A set of profiles for constructing a terrace canopy comprising a beam (3; 5) extending in a longitudinal direction and having a top side, a bottom side, an inner side and an outer side, wherein a height direction of the beam extends between the top side and the bottom side and a width direction of the beam extends between the inner side and the outer side, and wherein the set comprises: - a beam profile having an upright inner side wall and a first connection means , - a first spacer profile provided with a second connection means and a third connection means ; - a second spacer profile different from the first spacer profile and provided with a second connection means and a fourth connection means (451; 490), the second connection means of the first space profile and the second spacer profile being identical; - a first beam-finishing profile ; and - a second beam-finishing profile , wherein a first beam can be constructed of at least the beam profile , the first spacer profile and the first beam-finishing profile so that the first spacer profile is attached to the beam profile by the first and second connection means and the first beam-finishing profile is connected to the first spacer profile by the third connection means , wherein a second beam can be constructed of at least the beam profile , the second spacer profile and the second beam-finishing profile so that the second spacer profile is attached to the beam profile by the first and second connection means and the second beam-finishing profile is connected to the second spacer profile by the fourth connection means (451; 490), characterised in that the first beam-finishing profile has an outwardly facing surface located at a first distance (d1) from said upright inner side wall and the second beam-finishing profile has an outwardly facing surface located at a second distance (d2) from said upright inner side wall, said first distance and said second being measured in a direction parallel to the width direction of the beam, wherein the first distance and the second distance are different. - a beam profile having an upright inner side wall and a first connection means , - a first spacer profile provided with a second connection means and a third connection means ; - a second spacer profile different from the first spacer profile and provided with a second connection means and a fourth connection means (451; 490), the second connection means of the first space profile and the second spacer profile being identical; - a first beam-finishing profile ; and - a second beam-finishing profile , wherein a first beam can be constructed of at least the beam profile , the first spacer profile and the first beam-finishing profile so that the first spacer profile is attached to the beam profile by the first and second connection means and the first beam-finishing profile is connected to the first spacer profile by the third connection means , wherein a second beam can be constructed of at least the beam profile , the second spacer profile and the second beam-finishing profile so that the second spacer profile is attached to the beam profile by the first and second connection means and the second beam-finishing profile is connected to the second spacer profile by the fourth connection means (451; 490), characterised in that the first beam-finishing profile has an outwardly facing surface located at a first distance (d1) from said upright inner side wall and the second beam-finishing profile has an outwardly facing surface located at a second distance (d2) from said upright inner side wall, said first distance and said second being measured in a direction parallel to the width direction of the beam, wherein the first distance and the second distance are different. <EOS>
