From idea and design to a finished property in Koh Samui
We deliver full-cycle residential and commercial projects — from concept and design to construction, fit-out and final handover.
Что мы делаем.

Architecture, design, construction, renovation and technical supervision — five competencies brought together in one delivery system.
Villa design & construction
We create private villas and villa developments — from site analysis and architectural concept to construction and complete fit-out.
Renovation & commercial projects
Turnkey renovation of villas, restaurants, cafés, shops and other commercial spaces.
Представительство заказчика
и технический надзор
We represent the owner on site and control contractor performance.
You retain control over construction even when you cannot be on site every day.
An independent owner-side presence on site: we check what is actually happening and bring important decisions into a clear, manageable format.
What is actually on site
We compare completed work with the agreed design decisions and the current stage of construction.
Contractor coordination
We connect the participants and record the questions that require a decision from the owner.
Deviations and risks
We flag disputed details and deviations before they move into the next stages and become more expensive to correct.
Clear reporting
We give the owner a clear view of progress and the decisions that may affect budget and schedule.
How we work
From the first discussion to handover, the project follows a clear sequence of decisions and responsibilities.
Discuss the brief
The project, plot or existing property.
Review the inputs
We meet, visit the site and analyse the documentation.
Shape the solution

OG Lab
Realization of a complex of villas. The project combined engineering solutions and the organization of space for real business processes.

OG Lab
Complete delivery of a two-storey commercial space: a retail area on the ground floor and a production facility above. The project combined construction, engineering and spatial planning around the client's actual business processes.

Library Samui
The premises underwent a complete renovation: all engineering systems, glazing, finishes and interiors were fully replaced. As a result, an ordinary space was transformed into a modern commercial property.

Gudimov Residential Complex
Business-class construction with three residential buildings and two-level underground parking. Alexander participated as Site Manager, from site preparation and excavation through completion of the complex.

Based in Koh Samui
We are based directly in Koh Samui and work with local contractors, specialists and suppliers.
Alexander Arzhanov
Я вырос в семье строителя и работаю в строительной сфере с детства. Прошёл путь от работы непосредственно на стройке до прораба и начальника участка.
У меня два высших образования: экономика в строительстве и промышленное и гражданское строительство.
В России я много лет занимался строительством многоэтажных жилых комплексов с подземными парковками — от начала работ на площадке до полной готовности объекта и передачи ключей.
Позже развивал собственную строительную компанию по малоэтажному строительству, а затем собственный проект в сфере общественного питания и retail.
Сегодня в ARJAN DEVELOPMENT я объединяю проектирование, архитектуру, дизайн, строительство, реновацию и технический контроль.
