Excellent service. Paul is very thorough and took his time to make his decisions and explain them to me. He is friendly and helpful and has a ‘can do’ attitude.

Would definitely recommend for any detailed drawings required, we got them in late in the day to provide building regs drawings, were really efficient in completing within the required timescales and went into a lot of detail to make sure everything was right.

I felt in very capable hands and expertly advised. I’d highly recommend Detailed Planning. Our new loft conversion has maximised the space available to us.

Understanding Your Project Goals

When we begin, we’ll take time to understand your brief, you may also have ideas of how the end product will look. We’ll take this into consideration but also consider costs, planning constraints and buildability. There’s no point designing something that can’t be built!

Striving to Create Quality Spaces

Our number one goal is to create spaces that meet requirements and go beyond the expectations of our clients. We love to hear that our clients are enjoying their new home and this gives us the energy to go on.

Believe In Quality Design for Everyone

Good design should not be limited to some Architects only. We are here to provide excellent architectural environments to all, at a more realistic cost compared with some architect fees.

Pushing Technical Detail

Every project is unique and ensuring it is buildable should be considered from the outset. Should we provide technical drawings, we’ll make sure risks on site are reduced by considering all parts of your project. This should lead to overall cost savings and minimised delays.

High Planning Success Rate

We never take on a project where the principle of the development seems unlikely to be approved. During the design, we’ll use our knowledge and check planning policies to give your application the best chance of success. We have worked with many authorities and understand how planning applications are decided.

Flexible Design Approach

We are not fixed to one design style; therefore we can be used for realist extension design to ultra contemporary. We will listen to your brief and design a bespoke extension meeting your needs.

Free Quote

Want to talk about your project? We will always check your enquiry to ensure there is a reasonable chance of success.

Our quotes are free and we can provide free office consultations should your project be viable.

Our Process

1. Design

Whether your family is growing, and you need an extra bedroom, or you want a new, bright, modern open-plan living, we can help find a solution to maximise your space. Here at Detailed Planning, we have a team of trained designers who are specialised in creating unique spaces for all types of briefs. We understand the cost of developing a property, so we’re sensitive to our costs and guidance. We aim to help you stretch your money enough for the best results!

3. Technical

Our design team carries out the detailed technical drawings at this stage. We provide extra detail so your builder can construct your project with the quality it deserves. Remember, a detailed set of drawings is crucial for a project to go accordingly.

4. Ready. Set. Go

Frequently Asked Questions About Finchley Loft Conversions

What is the average cost of a loft conversion?

The cost of a loft conversion in the UK can vary widely depending on various factors, such as the size and complexity of the project, the location, and the materials used. You can speak to our team here at Detailed Planning if you would like a bespoke quote.

Do I need permission for a loft conversion?

In most cases, you will not need planning permission for a loft conversion in the UK, but it depends on several factors, including the loft conversion type and location. It is recommended to check with your local planning authority or consult a professional to determine if planning permission is required for your specific project.

How long does it take to convert a loft?

On average, a loft conversion can take 4 to 10 weeks, but larger or more complex projects can take longer.

Do I need to tell my neighbour about the loft conversion?
You may not be required to inform your neighbour about a loft conversion, but it is recommended to do so as a courtesy. If the loft conversion affects your neighbour’s property in any way, such as during construction or blocking their view, you may need to obtain their consent or inform them of the plans.
Can a neighbour object to a loft conversion?
Yes, a neighbour can object to a loft conversion if they have concerns that the project may adversely affect their property in some way, such as blocking their view or causing damage. However, their objection may not necessarily stop the loft conversion if it meets all the planning and building regulations requirements.
Do I need an architect for a loft conversion?
An architect can help you design a loft conversion that maximises the available space, enhances the aesthetics of your property, and meets your specific requirements and preferences. Additionally, an architect can provide technical drawings, specifications, and project management services to ensure your loft conversion is completed to a high standard and within the required timeframe and budget.
