SY Design Studio provides professional architectural design, planning drawing and Building Regulations services in Richmond upon Thames. Led by Architectural Technologist Salman Yousaf, we help homeowners, landlords and developers with extensions, loft conversions, measured surveys, planning applications and detailed technical drawing packages.
Richmond upon Thames is one of London's most heritage-sensitive boroughs, with a large number of conservation areas and listed buildings along and near the river. SY Design Studio provides architectural design and technical drawing services to homeowners, landlords and property owners across the borough, working on period terraces, riverside properties and larger detached houses in areas such as Twickenham, Teddington and East Sheen.
Common projects in Richmond include rear extensions, loft conversions and internal alterations, usually requiring particular care with material choice, roofline and window detailing since the council places significant weight on preserving townscape character. Permitted development rights are frequently restricted in conservation areas, so we recommend confirming a property's designation before any design work begins.
Every property and planning history is different, so we assess each site individually. We cover Richmond, Twickenham, Teddington, Whitton, Hampton, Barnes, Kew, East Sheen, Mortlake and Ham, and the wider West London area.
People searching online for architects near me or architectural services near me in Richmond are often looking for support with planning drawings, Building Regulations packages, extensions or a measured survey for a period property. SY Design Studio provides these services from initial assessment through to technical drawings, working with clients across Richmond, Twickenham and Teddington.
Led by Architectural Technologist Salman Yousaf, the studio offers clear, practical and buildable design solutions for extensions, loft conversions and internal alterations, with particular care given to heritage-sensitive sites. We are happy to discuss your project and the likely planning route before you commit to anything.

Learn MorePlanning applications in Richmond are assessed by the London Borough of Richmond upon Thames. Depending on the property and proposal, a project may require householder planning permission, listed building consent where relevant, and permitted development where a property is not affected by conservation-area or Article 4 restrictions.
The correct route depends on the property type, site location, proposed dimensions, planning history, previous planning conditions, conservation-area or listed-building status, permitted development restrictions, Article 4 Directions, use class and local planning policy. We do not guarantee approval and have no special relationship with any local planning authority — every application is assessed on its own facts.
Large parts of Richmond sit within conservation areas, and many properties near the river are listed or locally listed. Design quality, materials and roofline receive close scrutiny, and permitted development rights are frequently restricted. Some areas may also be affected by flood risk given the borough's riverside location. These designations must be checked for the individual address before design work begins.
Sensitively designed rear extensions, loft conversions and internal alterations are the most common projects in Richmond's period and riverside properties, with an emphasis on materials and detailing that respect the surrounding townscape.
Planning permission and Building Regulations are separate processes. Gaining planning permission, or confirming permitted development, does not remove the need for a compliant technical drawing package before and during construction. Depending on the project, this may include:
Not every project needs every item — the exact package depends on the project, and we confirm the scope once the design is settled.
We follow the same clear process for every Richmond project, from initial consultation through to construction support.
Discuss the property, proposed work, required services and likely next steps.
Review the property type, planning history and potential planning constraints.
Carry out a measured survey and prepare accurate existing drawings where included.
Develop the proposed plans and external design with the client.
Prepare the required drawings and supporting documents and submit the application where included within the agreed service.
Prepare the technical drawing package and coordinate structural and specialist information where required.
Provide clarifications, revisions or further design services where included or separately agreed.
