What we do

Projects in which we participated under supervision of:

Diamond Construction ltd

Unit 4, 245 Church Road

Mitcham CR4 3BH, London UK

House extension Basement extension

London W8

This project involved a house extension in order to increase the amount of space and light. This new, spacious, cosy place is now the perfect family space. We also added garden refurbishment and a bespoke kitchen to complete the package.

London SW10 9DD, UK

A typical Victorian house with its miniscule size and dark atmosphere that required more space to be added. We added a house extension to increase the amount of space, as well as light, and the end result was quite satisfactory. We also conducted basement conversion that helped add even more room for the denizens. The final touch was a total refurbishment of the house, with walls being repainted and rooms redecorated. The clients were very happy with the result.

London SW11

The main goal behind the project was to make the house appear bigger and have more space that can be utilised in daily life. We transformed a small and cramped room into a more spacious area, and later proceeded to convert the basement and loft. We managed to create a lovely space within the client’s budget. The entire house was then renovated and refurbished in order to match the transformed rooms.

London N10, UK

This was a house that had great potential, but required a great amount of work. We took our time to accurately bring our client’s vision to life. In the end, we managed to implement everything the client wanted several days ahead of the deadline.
