YOUR PINNER PROJECT
A calm place for focused work
For a Pinner garden office, create a clear boundary between desk time and home life. A compact entrance, tidy storage and lighting suited to reading or screen work can help. Discuss whether clients will visit, because that may influence access, facilities and the planning assessment for the proposed use.
Bring a rough garden plan, photographs and a list of what the building needs to do. We can then discuss the position, orientation, access and service connections before narrowing down the layout. A design that works on paper must also work with the route into your garden.
CHOOSE YOUR STARTING POINT
One building. Space for your priorities.
Choose the main use first. It guides everything from glazing and storage to lighting and the electrical layout.
A gym or creative studio
Allow for equipment clearance, movement, ventilation and the way sound may travel to the house and neighbours.
Explore garden gymsFamily space with useful extras
A shared room can combine relaxed seating with storage. A WC or shower can be explored where services and approvals allow.

FROM BRIEF TO BUILD
A clear scope before construction
For your Pinner garden room, resolve the practical details early so the finished space supports the way you intend to use it.
Start with people and purpose
List the furniture, equipment and storage that the room must accommodate. Allow circulation space as well as the footprint of each item.
Understand the garden
Assess delivery access, levels, foundations, trees and boundaries. Map the route for power and any water or drainage connections rather than leaving it to the end.
Agree the specification
Review the SIP structure, cladding, glazing, heating, ventilation and finishes. Confirm approvals, responsibilities, inclusions and the construction programme in writing.
Build and hand over
Coordinate the agreed works and relevant inspections. At handover, review the installation, operating information and documentation applicable to your project.
PLAN WITH CONFIDENCE
Planning permission and building regulations
Some garden rooms used for purposes incidental to the house may fall within permitted development, subject to limits and conditions. The proposed use, dimensions, position and any restrictions on the property all matter. Sleeping accommodation needs a different assessment. Building regulations are a separate question; size alone does not establish an exemption. Confirm both routes for your actual proposal before building.
Check the council responsible for the property's postcode. Conservation designations, protected trees, previous permissions and site constraints can affect the proposal. We can discuss the construction information needed; the authority or appointed building control body determines the applicable approval process.
BUDGET & SPECIFICATION
Price the complete project
A useful budget covers more than the shell. Foundations, access, external works, glazing and the distance to services can change the overall cost. Lighting, heating, sockets and any bathroom or storage element should be included in the brief.
Request a written quotation for your Pinner property, with VAT, inclusions, exclusions and approval or professional fees clearly identified. The programme should reflect site conditions and the agreed approval route.

YOUR QUESTIONS
Garden Rooms in Pinner: useful answers
Can TRJ build a garden room in Pinner?
Yes, Pinner is included in our service area. The first step is to assess your intended use, garden position, access and service routes. A quotation and programme follow the agreed scope and site assessment.
How should I start planning my Pinner garden room?
For a Pinner garden office, create a clear boundary between desk time and home life. A compact entrance, tidy storage and lighting suited to reading or screen work can help. Discuss whether clients will visit, because that may influence access, facilities and the planning assessment for the proposed use.
What affects the cost of a garden room in Pinner?
Floor area is only part of the budget. Ground conditions, foundations, access, glazing, interior finishes and service connections can all change the scope. Ask for a written quotation that identifies inclusions, exclusions, VAT and any approval or professional fees.
Does my garden room need planning permission?
Some garden rooms used for purposes incidental to the house may fall within permitted development, subject to limits and conditions. The proposed use, dimensions, position and any restrictions on the property all matter. Sleeping accommodation needs a different assessment. Building regulations are a separate question; size alone does not establish an exemption. Confirm both routes for your actual proposal before building.
Can I include a WC, shower room or storage?
Yes, these options can be considered. A separate storage zone protects the main room, while a WC or shower needs suitable drainage, water and electrical provision. The site survey and proposed use determine the practical design and approval requirements.
Are the photographs projects in this exact area?
Each photograph is labelled with its real project location. The images show completed work from the TRJ portfolio as design inspiration; they are not presented as projects in this area unless the caption says so. Work undertaken for Garden Spaces is credited alongside the relevant example.
