Timing is everything when it comes to building a timber frame extension. A small extension should be finished in six to eight weeks, whereas a medium or large extension could take anywhere from 10 to 12 weeks. However, this can be delayed if unforeseen circumstances occur such as poor weather. The table below will give you an idea of what to expect. After all, no extension is built overnight and you should be aware of the timescales before you start your project!

Compared to traditional methods, timber frame extensions are often cheaper to build. This is because they take less time and use less labour, and because the weather doesn’t affect the construction process, they are more likely to be water-tight. They can also be completed on time, which means fewer missed days. Timber frame construction is also more predictable than most other construction methods, meaning that the price you pay can be set accordingly.

Using ordinary construction timber to build a timber frame extension is not recommended for large expanses of glazing. For these, you must opt for fire-resistant timber and lining. Your architect will know what materials are crucial, and the building control office will be able to identify these before giving you the go-ahead. A timber frame extension will also be cheaper to build than a masonry building, and the whole process will take less time.

If you are going to do the extension yourself, you should get several quotes from tradesmen. Check their work to ensure they are qualified and have the skills to carry out the work. A builder should be able to visit your property, assess the project, and give you an estimate of what your timeframes will be. Depending on the materials used and the size of your project, you can get the job done quicker.


While the materials used for timber frames are similar throughout the UK, the cost of timber frame extensions will depend on the type of extension that you are considering. A kitchen extension, for instance, will require additional timber and wiring. Additionally, you’ll need to account for drainage and plumbing. Different types of timber frame extensions will require different methods for installation and roof structures, so make sure that you’re aware of what each type of timber frame extension includes.

If you’re planning a loft extension, timber is a great option because it’s lightweight and is less susceptible to weather conditions, which can delay traditional methods. Additionally, timber can be erected quickly and easily off-site, making it easier to construct and assemble than masonry structures. Another advantage of timber is its lower cost and shorter construction time. Once you’ve figured out what kind of extension you want, you can talk to your architect about the costs and the timeframe.

Depending on the type of timber frame extension that you decide to build, you’ll have a variety of options for finishes. You can choose a timber render finish, breather membrane, or brick skin. Some people like to have their home’s exterior matched with the existing house by using a brick skin. Whether you choose timber or brick, it’s all up to you and your tastes. You should consider all of these options when deciding which one is right for your property and your budget.

Before undertaking any building work, check with your local authority to ensure that you meet their building regulations.

If you’re looking to add space to your home, consider building a timber frame extension. These extensions are generally less prone to the elements. A timber frame extension will typically be weather-tight in a shorter period of time than a similar build using another material. In addition, timber frame extensions are often more affordable than other types of extensions. However, you should consider the pros and cons of each type before deciding to build one.

A post and beam timber frame is a traditional method, which leaves some of the structural elements visible, such as the upright posts and ceiling joists. This type of timber frame is often mixed with panels made of insulating timber. The latter is also often used in low-rise raisings, where a brick skin may be more appropriate. However, some people prefer the look of a concrete block exterior and a brick skin instead of a timber frame.

The cost of a timber frame extension depends on the size of the room and the type of materials used. Depending on the size of the room and the complexity of the extension plan, timber frame building quotes typically range from PS1,400 to PS2,400. Obviously, if you wish to include expensive materials, the cost will increase accordingly. The complexity of the extension and the finish chosen should also be considered. And, of course, your budget should be flexible enough to accommodate all of your needs.

Timber frame extensions can be added to virtually any kind of UK home. They can be two-storey, wraparound, or single-storey ground floor extensions. Whatever your home’s style, a timber frame extension is likely to fit the bill. It is also an excellent choice for environmentally-conscious homes. So, what are the benefits of a timber frame extension? In general, the benefits of a timber frame extension are similar to those of a brick extension, and they are both beautiful and environmentally-friendly.


Timber frame extensions require expert groundworks. Improperly prepared foundations could fail to support the full weight of a timber frame. The right foundations will depend on the size, location, and type of soil. A building inspector can recommend the right foundations based on these factors. Groundwork for a timber frame extension is vital to ensure that the finished product is safe and secure. To help with the process, here are a few tips.

Choosing the right company for your project is crucial. Some of the best companies will do both the groundwork and timber frame construction.

Groundwork is essential for a timber frame extension because it makes the entire structure weather-tight in a short amount of time.

Timber frame extensions can be built on the first floor or at the top, either upwards or downwards. Timber frame extensions are the most common choice for a home extension, but you can also get creative and add quirky details. A timber frame extension will fit perfectly into any style of UK home. The cost is significantly lower than a blockwork project and can be a great choice for people on a budget. Once you have decided to go for timber frame, you should consider getting planning permission.

Planning permission

Timber frame extensions can be an attractive and eco-friendly way to extend your property. However, obtaining permission from your local planning authority can be a lengthy process. As a result, you should be sure to research planning requirements for building work before you begin. Using a reputable building company can help you through the process. You should also check whether the extension will require a listed building consent or a Certificate of Lawful Use.

Typically, timber frame extensions are built to the rear of properties. While they can be used for any purpose, they may not be the most suitable choice for bedrooms. They are often heavy with glazing and can be cooler than most people find comfortable. It’s therefore best to check with your local planning office before deciding to go ahead with the construction. You’ll need to make sure that your proposed timber frame extension is not overly ambitious.

If your home falls within one of these categories, you can start the planning process for the timber frame extension. Before getting any quotes, make sure that you discuss the plans with your neighbours. You should let them know what work you’re planning and when they should expect disruption. Also, remember to check if any protected areas are in the area. You may be within a national park or conservation area. Article 4 directions might prevent you from building near the boundary.

Whether you choose a timber frame extension or a steel one, you’ll need to get planning permission. Whether you are planning to build a new home or add an extension to your existing property, a timber frame extension is a great way to increase the value of your property. Just make sure you’re clear about the requirements and don’t get hung up on the legalities. If you have any concerns or queries, talk to a qualified builder.
