‘Best extension to an existing home’
LABC Building Excellence Award

Award-winning refurbishments

JNJ Building Solutions is proud to have received a highly commended award in the ‘Best Extension or Alteration to an Existing Home’ category at the LABC Building Excellence Awards. The calibre of this achievement is evidenced by the number of entries:


completed projects were reviewed by LABC that year


were shortlisted for the awards


made the final shortlist and were invited to the awards ceremony

The project that earned us our highly commended status was a complex ground floor rear extension and full refurbishment of Herne Hill. Our clients, Anna and Steve, had lived in the property for more than 40 years and wanted to expand and modernise their home. The end result is an outstanding finish that exceeded their expectations and impressed the award judges.
