Your Trusted A&A Contractor for Landed Houses
Alexis Design and Build provides professional Addition & Alteration (A&A) services in Singapore, specialising in landed houses such as terrace houses, semi-detached houses and bungalows.
A&A works allow homeowners to extend, reconfigure or upgrade their existing home without fully rebuilding it. This may include adding rooms, extending the house, changing layouts, adding new floors, or making major structural modifications.
Because A&A involves structural changes and authority approvals, it requires proper planning, technical knowledge and responsible execution. This is where Alexis Design and Build makes a real difference.
