Overview
SilverDoor is a United Kingdom-based serviced-apartment agency headquartered in Chiswick, London. The company arranges furnished and serviced accommodation for corporate and private customers, working with a global network of apartment providers rather than operating primarily as a conventional hotel chain. Its services are used for employee relocation, staff-housing programmes, business travel, international assignments, project work, conferences, city breaks and other temporary-stay requirements. The company’s business model combines accommodation sourcing with account management and support for organisations that need to place travellers or relocating employees in suitable homes for periods ranging from short stays to longer assignments. This positions SilverDoor between a traditional travel-management company, a corporate-housing intermediary and a specialist accommodation marketplace. Its proposition is centred on breadth of supply, local market knowledge, service support and the ability to manage accommodation programmes across multiple countries. SilverDoor expanded its international presence through acquisitions and new offices. In May 2016 it acquired Citybase Apartments, broadening its serviced-apartment activities in the United Kingdom. Later that year it opened its first international office in Singapore. In 2017 it became part of Habicus Group alongside Citybase Apartments, Central London Apartments and Orbital Partnerships. The group structure brought several accommodation and partnership businesses together under a broader corporate-housing platform. The company opened an Americas headquarters in Denver in January 2019 and expanded its North American footprint through the acquisition of The Apartment Service in September 2021. In April 2022 it opened Iberia and Latin America headquarters in Madrid. Further international development followed with the opening of a Middle East headquarters in Dubai and the launch of a new global headquarters at Chiswick Park in 2024. SilverDoor has also maintained offices or operations in locations including San Francisco, Seattle, San Diego, Houston, New York, Dublin, Lancaster, Bangalore, Hyderabad, Singapore and Shanghai. SilverDoor has received repeated recognition from business-travel, corporate-housing, relocation and serviced-apartment organisations. Awards cited for the company include corporate-housing provider, apartment-agent, marketing, account-management, service-excellence and technology-innovation categories. Its more recent recognition has included work associated with a carbon calculator and other technology-led accommodation initiatives, reflecting the growing importance of sustainability measurement and digital tools in managed business travel. In 2025 the company marked 25 years in the industry. In August 2025 it announced a merger with Synergy Global Housing. The reference material states that the two businesses were scheduled to complete integration under the SilverDoor brand in April 2026, using an aligned technology ecosystem and unified team. Because that integration date is later than some historical reporting periods, the precise post-merger operating structure should be verified against current company information.
History
SilverDoor was established in the United Kingdom around 2000 and developed as a specialist agency for serviced apartments and corporate housing. Rather than being defined by a single hotel property or accommodation estate, its role has been to connect corporate and private customers with furnished apartments around the world and to support the associated booking and account-management process. Its early development focused on the needs of business travellers, relocating employees and organisations requiring temporary housing. These customers often need more space and domestic facilities than a hotel can provide, particularly for extended stays, family relocation, project assignments and repeat corporate programmes. SilverDoor’s agency model allowed it to serve these requirements across multiple destinations and property providers. A significant expansion phase began in 2016. In May, SilverDoor acquired Citybase Apartments, strengthening its United Kingdom position. In November of the same year it opened its first international office in Singapore. The overseas office marked a transition from a primarily United Kingdom-based specialist into a business with a more explicit international operating footprint. In December 2017 SilverDoor became part of Habicus Group, alongside sister brands including Citybase Apartments, Central London Apartments and Orbital Partnerships. This group structure placed SilverDoor within a wider collection of accommodation and partnership businesses. It also coincided with broader activity in the corporate-housing and serviced-residence sector, including developments involving Synergy Global Housing and The Ascott Limited. SilverDoor continued building regional infrastructure. In January 2019 it opened an Americas headquarters in Denver. The company later expanded its North American capabilities through its September 2021 acquisition of The Apartment Service, described as a rival serviced-apartment agent. The transaction added scale and market coverage at a time when corporate accommodation providers were serving increasingly international mobility and business-travel programmes. In April 2022 SilverDoor opened Iberia and Latin America headquarters in Madrid. The business subsequently maintained a network of offices and operations in Europe, North America, Asia, the Middle East and India, with locations cited in London, San Francisco, Seattle, San Diego, Denver, Houston, New York, Dublin, Lancaster, Madrid, Dubai, Bangalore, Hyderabad, Singapore and Shanghai. The company’s public profile has also been shaped by industry awards. It was recognised by The Sunday Times 100 Best Small Companies to Work For in 2012, 2013 and 2015, and received awards from relocation, expatriate-management, business-travel and serviced-apartment organisations. Recognition in later years covered corporate-housing provision, marketing creativity, account management, service excellence, crisis management and technology innovation. In particular, a carbon-calculator initiative was recognised in 2024, indicating an effort to give sustainability data a more visible role in accommodation management. In 2024 SilverDoor unveiled a new global headquarters at Chiswick Park and opened a Middle East headquarters in Dubai. In 2025 it celebrated its 25th year in the industry. That year it also announced a merger with Synergy Global Housing. The supplied reference describes the businesses as integrating under the SilverDoor brand in April 2026, with one technology ecosystem and unified team. The detailed ownership, governance and operational consequences of that integration require confirmation from up-to-date company sources.
