Basements

A basement conversion can create a range of possibilities within your home, from a simple spare room to an entire new storey. It is also ideal for homeowners looking for more room without compromising on their outdoor space.

Additionally, depending on the scale of your project, planning permission may not be required. We can advise on this process and the different options that will affect your planning application.

Many people assume that their basement can’t be used as a suitable living area yet our expertise allows us to design warm, light-filled basement conversions that add depth and character to your home.

Established in 2011 we have been providing architectural services for all types of residential projects, working alongside homeowners, builders and developers. So, if you’re a homeowner looking to open up your home and create more room, or if you are a developer looking to maximise property potential, we will ensure your needs are met.

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. 

Why Choose 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 build ability. 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.

Questions to Ask Your Designer

1. How much experience do you have?
Detailed Planning have completed hundreds of successful projects, from small extensions to large glazed modern extensions. We are up to date with planning and regulation policies to help avoid bumps in the process.
2. Have you worked within my local borough?
We’ve worked within every London Borough as well as the surrounding counties; this means we have excellent knowledge of what’s likely to be approved. Should we work further afield, we’ll make sure we’ll study the policies to determine if the development is feasibly, before proceeding.
3. Do you have liability insurance and a quality control process?
Our company has liability insurance of up to £1,000,000. To reduce risk, as well as using our depth of knowledge, we have a team to check others work prior to issue of any documents.
4. Will you manage all the pre-construction approvals?
The project will usually involve multiple approvals, not just planning consent. This will likely include, building control plan check approval, party wall agreements as well as structural calculations.
5. Will you assist with liasing with other consultants?
Yes, we will ensure that all the necessary consultants are instructed and are carrying out their duties. We discuss the project with them directly and make sure they have everything they need.
