G+1 House Submission Drawing Set: Complete Guide for Building Plan Approval in India

Planning a new G+1 house is exciting, but before construction begins, one important step cannot be skipped—building plan approval. Every residential project requires a complete submission drawing set that is presented to the local municipal authority or development authority for approval. These drawings explain every important detail of the proposed building, including its location, dimensions, height, layout, and structural information.

Whether you are an architect, civil engineer, architecture student, or homeowner, understanding the complete G+1 submission drawing set helps you prepare accurate drawings and avoid approval delays.

This guide explains each drawing included in a G+1 house submission set, why it is required, what information it contains, common mistakes to avoid, and professional drafting tips for AutoCAD users.

When preparing a G+1 house plan, it is important to consider applicable building regulations and safety requirements. The National Building Code of India 2016 provides a broad framework covering building requirements, fire safety, structural design, construction practices, and building services.

What is a G+1 House Submission Drawing Set?

A G+1 House Submission Drawing Set is a collection of technical architectural drawings prepared for obtaining permission to construct a Ground Floor plus First Floor residential building. Instead of submitting a single floor plan, authorities require multiple drawings that together describe the complete building proposal.

The drawing set demonstrates that the building follows local building bye-laws, zoning regulations, setback rules, height limits, parking requirements, and safety standards. Once approved, these drawings become the official reference during construction.

In simple words, submission drawings create a bridge between the building design and legal construction approval.

Why Submission Drawings Are Important Before Construction

Many homeowners think construction can begin immediately after preparing a house plan. In reality, construction without approved drawings may lead to penalties, notices, or demolition in some jurisdictions.

A professionally prepared submission drawing set helps:

Obtain building permission from municipal authorities.
Verify compliance with local building bye-laws.
Show proper setbacks and open spaces.
Calculate built-up area, plot coverage, and FAR/FSI.
Ensure proper drainage, ventilation, and structural planning.
Reduce construction errors during execution.

Approved drawings also become useful during utility connections, property documentation, and future renovations.

What Is Included in a Complete G+1 Submission Drawing Set?

A standard residential submission drawing set generally includes:

Site Plan
Ground Floor Plan
First Floor Plan
Terrace or Roof Plan
Front Elevation
Side Elevation (where required)
Building Section
Foundation Plan
Structural Layout
Area Statement
Door and Window Schedule
Construction Notes
Title Block and Project Information

Each drawing serves a different purpose during the approval process.

Site Plan – The First Drawing in Every Submission Set

The site plan is one of the most important drawings because it shows how the proposed building sits within the plot boundaries.

It provides a top view of the entire property and nearby surroundings so authorities can verify whether the building respects required open spaces and access roads.

Information Included in a Site Plan

A professional site plan contains:

Plot dimensions.
Plot number.
North direction.
Road width and road location.
Entry gate.
Building footprint.
Front, rear, and side setbacks.
Compound wall.
Parking location.
Septic tank or sewer connection.
Rainwater harvesting location (if applicable).
Water tank location.
Existing structures (if any).

The site plan is usually prepared at a smaller scale because it covers the complete plot along with nearby roads and neighboring properties.

A complete G+1 project may require a site plan, floor plans, elevation, section and other technical drawings. For a detailed explanation, see our G+1 House Submission Drawing guide.

Why the Site Plan Is Important

The site plan helps authorities verify:
- Building position within the plot.
- Required setbacks.
- Road alignment.
- Accessibility.
- Ground coverage percentage.
- Plot utilization.
Without a clear site plan, building approval is usually incomplete.

Ground Floor Plan – Functional Layout of the Ground Level

The ground floor plan explains the arrangement of all rooms located on the ground floor.

It is one of the most detailed drawings because it includes dimensions, wall thickness, openings, staircase position, furniture layout, and circulation space.

For a preliminary understanding of construction costs, readers can also refer to the latest CPWD Plinth Area Rates, while keeping in mind that actual construction costs vary by location, specifications, materials, labour and design.
