The Treehouse Interiors

What The Treehouse Interiors does

The Treehouse Interiors is a privately held, founder-led interior design studio established in 2000 by Stephen Hodgkinson and Philip Martinson and headquartered in Doddington, Lincolnshire, United Kingdom. The studio offers a full interior design consultancy covering concept development, moodboards, material samples, visualisations, supplier trips, detailed consultations, design-and-build, refurbishment, and full decoration services. Its core technology and capability stack is human design expertise and a curated supplier ecosystem rather than software; deliverables are bespoke interior schemes produced on a project basis for individual clients.

The company serves high-net-worth private residential clients across the UK, the Channel Islands, and Europe, with a documented portfolio spanning London (Kensington, West London, Albert Hall Mansions), Leeds, Nottinghamshire, Lincolnshire, and Spain (Casa V villa and gardens), including Grade I and Grade II listed period properties. It also serves boutique hospitality operators (The Castle Hotel in Lincoln's Cathedral Quarter) and residential property developers as secondary segments. Work is acquired through referrals, direct client enquiry via phone and email, and a website portfolio plus journal that functions as the primary marketing surface.

The revenue model is professional services on a project-based, quote-based pricing structure with no public rate card or standardised tiers. Engagement scope is high-value and typically encompasses whole-property refurbishments or design-and-build, with revenue concentrated in a small number of large engagements per year. There are no funding rounds, no external investors, and no disclosed revenue figures. The firm is a 1–10 person boutique operation and remains owner-operated by its two co-founders.
