However, we always recommend discussing your plans with them early on. A friendly conversation can help prevent misunderstandings and make the process smoother for everyone involved, particularly in close-knit or conservation areas. We generally find that neighbours are happy to see a beautiful oak frame even if its in view as they are far more aesthetically pleasing than modern buildings.

Both these materials look almost identical to oak after oxidising/ ageing.

This ensures compliance and safety standards are met without compromising the appearance or craftsmanship of your building.
- [What type of glazing system is used in green oak frames?](https://greenoakbuildingcompany.co.uk/faqs/what-type-of-glazing-system-is-used-in-green-oak-frames/): We use face (direct) glazing for all our green oak frames. This method not only secures the glass but also encapsulates the frame, offering reliable weather protection and allowing for the natural movement of green oak as it seasons. It’s a trusted approach because it preserves the traditional appearance of oak framing, protects both the structure and the glazing system from movement-related stress, and helps keep the internal frame dry for long-term durability. Maintenance is minimal, and if the external cover boards ever need replacing, they can be changed easily without affecting the structural frame.
- [Can you build from my own design plans?](https://greenoakbuildingcompany.co.uk/faqs/can-you-build-from-my-own-design-plans/): Yes. Virtually any design can be brought to life, whether based on architectural plans, sketches, or photographs. You can choose to recreate a period-style barn, build a modern garden room, or design something completely unique. Skilled craftsmen will ensure that every detail meets both your aesthetic and structural requirements.
- [How do you determine the proportions of your oak frames?](https://greenoakbuildingcompany.co.uk/faqs/how-do-you-determine-the-proportions-of-your-oak-frames/): Each oak frame is designed with balanced proportions that combine visual harmony and structural strength.

This process guarantees that your building is both elegant and robust.
- [Are your doors and windows always made from oak?](https://greenoakbuildingcompany.co.uk/faqs/are-your-doors-and-windows-always-made-from-oak/): Doors and windows are often crafted in oak for its strength, beauty, and timeless character. However, other timbers can also be used if you have particular requirements or a preferred aesthetic. You can discuss your ideas with the design team to find the most suitable timber for your project.
- [Do you produce only standard joinery sizes?](https://greenoakbuildingcompany.co.uk/faqs/do-you-produce-only-standard-joinery-sizes/): No. Every piece of joinery is made to order, allowing for any size, style, or design. Whether you want a specific window shape, a set of oversized doors, or even a frame inspired by a photograph, the design can be fully customised to match your building and personal preferences.
- [What type of foundation is needed for an oak framed structure?](https://greenoakbuildingcompany.co.uk/faqs/this-is-faqs-for-construction/): The type of foundation required depends on your site conditions and the scale of your project. A thorough site assessment determines the most suitable option, whether that’s a concrete slab, strip foundation or an engineered solution such as a raft or piled foundation. The right foundation ensures long-term stability, proper weight distribution, and lasting structural integrity for your oak framed building.
- [Is the oak cut and built directly on site?](https://greenoakbuildingcompany.co.uk/faqs/is-the-oak-cut-and-built-directly-on-site/): The oak is crafted off site in a dedicated workshop, where every frame is cut, jointed, and pre-assembled using traditional joinery techniques. This ensures precision and consistency before delivery. Once the components are complete, they are transported to your site and assembled quickly and accurately, reducing disruption and ensuring the highest standards of quality.
- [How are oak garden structures assembled?](https://greenoakbuildingcompany.co.uk/faqs/how-are-oak-garden-structures-assembled/): Oak frame garden structures are assembled using traditional mortice and tenon joints secured with draw dowels for strength and durability. If we use mechanical fixings, they must be stainless steel to prevent corrosion caused by the natural tannins in the oak.
- [Can you incorporate utilities such as water and electricity?](https://greenoakbuildingcompany.co.uk/faqs/can-you-incorporate-utilities-such-as-water-and-electricity/): Yes, water and power can be integrated into your oak framed building. Lighting, heating, and plumbing can all be incorporated to suit your intended use, whether it’s an oak garden room, garage, office, or barn. The layout can be planned around your needs, creating a functional and comfortable space that fits perfectly with your lifestyle.
- [Do you handle site waste and rubbish removal after completion?](https://greenoakbuildingcompany.co.uk/faqs/do-you-handle-site-waste-and-rubbish-removal-after-completion/): A skip is normally required for the disposal of building waste. If a skip is not available, all surplus materials and waste will be neatly stacked on site, ready for you to use or remove as you wish. This approach ensures a tidy finish and allows you to repurpose any leftover oak or timber if desired.
- [How much does an oak framed building cost?](https://greenoakbuildingcompany.co.uk/faqs/this-is-faqs-for-costs/): The cost of an oak framed building depends on several factors, including size, design complexity, and chosen materials. A detailed quotation is provided following an initial consultation so you know exactly what to expect. This ensures your estimate accurately reflects your individual requirements and the level of craftsmanship involved in your project.
- [How is payment structured?](https://greenoakbuildingcompany.co.uk/faqs/how-is-payment-structured/): A fixed quotation is provided once the design is agreed. A deposit is required before construction begins to secure materials and timber. After that we have a stage payment system that means you only pay a payment once a pre-agreed stage has been reached for example oak frame stood on site, or glazing complete.
- [What design factors influence overall cost?](https://greenoakbuildingcompany.co.uk/faqs/what-design-factors-influence-overall-cost/): Several design choices can influence the overall cost of your oak framed building. Factors include frame style, building size, type of timber, glazing, and cladding. Site access, boundary positions, and fire protection requirements may also play a role. By discussing your budget early, you can make informed design decisions that balance aesthetic appeal with cost-efficiency.
- [Does your quote include all assembly costs such as crane hire?](https://greenoakbuildingcompany.co.uk/faqs/does-your-quote-include-all-assembly-costs-such-as-crane-hire/): Yes, assembly prices include the cost of plant and lifting equipment needed to raise the oak frame, including crane hire. Some companies exclude these costs and add them as extras later, but your quote will include everything necessary for assembly unless you chose not to. This ensures full transparency and prevents unexpected charges once construction is underway.
- [Are there any hidden charges not shown on my quote?](https://greenoakbuildingcompany.co.uk/faqs/are-there-any-hidden-charges-not-shown-on-my-quote/): There are no hidden costs. The only potential changes would occur if you decide to alter your design, if deeper foundations are required by Building Control, or if temporary site access is needed that wasn’t originally included. Any variations are always discussed and agreed upon before work continues, ensuring complete clarity throughout your project.
- [How long does an oak framed building project usually take?](https://greenoakbuildingcompany.co.uk/faqs/how-long-does-an-oak-framed-building-project-usually-take/): The timeframe varies depending on design complexity and size. The design and planning stages can take several weeks, while on-site construction generally ranges from a few weeks to a few months. Smaller projects, such as garages or garden rooms, can be completed relatively quickly, while larger or bespoke builds naturally take longer.
- [How long does it take to assemble the frame?](https://greenoakbuildingcompany.co.uk/faqs/how-long-does-it-take-to-assemble-the-frame/): That depends on the size and type of structure. A standard extension typically takes around one day to assemble, while a medium-sized house frame usually requires about seven to ten days. Larger or more intricate frames may take longer, but each project is planned carefully to ensure efficiency and precision.
- [What is the best way to care for an oak framed building?](https://greenoakbuildingcompany.co.uk/faqs/this-is-faqs-for-maintenance/): Oak requires very little maintenance thanks to its natural durability. Cladding will weather beautifully over time and can be treated for a particular finish if desired. Doors and windows may benefit from occasional oiling to preserve their colour, but beyond this, your oak frame will age gracefully without the need for regular upkeep.
- [Is the oak treated before use?](https://greenoakbuildingcompany.co.uk/faqs/is-the-oak-treated-before-use/): Oak’s natural strength means additional treatment is not necessary. Softwood components, such as rafters, are pressure-treated to protect against the elements. Some owners choose to oil their oak for appearance, but this is purely aesthetic. The wood’s natural tannins act as a preservative, keeping the frame strong and resilient for years to come.
- [Do I need to protect my oak frame against woodworm or rot?](https://greenoakbuildingcompany.co.uk/faqs/do-i-need-to-protect-my-oak-frame-against-woodworm-or-rot/): Modern oak frames rarely suffer from problems such as woodworm, damp, or rot. The timber used is carefully prepared, with almost all sapwood removed to eliminate any potential food source for insects. Good ventilation and proper detailing prevent moisture build-up, while oak’s high tannin content provides excellent natural protection against pests and decay if you do notice wood worm at any time it can be treated easily and cheaply at any time.
- [How should I clean my oak frame?](https://greenoakbuildingcompany.co.uk/faqs/how-should-i-clean-my-oak-frame/): Oak frames can be cleaned using sanding, oxalic acid washing, or specialist blasting. Sanding and acid cleaning can be done yourself with proper safety precautions, while blasting should be carried out by professionals. Always follow safety guidance and test any cleaning method on a small area or preferably an off cut before applying it across the frame.
- [What causes black marks on my oak frame?](https://greenoakbuildingcompany.co.uk/faqs/what-causes-black-marks-on-my-oak-frame/): Black marks occur when oak comes into contact with steel or iron during handling or assembly. The natural tannins in the timber react with iron in metal, creating dark stains. These marks are harmless and often considered part of the character of the frame, though they can be removed or lightened if desired using specialist cleaning methods.
