Halston provides architectural and interior architecture services across six specialist offerings: residential architecture, interior architecture, heritage renovation, hospitality interiors, home staging and property styling, and material consultation. The studio is based in Berlin and Hamburg and works with private and institutional clients across diverse markets.

Project timelines vary by scope and complexity. A private residence typically runs 24 to 36 months from initial brief to handover. A heritage renovation runs 18 to 36 months depending on consents. An interior architecture project runs 6 to 18 months. Home staging engagements run 1 to 4 weeks. Material consultations run 2 to 6 weeks. We provide a detailed programme estimate after the initial project consultation.

Every engagement begins with an initial consultation, in person or online, to understand the brief, the site, and the client's ambitions. From there, we prepare a tailored proposal covering recommended scope, fees, programme, and team structure for approval. We can begin work once the appointment is signed and the initial fee is settled.

Yes. Halston is based in Berlin and Hamburg and works with private and institutional clients on projects in diverse international markets. We coordinate with consultant partners on site as required, and international projects are run from the office closest to the project location.

Our design process moves through six clearly defined stages: initial brief and site analysis, concept design, developed design, technical design, construction stage administration, and post-completion review. Each stage concludes with a formal sign-off meeting and a deliverable that the client approves before the next stage begins. The full process is described in our practice handbook, which is shared with every client at engagement.

Yes. Planning permissions, listed building consents, and the broader heritage and statutory approvals form part of our standard architectural service. We coordinate directly with local planning authorities, heritage offices, and specialist consultants including planning consultants, heritage advisers, and ecology surveyors. On projects outside our home markets we work with locally licensed planning consultants where required.

Halston works on projects from approximately 80 m² (a substantial private apartment or single-room interior architecture) through to 1,500 m² (a fully bespoke private residence or substantial heritage renovation). Our typical residential project is 200 to 600 m². We are selective about smaller projects and accept them only where the brief and client relationship justify the studio's full engagement. Home staging engagements are sized per residence.
