Atmospheric illustration of L'Union, in the north-eastern suburbs of Toulouse, in Haute-Garonne.
In L'Union, the average price of apartments stands at 3 199 €/m², based on sales actually registered in DVF data, the French notarised sales database. Houses, which dominate the housing stock, trade at a similar level, on average around 3 114 €/m². These values, among the highest in Toulouse's north-eastern ring, reflect the affluent residential character of the municipality, sought after for its quiet, tree-lined neighbourhoods of detached houses. Plot size, the condition of the property, its energy performance and proximity to shops and the ring road make prices vary from one area to another. Strong demand from families settling for the long term tightens a market with limited supply. These notarial figures give a municipal benchmark; a reliable valuation then relies on comparable properties, assessed case by case.

L'Union confirms its status as an affluent residential municipality in north-eastern Toulouse. Demand, driven by families and professionals from the metropolitan area, focuses on houses in residential neighbourhoods, in an area where supply remains limited. This relative scarcity of properties, combined with the proximity of Toulouse and the ring road, supports high prices and short selling times for well-located homes.
The condition of the property, plot size and energy performance account for most price gaps: a renovated house with a proper energy rating sells without difficulty, while an energy-inefficient property or one needing refurbishment suffers a discount. The closeness in value between houses and apartments makes location and quality decisive. Dependence on the Toulouse job market remains the main factor of sensitivity for the L'Union market.
L'Union sits above its inner-ring neighbours such as Launaguet, at a level close to Balma, another affluent residential municipality, and just below Toulouse.
L'Union is a recent municipality on the scale of Toulouse's history: it was created in the 19th century from territory detached from neighbouring municipalities, hence its name, which evokes the bringing together of these parcels of land. Long rural, it remained a small farming village on the outskirts of Toulouse until the mid-20th century.
The post-war expansion of the Toulouse conurbation profoundly transformed the municipality. Located in the inner north-eastern ring, right next to the city, L'Union filled with detached housing estates and became a residential suburb sought after by families.
Over the decades, the municipality has strengthened its affluent residential profile, with neighbourhoods of detached houses, public amenities, shops and quick access to the Toulouse ring road. It is today one of the sought-after addresses in north-eastern Toulouse, valued for its quiet and its proximity to the employment areas of the metropolitan area.
L'Union has around 12 600 inhabitants and ranks among the affluent residential municipalities of Toulouse's inner north-eastern ring. The property market is dominated by the detached house, in quiet, tree-lined residential neighbourhoods that mainly attract families and professionals working in the metropolitan area. Apartments are available, particularly in more recent developments, but remain a minority. The immediate proximity of Toulouse, access to the ring road, shops and the reputation of its schools sustain strong demand in a stable and sought-after market, where quality properties sell quickly.
The average price of apartments in L'Union is 3 199 €/m², based on DVF transactions completed before notaries. Houses trade at a similar level, on average around 3 114 €/m². Plot size, the condition of the property, its energy performance and its location within the municipality explain most of the gaps. In a sought-after market, a reliable valuation relies on comparable sales rather than on the municipal average alone.
L'Union benefits from an affluent residential profile and a favourable location in Toulouse's inner north-eastern ring. Its quiet, tree-lined neighbourhoods of detached houses, its shops, its amenities and its quick access to the ring road make it a popular address with families and professionals in the metropolitan area. This appeal, combined with a limited supply of houses, supports prices among the highest on the north-eastern outskirts of Toulouse.
The housing stock in L'Union consists overwhelmingly of houses, in residential estates. Apartments are available, mostly in more recent developments, but remain a minority. A buyer looking for a detached house with a garden will find a highly valued but sought-after supply, while someone seeking an apartment will have a narrower choice. House and apartment prices are close here, which makes the type of property less decisive than elsewhere.
The municipality borders Toulouse to the north-east and has direct access to the ring road, as well as public transport links to the city centre and employment areas. This proximity is one of the main drivers of its residential appeal. It allows workers in the metropolitan area to live in a quiet suburban setting while staying a few minutes from Toulouse's employment areas and amenities.
The L'Union market is regarded as stable and sought after, driven by steady demand from families wishing to settle for the long term. The limited supply of houses in the residential neighbourhoods supports prices and shortens selling times for quality properties. Gaps arise mainly from the condition of the property, plot size and energy performance. A renovated home with a good energy performance rating clearly stands out in this market.
