Use the protected architect title through a verified appointment
In the UK, the title “architect” is protected when used in business or professional practice. This page is an intake route for defining a project. It does not state that Hampstead On Demand, its operator or every person involved is registered as an architect. Where an architect is required, identify the named individual and check that person on the public Architects Register. Confirm the contracting practice and appointment before instruction. A practice name or service label does not replace verification of the individual. Other designers may lawfully provide some design services but should not be described using the protected title unless entitled to it. The first decision is who is being appointed, which deliverables fall within their appointment and where professional responsibility sits.
Translate the client aim into a testable design brief
A useful architectural brief states the property, tenure, occupants, intended use, priorities, constraints and decisions the design must support. Include existing plans, surveys, title or lease documents, planning history and the budget boundary. Note any fixed event that matters to the client without turning an aim into a promised outcome. List spaces to retain, alter or add. Record qualities such as daylight, privacy, storage and accessibility in practical terms. The architect can then propose the surveys, options and approvals work appropriate to the appointment rather than beginning with an assumed solution.
Define stages, deliverables and decision gates in the appointment
“Draw plans” does not define an architectural service. The appointment should identify the stages included and the output at each one. Outputs may include measured information, feasibility options, planning drawings, technical information, tender material or construction-stage review. It should name the client approvals needed to move forward and the information supplied by others. Excluded services, revisions, expenses, intellectual-property terms and termination provisions also matter. A drawing prepared for planning should not be treated automatically as construction information or a complete specification for contractor pricing.
Establish the status and limits of existing information
Existing drawings, estate-agent plans and historic approvals may be useful but can be incomplete or inaccurate. The architect’s appointment should state whether a measured survey, topographical survey, condition record or specialist investigation is included and to what level. The client should disclose known defects, previous structural work, restrictions and records. Assumptions need to be visible on drawings and revisited when better evidence arrives. Concealed construction, drainage, boundaries or ground conditions can affect feasibility. Where they do, identify the right consultant or investigation rather than absorb the issue into an architectural image or unqualified site observation.
Separate planning, listed consent and Building Regulations
Architectural design may support several approval routes, but no appointment can guarantee an authority decision. Planning permission considers planning control; listed-building consent protects relevant significance; Building Regulations address functional requirements; party-wall and freeholder processes remain separate. The scope should say which applications, supporting statements, consultations and responses are included, who pays fees and who acts as applicant or agent. Conditions, amendments and discharge work should be addressed explicitly. Construction should not proceed from a planning set where technical compliance, structural design or other permissions remain unresolved.
Coordinate specialist design without blurring responsibility
The architect may need information from a structural engineer, building-services designer, interior designer, surveyor, planning adviser, heritage specialist, principal designer or other consultant. The responsibility schedule should define who designs each element and who coordinates geometry and interfaces. It should state which consultant remains responsible for each output. Interior selections do not replace structural or statutory design. Engineering calculations do not resolve planning composition or room use. The client must understand which consultants are appointed directly and which may be appointed by another party. The schedule should also explain how design changes are communicated across current documents.
Choose the procurement and construction-stage boundary
A client may seek competitive pricing, negotiated construction or another procurement route. The architectural appointment should state whether tender queries, comparison, contract administration, site visits, review of submissions, change control or certification are included. Occasional site observation is not continuous supervision and should not be described as a guarantee of workmanship. Contractor design portions and substitutions need a review route consistent with the contract and consultant responsibilities. Before construction begins, the client should know who issues instructions, records changes, assesses payment and decides whether further professional input is required.
Close the architectural appointment with an indexed record
At each stage, record the current drawing issue, specification, approvals position, client decisions and unresolved dependencies. The final architectural deliverables should be listed rather than assumed, together with the file formats and permitted use agreed in the appointment. Construction completion may also depend on records issued by contractors, engineers, authorities and specialist installers outside the architect’s control. An organised index helps later maintenance or sale, but it should distinguish design intent from as-built information and mark any item not verified. The handover cannot imply approvals, inspections or professional certification that were not within the appointment.

People Also Ask About Architectural Design Coordination
Is planning permission the same as building regulations approval?▼
No. GOV.UK states that building regulations approval is different from planning permission, and that you might need both. Building regulations cover the construction and extension of buildings, and many alterations, including replacing windows and doors, heating systems, and a bathroom that involves plumbing. Planning permission is a separate decision by the local planning authority. Holding one consent does not remove the need for the other; both are confirmed for the exact address.
Source: Building regulations approval: when you need approval, GOV.UK
What is a Design and Access Statement?▼
GOV.UK describes it as a concise report accompanying certain planning applications and applications for listed building consent. It explains how the proposal responds to the site and its setting, and how it can be accessed. In England it is required for major development, for listed building consent, and for development in a conservation area or World Heritage Site that is a dwelling or creates 100 square metres or more of floor space. Whether a site is in a conservation area is confirmed for the exact address. The level of detail should be proportionate to the complexity of the application.
Source: Making an application, Design and Access Statement, GOV.UK
Do internal alterations to a listed building need listed building consent?▼
They can. GOV.UK states that listed building consent is a separate regime from planning permission, and that any works to alter or extend a listed building in a way that affects its character as a building of special architectural or historic interest require consent, whether or not planning permission is also needed. Unless the list entry says otherwise, listing covers the entire building, internal and external. Carrying out such works without consent is a criminal offence. The list entry is checked for the exact address.
Source: Historic environment, heritage consent processes, GOV.UK
What does a lawful development certificate for proposed work confirm?▼
Under section 192 of the Town and Country Planning Act 1990, a local planning authority can certify that a proposed use or operation would be lawful for planning purposes. GOV.UK explains that once granted, development in accordance with it must be presumed lawful unless there is a material change before the work begins, such as an article 4 direction withdrawing the relevant permitted development right. The certificate does not remove the need to comply with building regulations or listed building consent at the exact address.
Who holds the CDM client duties on a domestic home project?▼
On a domestic project, HSE guidance states that CDM 2015 client duties normally pass to the contractor on a single-contractor job, or to the principal contractor where there is more than one contractor. If the domestic client has appointed a designer on a multi-contractor project, they can ask that designer to take on the client duties instead, but only with a written agreement. Without that agreement, the client duties stay with the principal contractor. HSE defines a designer as anyone who prepares or modifies designs, drawings or specifications.
Source: Domestic clients: roles and responsibilities, CDM 2015, HSE
What must a planning application say about heritage assets?▼
GOV.UK planning practice guidance states that applicants are expected to describe the significance of any heritage assets affected, including any contribution made by their setting. The description should include analysis of that significance and, where relevant, how it has informed the proposals. The level of detail should be proportionate to the asset’s importance and no more than is sufficient to understand the potential impact. Whether an address is listed or in a conservation area is confirmed from the relevant registers, not inferred from a postcode.
