When most homeowners think about building an annexe or garden room, spring and summer naturally come to mind. Warmer weather and longer days feel like the obvious starting point. However, from a specialist planning perspective, winter is often the most strategic and least stressful time to begin the process.
Starting early gives you greater control over design, planning permission, and build timelines, setting your project up for success well before peak season begins.
Get Ahead of Spring Build Demand for Annexes and Garden Rooms
Demand for annexe and garden room construction rises sharply in spring. Builders, suppliers, and garden room manufacturers typically have their schedules booked months in advance.
Beginning the specialist planning process in winter allows you to:
• Secure preferred contractors for annexe or garden room construction
• Avoid long lead times for materials and material suppliers
• Plan calmly without competing against peak-season demand
By the time spring arrives, your annexe project is already well-positioned rather than delayed.
Planning Applications Take Time
Whether you are proposing an annexe, a garden room, or ancillary accommodation for family use, planning permission is rarely instant. Most applications take 8 weeks or longer, and this can extend if further information or amendments are required.
Submitting your application in winter means:
• Your annexe or garden room application is already progressing while others are still preparing
• Decisions are more likely to be issued before the busy summer period
• You reduce the risk of seasonal council backlogs affecting your timeline
This is where specialist planning advice makes a real difference, ensuring applications are robust and well-prepared from the outset.
Avoid Last-Minute Pressure With Specialist Planning
Spring brings increased pressure on councils, consultants, and builders alike. Starting the specialist planning process in winter helps you avoid unnecessary stress.
Early preparation helps to:
• Prevent rushed annexe or garden room submissions
• Reduce the likelihood of delays caused by overburdened councils
• Create a smoother transition from planning approval to construction
A well-planned annexe project in winter is far more likely to deliver a straightforward build in summer.
