What Maris Interiors LLP does

Maris Interiors LLP is a UK-based, privately held Limited Liability Partnership founded in 1977 and headquartered at The Harlequin Building, 65 Southwark Street, London. The firm operates an integrated Design & Build delivery model for commercial workplace and higher-education interior projects, serving enterprise clients across financial services, technology, insurance, gaming, fashion, professional services, and university sectors. Its nine service lines span Workplace Consultancy, Space Planning & Design, Project Management, Cat A Works, Construction, Office Fit-Out, Refurbishment, Post-Construction, and Furniture Solutions, all delivered under single-point accountability contracts.

The firm's core technology is its integrated delivery architecture rather than a software platform. A 200-strong in-house team consolidates architecture, quantity surveying, project management, mechanical engineering and construction capability under one roof, eliminating the typical adversarial split between designers and builders. Its proprietary Total Project Costing (TPC) methodology breaks capital expenditure into three ring-fenced budget buckets — The Hard Build (Construction Pot), The Agile Assets (FF&E and Tech), and The Soft Costs (Professional Fees) — to lock budget before breaking ground and provide cost certainty against inflation. The firm claims 30-40% faster delivery than traditional procurement routes and a 93% repeat business rate, with 2,000+ projects and 36 million+ sq ft delivered across 49 years.

Maris generates revenue through project-based, lump-sum fixed-price contracts for complete workspace transformations. Pricing is quote-driven and benchmarked against UK fit-out cost guides, with Cat B fit-outs in Central London ranging £120-£180 per sq ft for the construction element alone. Go-to-market is direct enterprise field sales, supported by an extensive content-marketing engine (sector guides, newsletters, case studies) and a substantial portfolio of pre-qualifications (Constructionline Platinum, ISO 9001/14001/27001/45001/37001, Achilles UVDB, FSQS, Pagabo, Constellia, SafeContractor, RoSPA Gold) that enable access to both enterprise and public-sector tenders. The firm is debt-free, with no external capital, partnerships, or M&A activity disclosed.
