Notes on Buying a Listed Conversion

Foundry Quarter's warehouses are the most rewarding buildings we sell and the ones that generate the most questions after an offer is accepted. Most of the difficulty is procedural rather than physical.

A listing covers the whole building

Listing is not confined to the elevation. It applies to the structure, and inside a conversion that usually means the trusses, the cast-iron columns, the original openings and often the internal brick face. Work that would be permitted development in an ordinary house needs consent here, including work that is invisible from the street.

This is manageable. What causes real trouble is discovering that a previous owner did work without consent: the liability transfers with the building, and it does not expire. Ask for consents, and ask to see them rather than be told about them.

The conversion is a building of its own age

The shell may be 1911, but the floors, services and insulation date from the year of conversion. A 2019 conversion behaves like a 2019 building. A 2004 one may not have had the same standards applied. Read the completion certificate and the energy assessment together — between them they tell you more than the survey will.

Volume is the thing you are buying

Six-metre ceilings are the reason to be here, and they are also the reason to think carefully about heating, sound and how you will change a lightbulb. Well-converted buildings answer this with underfloor heating and acoustic separation at the mezzanine. Poorly converted ones ask you to heat the roof.

Go back a second time in the evening. A north-lit warehouse changes completely once the daylight has gone, and it is a fair test of whether you want to live in it.
