Grand Designs: House of the Year (2015- )

The search for the House of the Year 2025 reaches its finale, as Kevin McCloud, architect Damion Burrows and conservation architect Natasha Huq visit homes that have been dramatically transformed through rescue, re-invention or bold re-imagining. On the Isle of Wight, barns on the brink of collapse are saved and reborn as a luminous retreat, their battered shells now glowing with life. In London, a 1960s townhouse is stripped back, rebuilt and transformed into a striking example of high-end brutalism, the height of architectural sophistication in its day and re-imagined for modern family life. In Somerset, a draughty 1960s bungalow is swept away and replaced with a low-energy, loft-like house that almost disappears into the landscape. In Bath, a tired bungalow is completely overhauled, its flimsy frame wrapped in cedar shingles. In Suffolk, the very idea of what a house can be is completely transformed, where one home becomes four buildings - sleeping, living, working and utility - in a radical feat of architectural imagination. And finally, after finding out which of these incredible transformations has been shortlisted, the winner of the RIBA House of the Year 2025 is crowned.
