Corten steel-clad extension in Hackney

A contemporary three-storey glass and steel addition transforms this Victorian home

In 2016 entrepreneur Andrew Bredon got the chance to tackle his dream renovation project, adding an extension with striking Corten steel cladding to a period property.

‘I’d been hunting for the right house for several years,’ he says. ‘Few places with the bones of what I wanted came up for sale in east London.’

Andrew, 43, and his wife Lotti Benardout, 36, who is a professional musician, focused on Georgian and Victorian properties as they had the big rooms and high ceilings the couple were after. They finally found a three-bed Victorian semi-detached villa in Hackney, east London, which they bought for £2.4 million.

‘When this house came on the market, we were attracted by what we could do with it,’ explains Andrew. ‘Though it was in good condition, it hadn’t been updated for around 20 years.’

The four-storey building was divided into two flats. The couple planned to turn into a single home and update it with an elegant extension. By converting the two apartments into one house, they would pay just 5% VAT on materials and labour, rather than the standard 20%.

Andrew set about tracking down the right architecture practice for the project. ‘I wanted to use a local firm, and found DeDraft via Pinterest,’ he says. ‘I was fairly set on the aesthetics, but needed an architect who could take the lead on the technical aspects.’

The couple had a series of must-have items on their wishlist. As well as the striking Corten steel cladding, they wanted a new double-height space at the back of the house. ‘The ground-floor kitchen was cut off from the garden, so Andrew and Lotti wanted to create a better connection from inside the house to the outside,’ explains Grant Straghan, a director at the practice.

Andrew and Grant developed the plans together, deciding to rebuild the outrigger rather than extending further into the back garden. The lower-ground floor was excavated to allow for a sunken patio at the rear, then the ground floor was partly cut away to create a double-height space.

The Corten steel cladding (supplied by Eltheringtons and installed by Carter Cladding) makes a clear distinction between the new-build and the original London stock brickwork. ‘From a planning perspective, there was a precedent,’ says Andrew. ‘Our next-door neighbour had done something fairly similar, so I wasn’t too worried.’

But it wasn’t all plain sailing. ‘Hackney council is more progressive than some boroughs, but the process is still somewhat subjective,’ he says. A few design tweaks were required before the couple obtained consent. ‘We had to introduce an extra column in the extension to break up the expanse of glazing,’ says Grant.

Things weren’t made any easier when the relationship between the couple and their builder started to sour. ‘Once construction began there was a lot of underpinning to do, which made for quite a slow build,’ explains Grant.

‘Structurally, the project was complex because the back of the house was being rebuilt and they were making level changes. I think the builder underpriced the job initially, which came back to bite him later when he realised how involved it really was.’

The contractor walked off the site with six months to go, leaving Andrew and Lotti high and dry. No other firms wanted to take on the partially finished work. But Andrew didn’t let that deter him – he became the project manager and hired individual trades to complete the build.

The couple were also hands-on when it came to procuring materials, even travelling to Belgium to select the marble for the kitchen island. After a challenging 18 months, the project, which cost £600,000, was finished in time for the first national lockdown. ‘The house has massively enhanced our lives,’ says Andrew.

‘I’m a real foodie, so I love the kitchen. It’s a fantastic space in which to be a messy chef.’ He also acknowledges the lessons that were learnt along the way. ‘I’d do a lot more due diligence on the building firm next time,’ he says. ‘If you’re going to spend 12 months working with someone, you’ve got to have the confidence they’ll deliver what you want.’

Despite the problems, Andrew has not been deterred from taking on another scheme in the future. ‘I can imagine doing another build in the next few years,’ he says. ‘My next goal is to find a patch of land and build a house from scratch.’
