    We are delighted with our new extension, from the initial design stage Tony listened to our needs and provided sound advice. I would not hesitate to recommend this company, the advice we were given as well as the support throughout was invaluable.

    Cannot recommend highly enough. After our first meeting with Tony we knew we wanted his company to do the work, and we weren’t wrong. From the first spade in the ground to the final sealant finish it’s been a thoroughly satisfying experience. Any questions we had, Tony always made time to answer and explain. Not only were his guys some of the best tradesmen I’ve ever used, they were also polite, friendly and accommodating. Any worries we had about employing builders are now gone because any future work we have, our first call will be to Tony and the Brunstane Group. And the extension is absolutely brilliant!!!

    I am delighted with our new basement conversion which allows us to work safely and care for our 3000 customers per month. A chance discussion with my client Tony has led to a fantastic transformation of my shop. Tony listened and worked with me throughout the project to achieve a great end result. Nothing was too much trouble and the service was excellent. All our customers love our new basement salon and have commented on the excellent workmanship and attention to detail. Overall a great experience and I would recommend the Brunstane Group to anyone looking to extend or convert their home.

Frequently Asked Questions

Extending your home is an exciting prospect, but for many it is quite daunting too—we’ve all heard horror stories shared by those who have gone down that path. It doesn’t need to be that way though. With a little bit of planning, the right advice and some discipline, you can take control of the process and ensure your extension improves your lifestyle for many years to come.

What is the first step?

No matter how big or small, every extension project requires a custom design solution. It is an opportunity to improve the liveability of a house, and a chance to add value to the property. Therefore, it is critical that you get professional help at the design stage of the project, to ensure you get the best possible outcome for your given budget. This should be your first step.

The options in most cases are to engage a building designer or an architect or better still a building company with an in-house architect

What is the purpose of the room?

This is an important and often overlooked question. Too many people get into an extension project without enough clarity about what they are actually trying to achieve.

Your design brief should clearly address these very personal and unique aspects of your life, rather than being a list of random thoughts and ideas you have seen over the years. Clarifying these questions and their answers will help you create a detailed brief, which is also more likely to help you avoid overspending on unnecessary spaces and items.

Do we have enough space to extend?

To answer this question you’ll need to think about what it is you actually need. One extra bedroom may not take up a lot of room, but a new family room and kitchen is a bigger extension that may have an impact on the amount of space you have left in your garden.

Like buying a new sofa, you can start to visualise how much space you might need by using rope or other markers to map out how big the new spaces will take up on your property. A good tip is to use the size of your existing rooms as a guide to how big each room should be.

Maybe we need to go up?

If you don’t have enough space to extend at ground level, you may need to consider going up and adding a second storey. Adding another level is great for retaining external garden space.

How do we make it cost-effective?

One of the most expensive elements of an extension is demolition work, and the knock-on costs that tend to follow.

A major potential cost of demolishing walls is the likelihood that structural modifications will be required if the wall being removed is load bearing. In this case there are several tradespeople involved, structural engineers, builders, joiners, blacksmiths, plasterers and painters.

Although opening up a room can create a wow it can also blow your budget. Take time to chat through the options with an architect/building company at design stage to achieve the best results in the most cost effective way.

Do we need to match the existing house?

One of the exciting things about extending a home is the opportunity to have some fun with the design.

By choosing to adopt a contrasting building style to that of the existing house, you are opening up numerous possibilities for material choice, roof style, use of texture, glazing proportions, ceiling height and much more. Modern materials are better suited to the open-plan living style that we generally desire, enabling more natural light and ventilation, as well as the ability to personalise your colours and finishes.

One of the key considerations when choosing to extend in a contrasting style is to make the change from old to new as deliberate and concise as possible. In contrast you may choose a design that complements your existing house and “looks like it’s always been there from day one”. Whatever route you go, take your time to discuss with an architect before moving forward.

Can we achieve more light?

Understanding where north is will give you a good idea of where the sun will be at different times of the day; and if you have already lived in the home for a while, you will know where the sun will enter the property from season to season. Capturing northern sun should be one of your key priorities when extending, especially if you are adding a living room or family room that you spend a lot of time in. More natural sunlight will make it a much more comfortable space to live in, and will also reduce the amount of artificial heating required.

However, when adding larger windows you must also be very aware of how exposed the windows are to summer sunlight, especially the west-facing afternoon sun. While having sunlight beaming into the space in winter is a lovely outcome, the opposite can be said for scorching hot summer sun as it can make the space unliveable. This is where a thorough understanding of the orientation, appropriate glazing specification and good use of shading elements is critical. Once again, a good architect will help achieve the best results in your circumstances.

Would we need to move out?

The financial benefits of living in the house throughout an extension are obvious, not to mention the convenience of not having to uproot your life and routine. Unfortunately, it may not be that easy. Any extension project that also involves a significant amount of renovation work to the existing part of the house will be very difficult to live in throughout the build. In these circumstances, the project may be able to be staged so that you can move from one part of the house to the next.

But you must also be aware that staging a building project will generally mean it takes longer to build, adding a temporary kitchen for example will cost a little bit more. This extra cost will have to be balanced against moving out costs and the disruption to family life. Everyone's situation and circumstances will differ.

How do I find a builder?

You should choose a builder who is experienced in doing similar work and within similar budgets to yours. Your building company or architect should be a good source of advice, and offer a full turn key service.

How long will it take?

How long is a piece of string? A quick and simple extension might only take 6 - 8 weeks.

However, a medium project may be 12- 14 weeks.

A large extension that involves a lot of renovations to the existing house may take even longer; especially if they involve a second storey, 6–9 months might be a more realistic time frame in that case.

Once again your building company will be best placed to advise on time frames.
