Library Bookcases Designed for Brighton Homes
A standard IKEA BILLY bookcase sits against your wall. A built-in BILLY bookcase becomes part of it, floor to ceiling, wall to wall, with no visible gaps and no flatpack feel.

I specialise in transforming BILLY systems into seamless library bookcases, precision-scribed to your exact walls and ceiling. In Brighton's period homes, where alcoves are rarely square and ceilings rarely level, that precision is what makes the difference between a bookcase that looks added on and one that looks original to the room.

Why Most IKEA BILLY Bookcases Don't Look Built-In
IKEA BILLY is well-made and versatile but when installed as standard, it almost always leaves visible gaps at the ceiling, uneven edges at the walls and an unmistakable flatpack feel. In Brighton and Sussex period homes, this problem is worse.
Alcoves that aren't square. Chimney breast recesses where the two sides sit at slightly different depths. Ceilings that slope or drop across the width of a room.
A standard BILLY installation doesn't account for any of it. The unit goes in, the gaps stay, and the bookcase looks temporary rather than architectural. The result is a bookcase that looks placed in the room rather than built into it.


The Finition Difference
I transform standard BILLY systems into seamless library bookcases — scribing every panel to your walls and ceiling, building custom infills to close every gap, finishing the installation so it reads as part of the room's architecture.
Where BILLY alone isn't the right choice, I combine it with the IKEA BESTÅ system. In the West Hove Arch project, two alcoves of different depths were unified into a single arched library wall using both systems together. The result is indistinguishable from bespoke joinery.
Every measurement is taken on site. Every infill cut to the exact contours of your space including the uneven walls and sloped ceilings Brighton period homes are known for.

Preparation
Once you've confirmed the quote, I'll advise you on the exact BILLY (and BESTÅ where needed) components to order from IKEA before the installation date.
03.
Professional Installation
I arrive on site with everything needed for the built-in finish, scribing tools, infill materials, fixings. The BILLY units go in first, then the scribing and infill work that closes every gap to your walls and ceiling.

The Built Finish
Before I leave, every panel is checked, every gap is closed and the installation is secured to the wall. What you're left with looks like it was built with the house.
