House Extension Process
CK Architectural Cheltenham delivers a full design and support service for house extensions of every type and scale. We start with a consultation to understand your goals, assess your property, and identify any planning or legal requirements.
Once we have a clear understanding of your needs, we develop detailed design proposals tailored to your space and lifestyle. From there, we produce accurate planning and building regulation drawings that can be used to secure approvals and inform your builder. If you would like additional support, we can assist with selecting a builder, reviewing quotes, and overseeing the project on your behalf.
Our aim is to deliver an extension that enhances your home in every way while taking the stress out of the process.
Some of the most influential factors are:
- Affordability
- Planning Constraints
- Buildability
- Lighting
- Neighbours
- Visual Impact
We offer a free consultation in the comfort of your own home and offer all the advice you will need.
You will get the best design options so that you can make the right choices
Types of House Extension in Cheltenham
There are several different types of house extensions, each suited to different property layouts, budgets and lifestyles.
Rear extensions are a popular option in Cheltenham, especially for homeowners looking to create open-plan kitchen and living spaces that connect with the garden. These are particularly effective in semi-detached and detached homes with generous outdoor space.
Side return extensions work well for Victorian and Edwardian terraces, making use of the narrow alleyways often found beside the kitchen to widen internal layouts and improve flow.
Wraparound extensions combine both rear and side elements to create a larger footprint. These can transform the ground floor of a property, allowing for dramatic reconfigurations and plenty of natural light.
Cheltenham Extension planning permission
Some extensions may be built without planning permission under permitted development rules, but many properties in Cheltenham fall within conservation areas or have other constraints that require full planning consent. We assess your project early to determine what permissions are needed and help you take the correct approach.
Our planning packages include all the necessary drawings and documentation to support your application, including location maps, site layouts, elevations and design statements if required. We liaise with Cheltenham Borough Council on your behalf and keep you updated on the progress of the application throughout the process.
If a planning application is not required, we can still apply for a lawful development certificate for added peace of mind and future resale value.
Building regulations for house extensions
Once planning approval is in place, we move forward with the technical side of the project. Building regulations approval is required for almost all extensions, and we provide full building control drawings that set out how the extension will be built in line with national standards.
Our drawings include information on structure, insulation, drainage, ventilation, fire safety and other critical factors. These are used to obtain quotes from builders and are checked during construction by a building control officer. We also work with structural engineers where necessary to ensure the extension is fully compliant and safe.
Building your home extension
Once you have your plans approved, you can move on to tender and build. Our detailed drawings will be enough for any competent builder to price and build from, and we advise using these drawings to form part of the quotation along with the written builder quote. We can help by recommending local builders or even manage the project ourselves through out project management.
Our suggestions in this instance would be:
- Make sure your builder has the relevant experience, references, and availability to build your single storey extensions.
- Choose someone you would feel comfortable working with and talking to about concerns.
- Be clear about your timescale expectations and specific finishes
- Extension plans for building regulations will not complete the items in the work contract.
- Quotations should be clear and easy to read, referencing our detailed approved building regulations drawings.
- Ask who will be doing the work, will they be subcontracting and who is responsible.
- Make sure you know when you need to paycheck their payment structure and be comfortable with it.
- Don’t always go with the references they give you, it’s not hard to find out where else they may have been working.
Alternatively, our complete project management service does apply here too. We’ll be dealing the builders first-hand so that you don’t have to, dealing with all progress, issues and concerns on your behalf as approved by yourself, taking the stress of building management away.
We try to add as many construction details as possible at the building regulations stage, but some assumptions have to be made and certain areas investigated before moving forward. Make sure to remedy them pre-building to avoid any costly surprises (unless we’re managing your project for you). We offer help throughout, for both you and your builder, we will come to the site if help is required.

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.
CK Architectural where very thorough, professional and prompt when drawing up our plans, providing options and guidance when choosing & deciding what would work best with the space created. Any additional questions/queries where also answered straight away and always provided useful information. Very pleased with the service received and have recommended to friends and family.

Great service - innovative thinking and timely responses. Can’t wait for the next project they can help me with! Would not hesitate to recommend.
Enjoyed working with CK on our loft conversion, kept us updated along the way and very happy with the outcome and the service. Would highly recommend
I have used CK Architectural for numerous project over the past few years and find them to be attentive, conscientious and very reliable. And most of all they offer excellent value for money.
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.
Proffesional, helpful & a great price. Produced hard copies & electronic of everything we needed. What more could you ask for .
Chris’ attention to detail and professionalism was second to none. I would highly recommend him and his Company.
Brilliant company, great service from start to finish, cant recommend highly enough.
