Home Extensions Islington
Create the Space Your Islington Home Deserves
Islington is a place of contrast – elegant Georgian terraces, lively modern apartments, and thriving high streets like Upper Street and Essex Road. But as much as the area offers character and charm, many homes here were not designed for today’s lifestyle. Kitchens can feel cramped, hallways narrow, and living spaces cut off from the garden.
At Reltic Extend, we specialise in house extensions in Islington that unlock the true potential of your property. Whether you’re dreaming of a sleek rear extension that floods your home with natural light, or a clever side-return build that transforms unused space into a modern kitchen-diner, our designs are made to fit the way you live today.
