From Sketch to Sanction: The Full Design Timeline Explained

Most homeowners who speak to architects in Mysuru ask the same first question: how long before construction can actually begin? The honest answer is that it depends less on how fast someone can draw and more on how cleanly each design stage hands over to the next. A plan that skips a step usually comes back to it later, and that is where the months disappear.

This article walks through the full design timeline in the order it really happens, from the first rough sketch to a sanctioned plan you can build from. For each stage you will see what gets produced, what decisions you need to make, and what tends to cause delays.

The durations mentioned are hedged typical ranges only. Your plot, your brief and the authority handling your file will decide the real numbers.

Stage 1: Brief, site visit and survey

Everything starts with two inputs: what you want and what the plot allows.

Your brief should cover the number of bedrooms, who lives in the house now and in ten years, parking needs, a home office or rental unit, vastu preferences if any, and a realistic budget. A budget stated early is not a limitation on the architect. It is the single most useful design input, because it decides the built-up area, the structural system and the finish level.

The site visit and survey record the plot’s actual dimensions, levels, road width, orientation, neighbouring structures, trees, drains and existing services. Plots in older Mysuru layouts often measure slightly differently from the sale deed, and it is far cheaper to find that out now than at the sanction counter.

Documents to gather at this stage:

• Sale deed and title documents
• Khata certificate and latest tax paid receipt
• Encumbrance certificate
• Approved layout plan, if the plot is part of a layout

Typically this stage takes one to two weeks, mostly driven by how quickly the documents come together.

Stage 2: Concept sketches and design-to-budget checks

With the survey in hand, the architect produces concept sketches: zoning of rooms, circulation, stair position, light and ventilation, and parking. This is the cheapest point in the whole project to change your mind, so use it.

Good concept work tests the design against the budget before anything is detailed. The simplest way to do that is to multiply the proposed built-up area by a package rate. At Uniq Builders, for example, the starting rates are ₹1,999 per sq ft for Premium, ₹2,499 per sq ft for Gold and ₹2,999 per sq ft for Platinum (terms and conditions apply, with the final figure confirmed after a free site visit). If the concept overshoots your budget, trim area or simplify the form now, not after the working drawings are done. You can compare what each level includes on the construction packages page.

Also remember that site conditions such as rock excavation, extra foundation depth or imported filling earth are quoted separately after the site visit, so leave room for them.

Stage 3: Soil test, structural design and 3D elevations

Once the layout is agreed, two tracks run side by side.

The soil test tells the structural engineer what kind of foundation the ground can support. Skipping it means guessing, and guessing on foundations is either wasteful or unsafe. The structural design, covering footings, columns, beams and slabs, is then built on real data.

The 3D elevations show how the house will look from the street. Ask for more than one option. In Uniq Builders’ architectural design service, clients choose from a set of 3D elevations and the one they pick is the one that gets built, so the front of the house is settled before drawings are finalised.

Decisions to lock in during this stage:

1. Elevation choice, including window sizes and balcony projections
2. Roof type and any future floor you want the structure to carry
3. Staircase and lift provision
4. Rough locations for water tank, sump, septic or sewer line and solar panels

This stage commonly takes three to six weeks, depending mainly on how quickly elevation choices are made.

Stage 4: Working drawings and revisions

Working drawings are what the site team actually builds from. A complete set usually includes floor plans for every level, sections, elevations, door and window schedules, electrical and plumbing layouts, and the structural drawings.

Revisions are normal, but they need a boundary. Uniq Builders’ design scope includes working drawings for all floors with up to three rounds of revisions, along with smart-home planning if you want it. Whatever firm you use, ask how many rounds are included, because open-ended revisions are one of the most common reasons design timelines drift.

Tips to keep revisions productive:

• Collect all family feedback into one marked-up set rather than sending comments in pieces
• Settle furniture layouts for the kitchen and bedrooms before electrical points are fixed
• Confirm plumbing positions before the structural drawings are frozen

Expect roughly three to six weeks here for a typical independent house, longer for commercial or mixed-use buildings.

Stage 5: Sanction and approvals

The sanction drawing is a version of your design prepared to the local authority’s format, showing setbacks, coverage, floor area and other planning parameters. The exact rules differ between the Mysuru city authority, development authorities and panchayat areas, and they are revised from time to time, so confirm current requirements with the authority or a qualified professional rather than relying on old figures.

What the approval stage generally involves:

• Preparing and submitting the sanction plan with ownership documents
• Responding to any queries or site inspection
• Paying statutory fees
• Following up on khata, power, water and sewage connections

Uniq Builders provides free assistance for government licensing work in every package, and handles plan sanction, khata and licences, and utility connections, while statutory fees are paid directly by the client. Processing times depend entirely on the authority and the completeness of your file, so treat any estimate as indicative.

Frequently asked questions

Can construction start before the plan is sanctioned?

It should not. Building without a sanctioned plan can lead to notices, penalties or difficulty getting utility connections and loans. Use the approval waiting period to finalise interiors, materials and the construction specification instead.

What slows the design timeline down the most?

Incomplete ownership documents and repeated late changes are the usual culprits. Changing the layout after structural drawings are done forces several drawings to be redone. Making firm decisions at the concept and elevation stages saves the most time.

Is the soil test really necessary for a small house?

Yes. Even a modest house carries significant load, and soil in the same neighbourhood can vary from plot to plot. The test lets the engineer design a foundation that is safe without being oversized.
