So you’re thinking of upgrading the garden and looking for ideas. Most structures, as long as they are less than 4m in height can be build under permitted development and we are happy to advise on your situation.There are many different materials that can be used to create your perfect space, we obviously think that oak is the best option.Traditional oak timber-frame buildings in the UK have lasted hundreds of years with minimal structural degradation and many have become Listed buildings.A softwood Shed (e.g., pine, spruce, fir) has a typical lifespan:•Untreated softwood: 5–10 years•Pressure-treated softwood: 15–25 years•High-quality cladding + good maintenance: maybe 25–30 yearsVulnerable to:•Rot if ground moisture rises•UV degradation•Warping and movement•InsectsWhether it is a potting shed or a swimming pool cover, the benefits of using oak are great and often not as expensive as people think.1. Timber Options•Oak (Hardwood)Very long-lasting (80–200+ years)Premium cost, beautifulLow maintenanceOak is a hardwood with high natural resistance to:•Rot and decay•Insects•Moisture•Softwood (Pine, Spruce, Fir)CheaperLifespan 10–30 yearsNeeds regular treatment•CedarNaturally rot-resistantSmells great, stable, lightweightLifespan 30–50 yearsMore expensive than softwood, less than oak•LarchDurable softwood, similar lifespan to cedarGood for cladding or full buildings2.
