About RELM Interiors
One team that designs and builds.
RELM Interiors is a design and build company based in Wimbledon. For more than fifteen years we have renovated, extended and finished homes across South West and Central London, taking each one from the first drawing to the final coat.

For more than fifteen years we have delivered substantial residential renovations across South West and Central London, with more than 100 projects completed.
We manage every stage under one roof: initial drawings and planning, structural work, construction, finishes and handover. You have one point of contact and one accountable team, from the first conversation to the day we hand your home back.
Because design, building, finishing and joinery sit with the same company, decisions are made quickly and nothing is lost between trades. The result is a home that is planned carefully, built properly and finished to a standard that shows in every detail.

One team, start to finish
For homeowners
One point of contact and one accountable team. We plan the work, manage the approvals, build it and finish it, so you are never left coordinating separate trades.
For architects and designers
A reliable construction partner who respects the design intent. We are happy to build to your drawings and specifications and to keep you informed on site.
Made to measure
Wardrobes, cabinetry, storage and furniture are designed and made by RELM Bespoke, part of the RELM group, so the joinery is drawn for each room and finished to match the rest of the house.
Considerate on site
Tidy, careful working and regular updates on progress. We are members of the Federation of Master Builders and the Considerate Constructors Scheme, and a FENSA registered company.
