Renovating in Erenköy: Flats and Houses in a District of Garden Mansions (2026)
A little inland from the coast, Erenköy is one of Kadıköy's established neighbourhoods, known for its garden-mansion past and quiet streets. Renovation here takes its shape from very different building types — from garden-level flats to older detached houses.

Once known for its garden mansions, Erenköy is a Kadıköy neighbourhood that still keeps its tree-lined, quiet streets. Over time, apartment buildings have replaced some of the old mansions, while other older buildings have survived. So renovation in Erenköy doesn't fit a single template: a garden-level flat, a newer apartment and an older detached house each call for a very different approach.
Damp and drainage in garden-level flats
In the ground and garden levels of apartment buildings with gardens, the most common problem is damp coming up from the ground and in from the garden side. Blistering paint and mould at the base of walls can't be solved from the inside surface alone; garden drainage, waterproofing around the foundations and indoor ventilation need tackling together. Interior renewal done after that groundwork holds up.
Renewing older detached houses as a whole
In the older detached houses that survive in Erenköy, the roof, facade, services and structure need assessing together. Some may carry heritage status, in which case work affecting the exterior can require conservation-board approval. Establishing the building's condition and status first makes the right order of work — and a realistic timeline — possible.
A tidy worksite on a tree-lined street
Erenköy's quiet, tree-lined streets shape the logistics too: parking is limited, large vehicles can't easily reach every street, and garden trees need protecting. Deliveries and debris removal happen at planned times in small loads, and in buildings with gardens the work area is fenced off so tree roots and planting aren't damaged.
Frequently Asked Questions
- Can the damp in my garden-level flat be fixed for good?
- Yes, if the source is correctly identified. Depending on the cause, drainage, waterproofing and ventilation fixes go in before the interior work.
- Where do I start with renewing an old mansion-style house?
- With a site visit and assessment that establishes the building's condition and heritage status. That step shows what can go ahead right away and what has to wait for approval.
- What drives renovation cost in Erenköy?
- The building type and age, and how far any damp or infrastructure problems go, set the cost; the real figure comes after a free site visit — we don't quote one here.
