A gradual return of housing to Edinburgh's New Town is gathering pace with the submission of plans to convert an office block at 57 Henderson Row by way of a double mansard roof.

Royal London, with CDA Architects, proposes to convert the building into 64 build-to-rent apartments, hot on the heels of a residential development to the immediate south at Henderson Place.

Built in 1991 as the headquarters for financial services firm Royal London the block occupies a former tram depot, the Victorian facade of which has been retained and incorporated into the development. Key to the transformation will be the removal of an existing mansard roof, used to conceal services, which a matching double-height extension will replace.

Dormer windows to the south and east will be inserted to accommodate this new role and displaced plant equipment will be relocated to the basement car park.

Outlining the need to push upwards, CDA wrote: "Extending the existing roof form up by one floor provides an additional storey of accommodation. The visual impact of the additional storey is lessened because it is formed as an extension of the existing roof profile. The existing main mansard roof and lower mansard roofs will be reclad to match the new roof storey."

Elevations will otherwise remain largely unchanged, save for a light clean, with decorative metalwork repaired and repainted.

Hideous! I'd rather the building was demolished rather than this pathetic vandalism!!

Self-sabotage of what was a really well considered conversion of the depot back in the 90s.

#4 Totally. Would obliterate a nicely proportioned and detailed mansard roof with a vast, overbearing grey slab.

The proportions feel awkward and top-heavy. The roof dominates the composition and undermines the original building’s hierarchy. Extending the stonework up a storey before introducing the roof would have created a more balanced and elegant solution. Their solution is dreadful.
