Design Eleven is run by a qualified quantity surveyor. The estimate you sign is itemised line by line — so you can see what every rupee buys before anyone breaks ground.

From design and costing through to construction, steel fabrication and plumbing — every service is owner-led from first visit to handover.
New builds, extensions, and structural repairs — residential and commercial.

Custom steelwork — gates, grilles, staircases, structural elements, balustrades.

Full plumbing services — installation, renewal, and maintenance for homes and commercial spaces.

Titanium floor finishes — a smooth, high-strength, seamless surface for modern interiors.

Architectural and interior design — from concept drawings to construction-ready documentation.


Most of what goes wrong on a build goes wrong because nobody agreed what was included. This is how we avoid that.
We come to the property, listen to what you want, and look at what the site will actually allow. Access, ground conditions, services, boundaries.
A written quote broken down line by line — materials, labour, timeline, payment milestones. Priced by a quantity surveyor, not guessed at.
We start on the agreed date. Weekly photos and a written update, one point of contact, and any variation priced in writing before it happens.
Walk-through, defect list, and every document handed over — approvals, warranties, as-built notes. We come back to close out defects.
The team ran the build themselves. Every site visit, every decision, every problem — they were there. We always knew where the project stood. That alone made the experience worth it.
A site visit and an estimate cost nothing. Tell us what you’re thinking — we’ll give you a straight answer and an honest number.
