Street viewFrom above
Exterior read
This mid-century style suburban home features a front porch extension, a large paved driveway, and an attached side structure. Situated in an established residential area with good garden depth, it provides a functional layout well-suited for family living or investment.
▲ What stands out
Large paved front driveway providing off-street parking for multiple vehicles.
Enclosed front porch extension offers extra security and improved thermal insulation at the main entrance.
Substantial, private rear garden visible on satellite view offers strong potential for future extensions.
Low-maintenance front apron and durable pebble-dash/rendered facade.
Attached side garage/structure provides valuable utility, storage, or conversion potential.
▼ Watch for
Proximity of a large mature tree near the front boundary presents potential root encroachment and gutter clearance concerns.
Shared party wall construction inherent to terraced/semi-detached layouts reduces acoustic privacy.
Flat roof sections over the porch and side structure are prone to standing water and require periodic maintenance.
Older solid/cavity wall construction may require retrofitted wall insulation to improve energy efficiency ratings.
Extensive front paving reduces natural surface water permeability during heavy rainfall.

Fair value is anchored on 3 recent same-street sales (adjusted to today's prices), cross-checked against homes of this size, type, energy rating and area; the asking is 5% above its midpoint. Homes in Ireland often sell over asking in strong areas, so the top of the range is fair value, not a ceiling. A guide for your negotiation, not a valuation — the right bid also depends on how much you want it and what you can borrow.
