"Our rear extension was designed brilliantly — the light, the flow, the way it connects to the garden. Studio Helix handled everything from planning to sign-off and we're absolutely thrilled."

Common questions
For complex projects, planning applications and structural changes, a RIBA-chartered architect adds significant value — we understand planning policy, design principles and building regulations in depth. For simpler drawings only, a draughtsman may suffice.
