If you have even a little bit of space outside of your home your dreams of additional space inside of it and an elegant terrace in the garden, where you can organise a BBQ with your friends and family, can be turned into reality. With Diamond Construction team, quality and elegant house extensions in London are available to virtually everyone.

So far we have completed construction projects designed in modern style, where glass and metal are the most prominent, or in traditional version, with extensive use of wood, stone or bricks. Our belief is that every idea can be realised and every building can be extended as long as there is enough free space outside. At the same time we make sure that the house extensions we create harmoniously combine with existing structure and its surroundings.

Plan the additional space inside your home with Diamond Construction from London!
