"Your home is where memories are made and visions become reality. We take that seriously."
Fellner Construction has spent more than 25 years in private residential construction, delivering extensions, bathrooms and full refurbishments across South London. Bathrooms were always part of that work — and over the years they became the part we are most passionate about, where precision, planning and finish matter most.
That is where the company now focuses its energy. We take on a select number of bathrooms each year — a deliberate choice, not a constraint — so every project receives our complete and undivided attention, from first conversation to final handover.
A bathroom is the most demanding room in a home to get right. Water finds every weakness, and every tile, fixture and fitting is judged up close, every single day. That is why we plan each project in detail before work begins — layout, waterproofing, services, materials and finishes — so that nothing is left to chance on site.
Every bathroom is priced in writing before work starts, with one point of contact from your first conversation to the final handover. When we finish, the room should look right on day one — and still look right years later.
From concept to completion, every bathroom project is delivered with the same commitment to precision and care — from the initial strip-out to the final seal.
A complete strip-out and refit — all plumbing, tiling, fixtures, and finishing. From bare walls to a beautifully completed space.
