Our Approach
How do our services work?
01
Initial Consultation & Proposal
Your journey begins with an initial consultation, which can take place via phone, Teams, or a site visit. During this meeting, we’ll discuss your ideas, review your site or property, and gather all relevant information. From this, we prepare a detailed fee proposal, outlining the scope, services, and next steps, so you know exactly what to expect.
02
Concept Design & Planning Preparation
Once appointed, we develop concept sketches based on the information gathered and refine them with you through one or two meetings, calls or emails. Once approved, we produce detailed digital drawings for planning submission and liaise with any required consultants, managing the application from start to finish.
03
Building Regulations & Technical Preparation
After planning approval, we produce building regulations drawings, which include detailed technical specifications. At this stage, we bring on board a structural engineer and energy assessor as needed, and submit the complete package to Building Control for approval. This ensures your project complies with all legal and safety requirements.
04
Tendering & On-Site Design Support
Once Building Control approval is obtained, we tender the project to carefully selected contractors. During construction, we provide an on-site design guardian role, overseeing the build to ensure the design intent is delivered, coordinating with contractors, and addressing any on-site decisions until the project is completed to your satisfaction.

Frequently asked questions
Do I need planning permission for my project?
Likely yes – and it’s completely normal to feel unsure about this. Whether you need planning permission depends on the type, size, and location of your project. Many small extensions and alterations can be done under Permitted Development, but it’s not always straightforward. At Ellis+Company, we’ll carefully review your home and explain what’s required. With our 97% planning approval success rate and over 200 projects completed, we make the process simple, clear, and stress-free.
How long does the whole project take from start to finish?
Every project is unique, and timelines depend on the size and complexity of the work. Typically:
- Design & planning: 1–3 months
- Technical design & approvals: 1–2 months
- Tendering: 2–4 weeks
- Construction: 3–12 months
We’ll give you a tailored programme at the start and keep you updated every step of the way. With fifteen years of residential experience, we can anticipate potential issues before they arise, keeping your project on track and reducing stress for you.
How much will my project cost?
It’s a cliché, sorry, but costs vary widely depending on the size, materials, and complexity of your project, making it tricky to give an exact figure early on. We provide transparent competitive pricing upfront as soon as possible, covering construction, architectural fees, structural engineers and other third-party consultants, surveys, and planning/building control fees. With us, there are no surprises – you’ll always know what to expect.
Will my project add value to my home?
Most of the time, yes. Extensions, open-plan layouts, loft conversions, and modernised living spaces are among the most value-adding improvements. We design with both lifestyle and long-term investment in mind, drawing on our fifteen years’ experience to create spaces that are beautiful, practical, and future-proof.
What is the typical process of an architectural project?
We like to keep things simple and stress-free:
- Initial consultation & brief
- Measured building & site survey
- Concept design/sketches
- Planning application (if required)
- Technical drawings for Building Regulations
- Tendering to builders
- Construction & site support
With over 200 completed projects, we combine experience, technical expertise, and friendly guidance to make the process clear, smooth, and reassuring.
Do I need a structural engineer?
Very likely. If your project involves structural changes – like removing walls, extending, or converting a loft – the answer is yes. We coordinate with our recommended engineers to ensure safety, compliance, and efficiency, giving you peace of mind.
Can I live in my house during the works?
Often yes. Extensions and loft conversions are usually manageable while living at home. Major internal renovations may require temporary relocation, and we’ll help you plan around this. We aim to minimise disruption, keeping your home comfortable while work is underway. Ultimately, this will also need discussion with the contractor/builder when the time comes.
Do you help us choose a builder?
Yes. We have three recommended contractors we can tender to, along with any others you choose. We guide you to find the right builder, running a competitive tender process and assessing quality, cost, and timing. We currently work with two of the top ten nationwide housebuilders, so you can trust our recommendations. Our goal is to give you confidence and reassurance throughout construction.
