CSA Architects is an architecture practice based in Mossel Bay, Western Cape, specialising in residential projects, ranging from new builds to additions and alterations. We place emphasis on building a relationship of trust with our clients and manage their building projects with the utmost regard for their budget, brief, and programme.

From our practice in Mossel Bay, we are able to provide services throughout the Western Cape. Although residential architecture is our focus, our diverse portfolio also includes private hospitals, schools, offices, hotels and other commercial buildings.

Our Services

New Residential

The Garden Route has always been a very popular choice for property investment. We offer assistance in the selection of your stand/plot and can guide you through the complicated process of bringing your dream home to life.

After local authority approval, we can further assist to develop detailed drawings for construction purposes and negotiate tenders on your behalf. When providing a full service we are involved with the project during construction and ensure that the drawings and specifications are followed until final completion of the building contract.

Additions & Alterations

All new additions need to comply with energy efficiency legislation which can be complex. We assist with a design that suits your needs and obtain the necessary approval from the local authority.

Should you choose, a full service (after local authority approval) can be offered. Cornerstone is then involved with the project during construction and we ensure that the drawings and specifications are followed until final completion.

Building Inspections & Maintenance Reports

It’s an effort to maintain your holiday home from a distance. We can arrange an inspection of your home and provide a full report of the needed maintenance work.

Based on the report, we prepare specifications, obtain quotations from reliable contractors and inspect the work on a weekly basis (or more regularly for shorter projects). Progress is monitored and payment valuations are issued to you ensuring complete peace of mind.

Sectional Title Maintenance Plans

We assist sectional title body corporates/managing agents with compiling a maintenance plan as required by the STSM legislation. We also offer weekly inspections of routine maintenance work at housing developments.

Estate Agent as-built Drawings

When selling your home, the existing drawings are not always up to date. We can assist with a survey of your home and provide as-built drawings which are submitted at the local authority for approval.
