Designing a double storey extension

Our extensive experience in design allows us to help your dream double storey extension come to life. With just a few small details and a thorough analysis of your property and needs, we can get to work on making your house everything you want it to be.

It is highly likely that your double storey extension will require full Planning Approval from your local council, so we will investigate any potential restriction when designing your extension.

We will work with you and demonstrate different layouts to help you understand the functionality of the space available and create your house extension plans.

CK Architectural also offer 3D Visualisation to help you understand and explore the design of your double storey extension with complete clarity. Simply ask for more details when you’re ready.

Planning permission your home extension design

When you are planning and designing your double storey extension with CK Architectural, our Architectural Designers will take into consideration any restrictions such as impact on the neighbours and the surrounding area.

We will also take into consideration any obstacles that the planning department may throw at us, working closely with Sheffield and South Yorkshire council to keep your expectations real, viable, and achievable to create your double extension.

When grey areas do arise, we can work with you and the council to write a tailored planning statement, alas, some restrictions are “set in stone” and we will not be able to work around them.

This situation will depend on your circumstances individually, and we will be happy to advise. Simply get in touch to speak to an expert.

This is the second project I have used CK Architects on and I wouldn’t hesitate to use them again or to recommend them to others. Karen is highly professional, friendly, and quick, listened to our requirements and acted on everything so beautifully. We are very impressed with the fast, efficient service provided by CK Architectural Design staff members.

Exactly what I wanted. No sales rubbish, no broken promises. They did exactly what I asked for, right first time, for the exact price quoted. I'd definitely use the company again.

Excellent service and communication. The company correctly and quickly identified my requirements, and worked accurately and within (very reasonable) quotation. Any queries and additional dimensions or details which the design engineer had, were clearly requested, allowing me to be able to quickly furnish the exact information and measurements, and negating the need for site visits, thus keeping costs in check. The first draft of the engineering drawings were very impressive - as a project engineer involved in the materials handling industry, I am well used to working with and interpreting CAD drawings, so was able to appreciate the high level of detail and clarity therein. I have been pleased and impressed with the service provided and care taken by CK Architectural, in bringing this part of my project to a successful conclusion - the Local Authority Building Control department accepted the drawings and specifications at first draft, without any amendments or changes. I am happy to recommend this company to anyone seeking a friendly, helpful, skilled and professional service.

CK Architectural led us through our whole project of two significant extensions from start to finish. At the outset during concept the input was both practical and creative. Several of our own ideas were improved upon and other ideas added. The creation of the designs was collaborative with CKA listening to our needs and wishes and incorporating them as practically possible. The budget was agreed with CKA and they kept a tight lid on the finances. The initial plan was actually built within budget, and we just crept over due to a couple of unforeseen changes, such as the roof tiles to match current being discontinued and therefore we chose to have a new roof. CKA made frequent visits to site and it always felt as if they had the project under control. It is not until you embark upon a venture such as this, as a novice, that you realise how complex it all is. However, with CKA leading the way on drawing completion, obtaining planning permission, appointing reputable contractors and managing Building Control eveything felt smooth and was stress free for us as the client. For the service we received we thought CKS priced their involvement very fairly.

For someone far removed from the building / planning industries the thought of where to start when thinking of a big extension project to my house (two story to the side and wrap around of semi-detached 3 bed) was a little daunting at first. Luckily, after obtaining a competitive quote, I enlisted the services of CK Architectural and have been very impressed with not only the service received but the ease at which they have made the whole process. After listening to my thoughts and the reasons for needing the extension work doing, the architect came up with a great design that encompassed everything that was needed. Even when I changed my mind over a couple of aspects, Donna, Chris and the team were quick to administer any alterations. Every visit to the house for measurements / planning etc has happened without a hitch with all members of the team we've encountered being punctual and professional at all times. The best thing has been by far the ease at which CK have made of getting all council and local authority sign off for the project. All I have needed to do is pay the fees at the required time, no stress involved and all went through seamlessly. I'm now at the stage where I have the drawings to hand and have submitted them to builders to obtain quotes. Importantly, the feedback so far from the builders indicates the project to be within the budget specifications I explained to CK during the first consultation. Very happy customer 🙂 Carl.

Positive: Professionalism, Quality, Responsiveness, ValueHighly recommend CK Architectural. Chris and his team did a great job gaining planning permission for a new build and renovation of an existing property. We hit some dead ends with the planning officer but Chris found different ways of getting around the problems without going over budget.

We have use the team at CK Architectural on 2 projects of ours over the years. They have never let us down. They have always worked with us to produce the designs we wanted and handled everything for us through the Planning and Building Control stage, keeping us updated at the carious stages. We will most certainly use again if we decide to do another project.

Project management for your double storey extension

Finding Builders, checking quotes and checking contracts can be a stressful time and that’s before your build has even started.

For peace of mind and reassurance, you can always choose to get a 3rd party to project manage your double storey extension.

CK Architectural offer a Project Management service where they will manage the project from start to finish, removing the stress of finding a trusted builder and ensuring they stay on time, on design and on budget.

You will be regularly informed of the progress and costings involved in your project, and only need to talk with us rather than the builder. Nothing is left to interpretation as we manage who gets paid after checking that they have reached the agreed stage and to the agreed standard, saving time, money, and stress collectively.

Notes for building your home extension

Your detailed home extension plans allow any competent builder in Sheffield and South Yorkshire to price and build correctly. You will get accurate quotations from them if they asses the site as well.

Although we will do our best to warn or design against potential building issues, when a build takes place sometimes issues do arise from aspects not undertaken by ourselves. It is worth remembering we cannot see underlying issues behind walls or underground.  You should make allowances for this and ensure that the builder prices for issues if they arise.

Be aware to look out for poor ground and drainage and make sure the builder undertakes a CAT scan before excavation.

With the larger projects let CK Architectural take care of the administration and preparation with our project management team.
