What you can see from the front door

The view from the entry decides the whole privacy structure of a house. Five things that should never be in it.

Visitors see straight into your private rooms from the front door

You open the front door to collect a parcel, and the delivery courier looks past you directly into the master bedroom. A guest sits on the sofa in the living room and has a direct view into an open bathroom. These sight line failures happen when a floor plan treats doors as isolated openings rather than visual control points.

Correcting sight line errors after construction is difficult and expensive. Once reinforced concrete columns and brick walls are in place, shifting an opening means breaking masonry, cutting lintels, and patching floor tiles. Reworking a single doorway after plastering easily wastes thousands of rupees, and moving plumbing lines to shift a visible water closet costs far more. With construction costs running from ₹1,600 to ₹2,000 per sq ft for basic finish and ₹2,000 to ₹2,800 per sq ft for standard finish, structural modifications quickly consume your contingency budget.

Privacy in a home does not depend on keeping every interior door shut. Privacy is created by the geometry of your plan. Where walls overlap, how doors swing, and what sits at the end of each path of travel determine what people see.

The rules for sight lines and clearances

Visual privacy follows strict spatial relationships. In our professional practice rule base, we enforce definite rules for openings, sight lines, and circulation spaces.

• No bed may be visible from the house entry.
• No bed may be visible from a seated position in the living room.
• Circulation must never cross the front of a bed.
• A bathroom must never be the first thing seen from any room entry door.
• A corridor must not end on a blank wall; it must terminate on an intentional view or light source.
• No door leaf may swing into a corridor or lobby.
• Every door leaf must clear interior fixtures by at least 50 mm.
• A clear corridor width of at least 914 mm inside finished partition faces must be maintained, as specified by the National Building Code Part 3.

The table below outlines these rules alongside the clearances required to keep sight lines and movement functional:

How sight lines are applied across the floor plan

Arranging sight lines correctly begins at the site threshold. In traditional Tamil planning, houses follow a tested sequence: thinnai, then hall, then mutram, and finally private bedrooms and kitchen. The thinnai provides a covered outdoor threshold where shoes come off. Next comes the public hall, followed by an open central court, and finally the private family quarters. This sequence is an organizing system for privacy. A visitor standing at the front door grasps the layout of the house instantly while private sleeping quarters remain hidden around corners.

Applying this in a modern plan requires treating doors as the highest-leverage element in the house. A complete door review must examine hinge placement, swing direction, and visual angles across the whole floor plan at once.

When you enter a bedroom, the door leaf should open against a wall so that the open panel conceals the bed during the first part of the swing. The head of the bed must sit against a solid wall, never against a wall shared with a bathroom or a kitchen. Circulation inside the bedroom should move toward a dressing zone or an attached bath without ever crossing between the bed and the opposite wall.

Corridors require equal care. The National Building Code Part 3 requires corridors to maintain a clear internal width of 914 mm. That width must not be treated as a dark tunnel that dead-ends into a bare wall. Terminating a corridor view with an exterior window, a small courtyard, or an offset opening brings in natural light and gives the eye a destination. This creates visual depth without adding square footage to your build.

The mistakes this prevents on site

Ignoring sight lines and door swings during early planning creates expensive conflicts on site. When door leaves clash with fitted furniture or sanitaryware, the fittings must be trimmed down or removed entirely.

In our own drawing practice, our automated rule checks have caught serious layout defects that human reviewers missed:

• A bedroom door leaf was drawn striking a 600 mm deep wardrobe by 567 mm, preventing the bedroom door from opening past halfway.
• A bathroom door leaf struck a vanity counter by 290 mm, which would have forced the homeowner to cut down the vanity on site.
• A corridor was laid out at 804 mm clear width instead of the 914 mm required by the National Building Code Part 3, because a 110 mm internal partition was added without adjusting the framing boundary.
• Two 900 mm doors were positioned starting 60 mm inside a 914 mm corridor, resulting in door openings that did not sit inside real walls.

These errors create immediate losses during construction. Breaking a masonry partition to relocate a door frame or moving plumbing rough-ins for an exposed water closet costs between ₹15,000 and ₹40,000 in labour and ruined materials. Getting the geometry right before laying the first course of masonry prevents these losses.

What this means for your plan

Check your sketch to verify that no open door or seated living room position exposes a bed or a bathroom pan. Confirm that every corridor maintains at least 914 mm of clear space and terminates on natural light rather than a blank partition. The tool applies these sight line and clearance rules automatically when it generates your concept sketch. You can then hand a validated brief to your architect or structural engineer before structural drawings and site excavation begin.
