We partner hand-in-hand with local authorities to ensure compliance with all current legislation. We always closely work with you on your ideas to draw up unique loft conversions plans for you. London homes often have a limited amount of space to expand
to, so going upwards is the smart way to gain more space. We only use high quality materials so you can be sure of the first-class result and complete satisfaction. It does not matter whether your attic is large or small – we can provide innovative solutions to maximise the usability of your new rooms. Our highly-skilled joiners can work wonders during home renovation and we always aim to exceed the expectations of our clients, making the most of lighting, materials and taking into account the height of your roof to fully utilize the available space. A quick look through our gallery will assure you that Diamond Construction’s home renovations are the most affordable way to add a stunning new room to your house.
