Frequently Asked Questions
We combine rigorous architectural discipline with super-prime luxury sourcing: bespoke Italian stone, handcrafted joinery, museum-grade art illumination, and discreet smart-home technology tailored to global lifestyles.
We offer One Design (£600 per room/zone), Unlimited Design (£900 per room/zone), and Design & Technical (£1,500 per room/zone). Whole-home architectural renovations receive bespoke turnkey proposals.
Yes. We prepare the complete technical drawing package, acoustic insulation certificates, and contractor documentation needed to obtain landlord and estate consent from the Grosvenor Estate and private managing agents.
Yes. Whether your project involves a ground-floor kitchen extension, commercial shopfront alteration, or internal structural modifications, our architectural team prepares all necessary technical drawings and submits applications directly to the local planning authority across City of Westminster. We coordinate structural engineering calculations, Building Control inspections, Party Wall surveyor agreements, and Thames Water build-over notices to ensure total regulatory compliance.
Absolutely. We maintain exclusive trade relationships with premier British fabric houses, bespoke joiners, artisan stonemasons, and European lighting manufacturers. From custom wool and linen upholstery to hand-finished brass hardware and bespoke fitted cabinetry, we handle the complete procurement, trade-discount negotiation, quality control, and on-site white-glove installation.
A single-room or concept design phase typically takes 2 to 4 weeks depending on revisions. Full technical packages and planning approvals usually require 6 to 10 weeks. For complete turnkey Design & Build renovations, including structural alterations, bespoke joinery, MEP first-fix, and final dressing, timelines generally range from 3 to 6 months, all managed under a transparent programme of works.
For single-room projects or phased refurbishments, clients can often remain in residence while work is zoned off cleanly. However, for whole-property structural renovations involving wall removals, full re-wiring, re-plumbing, and commercial fit-outs, we generally advise vacating for key messy phases to ensure safety, minimize disruption, and accelerate contractor efficiency on site.
