We investigate the nature of 14 embedded clusters (ECs) related to a group of four H  ii  regions, Sh2‐235, Sh2‐233, Sh2‐232 and Sh2‐231, in the giant molecular cloud G174 + 2.5. Projected towards the Galactic anticentre, these objects are possible examples of the  collect‐and‐collapse  scenario. We derive astrophysical parameters ( age, reddening, distance, core and cluster radii ) for the ECs and investigate the relationship between these parameters. Parameters are derived with field‐star‐decontaminated 2MASS colour–magnitude diagrams (CMDs) and stellar radial density profiles. The CMDs of these young clusters are characterized by a poorly populated main sequence and a significant number of pre‐main‐sequence stars, affected by differential reddening. The ECs are KKC 11, FSR 784, Sh2‐235 East2, Sh2‐235 Cluster, Sh2‐233 SE Cluster, BDSB 73, Sh2‐235B Cluster, BDSB 72, BDSB 71, Sh2‐232 IR Cluster, PCS 2, and the newly found clusters CBB 1 and CBB 2. We were able to derive fundamental parameters for all ECs in the sample. Structural parameters are derived for FSR 784, Sh2‐235 Cluster and Sh2‐235 East2.
