooring.

The open-plan kitchen and dining area, which spans the back of the house, is a superb space, calm and bright with a Danish fitted kitchen, a wall of storage and utility room behind a curving damson-painted wall. Marble flags run through to the seating and dining area with its wall-mounted steel fireplace at one end, comfortable seating bay and extensive windows and ceiling lights.

The whole house has lighting features of every sort and, in the open-plan kitchen and dining area, it is Japanese glass wall panels which light up and floor spots which change colour. This space opens onto a wide decking area overlooking the back garden.

Two balconies look into this space from the landing, while the drawingroom also opens off it. The double height hall has a melodious water feature, a cloakroom and family room off it while the eye is drawn up to another gallery.

Upstairs there are four bedrooms, two en suite, and a main bathroom. The big surprise here is the main bedroom suite. This is like a private duplex within the house; there is a bedroom and sittingroom, and a stunning bathroom built up into the eaves of the house, the whole thing combining to make a perfect retreat for parents.

Decorated in soft white with cubes of blue glass set into the upper wall, the bedroom has a curving limestone staircase up to the large bathroom complete with ample wardrobes, a huge window with panel opening out to form a small balcony, round Jacuzzi bath placed for the view of the sky, and large shower and steam unit.

The sittingroom opens off the bedroom and has a balcony to the dining area below and built-in speakers.

The front garden has been paved and gravelled with car-parking space, steps to a lower level and Japanese planting. The back garden is secluded with a patio area at one end and the house is designed to open into these spaces with many sliding doors.

Silchester Downs/€2.8m: Built 10 years ago, Andromeda, Silchester Downs, Glenageary, Co Dublin, is one of five detached houses in a gated development off mature and leafy Silchester Road.

It will be auctioned on March 22 with Lisney quoting an AMV of €2.8m. With four reception rooms and four bedrooms, it has a roomy floor area of 236sq m (2,540sq ft).

It is imaginatively geared for family living with small touches such as the walk-in shelved room off the main bedroom which appears worth its weight in gold.

Standing in the hall, floored in double width maple, there is a sense of largesse, and your eye is drawn to the main rooms opening off, and to the galleried landing above.

To the right is a large attractive drawing room with dual-aspect views from its bay windows. There is an elegant Portland stone fireplace with stainless steel inset and space for three large couches in a colour scheme of cream with soft rose.

A front facing study has a bay window and cast iron fireplace with coal effect fire. An open plan living area incorporates kitchen and breakfast area with, again, lots of space.

The kitchen has a gas fired Stanley stove, integrated equipment, Shaker-style units painted yellow and is floored in aged marble.

The dining section is roomy enough for a large venerable refectory table and dresser.

Keep walking and you arrive at the fourth reception room, initially hidden from view, tucked behind the main living area, its cosiness and warmth explaining its place as a favourite family room.

There is a utility room, guest toilet and garage with internal access.

Two of the four bedrooms have en suite shower rooms, all bedrooms have fitted wardrobes, the main bedroom's walk in feature is designed and shelved for maximum efficiency. There is a family bathroom.

The cobblelock forecourt provides parking, and there are two side entrances.

A deep rear patio opens out to a lawn with tree house at the side.

The patio continues round to a south west facing sun spot at the side of the house, with a raised gravel area and easy seating.
