Transform Unused Attic Space into a Functional, Beautiful Room

​

Looking to make the most of your home’s existing structure? An attic conversion is a cost-effective and practical way to add valuable living space without extending the footprint of your home.

​

At Draw Plans, we provide fixed-price attic conversion plans starting from just £995 + VAT, designed for homes across London and the Home Counties. Our expert team creates detailed architectural drawings tailored to your home, layout goals, and planning requirements — ready for submission and construction.

​

What Is an Attic Conversion?

An attic conversion involves turning the unused space beneath your pitched roof into a usable room — such as a bedroom, home office, playroom, or guest suite. Unlike traditional loft conversions, attic conversions often use the existing roof shape and structure, making them faster and less intrusive in many cases.

​

Whether your home is semi-detached, terraced, or detached, an attic conversion can be designed to enhance your living experience and increase property value.

​

Benefits of Attic Conversions

Create Extra Space Without Moving
Add a new room without needing a full extension or costly relocation.

​

Increase Property Value
A high-quality attic extension can boost your home’s value by up to 20%.

​

Perfect for Growing Families
Turn your attic into a teenager’s bedroom, guest suite, or quiet home office.

​

Quick and Efficient to Build
Many attic conversions can be completed in 6–8 weeks with the right planning and design.

​

Planning Permission Not Always Required
Depending on the scope, many attic conversions fall under permitted development.

Attic Conversion Ideas & Layout Tips

The key to a successful attic extension is smart design. Here are some ideas and tips to make the most of your conversion:

​

Popular Attic Conversion Ideas:

• Main bedroom with en-suite

• Home office with built-in storage

• Guest bedroom or teen retreat

• Playroom or hobby space

• Quiet reading nook with skylights

​

Design Tips:

• Use rooflights or Velux windows to maximise daylight

• Install built-in wardrobes in eaves to save space

• Choose a compact, space-saving staircase (like paddle stairs if permitted)

• Ensure minimum head height of 2.2m in the main room area

• Place bathrooms near existing plumbing for cost efficiency

• Insulate thoroughly to meet modern energy efficiency standards

​

Planning Permission for Attic Conversions

In many cases, an attic conversion falls under permitted development, especially if no major changes to the roofline are made. However, you may need planning permission if:

• You're in a conservation area

• You're raising the roof height

• You're installing large dormer extensions

​

Draw Plans can advise on your situation and handle the planning application on your behalf, if required.
