Grand Staircase Villa: a Surat home built around its staircase
A villa in Surat — a red-carpeted floating staircase, a mezzanine lounge, gold-veined marble walls and a formal dining room. The design story, the material logic, what a villa like this costs — and the six 3D renders the family approved before execution began.
The brief
A villa gives you what an apartment never can — volume. The design spends that volume in four moves, each one visible in the renders below:
- The staircase is the architecture. A floating staircase — treads that read as if they hover — dressed with a red carpet runner. It is the first thing guests see and the thread that ties both levels together.
- A mezzanine, not just a landing. A lounge sits on the half-level overlooking the double-height volume — family space with sightlines down to the staircase and the entrance below.
- One luxury surface, everywhere it counts. Gold-veined marble walls carry the premium feeling; the rest of the palette stays quiet so the stone does the talking.
- Dining gets its own room. A formal dining room — not a corner of the living area — detailed for hosting, with the lighting and wall treatment a special-occasion room needs.
Material logic
The spec sheet behind the look
We don’t publish any client’s actual BOQ — but if you asked us to build this look today, this is the specification it would start from. Ranges are Surat-market 2026, taken from our pricing hub.
| Feature | What you see in the renders | The spec it implies (typical, Surat 2026) |
|---|---|---|
| Floating staircase | Treads cantilevered off a concealed steel/MS spine; stone or solid-wood treads, red carpet runner | Priced per flight on the BOQ — structure + treads + railing. This is the home’s single biggest bespoke line item. |
| Red carpet runner | Bound stair-runner carpet laid over the treads — the colour moment of the house, and grip underfoot | Quoted per flight on the BOQ — pile, density and binding decide the band. |
| Gold-veined marble walls | Book-matched slabs so the veining flows across panels instead of stopping at each joint | Italian marble supply runs ₹250–600+ per sq ft in Surat in 2026; book-matching is a laying decision, not extra stone. |
| Mezzanine lounge | Half-level lounge overlooking the double-height volume, with lounge joinery and railing | Priced as structure + joinery — quoted per design on the BOQ. |
| Formal dining room | Wall paneling, layered lighting over the table, furniture scaled for hosting | Laminate-finished paneling ₹350–650 per sq ft; veneer ₹800–1,500 — typical Surat 2026. |
The luxury here is concentrated, not spread: one stone, one colour moment (the red runner), one structural gesture (the floating stair). Concentrating the budget is what makes a villa feel expensive without being expensive everywhere.
Budget, honestly
What does a villa like this cost in Surat?
The bill for this exact home is private. What we can show you is the maths any villa of this scale follows in Surat in 2026:
- Design fee: ₹250 per sq ft of carpet area. For illustration, a villa plan of about 3,000 sq ft carries a design fee of roughly ₹7.5 lakh — concept, 3D views, working drawings, itemised BOQ and site supervision included. Illustration, not this home’s bill.
- Execution, mid-range: ₹1,200–2,000 per sq ft — villa interiors in Surat land at ₹20 lakh and above all-in — branded plywood, soft-close hardware, stone accents, layered lighting.
- Execution, premium: ₹2,000–3,500+ per sq ft — book-matched marble, bespoke joinery, imported hardware; the floating staircase alone is a significant bespoke line item.
Bands, not quotes: every villa is quoted item-by-item after a site visit. Read the full pricing hub or the per-sq-ft cost breakdown before you compare any two quotes.
Process
How this villa was designed
- 3D first: every space was finalised as a 3D render — the six views below are that exact stage — and approved by the family before execution began.
- Drawings, then site: working drawings for civil, electrical, staircase structure and furniture details were issued from the approved renders, so the site team built from drawings, not discussions.
- Supervised execution: site supervision visits ran through the build, the same way every Aaditya Interior project is run from our Katargam studio.

How much does a villa interior cost in Surat in 2026?
Villa interiors in Surat in 2026 land at ₹20 lakh and above all-in at mid-range (₹1,200–2,000 per sq ft), and ₹2,000–3,500+ per sq ft at premium level — where stone, bespoke joinery and imported hardware decide the band. These are market bands for a villa of this scale — the actual bill for the Grand Staircase Villa is private, and every project is quoted item-by-item after a site visit.
What is Aaditya Interior’s design fee for a villa?
Our design fee is ₹250 per sq ft of carpet area — for illustration, a villa plan of about 3,000 sq ft carries a design fee of roughly ₹7.5 lakh. That covers concept, space planning, detailed 3D views of every room, working drawings, an itemised material BOQ and site supervision while the design is executed. Execution is billed separately on the approved BOQ.
Is a floating staircase safe in an Indian family home?
A properly built one is. The treads you see in these renders cantilever off a concealed steel spine fixed into the wall or a central stringer — every tread is engineered to carry its load, and the red carpet runner adds grip underfoot. What looks like a trick of the render is actually one of the oldest structural ideas in stair design, detailed honestly.
Can I get the gold-veined marble look without the Italian-marble bill?
Yes — the trick is vein continuity, which is a design decision more than a material price. Use book-matched slabs on the one or two walls that carry the room, and a large-format marble-look tile or a quieter natural stone elsewhere. In Surat in 2026, Italian marble supply runs ₹250–600+ per sq ft — so where you place it matters more than how much you buy.
