What do People Use An Oak Annex For?

One of the main reasons more and more people are choosing oak annexes is that they can be utilised in so many different ways. Irrespective of whether you are looking to expand the overall footprint of your property, increase your living space or give yourself a haven where you can relax away from the rigours of daily life, a bespoke oak annex can be tailored to suit your exact requirements. Here are some of the different uses for an oak annexe. 

Home Offices

As more and more employers move towards remote and hybrid working, having a dedicated work space at home is now more valuable than ever. An oak annex makes an ideal home office as it provides you with a peaceful, professional environment which is a world away from the distractions you face working at the kitchen table. The natural warmth and charm of oak beams make your workspace not only functional but inspiring, which in turn helps to boost productivity. 

Personal Gyms and Wellness Spaces

As people's work lives become busier, finding time to go to the gym can sometimes be challenging. So, imagine if you had your work out space just a few steps from your back door. An oak annex is the perfect choice if you are considering a home gym, yoga studio, or wellness retreat. Features such as  large windows, bi-fold doors, or open-plan interiors can give your personal workout space a bright, airy, feeling making it ideal for early morning workouts or evening relaxation. The natural insulating properties of oak also help regulate temperature, making the space comfortable year-round.

Multi-Generational Living & Granny Flats

With families increasingly seeking ways to accommodate elderly parents or adult children who may be saving up for a home of their own, an oak annexe offers you the ideal solution for multi-generational living. A self-contained oak annex, often referred to as a granny flat, provides your nearest and dearest with independence and comfort while keeping them close at hand. Our annexes can be fitted out with  living areas, kitchens, bathrooms, and bedrooms, all built to your exact specifications. 

Guest Accommodation

Having the ability to provide visitors with their own private space is something that definitely  doesn’t go unnoticed. An oak annex can make the perfect guest suite, giving friends and family a comfortable, self-contained place to stay. Whether your preference is for a simple en-suite bedroom or a fully self contained guest lodge, an oak framed annex will guarantee your guests feel relaxed and at home. Another significant benefit of a guest annex is that it also gives you the privacy you don’t always get when you have visitors.

Adding Value to Your Home with an Oak Annex

Why Choose Oak Frames for Your Annex?

Oak has been used in construction for centuries—and for good reason. It combines unmatched strength with natural beauty, resulting in a building material that is as functional as it is striking. Here are just a few reasons why oak is the ideal choice for your annex:

Timeless Aesthetic Appeal: Oak adds warmth, character, and a traditional charm that complements a variety of architectural styles, from modern builds to heritage homes.

Strength and Durability: Oak’s dense grain and natural resilience mean it can withstand the elements, resist decay, and remain structurally sound for many years to come. 

Sustainability: At Oak By Design, we source oak responsibly, ensuring your annex is environmentally friendly and ethically produced.

Low Maintenance: Once treated, oak is naturally resistant to pests and weathering, requiring minimal upkeep to maintain its beauty.

Oak Annexes can be Customised: Oak frames are highly adaptable, allowing for a range of designs, from open vaulted ceilings to partitioned rooms and large glazed openings.

FAQ'S

The cost of an oak annex is typically influenced by a number of key factors, including size, complexity of the design, the standard of the interior fit-out (such as kitchen, bathroom, and heating), the quality of materials used, and the site conditions (like groundworks or access restrictions). Custom features like large glazing, additional rooms, or architectural detailing can also increase costs. Planning and building regulations, as well as location-based labour rates, may further affect the overall price.
Oak annexes offer a blend of durability and aesthetic appeal. The natural timber provides a warm, rustic charm that integrates beautifully with gardens or rural settings. Additionally, oak is a sustainable material with excellent insulation properties, and oak frames are quick to assemble, often reducing construction time compared to traditional brick extensions.
With proper care and maintenance, an oak annex can last for several decades, often over 100 years. Oak is a strong, naturally weather-resistant hardwood that continues to harden over time, making it exceptionally durable. Regular inspections and minor upkeep like oiling or treating the wood can help preserve its longevity and appearance.

As the owner of a local joinery business, Robert Davis Joinery, I have had the pleasure of using Oak by Design on several occasions over the last 8 years. They have produced bespoke interior products for me including Oak doors and timber moldings. The staff in the office and the workshop are always very helpful and friendly and the standard of the workmanship and materials are always of a very high quality.

Oak by design were a fantastic company to deal with. They made us some treads for a bespoke stair case from large pieces of air dried oak. They were very thorough in making sure that they understood exactly what we wanted. They made excellent suggestions for small changes to our own design in order to produce a better finished product and to manage the cost. We were very happy with the treads when they were delivered. They look fantastic and fitted perfectly to the steel frame which was made by a third party. I could not recommend them more highly.

Thank you Jo for your assistance and detailed guide every step of the way with my new porch. Very pleased with the finished product, I would highly recommend Jack and his team for installation

Oak by Design have made 2 oak framed rooms for us, sunroom at the front and and "moonroom" (photo) at the back which encompasses a shower room, work area and storage. They have been helpful at every stage and the outcome is simply brilliant. They make the whole house feel roomier and brighter and are beautiful places to be. GE North Yorkshire

Thank you Oak by Design for my gorgeous… Thank you Oak by Design for my gorgeous oak porch. From my first contact with your company and speaking with Amanda the service has been first class. The quality of the oak and the design of the porch was just what I wanted. Manufacture and delivery were well communicated and delivered to site for our builder on time and to fit in with the building works. Your finishing touches and added extras made our porch very unique to our home. I have had lots of compliments on the enhanced look it has made to our property and our builder is full of praise about the quality and the ease of construction on-site. Thank you so much Amanda & all the team at Oak by design.

We worked with the team who designed a wonderful porch for our house near Harrogate. It has been an amazing addition. Simple but effective - excellent craftsmanship using authentic materials. We are absolutely delighted with the transformation and everyone who sees the porch says how great it looks. Thanks to all the team at Oak By Design.

We got a fantastic garden structure from Oak by Design. It is a very handsome building and the design process was very patient, to say the least. We didn’t really know what we wanted, so we had to be guided through it. And we are delighted.

Amazing customer service from beginning to end . My builder was in awe at the quality of the oak porch components. Call them and ask for Joanne - what she doesn’t know isn’t worth knowing! It’s not every day you invest in a “proper” porch so do it right. You’ll definitely be delighted!

From start to finish Oak By Design have been incredible, nothing was too much trouble. Our new Oak doors are beautifully made and have really been the icing on the cake to finish our house renovations off. We have also had a fabulous outdoor oak structure with heating and we are very much looking forward to making the most of it in the months ahead. Thank you to the whole team I would throughly recommend.

Ordered an oak mantle beam from Oak by Design and they quickly called to check the finer details. Unfortunatly, the beam was slightly damaged on arrival by the courier company. Oak by Design immediately arranged to have it picked by DHL, transferred back to Yorkshire from Kent, repaired and sent back within 2 days, with no quibbles. The beam is beautiful, as is the high quality customer service by these people. Fully recommend using this company. Anthony Slater, Tonbridge. Tonbridge.

Would highly recommend working with Oak By Design and would not hesitate to use their services again for future projects!

Four years ago we took the decision to completely gut an old farmhouse and start again with it, we started looking for a supplier of oak to refit all of the internal doors, door casings, skirting and flooring. Our carpenter recommended Oak By Design. He wasn't wrong! All of the oak has been completely top notch. As the old house has settled into it's new skin it has moved and cracked in various places, the only thing that has been stable and unwavering is the oak. The customer service has been superb, with them continuing to supply exactly the same items, with the same quality over the course of 4 years. They even indulged our designs for furniture for our "boot room", with Shoe pigeon holes and a bench which we could store wellies under (as pictured). The doors supplied by them are reassuringly heavy and sturdy, with a proper "thunk" as you close them, cutting off sound from the rest of the house. There may be other, cheaper suppliers of oak out there, but none with the same level of quality, longevity and customer service as Oak By Design. If you want to do it right (& once!) use these guys.

I was sourcing an oak RSJ cover (circa 5m length) for my extension and found Oak by Design on the internet. All of the reviews I could were glowing and so I contacted them......And I'm so glad that I did. Joanne Fisher answered my initial call and she looked after my order from beginning to end - in terms of ensuring that I got exactly what I wanted she/they provided a superb service - everything on time - delivery in to the Peak District to suit when I wanted. The quality of the the RSJ cover is fantastic thick solid oak that matches my oak floor - looks amazing. If you want anything oak I can thoroughly recommend Oak By Design.

Superb! Fantastic! I can’t recommend enough. If you want gorgeous oak use this company. Oak by design made a porch for us and we couldn’t be more happier with it! It’s beautiful! The quality is first rate. Throughout the build Jo kept us informed as to the process of having the oak cut to size and installed. Jo and the team even sent us a lovely oak chopping board! Jack and his team who built it are fabulous! They go the extra mile. We have decided to use oak by design for a kitchen extension project in the future. Thank you oak by design for giving me a gorgeous porch! Charlie x

We worked with Jamie from Oak By Design on a super project near Wetherby. There was plenty of oak in this design for the team to really show their worth - and they did. The attention to detail was excellent. If anything was not quite how the client wanted it, they were straight back to attend to this. The customer care was superb. We look forward to working with Oak By Design on another project soon.

Fantastic service from start to finish, I would have no hesitation in recommending this company or using them again. Very professional and helpful. Joanne was great in assisting us with choosing both styles and colours of the beams and cladding.

Firstly, the product quality was superb, a beautiful oak mantle piece for my fire place, gorgeous. The installation was quick, efficient and fitter very friendly. The price was very reasonable, actually very good value. But what makes it all SIX STAR, ( but we I can only give 5!), was the customer service. When walking in the shop I was perfectly attended to, I was given samples to take home and they remembered to call soma days later to see what I thought. Order to install time was very fast for such a bespoke service. My experience was world class, great to deal with a brilliant local/small business, I totally recommend.

We are ‘over the moon’ with our beautiful oak porch made by Oakbydesign .From our initial enquiry to delivery and installation the service and attention to detail has been outstanding!

I first used Oak by Design in 2021 for a oak porch, I used them again 2023 for an oak pergola. Both times my clients have been Delighted with the finished product. Both times the product was delivered when stated, everything i needed was on the delivery. Oak by design listened to what I required for both jobs. The quality of the oak is excellent, all joints fit correctly & if I had a problem I only had to ring and speak to them.

My client was looking for ways in which to make his conversion (of an early seventies house into a period family farmhouse) “stand out from the crowd”. whilst maintaining a commercial eye on his expenditure, as the house was being converted for resale profit. Making the choice to meet with Richard and explore possibilities for incorporating some Real solid Oak features into his plans proved to be the making of the project. By taking lots of advice from Richard on both the size and structure of the components we were able to incorporate three key features. The beautiful and bold roof trusses and purlins for the open plan kitchen are simply a joy to behold. The stunning full height gable window which is directly glazed into the large framework can be appreciated from both the the kerbside and of course from within the cosy snug on the ground floor or the amazing first floor main bedroom where we incorporated some additional exposed roof beams just purely for effect. All in all it is fair to say that these significant choices certainly created the wow factor my client was looking for. Having managed to pre sell the property well before completion it in itself demonstrates the benefits of keeping these sorts of real oak features as part of a modern build. I have no hesitation whatsoever is saying that if anyone is looking to get advice and is serious about investing in quality oak products they should have no need to look further than Oak by Design. Thanks again Richard for all your help , guidance and continued support which is a credit to you and the craftsmen you employ.

Oak by Design were extremely helpful at all stages of my project from helping and advising me to choose the most appropriate beam through to advice on fixing the beam. They were extremely patient with changes to my beam dimension requirements finally providing a solution to suit my project. They provided photographs on completion of the beam prior to dispatch to ensure that my requirements had been met. I was extremely impressed by the quality and finish of the beam which has become the focal point for my fireplace project. Oak by Design provided customer care of the highest quality and I would highly recommend their services.

From the moment we visited the Oak Design showroom, we knew that we were dealing with a top quality local company. Richard the owner, showed us around his design works with real pride of his product and service offering. Jamie as sales executive has discussed and agreed the options & design with costs to us and we have now implemented the first phase of our home improvement, with more work to follow. We are highly delighted with the finished product and would strongly recommend Oak Design to other interested clients. I also suggest that you pay them a personal visit at the Home Building & Renovation exhibition in Harrogate, as well as their wonderful showroom of Oak Solutions in Tockwith to get a personal guided tour.

I firstly used oak by design a couple of years ago for an open oak porch. They were extremely helpful and everything was delivered on time to the highest quality. The porch went together with the oak dowels provided and looked great when it was all slated in. They have also supplied me with a oak beam for a fireplace natural random finish and it looks good.

I wish I could give more starts!! We looked at many companies before finally choosing Oak by Design. We are so glad we chose them. They were excellent from start to finish. They worked with us to find a workable design that was to our liking. Our door looks amazing (despite the building site that still surrounds it!). Their customer service is of the highest standard, Joanne could not do enough to help us. I would not hesitate to recommend them.

I could not recommend Oak By Design more highly. Joanne and the team worked tirelessly to resolve an issue that was the result of my mistake when I ordered the porch. Great customer service.

On behalf of John Docherty: Oak By Design were a great company to deal with; helpful, knowledgeable, professional. The quality of the oak supplied to us for our bespoke porch was first class.

What can I say, Oak By Design have been the most fantastic company to deal with. Joanne was so helpful, friendly and professional. She really seemed to care about our project, which made such a difference. We had 4 oak RSJ covers made and 2 fireplace mantles. The finish is outstanding. Everyone believes they are solid beams, which was just what we wanted. The care and attention this company will give you is 2nd to none and I would highly recommend them. Pictures will follow when we complete our project, thanks again Oak By Design. x
