SY Design Studio provides professional architectural design, planning drawing and Building Regulations services in Brent. Led by architectural designer Salman Yousaf, we help homeowners, landlords, developers and commercial clients with extensions, loft conversions, flat conversions, planning applications and detailed technical drawing packages.
Brent is one of London's densest boroughs, covering Wembley, Harlesden and Willesden, with high demand for flat and HMO conversions alongside commercial change-of-use projects on busy high streets. SY Design Studio provides architectural design and technical drawing services to homeowners, landlords, developers and commercial clients across the borough.
Our approved conversion of a former betting shop into seven Class E commercial units on Harrow Road, Wembley, was completed here, reflecting the type of commercial change-of-use work we regularly support in Brent. On the residential side, common projects include rear extensions, loft conversions and conversions of houses into flats, particularly around Wembley, Harlesden and Willesden.
Some parts of Brent carry Article 4 Directions covering HMO conversions, meaning full planning permission is often required rather than relying on permitted development, so we check this for every property before advising on the route. We cover Wembley, Harlesden, Kilburn, Willesden, Neasden, Queen's Park, Kingsbury, Stonebridge, Alperton and Brondesbury, and the wider West London area.
People searching online for architects near me or architectural services near me in Brent are often looking for support with planning drawings, flat conversions, HMO advice or commercial change-of-use projects. SY Design Studio provides these services from initial assessment through to technical drawings, working with clients across Wembley, Harlesden and Willesden.
Led by architectural designer Salman Yousaf, the studio offers clear, practical and buildable design solutions for extensions, loft conversions, property conversions and selected commercial projects, including our completed Class E conversion on Harrow Road, Wembley. We are happy to discuss your project before you commit to anything.

Learn MorePlanning applications in Brent are assessed by the London Borough of Brent. Depending on the property and proposal, a project may require householder planning permission, full planning permission for HMO and change-of-use projects, permitted development, and commercial change-of-use applications.
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.
Brent has Article 4 Directions covering HMO conversions in several areas, meaning full planning permission is often required rather than relying on permitted development. Commercial premises along Brent's shopping parades are frequently considered for Class E subdivision and change of use, as with our completed Harrow Road project. These designations must be checked for the individual address.
Flat and HMO conversions and commercial Class E change-of-use projects are especially common in Brent, alongside rear extensions and loft conversions on the borough's residential streets.
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 Brent 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.
