Before design: survey and soil test
A plot survey checks that the plot on the ground matches the papers. It records boundaries, road and neighbouring levels, and any surprises such as a pole, tree or drain. In societies, demarcation is often done by the society office. The architect needs these measurements before drawing anything.
A soil test tells the engineer how much load the ground can carry and whether the water table is high. It is especially advisable for basements, larger houses or plots near low-lying land. Skipping it means the foundation is designed on assumptions.
Design and approval: naqsha, structure and submission
The architect develops the naqsha in stages: concept layouts, refined floor plans and 3D views, then final working drawings. Sign off each stage before moving on. Alongside, the structural engineer designs the frame and foundations, and services layouts for water, drainage and electrics are prepared.
The approval file usually includes the architectural and structural drawings plus ownership documents and forms set by the authority. Requirements on covered area, height and setbacks vary, so confirm the current rules with your authority. Do not start construction until approval is received.
- Check the final naqsha against your brief before submission
- Make sure architectural and structural drawings agree with each other
- Keep stamped approved drawings safe and a copy on site
Building and finishing: contractor, construction and completion
Give each contractor the same drawings and specification so quotes are comparable. A clear agreement covers scope, materials, stage payments, timeline and how changes are handled. Decide whether you want labour-only, grey structure or full construction.
During construction, key inspection points include excavation and foundation, steel placement before each slab is cast, brickwork, roof waterproofing, and services before plastering. Having the architect or engineer check these stages prevents hidden mistakes.
When the house is finished and built as approved, apply to your authority for a completion certificate. It is often needed for utility connections, sale and peace of mind, so plan for it from the start rather than treating it as an afterthought.
