A purpose-built garden annexe or outbuilding conversion creates a private, independent dwelling right in your garden — perfect for rental income or multigenerational living.

We can create a fully self-contained annexe within your existing home footprint — a private entrance, kitchenette, bedroom, and bathroom for complete independent living.

Every ADU we build includes a fully fitted kitchen and bathroom — designed for practicality and finished to the same high standard as the rest of the build.

Frequently Asked Questions

How much does an ADU or in-law apartment cost in Worcester?
Costs vary depending on the type, size, and condition of the existing space. A garage conversion ADU typically starts from around £25,000, a garden annexe from £40,000, and a full new-build ADU or basement conversion from £55,000+. We provide a full, transparent quote before any work begins — no hidden costs.
Do I need planning permission for an ADU or annexe?
Many smaller ADUs and annexes within existing structures benefit from Permitted Development rights, but garden annexes, new-build units, and properties in conservation areas typically require full planning permission. We assess this during your free consultation and handle all necessary applications on your behalf.
How long does it take to build an ADU or in-law apartment?
Timescales vary by project type. A garage conversion typically takes 8–12 weeks. A garden annexe or new-build ADU generally takes 12–20 weeks depending on size and specification. We provide a clear project schedule before work begins and keep you updated throughout.
Can an ADU be used as a rental property?
Yes — a self-contained ADU with its own entrance, kitchen, and bathroom can be let as a separate dwelling, subject to planning conditions. We can advise on how to build your ADU to comply with rental and HMO standards from the outset, saving time and cost later.
Will an ADU add value to my property?
Yes — a well-built ADU or self-contained annexe can increase your property's value significantly, often by 20–30% or more depending on location and specification. The potential rental income also makes it an excellent long-term investment across Worcester and Worcestershire.
What areas do you cover?
We serve Worcester city and the wider Worcestershire area including Malvern, Kidderminster, Droitwich, Redditch, Bromsgrove, and Pershore.
