CODE: N01 · ARCHITECTURAL & ENGINEERING FEES

Architecture, Engineering & Project Design Fees

Fees depend on housing typologies, building scope, deliverables and local coordination requirements as well as gross floor area. We never apply a single generic house rate multiplied by the number of flats; our proposals are built on transparent work packages and verified engineering hours.

Budget Demarcation & Clarity

Three Distinct Project Budgets

Professional modular development requires financial clarity. Design services, offsite factory manufacturing, and site logistics/assembly are managed as three separate contracts.

01 Dedicated Contract

Design & Engineering Services

Feasibility, plot layout, bespoke housing typologies, Eurocode structural analysis, shared building MEP, manufacturing BIM models, and local permit coordination.

Quoted transparently by defined work packages and verified engineering hours.
02 Dedicated Contract

Factory Offsite Manufacturing

EN 1090-2 certified structural steel modules, high-performance exterior wall envelopes, certified fire/acoustic linings, complete MEP pre-installation, and turnkey bathrooms/finishes.

Fixed industrial production contract in Türkiye, based on locked engineering files.
03 Dedicated Contract

Logistics, Foundation & Site Assembly

Multimodal international shipping (road/sea), local reinforced concrete foundation interface, mobile crane erection sequence, and SERMODULA expert installation supervision.

Budgeted based on project destination, site accessibility, crane radius and local partner agreements.
Calculation Methodology & Standards

Pricing Formula & Work Packages Matrix

Total Design Fee = Pre-Development + Masterplan + Bespoke Dwelling Types + Building Architecture + Global Statics + Building MEP + CAM Files + Repeat Adaptations + Site Infrastructure + Specialist Audits + BIM/Logistics.

NO DOUBLE CHARGING RULE

100 apartments are never multiplied as 100 individual house projects; nor does a single house design cover the global engineering of a whole building. Approved typologies are never redrawn from scratch. Repeat blocks are charged at 20-40% for interface adaptation. Floor area rate is solely a control metric; proposals are constructed from defined work packages.

WP01 Reviewing existing verified documents costs less; every new plot or country requires fresh assessment.

Pre-Development & Feasibility

Pricing Input & Scope

Zoning constraints, local plan rules, boundary surveys, program briefing, workshop hours.

WP02 Even if modular building types are identical, every plot layout and slope demands unique engineering.

Site Masterplanning

Pricing Input & Scope

Land area, topography, sunlight/wind orientation, circulation, parking, and phasing.

WP03 Once a typology is approved, it is never redrawn; only varying modifications are charged.

Unique Dwelling & Apartment Typologies

Pricing Input & Scope

Number of distinct spatial layouts, core bathrooms, kitchen wet pods, and room programs.

WP04 Substantial reuse across repeated blocks; orientation, thermal boundaries and ground floor entries verified.

Building Architecture & Common Spaces

Pricing Input & Scope

Number of storeys, core stairs/elevators, corridors, exterior facade system, and roof terrace.

WP05 Single module analysis cannot replace the 3D building global calculation; repeated identical blocks enjoy 60-80% fee reduction.

Global Structural Engineering (Eurocodes)

Pricing Input & Scope

Total height, wind/snow loads, seismic zones, module stack load paths, and foundation node reactions.

WP06 In-dwelling module MEP is standardized once; central building risers and main switchgear are verified per building.

Building MEP & Central Infrastructure

Pricing Input & Scope

Central capacity, service shafts, energy metering, fire suppression, ventilation, and rooftop heat pumps.

WP07 High initial engineering workload; zero reproduction cost for duplicate modules rolling off the line.

Production CAM & Shop Drawing Package

Pricing Input & Scope

Unique steel frame variants, lifting lug engineering, assembly jigs, CNC cutting files, and connection hardware.

WP08 Drastically cheaper than first type development (from 600 EUR/plot or 20-40% of block package).

Plot / Block Interface Adaptations

Pricing Input & Scope

Positioning, ground level coordination, specific point loads, orientation, foundation interface documents.

WP09 Cannot be calculated simply by building floor area; tied to land scale and municipal connection demands.

Site Infrastructure & Landscape Coordination

Pricing Input & Scope

Internal roads, fire truck turnarounds, transformer station, drainage, shared paths, and landscape boundaries.

WP10 SERMODULA provides the modular technical baseline; local official signing duties remain within local architect scope.

Specialist Compliance & Local Permitting Support

Pricing Input & Scope

Acoustic testing reports, fire safety strategies, energy performance certificates, and local architect collaboration.

WP11 Separate management layer for multi-building complexes; protects the developer from site delays and costly crane idle time.

BIM Coordination & Logistics Staging Management

Pricing Input & Scope

Clash detection matrices, 4D erection sequence, truck arrival slots, crane footprint, and just-in-time assembly schedules.

Realistic Project Case Studies

Three Realistic Project Budget Scenarios

Examine how modular typologies, repetition efficiencies and multi-disciplinary engineering form transparent project budgets across three distinct typologies.

Case A
EUR · Excl. VAT

Case A: 20-Home Community (2 Types)

20 detached/terraced homes × 100 m² = 2,000 m² total floor area; 2 distinct 100 m² typologies; ~10,000 m² plot.

Development feasibility

Two bespoke home types

2 × €18,000 (CAM files included)

36.000 €

Plot interface adaptations

20 × €600 (levels & connections)

12.000 €

Infrastructure coordination

Excludes civil execution

8.000 €

BIM information management

Multi-plot revision control

6.000 €

Transport & crane plan

Excludes freight and crane hire

4.000 €

Specialist compliance coordination

Defined review; tests separate

6.000 €
Service Subtotal 88.000 €
Client Planning Contingency (10%) 8.800 €
Total Planning Framework + Contingency 96.800 €
Subtotal per Unit 4.400 € per dwelling
Subtotal per m² 44,00 € per gross m²
Total + Buffer per Unit 4.840 € per dwelling
