Dear Members,

We believe that compiling the frequently asked questions and answers addressed to the KTMMOB – Chamber of Architects Permit Office will save time both for our members and for the permit office staff. We aim to periodically update these frequently asked questions and share them with you through our Chamber’s website. The frequently asked questions and answers can be found under two main sections: “Legislation – Drawing Techniques” and “Project Submission – File Preparation.”

In order to make the answers more understandable, the study also includes the necessary figures, drawings, and tables. For more comprehensive explanations of certain questions, references have been made to the “Architect’s Handbook,” the “Chapter 96 Law,” and the “Chapter 96: Roads and Buildings Regulation Law Summary Guide.” Therefore, it may be necessary to access the digital versions of these reference sources together with the written answers. These references are also available on our Chamber’s website.

We would like to thank everyone who contributed to the realization of this study, especially our technical permit office staff, and we wish you success in your professional work.

KTMMOB Chamber of Architects
53rd Term Board of Directors

QUESTIONS AND ANSWERS RELATED TO LEGISLATION – DRAWING TECHNIQUES

What should be the drawing technique for renovation and alteration projects?

Existing elements, demolished parts, and additions should be expressed using three different techniques. Project hatchings should be minimized and arranged legibly with a 0.2 pen thickness. See Figure 1: Example Renovation Legend.

How should title deed site plans be prepared in subdivision projects?

New road alignments and new parcel boundaries should be indicated with continuous uninterrupted lines using 0.2 red rapidograph pen. Dimensions should be written numerically directly on parcel boundaries without using dimension lines.

New parcel numbers / green areas and similar newly created areas should be numbered within circles using 0.2 red rapidograph pen.

How should projects that do not fit within the horizontal A0 (84.1 × 118.9 cm) sheet size stipulated in our legislation be submitted?

For projects that cannot be presented at 1/50 scale due to project size, an application must be submitted to the Board of Directors together with a key floor plan and petition. Such projects should be presented at 1/100 scale using 1/50 drawing techniques.

What should the scales of site plans be?

Depending on the site size, site plans may be submitted at 1/100, 1/200, or 1/500 scale, provided that they fit within a horizontal A0 (84.1 × 118.9 cm) sheet size.

In which building types is a landing required after 14 risers?

A landing is not mandatory after 14 risers in buildings other than public and shared-use buildings.

What should be the minimum width of a staircase leading to an upper floor?

In accordance with human ergonomics, the staircase width must be at least 80 cm.

What is the maximum slope permitted for basement parking ramps in detached houses and public buildings?

In detached housing projects, the maximum ramp slope may be up to 18%, while in public and shared-use buildings it may be up to 15%.

If more than one identical building type is constructed on the same plot, how is the architect’s fee calculated?

The first building type is calculated at 100%, the second at 50%, the third at 25%, and the fourth and subsequent ones at 15%.

If identical building types are submitted on different parcels and in separate files, can they still be considered repetitive projects?

No.

If planning approval is granted for multiple buildings within the same file, can these buildings be submitted separately for permit approval at different times?

Yes.

If an elevator addition extends beyond the building envelope, is the cost reflected as an area increase or as an estimated construction cost?

It is reflected as a construction estimate cost.

In subdivision projects where road setbacks are made both from the road side and through roads dividing the land, what area is reflected in the costs?

Newly opened road areas resulting from the setbacks are reflected in the costs according to the subdivision unit cost.

What should be the minimum architectural fee for subdivision projects?

Half of the percentage corresponding to the first-class building coefficient calculated over the newly opened road cost should be taken (1.2% × 0.5 = 0.6%).

What should be written in the costs when land subdivision is carried out together with buildings?

The existing road area is divided by two and multiplied by the subdivision unit cost to determine the subdivision approximate construction cost, while the current unit costs of the buildings are used for the building subdivision.

How should subdivision projects be submitted according to the Condominium Ownership Law?

They must be submitted together with a copy of the construction permit and the table prepared according to the Condominium Ownership Law. See Figure 2.

What are the architect’s fees for subdivision and survey projects?

The architect’s fee is calculated as if it were a new building using current unit costs. For subdivision projects, 10% of this fee is charged, while for survey projects 30% is charged.

Can mechanical ventilation for a WC on a single floor discharge directly through an external wall without a shaft?

Yes, in single detached independent units it may discharge directly through an external wall.

If a high-voltage power line passes through land within Chapter 96 zones, how far should the building be located from these lines?

If there is a high-voltage line, approval should be obtained from the Electricity Authority and the necessary setback distance should be applied.

In site-type and apartment subdivision projects, can open parking areas and ground-floor land areas be common-use spaces with allocated usage rights?

If sufficient parking spaces are provided according to the number of independent units as required by legislation, they may remain common-use spaces with allocated usage rights. Exclusive ownership rights cannot be assigned to land areas; they must be indicated as common-use areas.

SECTION

PROJECT SUBMISSION – FILE PREPARATION

In what situations should a pre-license amendment project be submitted? How should it be submitted?

Any modification made to a project before obtaining a construction permit must be submitted as a completely new project.

In what situations is a survey project required? How should it be submitted? What should the costs be?

If structures built before 1981 are not registered on the title deed but are documented by the village headman (mukhtar), they should be drawn within the scope of a survey project.

The registered portions should be drawn using existing building techniques, while the unregistered portions subject to survey should be drawn using new project techniques.

The surveyed sections should be calculated based on current unit costs.

How should road longitudinal sections and table presentations be prepared in subdivision projects?

See Figure 3 – Road longitudinal sections and table presentation in subdivision projects.

How should files prepared for tendering be organized?

See the Architect’s Handbook, page 25, article 2.2.10.

How is Tangent 55 calculated?

See Chapter 96, Part VI concerning height and area, clauses (c) and (d).

How should levels be arranged on sloped land according to ±0.00 (spot elevation level)?

Please consult the Department of Town Planning in your region.

What is meant by zoning area and construction area?

Construction area refers to all covered areas excluding voids within floor slabs. Zoning area refers to the areas defined under Chapter 96 or the legislation applicable in your region.

What should be the maximum height of a service floor?

The finished service floor height (interior ceiling height measured from finished floor level) must not exceed 180 cm.

What should be the minimum width of fire escape doors in public buildings?

They must be at least 120 cm wide.

How should level references be given for different buildings and terrain on sloped land?

Each building’s ground floor level should be referenced according to ±0.00, while terrain levels should be written in parentheses next to the entrance levels.

How should row houses be typified? How should they be reflected in costs? What should the building classification be?

In row housing, blocks are considered as a whole, and the total block area is reflected in the costs. The building classification of the standard house type is used.

What should be written in the costs of renovation projects? How is the architect’s fee calculated?

Twice the renovation estimate and quantity survey value should be written in the contracts, and the architect’s fee is calculated based on this amount. In the M01 legend, the renovation cost should be stated.

Is authorship certification required in building subdivision projects?

Yes.

How should the 30-meter staircase distance rule be calculated?

The travel distance from the door of the furthest space in the project to the first stair step must not exceed 30 meters.

In public and shared-use buildings, should staircases provide access to the roof?

Yes. Roof access must be provided from the common circulation area.
