Harpenden House Extension Case Study

This house project exceeded our client’s expectations and created a space for their family to enjoy for years to come.

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 your home extension project or renovation will look. We’ll take this into consideration but also consider costs, planning constraints and buildability. There’s no point in 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 extension and this gives us the energy to go on.

Believe In Quality Design for Everyone

Good design and planning should not be limited to some Architects and designers 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 house extension project and conversion or renovation 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.
