The late architect Bruno Sacchi's medieval tower in Florence

Jane Sacchi recounts the experience of updating a twelfth-century tower in Italy, originally restored by her architect husband Bruno in the Seventies

Bruno's project for the Torre was innovative and ahead of its time in its solutions to the technical problems of a building of its age. It took three years to transform it into an exceptional family home, during which period Bruno often wandered about with a hammer and chisel picking plaster off the walls to expose the frescoes. He took time to consider each space and how the light falls at different times of day, making every angle, aperture and window a picture in itself. He created contemporary interiors that managed to contrast with and yet enhance the ancient setting. On the first floor of the tower, he discovered the frescoes with a cross-shape motif. It is here that, when faced with the technical challenge of delicate flooring unable to support more weight, he ingeniously designed the hanging staircase that is suspended from the beam above.

He used white Travertine alongside black slate for the floors, insisting on primary materials being used throughout, such as wood and steel, usually painted in his beloved orange minio - the anti-rust undercoat paint used in Tuscany and a signature note in many of his houses. 'Visual truth, nothing fake,' he would say. 'You cannot restore a medieval tower to its original condition - you would have only stone. So be honest with what you add.'

On the ground floor, an opening leads to the dining room, which features exposed, early fourteenth-century frescoes and Eames chairs with antique linen cushions.

On the ground floor, he designed a Travertine table for the kitchen inlaid with orange stucco and supported by steel girders. The dining-room table required such length that he simply used wooden planks resting on builders' trestles, surrounded by Eames chairs. The sitting room was furnished with blue Arflex 'Strips' sofas and ottomans set against the black-and-white flooring. The study still has the original Kartell stackable unit. In the four bedrooms, on the first, second and third floors, the medieval surroundings were punctuated by Artemide's 'Eclisse' bedside lights and Le Corbusier chairs.

In 1985, I returned to England and Bruno continued to live at the Torre. In his latter years, he amused himself by decorating the external doors and painting a 'Mondrian' on the loggia wall. This is where I have created the summer sitting room, a corner of shade and the perfect spot to watch the sunset over the distant Tuscan hills.

During the last years of his life, the Torre fell into a state of neglect. After his death in 2011, our children and I decided to restore it to the former glory of Bruno's original plan. The vast, arched, steel window frames throughout had rusted and had to be replaced, the entire property rewired, floors relaid and stucco work restored. Extensive interior redecoration included hanging new curtains and having the Eames chairs' cushions re-covered in antique linen. Sadly, the original 'Strips' sofas are no longer in production, so simple Ikea ones were found to recreate the same layout. Bruno's collection of African masks are where he hung them, on the stone wall of the tower.

The kitchen is almost exactly as he designed it, in white, black and orange. Astonishingly, it looks as contemporary now as it was in the Seventies and only required a coat of paint. The garden has been landscaped and a new entrance driveway created through the olive grove in order to maximise the impact of the tower on arrival.

The kitchen is as Bruno designed it, including his Travertine table inlaid with orange stucco.

In the 25 years that I have been away from Italy, the bureaucracy has not got any easier: I queued, I telephoned, I applied, I queued again, I went to endless offices that weren't open on that particular Tuesday. Despite the challenges, it has been a thoroughly satisfying two-year project made enjoyable by the team of extraordinarily talented and good-humoured craftsmen, all of whom had worked with Bruno and had great personal respect and affection for him.

It has given them, as well as us - Bruno's family and friends - immense pleasure to see his Torre and the legacy of his style live on.
