Who lives in Waterloo
Waterloo sits just south of Brussels, in Walloon Brabant beyond the city's ring road, a green, low-density town of detached houses, gardens and quiet residential streets. It has long drawn international and diplomatic families who want a house with space rather than a city-centre apartment, and who are happy to build daily life around the town and the car. The typical resident is a corporate or institutional expat with school-age children, often posted to Brussels for the European institutions or NATO, who values the family housing, the green surroundings and the international school on the doorstep. Those who prioritise space and schooling over a central, walkable base tend to settle here and in the neighbouring communes to the south. To see how Waterloo fits into the wider city, start with our directory of international schools in Brussels, and for the area context read our guide to the best areas to live in Brussels for expat families.
Schools in and near Waterloo
Education is a central reason families choose Waterloo. St John's International School, founded in 1964, sits in the town and has long been a leading choice for expat and local families in the Brussels area. It offers the full International Baccalaureate continuum, from the Primary Years Programme through to the Diploma, and is the only international school in Belgium with boarding, which suits families who travel or who want continuity for older pupils. Its presence is a large part of why the town reads as an international family base rather than a commuter suburb.
A drive north widens the field. The International School of Brussels in Watermael-Boitsfort offers an American-style education alongside the IB Diploma, and further British, bilingual and European options sit across the southern communes. For the full list with curricula, stages and admissions detail, use the Brussels schools directory, and read parent perspectives in our Brussels international school reviews. If you are not sure which curriculum or school suits your child, the school finder quiz will shortlist options based on your priorities.
Commute and catchment
Belgium does not operate strict residential catchments for international schools. Admission is by application rather than by postcode, so living in Waterloo does not guarantee a place at a local school, though proximity makes the daily run far shorter for St John's and the southern cluster. The town connects to Brussels mainly through the ring road and the main southern arteries, with a regional train line into the capital for those who prefer rail. Waterloo sits beyond the Brussels metro, so it leans car-dependent: most families drive, use school buses where offered, or combine train and tram for the run into the centre. Plan journey times around the morning and afternoon peaks, when the ring road toward central Brussels backs up.
Housing and cost of living
Housing in Waterloo is dominated by detached and semi-detached family houses with gardens, rather than apartments, set among green streets and parks. That low-density, leafy setting places it in the upper-mid to premium band of the Brussels area's family rental market, above central apartment districts for comparable space. When you add school fees and a car to family-home rent, Waterloo is a substantial budget, though residents consistently rate the space and the school access highly. Before committing, model the full picture, rent, schooling and transport, with our relocation cost calculator, set fees in context with our guide to primary international school fees in Brussels, and read the wider relocation guide for visas and setting-up logistics. Treat any specific rent figure you see as indicative, because the market moves, so verify current asking rents before you budget.
Family life
Daily life in Waterloo is built around green space and the international community. Parks, sports clubs and the nearby Forest of Soignes give families dedicated outdoor space, and weekend life often revolves around clubs, cycling and the surrounding countryside. The town centre provides everyday shopping, supermarkets, cafes, clinics and restaurants, so much of family life happens without a drive into Brussels. Healthcare access is good, with clinics in the town and major hospitals a manageable drive away, which matters for families with young children. The community is well-established and international, with a strong network of family-oriented activity tied to the schools. The main caveat is the position outside the Brussels-Capital region: the space and quiet come at the cost of a commute into the centre and reliance on the car.
